The definitive surgical correction for urethral strictures. This includes Excision and Primary Anastomosis (EPA) for short-segment scarring, and Buccal Mucosa Grafting (BMG) utilizing tissue transfer from the inner cheek for complex, long-segment reconstructions to restore a durable, open channel.

Clinical Indication

This procedure is highly indicated for patients experiencing structural anomalies, severe localized scar tissue, or functional blockages that fail to resolve with initial conservative therapeutic adjustments.

Surgical Objective

The principal objective is the complete restoration of physiological form, functional urinary path independence, or mechanical integrity, maximizing long-term outcomes while minimizing systemic downtime.

Definitive Urethroplasty & Clinical Principles

Urethroplasty offers the most durable long-term results for urethral strictures.

Urethroplasty represents the established gold-standard definitive surgical treatment for urethral stricture disease of the anterior and posterior urethra. While repetitive endoscopic procedures (such as serial urethral dilation or visual internal urethrotomy [DVIU]) are likely to fail again once a stricture has come back, while open urethroplasty offers far more durable results. The surgical approach is individualized based on stricture location (bulbar, penile, membranous), stricture length, caliber, and the health of the surrounding corpus spongiosum.

Clinical Indications & Patient Selection

Reconstructive urethroplasty is indicated when luminal narrowing produces significant lower urinary tract symptoms, recurrent urinary tract infections, urinary retention, or secondary upper tract compromise.

Recurrent Bulbar Strictures: Strictures recurring after a prior dilation or DVIU, where repeat endoscopic manipulation provides diminishing returns.

Complex Long-Segment Narrowing: Strictures greater than 1.5–2 cm, pan-urethral strictures, or strictures secondary to Lichen Sclerosus (BXO) requiring tissue substitution.

Failed Endoscopic Balloon Dilations: Recurrent strictures following prior drug-coated balloon (Optilume®) therapy where definitive open excision or grafting is required.

Surgical Technique & Procedural Nuance

Surgery is performed via a midline perineal incision with vessel-sparing dissection to preserve dual bulbourethral blood supply and avoid erectile or ejaculatory disturbance.

Excision and Primary Anastomosis (EPA): Indicated for short (<1.5–2 cm) bulbar strictures. The scarred segment is completely excised, the proximal and distal healthy urethral ends are spatulated, and a tension-free direct mucosal-to-mucosal anastomosis is created over a 16Fr silicone catheter using 4-0 or 5-0 absorbable sutures.

Buccal Mucosa Graft (BMG) Augmentation: Indicated for longer bulbar or penile strictures. Non-keratinized oral mucosa is harvested from the inner cheek, defatted under high magnification, and quilted onto the tunica albuginea (dorsal onlay / Barbagli technique) or spongiosum (ventral onlay) to widen the urethral plate without shortening.

Two-Stage / Pan-Urethral Repair: For catastrophic lichen sclerosus or prior hypospadias failures, a staged reconstruction is performed with complete substitution of the urethral plate.

Postoperative Pathway & Recovery Timeline

Most urethroplasties are performed as outpatient ambulatory procedures or require an overnight observational stay.

Catheter Management: A 16Fr soft silicone urethral catheter remains in place for 10 to 14 days to stent the anastomosis/graft while mucosalization occurs.

Pericatheter Retrograde Urethrogram (RUG): Performed in the office prior to catheter removal to confirm watertight healing with zero extravasation.

Activity Restrictions: Heavy lifting (>15 lbs), strenuous exercise, and straddle activities (bicycling) are restricted for 3 to 4 weeks.

Outcomes, Durability & Clinical Evidence

Long-term data demonstrate excellent functional and anatomical outcomes across all validated clinical registries.

Durable Patency Rate: Most men remain free of recurrence long term in published reconstructive series.

Sexual & Ejaculatory Preservation: Vessel-sparing, non-transecting approaches preserve bulbospongiosus nerve branches, preserving baseline erectile function and preventing post-void dribbling.
