Comparing cheek (buccal) tissue versus penile skin grafts for repairing long anterior urethral strictures

Penile Skin Versus Buccal Mucosal Graft in Augmentation Urethroplasty for Long Anterior Urethral Stricture: A Prospective Randomized Study

Not applicable Interventional Tanta University · NCT07074717

This will test whether cheek (buccal) tissue or penile skin works better to repair long anterior urethral strictures in men who need urethroplasty.

What this trial studies

This interventional surgical comparison enrolls men with long segment anterior urethral strictures and compares dorsal onlay buccal mucosal graft (BMG) urethroplasty to penile skin graft (PSG) urethroplasty. Eligible patients typically have strictures longer than 1 cm with spongiofibrosis and prior failed dilation or DVIU, while those with lichen sclerosus, prior hypospadias repair, or previous failed urethroplasty are excluded. Surgeons perform substitution urethroplasty using the assigned graft type and patients are followed for functional outcomes, complications, and stricture recurrence. The goal is to determine which graft yields better urinary function and fewer complications in this setting.

Who should consider this trial

Good fit: Men with long segment anterior (bulbar) urethral strictures over 1 cm with spongiofibrosis who have failed prior urethral dilatation or DVIU and meet surgical fitness criteria are ideal candidates.

Not a fit: Patients with lichen sclerosus, a history of hypospadias repair, or recurrent stricture after previous urethroplasty are excluded and unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the results could help surgeons choose the graft that provides better long-term urinary function and fewer complications for men with long anterior urethral strictures.

How similar studies have performed: Both buccal mucosal grafting and penile skin reconstruction have extensive case-series support and good reported outcomes, but direct head-to-head comparative data are limited.
