Perineum-based Pediculated Scrotal Flap for Reconstructive Urethral Surgery

Abstract

Herein, we describe a perineum-based pediculated scrotal flap procedure for urethral reconstruction. A scrotal tubular flap was used as a substitute to correct a proximal penile urethral stricture in case 1. In case 2, a scrotal island patch was performed to treat an iatrogenic penile urethral injury. In both cases, the urethral catheter was removed on postoperative day 14 with simultaneous normal voiding cystourethrography. The excellent axial vascularization of this perineum-based pediculated scrotal flap procedure allows successful urethral reconstruction, regardless of extension, location, and etiology.

Practice of the use of oral mucosa graft urethroplasty among Nigerian urologists

“…15 For the treatment of more complex strictures in which end-to-end anastomotic urethral reconstruction is not possible or may result in poor cosmetic and functional outcomes, a number of substitute tissues have been employed such as scrotal skin flaps, various modifications of penile island fascio-cutaneous flaps and extra-genital grafts from the bladder mucosa, colonic mucosa, tunica albuginea, tunica vaginalis and saphenous vein graft. [16][17][18][19][20][21][22] In the last three decades, there has been a resurgence in the use of extragenital grafts and oral mucosa grafts (OMGs) have been gaining increasing application and acceptability as suitable urethral substitute tissue for repair of complex strictures either as single or multi-staged urethral reconstructions. 23,24 Oral mucosa refers to the mucosal lining of the oral cavity and consists of: buccal (over the cheek); labial (the lip); and lingual (the lateral and under-surface of the tongue).…”
