Sounding Stick: Meaning, Risks & Safety Information
A sounding stick, more commonly called a urethral sound, is a smooth rod designed to enter the urethra, the tube that carries urine out of the body. In clinical medicine, specially designed sounds have historically been used by trained healthcare professionals to assess or dilate narrowed sections of the urethra. The term is also used for devices sold for personal or sexual use, which creates important safety considerations because the urethra is delicate and vulnerable to injury. Improper insertion can cause pain, bleeding, infection, scarring, or difficulty urinating. Understanding what these devices are is therefore more important than treating them as ordinary accessories. Any use involving the urinary tract requires careful attention to hygiene and anatomy.
The urethra contains sensitive tissue that can be damaged more easily than many people realize. A device that is too large, rough, contaminated, sharply edged, or inserted with force can scratch or tear the lining. Even a small injury can create an entry point for bacteria and increase the risk of a urinary tract infection. Repeated trauma may lead to scar tissue that narrows the urethra, a condition known as a urethral stricture. In severe cases, a retained object, significant bleeding, urinary blockage, or deeper tissue damage can require urgent medical treatment. These possibilities make safety information essential when discussing urethral sounding.
People sometimes encounter the term sounding stick online without understanding whether it describes a medical instrument, an adult product, or an improvised object. Medical urethral sounds are manufactured in controlled sizes and shapes and are used for specific clinical reasons. Household objects, wires, pens, needles, rigid tubes, or other improvised items are not substitutes because they may contain rough edges, coatings, bacteria, or shapes that can become trapped. Even commercially manufactured products are not automatically risk-free. Material quality, sterilization, lubrication, size, technique, and individual anatomy all affect the likelihood of complications.
A person experiencing urinary symptoms should not use a sounding device as a way to diagnose or treat themselves. Painful urination, weak urine flow, blood in the urine, inability to urinate, discharge, fever, pelvic pain, or recurrent urinary tract infections can have many causes that require proper medical evaluation. Trying to open a suspected narrowing without professional guidance may worsen the problem. Urologists have specialized instruments and imaging techniques that allow them to investigate the urethra more safely. Medical dilation, when needed, is performed according to specific clinical indications rather than simply because a person feels resistance.
This guide explains the sounding stick meaning, medical background, potential risks, hygiene considerations, warning signs, and general safety information in straightforward language. It is intended for education rather than as instructions for inserting a device. The safest approach for anyone considering urethral instrumentation, particularly someone with urinary symptoms, previous surgery, recurrent infections, or urethral disease, is to discuss the issue with a qualified healthcare professional. Understanding the risks does not eliminate them, but it can help people recognize dangerous practices and seek care sooner when complications occur. Urethral health deserves the same caution as any other sensitive medical issue.
What Is a Sounding Stick?
A sounding stick is a rod-shaped instrument associated with insertion into the urethra. In medical terminology, these instruments are generally referred to as urethral sounds rather than sounding sticks. They have traditionally been used by healthcare professionals in procedures involving examination or dilation of the urethra. The shape, length, curvature, and diameter can vary depending on the intended clinical application and anatomy involved. Medical instruments are designed with smooth surfaces because irregularities could damage delicate urethral tissue. The basic purpose is fundamentally different from inserting an ordinary object that was never designed for contact with the urinary tract.
The word “sound” has a long medical history and is not connected to hearing or audio. In this context, it refers to a type of probe or instrument used to explore a body passage. Different forms of sounds have been used in urology for many years, particularly when evaluating narrowing of the urethra. Modern urology also uses technologies such as endoscopy, imaging, catheters, guidewires, and specialized dilation devices depending on the problem being treated. A traditional sound therefore represents only one tool within a much larger field. Its use should not be interpreted as a simple procedure suitable for every person.
Personal-use products marketed as urethral sounds may be made from stainless steel, silicone, or other materials. Their appearance can resemble straight or slightly curved rods available in different diameters. However, the fact that a product is commercially available does not prove that it is appropriate for a particular person’s anatomy or health status. Product quality can vary, and poor manufacturing may introduce seams, roughness, contamination, or questionable materials. The urethra is not designed to tolerate uncontrolled instrumentation. Choosing a professionally manufactured device may reduce some hazards compared with improvised objects, but it cannot eliminate the underlying medical risks.
The anatomy of the urethra also differs between people. In people with a penis, the urethra is relatively long and passes through several anatomical regions before reaching the bladder. In people with a vulva, the urethra is much shorter and has a different orientation. Previous surgery, congenital differences, inflammation, infection, scar tissue, prostate conditions, and other medical factors can further change how the urinary tract behaves. A size or shape that appears suitable based on someone else’s experience may therefore be inappropriate for another individual. This is one reason generalized internet advice about urethral insertion can be unsafe.
The most important distinction is between medical urethral sounding and non-medical self-insertion. Medical procedures are performed for a defined reason using controlled equipment, sterile technique, anatomical knowledge, and access to treatment if complications occur. Self-use lacks many of these safeguards, particularly when people experiment without understanding the urinary tract. Problems can develop even when no immediate pain is felt. Tissue irritation, minor bleeding, bacterial introduction, or repeated stretching may have consequences that become noticeable later. Treating the practice as a medical-risk activity rather than a harmless novelty creates a more accurate understanding of what is involved.
Why Are Urethral Sounds Used in Medicine?
One traditional medical use of urethral sounds is the evaluation or treatment of a urethral stricture. A stricture occurs when scar tissue narrows part of the urethra, making it harder for urine to pass. Symptoms can include a weak stream, spraying, straining, incomplete emptying, recurrent infections, or urinary retention. Healthcare professionals may use specialized instruments to determine the location or severity of narrowing. Depending on the condition, treatment can involve dilation, endoscopic procedures, reconstructive surgery, or other approaches. The appropriate method depends on the patient’s anatomy, medical history, and the nature of the narrowing.
Urethral dilation involves gradually increasing the diameter of a narrowed urethral segment. Historically, sounds of progressively larger sizes were frequently used for this purpose. Modern urologists may instead use specialized dilators or other techniques depending on the situation. Dilation is not necessarily a permanent cure because some strictures can recur after treatment. People may therefore need follow-up assessment or a different intervention if narrowing returns. The decision to perform dilation should be based on a confirmed diagnosis rather than symptoms alone.
Medical instrumentation requires careful infection prevention. The urinary tract can become infected if bacteria are introduced during a procedure, which is why clinical environments follow cleaning, disinfection, sterilization, and aseptic protocols appropriate to the device and procedure. Healthcare professionals also consider whether a person has signs of an existing urinary infection before instrumentation. Introducing an instrument through inflamed or infected tissue can potentially worsen complications. Some procedures may require urine testing or additional precautions depending on the patient’s health. These safeguards illustrate why medical instrumentation is different from casual self-use.
Clinicians also know how to recognize anatomical resistance and signs that a procedure should not continue. Resistance may indicate narrowing, abnormal anatomy, inflammation, or another problem rather than simply a need for more pressure. Forcing an instrument can create a false passage, meaning the device tears into tissue instead of following the normal urethral channel. This is a significant injury that can cause bleeding, pain, scarring, or urinary complications. Trained professionals use tactile feedback, visualization, imaging, or guidewires when appropriate. This expertise cannot be replaced simply by purchasing an instrument online.
If someone believes they need urethral dilation because urine flow has changed, they should seek a urological assessment rather than attempting self-treatment. Similar symptoms can result from prostate enlargement, infection, bladder problems, neurological conditions, stones, strictures, medications, or other causes. Treating the wrong condition may delay appropriate care. A urologist can perform tests such as urine analysis, flow measurements, imaging, cystoscopy, or other evaluations depending on the symptoms. Accurate diagnosis comes before treatment. That principle is especially important when the proposed treatment involves placing an instrument into a delicate body passage.
What Are the Main Risks of Using a Sounding Stick?
The most immediate risk is urethral trauma. The lining of the urethra can develop abrasions, small tears, or more significant injuries when an instrument creates excessive friction or pressure. Pain and bleeding may occur immediately, although minor damage can sometimes produce only subtle symptoms. Injured tissue can swell, making urination uncomfortable or difficult. More severe trauma can create a false passage or damage deeper structures. Continuing after feeling sharp pain, significant resistance, or unexpected discomfort increases the chance of injury rather than making the urethra adapt safely.
Infection is another major concern because inserting any object can carry bacteria into the urinary tract. A urinary tract infection may cause burning during urination, urgency, frequent urination, cloudy or unusual-smelling urine, lower abdominal discomfort, or blood in the urine. If infection spreads upward, symptoms can become more serious and include fever, chills, back pain, nausea, or systemic illness. Contaminated hands, inadequately cleaned devices, damaged surfaces, and reuse without proper sterilization can all increase microbial exposure. Even careful cleaning cannot guarantee that self-use will be free of infection.
Repeated injury can lead to scar formation and urethral stricture. Scar tissue is less flexible than normal urethral tissue and may gradually narrow the urinary passage. A person who initially uses sounding without obvious complications could later develop slower urine flow, splitting or spraying of the stream, straining, incomplete emptying, or recurrent infections. Ironically, repeated instrumentation can therefore create the type of narrowing that medical dilation is sometimes used to treat. Established strictures may require specialized urological management. Persistent changes in urinary flow should not be ignored.
A device can also become stuck or migrate farther into the urinary tract than intended. Objects that are too short, poorly shaped, slippery, flexible in unpredictable ways, or not designed with safe retrieval in mind can become difficult to remove. Attempting to retrieve a retained object with additional tools can cause further injury. Healthcare professionals may need imaging, endoscopy, anesthesia, or surgery to remove foreign bodies safely. Embarrassment should never delay emergency care because the risk of infection, perforation, and tissue damage can increase with time. Medical staff are trained to manage these situations professionally.
Rare but serious complications can include significant bleeding, urethral perforation, severe infection, inability to urinate, and damage involving the bladder or surrounding structures. A medical emergency is more likely if severe pain, continuous bleeding, fever, abdominal swelling, inability to pass urine, dizziness, or signs of systemic illness develop. These symptoms should not be treated with repeated attempts at insertion or home remedies. Prompt assessment can reduce the likelihood of long-term damage. Even seemingly minor symptoms deserve evaluation when they persist after urethral instrumentation.
Infection and Hygiene Risks With Urethral Sounding
The opening of the urethra is naturally exposed to microorganisms from surrounding skin and the environment. Introducing an instrument can push those organisms deeper into the urinary tract. This is why sterile or appropriately processed instruments are essential during medical procedures. Simply rinsing an object with water does not make it sterile. Household disinfectants may also leave irritating chemicals behind or damage materials in ways that create microscopic roughness. Infection prevention requires more than making an instrument look clean.
Hand hygiene is another important consideration because hands can transfer bacteria directly to the urethral opening or device. Healthcare professionals clean their hands and use appropriate sterile or aseptic techniques depending on the procedure. Personal-use environments are much harder to control. Surfaces, towels, containers, lubricants, and storage areas can all become sources of contamination. A device that was clean when stored may no longer be safe if it comes into contact with an unclean surface. These factors explain why the urinary tract can become infected even when a person believes they were careful.
Lubrication matters because friction increases tissue damage, but the type of lubricant also matters. Products not intended for sensitive mucosal tissue may contain fragrances, irritants, warming agents, or ingredients that cause inflammation. Oil-based household products are not automatically suitable substitutes for sterile medical lubricants. Medical professionals use lubricating products specifically designed for procedures involving mucous membranes. Appropriate lubrication reduces friction but does not make forceful insertion safe. If resistance is present, adding more lubricant should not be used as justification to push harder.
Sharing urethral devices introduces additional infection concerns. A device that contacts blood, urine, genital secretions, or mucosal tissue can potentially carry microorganisms between people. Cleaning methods that may remove visible material do not necessarily eliminate all pathogens. Medical instruments intended for reuse are processed according to defined sterilization standards. Personal products may not be designed to withstand those processes. Sharing should therefore be avoided, especially when the equipment cannot be reliably sterilized according to manufacturer and medical-grade instructions.
Anyone experiencing symptoms of a urinary tract infection, sexually transmitted infection, urethral irritation, genital sores, discharge, or unexplained inflammation should avoid urethral instrumentation and seek medical advice. Instrumentation through already inflamed tissue may worsen pain and introduce organisms deeper into the urinary system. People with weakened immune systems may also face greater consequences from infection. Symptoms such as fever, chills, flank pain, vomiting, or feeling severely unwell can indicate a more serious urinary infection. Those signs warrant prompt medical evaluation rather than waiting for the problem to resolve on its own.
Safety Considerations Before Any Urethral Instrumentation
The safest option for a person with a medical concern is professional evaluation rather than self-instrumentation. If urethral dilation is medically necessary, a clinician can select the appropriate technique based on anatomy and diagnosis. This matters because resistance can have several causes, including stricture, inflammation, structural abnormalities, or previous injury. Attempting to overcome an unknown obstruction can make the underlying problem worse. People with previous urethral surgery, pelvic trauma, recurrent infections, catheter complications, or known strictures should be particularly cautious. Their anatomy may require individualized care.
Improvised objects should never be treated as acceptable urethral instruments. Pens, pencils, wires, needles, knitting tools, drinking straws, electrical cables, screws, tubing, household rods, and similar objects may contain seams, sharp edges, coatings, or parts that can break. Some can also migrate into the bladder or become difficult to retrieve. Materials that look smooth to the eye may become rough when exposed to moisture or chemicals. Medical-grade instruments are specifically manufactured for controlled anatomical use. Substituting an ordinary object dramatically increases uncertainty and risk.
Any device intended for urethral contact should have a smooth, intact surface without cracks, chips, sharp edges, corrosion, or damaged coatings. Materials should be compatible with proper cleaning and, where appropriate, sterilization. Porous or difficult-to-clean materials can retain microorganisms. Devices with detachable pieces or unpredictable flexibility create additional concerns because parts can separate or fold inside the urinary tract. Manufacturers’ instructions should be followed carefully. A product that cannot be reliably identified, cleaned, or inspected should not be introduced into the urethra.
Pain should never be interpreted as proof that an instrument needs to be pushed farther. Sharp pain, significant burning, unexpected resistance, bleeding, or a sudden change in sensation are warning signs to stop. The urethra should not be treated like a rigid tube that can simply be stretched through force. Force can tear tissue and create a false passage instead of passing through the natural channel. A person who repeatedly encounters resistance should seek medical assessment. Continuing may convert a manageable problem into an injury requiring more complicated treatment.
Alcohol, recreational drugs, or medications that significantly impair judgment can increase risk because they may reduce awareness of pain or encourage forceful behavior. Reduced sensation can make it easier to miss early signs of tissue damage. Good decision-making is particularly important with activities involving delicate internal structures. Someone should also avoid urethral instrumentation when they cannot access medical care if complications occur. The possibility of urinary retention or a retained object means emergency treatment may sometimes be necessary. Risk management includes considering what happens if something goes wrong, not only what happens when everything goes as planned.
Warning Signs and When to Seek Medical Care
A small amount of temporary irritation can occur after urethral instrumentation, but persistent or worsening symptoms should not be dismissed. Increasing pain, burning urination, swelling, blood in the urine, or continued urethral bleeding may indicate tissue injury. Significant bleeding is especially concerning because the urethra contains blood vessels that can be damaged by trauma. People sometimes hesitate to seek care because they feel embarrassed about explaining what happened. Healthcare professionals routinely treat foreign-body injuries and urinary complications. Accurate information helps them choose the safest evaluation and treatment.
Inability to urinate is an urgent warning sign. Swelling, bleeding, obstruction, or urethral damage can interfere with urine flow after instrumentation. A painfully full bladder combined with little or no urine output requires prompt medical evaluation. Repeatedly inserting another object to “open” the passage can make the problem substantially worse. Clinicians may need to assess the urinary tract and determine a safe way to restore drainage. Prolonged urinary retention can damage the bladder and kidneys, so it should not be managed by waiting indefinitely.
Fever, chills, worsening pelvic discomfort, back pain, nausea, or feeling unusually weak can suggest that an infection is becoming more serious. A urinary infection can occasionally spread beyond the lower urinary tract. People with diabetes, immune suppression, kidney problems, or other medical conditions may be more vulnerable to complications. New systemic symptoms after urethral instrumentation should therefore be taken seriously. Medical evaluation may include urine testing, blood tests, imaging, or other examinations depending on the severity. Antibiotics should only be taken when appropriately prescribed because symptoms can have several causes.
A retained or broken object requires professional medical care. Attempting removal with tweezers, pliers, magnets, wires, or another inserted object can push it deeper or cause additional tearing. Clinicians may use imaging to determine the object’s location before removing it with specialized instruments. Some cases can be managed through endoscopic techniques, while more complicated situations may require surgery. The earlier an object is assessed, the easier removal may be. Delaying because of embarrassment can increase swelling, infection, and tissue damage.
Long-term changes in urination also deserve attention even when the initial event seemed minor. A progressively weaker urine stream, difficulty starting urination, spraying, prolonged emptying, recurrent infections, or the feeling that the bladder does not empty completely can indicate a developing stricture. Scar tissue can form gradually after injury. A urologist can investigate these symptoms and discuss appropriate treatment. Early evaluation may prevent more severe obstruction. Any persistent urinary change following urethral sounding should therefore be considered medically relevant.
Can Urethral Sounding Cause Long-Term Problems?
Repeated urethral trauma can have consequences that last well beyond the original episode. One of the most important long-term complications is urethral stricture disease. When damaged tissue heals, scar formation may reduce the diameter of the urethral passage. The degree of narrowing can vary from mild to severe. Some people notice only a slower urine stream initially, while others eventually struggle to empty the bladder. Strictures can recur even after treatment, making prevention of avoidable urethral injury especially important.
Chronic inflammation and repeated infections can also affect quality of life. Someone experiencing recurrent urinary discomfort may develop frequent urgency, burning, pelvic pain, or anxiety about urination. Repeated antibiotic exposure may become necessary if bacterial infections occur, although symptoms should always be properly evaluated before treatment. Persistent inflammation can complicate interpretation of later urinary symptoms because several conditions may produce similar discomfort. A history of instrumentation is useful information for a clinician. Patients should feel able to disclose it without fear of judgment.
Scar-related obstruction can affect the bladder over time. When the urethra becomes significantly narrowed, the bladder may need to generate greater pressure to push urine through the restricted passage. Long-standing obstruction can contribute to incomplete emptying and urinary retention. Residual urine can also create an environment where infections are more likely to develop. Severe or prolonged obstruction may eventually place stress on the upper urinary tract. These possibilities explain why persistent weak flow should not simply be accepted as a normal consequence of sounding.
Psychological consequences can occur after an injury as well. A painful complication or emergency removal procedure may create anxiety about urination, medical examinations, or sexual health. Some people avoid seeking care because they worry about stigma or embarrassment. Delayed treatment can make physical problems more difficult to manage. Medical professionals are expected to approach these situations clinically and confidentially. Giving an accurate history, including what object was used and when symptoms began, helps clinicians provide safer treatment.
Long-term complications are not inevitable, but they are possible enough that repeated urethral instrumentation should never be considered completely harmless. Risk depends on factors such as technique, device quality, frequency, existing medical conditions, previous injuries, infection exposure, and individual anatomy. Someone who has developed symptoms after sounding should stop further instrumentation until the problem has been assessed. Continuing through pain or difficulty may cause cumulative injury. Prevention is far easier than managing established scarring or chronic urinary problems.
Sounding Stick Myths and Common Misunderstandings
One common misconception is that discomfort means the urethra is simply “stretching” and that continuing will eventually make the activity safer. Pain is actually an important protective signal. Significant resistance or sharp discomfort may indicate friction, tissue injury, narrowing, or incorrect positioning. Forcing an instrument through resistance can cause tearing rather than controlled expansion. Medical dilation uses specific techniques and measurements because uncontrolled stretching is not equivalent to treatment. Ignoring pain increases risk rather than demonstrating progress.
Another myth is that an object is safe if it looks smooth. Microscopic scratches, seams, manufacturing defects, corrosion, coatings, or damaged surfaces may not be obvious to the naked eye. Household objects may also contain materials that are unsuitable for contact with internal tissue. A smooth-looking pen or wire is not designed to withstand medical sterilization or anatomical insertion. Material composition matters because some substances can irritate tissue or trap microorganisms. Appearance alone cannot determine whether an object is medically appropriate.
Some people believe washing a device with soap or alcohol makes it sterile. Cleaning and sterilization are different processes. Cleaning removes visible material and reduces contamination, while sterilization is designed to eliminate microorganisms using validated processes. Not every material can safely tolerate medical-grade sterilization. Harsh chemicals can also leave residues or damage surfaces. Medical facilities follow detailed processing requirements because microbial contamination cannot be reliably judged by appearance or smell.
Another misconception is that the absence of immediate bleeding proves no injury occurred. Small abrasions or internal tissue damage may not produce visible blood at first. Infection or swelling can develop later, and scar formation may take weeks or months to become noticeable. A person may therefore initially feel fine and later experience weaker urine flow or recurrent irritation. Delayed symptoms should still be taken seriously. Past instrumentation remains relevant even if significant time has passed since the activity occurred.
Finally, a sounding stick should not be viewed as a home treatment for difficult urination. Narrow urine flow requires diagnosis before any attempt at dilation. Prostate conditions, infection, stones, neurological problems, bladder dysfunction, medication effects, and urethral strictures can produce overlapping symptoms. Treating a suspected stricture without knowing whether one exists can delay proper care and cause additional damage. Urologists can identify the cause using appropriate testing. Self-treatment is particularly risky when the symptom itself may indicate an existing obstruction.
How to Protect Urethral and Urinary Health
The most effective way to protect urethral health is to minimize unnecessary trauma. The urinary tract performs a critical function and its tissues are not designed for repeated uncontrolled instrumentation. Anyone who requires urethral procedures for a medical condition should follow instructions from their urologist or other qualified healthcare professional. People performing intermittent self-catheterization for legitimate medical reasons should use the specific equipment and technique taught by their clinical team. Medical self-catheterization is fundamentally different from recreational sounding. The distinction matters because equipment, indication, training, and follow-up are all controlled.
Pay attention to changes in urine flow and urinary sensation. Burning, increased frequency, urgency, difficulty starting, spraying, weak stream, blood in the urine, unusual discharge, or incomplete emptying can signal infection, inflammation, or obstruction. Symptoms lasting more than a short period deserve professional assessment, particularly after instrumentation. Keeping track of when symptoms began and whether they are improving can help the clinician. Avoid repeatedly testing the urethra with another object. Further manipulation can make it harder to determine what originally caused the problem.
Hydration supports normal urinary function, but drinking excessive water does not disinfect an injured urethra or cure a significant infection. Similarly, cranberry products, supplements, antiseptics, or home remedies should not be relied upon to treat complications caused by instrumentation. A bacterial urinary infection may require appropriate testing and prescription treatment. Structural injury or stricture requires a different approach entirely. Matching treatment to the actual diagnosis is essential. Persistent symptoms should therefore be evaluated rather than masked with temporary remedies.
Sexual health and urinary health also overlap because infections and inflammation can involve nearby tissues. Unexplained urethral discharge, sores, pelvic pain, burning urination, or exposure concerns may warrant testing for sexually transmitted infections. Instrumentation while the urethra is already inflamed can increase irritation. People should avoid inserting devices through damaged or infected tissue. A clinician can determine whether symptoms are more consistent with a urinary infection, STI, mechanical injury, or another condition. Accurate diagnosis allows appropriate treatment and reduces unnecessary medication.
Above all, people should feel comfortable seeking medical help when something goes wrong. Urologists, emergency clinicians, nurses, and other healthcare professionals regularly encounter urinary foreign bodies, urethral injuries, and complications involving sexual practices. Their priority is preventing infection, restoring normal urinary function, and limiting long-term damage. Providing accurate information about the device, timing, symptoms, and any removal attempts can make treatment safer. Embarrassment should never outweigh the risk of permanent injury. Prompt care is particularly important when urination becomes difficult, bleeding is significant, or systemic symptoms develop.
Frequently Asked Questions About Sounding Sticks
What is a sounding stick?
A sounding stick usually refers to a urethral sound, a smooth rod-shaped instrument designed for insertion into the urethra. Medical versions may be used by trained professionals for specific urological procedures, while non-medical self-use carries risks including infection and injury.
Is urethral sounding dangerous?
It can be. Possible complications include pain, bleeding, urinary tract infection, urethral tears, false passages, strictures, retained objects, and urinary retention.
Can sounding cause a urinary tract infection?
Yes. Inserting an instrument can introduce bacteria into the urethra and urinary tract, especially when equipment, hands, or surrounding surfaces are contaminated.
When should I seek medical help after sounding?
Seek prompt medical care for significant bleeding, severe or worsening pain, fever, chills, inability to urinate, a retained object, or symptoms suggesting infection. Persistent changes in urine flow should also be assessed because they may indicate urethral injury or scarring.
Can a sounding stick treat a urethral stricture at home?
A suspected urethral stricture should not be self-treated with a sounding device. A urologist should first confirm the cause of urinary narrowing and determine whether dilation, endoscopic treatment, surgery, or another approach is appropriate.
