Urethroplasty

Introduction

If you have been diagnosed with a urethral stricture and your urologist has discussed surgery, you are likely weighing what urethroplasty involves, how it differs from other treatments you may have tried, and what recovery looks like. This guide is written for that moment — after the diagnosis, before or shortly after the operation, when the practical questions matter most.

Urethroplasty is a reconstructive operation that repairs or rebuilds the narrowed part of the urethra. It is the most durable treatment available for many types of urethral stricture, particularly longer strictures or those that have come back after simpler procedures. Outcomes are generally good in experienced hands, but recovery requires patience, a period with a urinary catheter, and structured follow-up.

The sections below explain what the surgery is, who is considered a candidate, how it compares with alternatives such as dilation and internal urethrotomy, the main surgical approaches your surgeon may discuss, what happens before, during, and after the operation, and what to expect in the months and years that follow.

What Is Urethroplasty?

The urethra is the tube that carries urine from the bladder to the outside of the body. In men, it passes through the prostate and along the penis; in women it is much shorter. A urethral stricture is a section of this tube that has narrowed because of scar tissue. The narrowing makes it harder for urine to flow, which over time can affect the bladder and, in severe cases, the kidneys.

Urethroplasty is open reconstructive surgery to repair this narrowed segment. Depending on the length, location, and cause of the stricture, the surgeon may remove the scarred portion and rejoin the healthy ends, or widen the urethra using a tissue graft — most often a small piece of lining from inside the cheek (buccal mucosa). The aim is a lasting repair rather than a temporary opening of the narrowed channel.

Urethroplasty is performed almost entirely in men, because urethral stricture disease is much more common in male anatomy. Female urethral stricture is rare and managed with different techniques when it does occur.

Major urology bodies, including the American Urological Association (AUA) and the European Association of Urology (EAU), describe urethroplasty as the most durable option for adult male urethral stricture, particularly for longer or recurrent strictures.

Why Is Urethroplasty Performed?

Urethroplasty is performed to relieve the obstruction caused by a stricture and to restore normal urine flow. Doctors typically consider it when:

• The stricture is longer than about 2 centimetres
• The stricture has come back after one or more previous endoscopic treatments
• The stricture is in a location (such as the penile urethra or posterior urethra after pelvic injury) where simpler procedures are unlikely to work
• The patient is otherwise fit for open surgery and prefers a definitive repair over repeated procedures

The symptoms that lead to a stricture diagnosis — and which urethroplasty is intended to address — usually include some combination of the following:

• A weak or slow urinary stream
• Difficulty starting urination
• Straining to pass urine
• Spraying or splitting of the stream
• A feeling that the bladder is not fully empty
• Dribbling after urination
• Recurrent urinary tract infections
• Episodes of being unable to pass urine at all (acute urinary retention)

Left untreated, severe strictures can cause the bladder muscle to thicken or weaken, lead to repeated infections, and in rare cases damage the kidneys. Restoring flow protects the rest of the urinary system as well as relieving symptoms.

Who Is a Candidate?

Whether urethroplasty is the right choice in your situation is a clinical decision made with your urologist, but several factors generally support it:

• Stricture length and location: Bulbar strictures (in the part of the urethra inside the perineum) and penile strictures are common sites for urethroplasty. Posterior urethral injuries after pelvic fracture also typically require open reconstruction.
• Failure of less invasive treatment: If dilation or internal urethrotomy has been tried and the stricture has returned, current AUA and EAU guidance favours moving to urethroplasty rather than repeating endoscopic procedures.
• General fitness: The surgery requires general or regional anaesthesia and a period of recovery, so overall health, heart and lung function, and the ability to heal are considered.
• Realistic expectations: Patients who understand the catheter period, the recovery timeline, and the small but real risks of complications tend to do better.

Some situations make surgery more complex, including very long strictures, multiple previous failed repairs, heavy scarring from radiation, active infection, and poorly controlled diabetes. These do not necessarily rule out urethroplasty but may change the technique used or the timing.

Alternatives to Urethroplasty

Before urethroplasty, most patients have tried or considered one or more of the following. Understanding how they compare helps frame the decision.

Urethral Dilation

The narrowed segment is gradually stretched using progressively larger instruments. It is the simplest option and can be done in clinic. Symptom relief is often immediate but tends to be short-lived — the scar tissue typically re-narrows. Repeated dilations can be useful as a holding measure but generally do not cure the stricture.

Direct Vision Internal Urethrotomy (DVIU)

An endoscope is passed into the urethra and a small blade or laser is used to cut the scar tissue, opening the channel. DVIU works best for short (under about 1.5–2 cm), single, previously untreated bulbar strictures. Long-term success after a first DVIU is modest, and success rates fall sharply if it is repeated for a stricture that has already come back.

Repeated Endoscopic Treatment

Some patients choose ongoing dilation or DVIU to manage symptoms rather than undergo open surgery. AUA guidance notes that this can be reasonable in selected cases but does not address the underlying scar.

Self-Catheterisation

In some cases, a patient is taught to pass a small catheter through the urethra periodically to keep the channel open. This is a maintenance strategy, not a repair.

Permanent Urinary Diversion

In rare, very complex cases where reconstruction is not possible, the urinary tract may be rerouted — for example through a suprapubic catheter (a tube into the bladder through the lower abdomen) or a surgically created opening. This is reserved for situations where reconstruction has failed or is not feasible.

Compared with these options, urethroplasty offers the most durable result for moderate, long, or recurrent strictures — which is why it is described in major guidelines as the reference treatment for these patterns. The trade-off is a more involved surgery and a longer initial recovery.

Surgical Approaches

Excision and Primary Anastomosis (EPA)

The scarred segment is cut out completely and the two healthy ends of the urethra are stitched directly together. EPA is typically used for short bulbar strictures (usually under about 2 cm) and for posterior urethral injuries after pelvic fracture. Long-term success rates are high in published series because no graft tissue is needed and the repair uses the patient’s own healthy urethra.

Buccal Mucosal Graft Urethroplasty

For longer strictures, removing the entire scarred segment would shorten the urethra too much. Instead, the surgeon opens the narrowed segment and patches it with a graft. The most common graft is buccal mucosa — the moist lining from inside the cheek — because it is thin, hairless, accustomed to a wet environment, and heals well.

The graft may be placed on the top (dorsal), bottom (ventral), or side of the opened urethra depending on the technique. Buccal mucosal graft urethroplasty is widely used for bulbar and penile strictures and has good long-term outcomes in experienced centres.

Skin Flap Urethroplasty

In selected cases, particularly long penile strictures, a flap of nearby skin (such as from the foreskin or shaft skin) is rotated into position to reconstruct the urethra. Flaps bring their own blood supply, which can be useful in tissue that has been previously operated on or irradiated.

Staged Urethroplasty

When the stricture is very long, the scarring is severe, or previous repairs have failed, the reconstruction may be done in two stages, several months apart. In the first stage, the urethra is opened and a graft is laid in to mature. In the second stage, the new urethra is tubularised — rolled into a tube and closed. Staged repairs are reserved for complex cases but allow reconstruction where a single-stage approach would not succeed.

Robotic-Assisted Urethroplasty

For certain posterior urethral and bladder-neck reconstructions, a robotic abdominal approach is used in selected advanced centres. This is a small subset of urethroplasty cases. For most bulbar and penile strictures, open perineal or penile surgery remains the standard approach — minimally invasive endoscopic techniques are not a substitute for reconstruction once a true stricture has formed.

Preparing for Urethroplasty

Preparation usually begins several weeks before surgery and includes both medical assessment and practical planning.

Diagnostic Mapping of the Stricture

Accurate measurement of the stricture is essential. The main tests used are:

• Retrograde urethrogram (RUG) and voiding cystourethrogram (VCUG): X-ray studies in which dye is passed through the urethra and bladder to show the length and location of the narrowing.
• Cystoscopy: A thin camera is passed into the urethra to view the stricture directly.
• Uroflowmetry: Measures the strength of the urine stream.
• Post-void residual ultrasound: Checks how much urine is left in the bladder after passing urine.
• Ultrasound of the kidneys and bladder: Looks for any back-pressure effect on the upper urinary tract.

General Health Assessment

Blood tests, urine cultures (to confirm no active infection), an ECG, and a review of any long-term conditions such as diabetes are standard. Active urinary infection is treated before surgery.

Lifestyle Steps

Smoking significantly impairs wound healing and graft uptake. Doctors typically advise stopping smoking for at least several weeks before and after surgery. Good blood sugar control is important for those with diabetes. Some medications — particularly blood thinners — may need to be paused on the surgeon’s advice.

Practical Planning

Patients are usually advised to plan for a hospital stay of a few days, a period at home with a urinary catheter, and several weeks of reduced activity before returning to a normal routine. Arranging help for the first week at home is sensible.

What Happens During Urethroplasty

Urethroplasty is performed under general or regional anaesthesia. The surgery typically takes between two and four hours, depending on the technique and complexity.

For most bulbar and penile strictures, the surgeon makes an incision in the perineum (the area between the scrotum and anus) or along the underside of the penis to reach the affected segment of the urethra. The narrowed section is identified and assessed directly.

From this point, the steps depend on the planned technique:

• In excision and primary anastomosis, the scarred segment is cut out and the healthy ends are stitched together.
• In a graft procedure, the narrowed segment is opened along its length and the graft — usually buccal mucosa harvested from inside the cheek through a separate, small incision in the mouth — is stitched into place to widen the channel.
• In a flap procedure, nearby tissue with its own blood supply is rotated into position.
• In a staged procedure, only the first stage is performed; the second stage follows months later.

A urinary catheter is then placed through the urethra and into the bladder to divert urine away from the repair while it heals. The incisions are closed in layers. If buccal mucosa was harvested, the mouth wound is also closed and usually heals quickly.

Most patients wake up in the recovery area with the catheter in place and mild to moderate discomfort that is managed with pain relief.

Recovery and Healing

Hospital Stay

Most patients stay in hospital for a short period — often two to five days — depending on the complexity of the surgery and how quickly pain and mobility allow safe discharge.

The Catheter Period

The catheter usually stays in place for about two to three weeks after surgery, sometimes longer for complex repairs. During this time:

• Drink plenty of fluids to keep urine dilute
• Keep the catheter and entry point clean as instructed
• Avoid pulling on the catheter or letting it kink
• Avoid heavy lifting, straining, and vigorous activity

Before the catheter is removed, a pericatheter retrograde urethrogram or similar study is often performed: dye is injected around the catheter to confirm the repair has sealed and there is no leak. If the study is normal, the catheter is removed.

If Buccal Mucosa Was Used

The mouth is usually sore for a few days. A soft diet, gentle saltwater rinses, and avoiding spicy or very hot foods helps healing. The cheek lining typically regenerates within a couple of weeks.

Activity Timeline

• Weeks 1–2: Rest at home; light walking; no lifting, cycling, or straining.
• Weeks 3–4: After catheter removal, gradual return to most daily activities; continue to avoid heavy exertion.
• Weeks 4–6: Most patients are back to a normal routine, including desk work.
• Sexual activity: Generally resumed after about six weeks, once the surgeon confirms healing.

Some patients notice a stronger stream almost immediately after catheter removal; for others it improves over weeks as swelling settles.

Risks and Complications

Urethroplasty is generally safe when performed by experienced reconstructive urologists, but no surgery is risk-free. Possible complications include:

• Wound infection or haematoma at the perineal or penile incision
• Urinary tract infection during the catheter period
• Bleeding, usually minor
• Stricture recurrence — the most important long-term concern; recurrence rates are low for short bulbar repairs and somewhat higher for long, penile, or repeat repairs
• Urinary fistula — an abnormal channel between the urethra and the skin or other tissue, sometimes needing further surgery
• Sexual side effects, including temporary changes in erection or ejaculation; persistent erectile dysfunction is uncommon after standard bulbar urethroplasty but is a recognised, infrequent complication
• Urinary incontinence — rare after most urethroplasties but a recognised risk after posterior urethral reconstruction
• Penile changes such as shortening or curvature in selected procedures involving the penile urethra
• Mouth-related effects from buccal graft harvest, usually minor and short-lived
• General surgical risks: anaesthetic reactions, blood clots, chest complications

The risk profile varies with the technique used and the complexity of the stricture. Your surgeon will discuss the risks most relevant to your specific operation.

Life After Urethroplasty

Most patients notice a clear improvement in urinary symptoms after recovery: a stronger stream, easier starting, more complete emptying, and fewer infections. Published long-term success rates from specialist reconstructive units are high, particularly for short bulbar repairs, and remain good for longer and graft repairs in experienced hands.

Follow-Up

Follow-up is essential because strictures can recur silently — sometimes years later — before symptoms return. Typical follow-up may include:

• Clinic review at intervals during the first year
• Uroflowmetry to track stream strength
• Post-void residual ultrasound
• Cystoscopy or urethrogram if symptoms suggest recurrence

Habits That Support Long-Term Results

• Stay well hydrated
• Avoid smoking
• Manage diabetes carefully if relevant
• Treat urinary infections promptly
• Report any return of weak stream, straining, or recurrent infections early, rather than waiting for severe symptoms

Sexual Function

Most men return to their baseline sexual function after recovery. Some notice transient changes in erections or ejaculation that settle over a few months. If sexual symptoms persist, they should be raised at follow-up — they are a recognised topic in reconstructive urology and can be addressed.

If the Stricture Recurs

If a stricture does recur, treatment depends on its length and location. Options include endoscopic management for very short recurrences or a further reconstructive procedure for longer ones. A recurrence does not mean reconstruction has “failed” in any final sense — it means a new clinical decision is needed.

Urethroplasty in Children

Urethroplasty in children is a different field from adult stricture surgery and is performed by paediatric urologists. The most common indication is hypospadias repair — a congenital condition in which the urethral opening is not at the tip of the penis — rather than acquired stricture disease. Posterior urethral injuries after pelvic trauma are another paediatric indication.

Techniques in children share the general principles of reconstruction (excision, grafting, flaps, sometimes staged repair) but are tailored to the child’s anatomy and developmental stage. Recovery is typically faster in children, but follow-up extends through growth into adolescence, because the reconstructed urethra needs to perform well as the child grows. Parents of children with congenital urethral conditions are usually under the care of a paediatric urology team that follows the child long-term.

Frequently Asked Questions

Is urethroplasty a permanent solution?

In published series, urethroplasty has the highest long-term success of the available treatments for urethral stricture. Many patients have a single repair that lasts for the rest of their lives. Recurrence is possible, particularly with longer or more complex strictures, which is why follow-up matters.

Why is urethroplasty preferred over repeated dilation or DVIU for longer strictures?

Dilation and DVIU open the channel but do not remove or replace the scar. For short, first-time bulbar strictures they can work; for longer or recurrent strictures, repeated endoscopic procedures have diminishing success. AUA and EAU guidance favour moving to reconstruction in these situations rather than continuing to repeat short-term treatments.

How long will I need a urinary catheter after surgery?

Usually about two to three weeks, sometimes longer for complex repairs. The exact duration is decided by your surgeon based on the technique used and how the repair is healing.

Will urethroplasty affect my sexual function?

Most men return to their baseline sexual function. Temporary changes in erection or ejaculation are common in the early weeks. Persistent sexual side effects are uncommon after standard bulbar repair but are a recognised, small risk and worth discussing with your surgeon beforehand.

How soon can I return to work?

Many patients return to desk-based work around four weeks after surgery. Physically demanding work usually requires longer — often six weeks or more. Your surgeon will give specific guidance based on your operation.

What happens if the stricture comes back?

A short, late recurrence may be managed endoscopically; a longer recurrence may need a further reconstructive procedure. Either way, it is a new decision rather than an end-point.

Is buccal mucosa — tissue from inside the cheek — really suitable for the urethra?

Yes. Buccal mucosa is thin, hairless, used to a wet environment, and heals well. It has been used in urethral reconstruction for decades and is the most commonly used graft material worldwide.

Conclusion

Urethroplasty is reconstructive surgery designed to provide a lasting repair of a narrowed urethra. For many patients with longer, recurrent, or complex strictures, it offers the most durable improvement in urinary function available, and major urology bodies describe it as the reference treatment in these situations. The trade-off is a more involved surgery, a few weeks with a catheter, and a recovery measured in weeks rather than days.

The right surgical approach — excision and primary anastomosis, a buccal mucosal graft, a flap, a staged repair, or, in selected cases, a robotic approach — depends on the specifics of your stricture and is a decision made with your reconstructive urologist. With careful planning, experienced surgery, and consistent follow-up, most patients return to a normal urinary pattern and a normal daily life.
