Endourethroplasty in the management of complicated posterior urethral strictures.

A 2-step endourethroplasty was performed to repair complicated posterior urethral strictures in 3 patients. In the first procedure scar tissue was resected transurethrally to create a smooth grafting bed. In a second endourological procedure a piece of full thickness prepuce was grafted at the stricture site. An intraluminal balloon catheter was used to keep the skin graft in close contact with the resected area of the urethra. Of the patients 2 have remained free of stricture for more than 22 months and 1 has remained free of stricture for more than 12 months after endourethroplasty. The technique offers a promising alternative to open surgery in selected patients with complicated posterior urethral strictures.
