Anastomotic urethroplasty, often called end-to-end urethroplasty, removes a short scarred urethral segment and reconnects healthy urethral ends without tension. It is commonly used for selected short bulbar strictures and is the standard reconstructive principle for many pelvic-fracture posterior urethral injuries. It is not suitable for every stricture: removing a long penile segment can shorten the urethra and cause curvature. The exact operation may be transecting or tissue-sparing depending on the stricture and surgeon’s approach.

What happens during anastomotic urethroplasty?

Through a perineal incision, the urethra is exposed. Dense scar is identified and, when appropriate, excised until healthy mucosa is reached. The two healthy ends are mobilised enough to meet without tension and are sutured together over a catheter.

Who is a good candidate?

• Very short bulbar stricture where excision will not create excessive tension.
• Short traumatic bulbar scar with dense spongiofibrosis.
• Pelvic fracture urethral distraction injury requiring posterior anastomosis.
• Selected short recurrent anastomotic narrowing depending on anatomy.

When is it not ideal?

• Long anterior strictures where excision would require excessive mobilisation.
• Most penile strictures, because shortening can cause chordee/curvature.
• Lichen sclerosus with long diseased urethral tissue.
• Situations where preserving urethral blood supply/tissue is preferred and an augmentation repair is more suitable.

Transecting versus non-transecting concepts

Traditional excision-and-primary-anastomosis divides the urethra completely and removes the scar. Modern bulbar reconstruction also includes non-transecting techniques that preserve more corpus spongiosum and vascular continuity when the scar pattern allows. The best choice depends on whether the scar is mucosal, dense and obliterative, traumatic or recurrent.

How is posterior anastomotic repair different?

In pelvic fracture urethral injury, the scarred gap lies near the membranous urethra and prostate. The reconstruction often requires removal of all scar and progressive manoeuvres to bring the bulbar urethra to the proximal urethral stump. This is a specialised posterior urethroplasty rather than a simple short bulbar repair.

Benefits

• No graft donor site in suitable short strictures.
• High durable patency in appropriately selected anatomy.
• Complete removal of dense focal scar.

Risks and functional considerations

• Recurrent narrowing at the anastomosis.
• Bleeding, infection or urine leak.
• Temporary perineal numbness or pain.
• Post-void dribbling.
• Temporary erectile changes in some men.
• Penile shortening or curvature if excessive anterior urethral length is sacrificed.

Catheter and recovery

A urethral catheter is left while the anastomosis heals. Duration varies by repair; many anterior urethroplasties use roughly two to three weeks, while selected uncomplicated anastomotic repairs may be assessed earlier. Urethrography is commonly performed before catheter removal to check for leakage.

What determines success?

Success depends on removing or adequately opening scar, achieving a tension-free well-vascularised join and choosing the technique for the correct length/location. Radiation, multiple previous operations and associated fistulae make reconstruction more complex.

A practical recovery timeline

• First days: catheter drainage, perineal wound care and gentle walking. Bruising and discomfort with sitting are common.
• First few weeks: avoid cycling, motorbike riding, heavy lifting and sexual activity until the operating surgeon clears them. Keep the catheter secured so it does not pull on the repair.
• Catheter removal: timing depends on the repair and healing; some surgeons obtain a urethrogram first. A small leak may simply require additional catheter drainage.
• Following months: uroflowmetry and symptoms establish whether the anastomosis remains open. New straining, slowing stream, recurrent UTI or retention should be assessed rather than self-dilated.

What to bring for consultation

• RGU and MCU/VCUG images or films, not only the written report.
• Uroflowmetry report and post-void residual if already done.
• Urine routine and urine culture reports.
• Serum creatinine and other relevant blood tests.
• Previous catheter, VIU/dilatation or urethroplasty discharge summaries.
• Details of any pelvic injury, prostate surgery, hypospadias surgery, radiation or recurrent infections.
• Current medicines, including blood thinners, and any history of self-dilatation.

When end-to-end repair is – and is not – a good idea

Anastomotic urethroplasty works best when the diseased segment can be removed and the healthy ends can meet without harmful tension. That is most often possible for selected short bulbar strictures and for posterior distraction injuries, where the operation and anatomy are different. The surgeon may use a transecting excision-and-primary-anastomosis technique or a non-transecting anastomotic approach depending on the scar and spongiosum.

The word “short” cannot be reduced to one universal centimetre number because urethral elasticity, stricture position, prior surgery and the amount of healthy tissue matter. In penile urethral strictures, excision and anastomosis is generally avoided except in very selected extremely short injury-related disease; shortening the penile urethra can produce chordee/curvature.

If a bulbar stricture is too long for a tension-free anastomosis, graft augmentation is usually safer than forcing the ends together. A good reconstructive result is therefore not defined by using the smallest amount of graft – it is defined by achieving durable calibre without creating avoidable shortening, curvature or sexual morbidity.

How the urethra is joined without tension

Through a perineal incision, the surgeon exposes the bulbar urethra and identifies the limits of dense fibrosis. In a classic excision-and-primary-anastomosis repair, the scarred segment is removed until healthy mucosa and spongiosum are reached. The two ends are spatulated so the new opening is broad rather than a narrow circular join, then sutured mucosa-to-mucosa over a catheter.

The critical principle is not simply removing scar; it is obtaining that join without excessive tension. The bulbar urethra has useful mobility, but only to a point. If the gap is too long, forcing the ends together can shorten or angulate the urethra and compromise blood supply. A graft augmentation is then more appropriate.

Non-transecting anastomotic techniques preserve more of the surrounding spongiosum in selected short non-obliterative strictures, while a completely obliterated traumatic segment may require full excision. The term “end-to-end” therefore describes a family of reconstructive principles rather than one identical operation for every patient.

Recovery and follow-up after anastomotic urethroplasty

A urethral catheter remains across the anastomosis while the two mucosal ends heal. The duration varies with location and complexity; a urethrogram may be used before removal. Perineal bruising, temporary numbness and discomfort with prolonged sitting are common early issues after bulbar surgery.

Patients often worry about penile shortening or erectile dysfunction. A properly selected short bulbar anastomosis is not intended to shorten the penis externally, but extensive urethral excision under tension can affect geometry, which is why longer penile strictures are not treated this way. Temporary erectile change can occur after anterior urethroplasty; persistent dysfunction is uncommon but should be assessed if it occurs.

Follow-up establishes a postoperative flow baseline and checks for early narrowing. Anastomotic recurrences are often focal; a selected very short diaphragm-like recurrence may be amenable to endoscopic treatment, while a dense recurrent scar needs redo reconstructive assessment.
