Joshi's Step With Buccal Mucosal Graft Urethroplasty in Nearly Obliterated Bulbar Urethral Stricture: A Prospective Study

Not applicable Interventional Tanta University · NCT07088198

What this trial studies

This single-center interventional program applies a non-resecting modification (Joshi's step) to augmented buccal mucosal graft urethroplasty for very narrow bulbar strictures. The technique marks the narrowest segment without excising the native urethral plate and reapproximates mucosal edges before graft augmentation. Eligible patients are those with primary, non‑traumatic, nearly obliterated bulbar strictures under 1.5 cm in length, and outcomes will focus on functional urinary results and surgical success. Patients with traumatic, redo, fully obliterated, or long segment strictures are excluded.

Who should consider this trial

Good fit: Adults with primary, non‑traumatic nearly obliterated bulbar urethral strictures where the narrowest portion is less than 1.5 cm and who have not had prior urethroplasty are ideal candidates.

Not a fit: Patients with traumatic, redo, fully obliterated, or long-segment bulbar strictures are excluded and are unlikely to benefit from this specific technique.

Why it matters

Potential benefit: If successful, the approach could improve urine flow and surgical success while preserving more of the native urethra compared with resectional repairs.

How similar studies have performed: This non-resecting modification (Joshi's step) was described in 2022 and remains a relatively new technique with limited published outcome data to date.
