Two stage scrotal flap urethroplasty.

This technique is derived from the Denis Browne two-stage technique for hypospadias. It was developed by Johanson and perfected by Turner-Warwick. It uses an invaginated flap of scrotal skin sutured to the edges of the exposed stenotic urethra. The second stage (2 to 3 months later) closes the urethra in two layers. No statistics are available for the results obtained.
