Case in brief
A 65-year-old man developed a penile urethral stricture after urethral instrumentation and prolonged catheterization following radical prostatectomy. Cystourethrography showed a 1.2 cm stricture. He underwent urethroplasty with a free aldehyde-free bovine pericardium graft placed as a dorsal onlay. No perioperative complications were reported. At seven weeks, urethroscopy showed a patent-appearing lumen, with the graft incorporated and no infection or adverse tissue reaction. Voiding parameters were satisfactory, with low post-void residual urine.
What made this case unusual
The case describes penile urethral reconstruction using an aldehyde-free bovine pericardium graft, with early endoscopic assessment showing graft incorporation and urethral patency.
Diagnostic / clinical pearl
For a penile urethral stricture after instrumentation, cystourethrography can define the lesion; this report illustrates graft urethroplasty as an option when reconstruction without grafting may risk penile shortening or functional compromise.
Why it matters
The favorable early findings support feasibility in this case, but the report notes that larger studies are needed to establish longer-term efficacy and safety.
