We report the use of Porcine Intestinal Submucosa (PIS) in association with Johanson technique for urethroplasty, in the treatment of recurring urethral stenosis. The patient had obliterans xerotica balanitis and had previously undergone 15 internal uretotomies as well as various unsuccessful urethral dilations. As a result of stenotic extension, another surgery was planned using Johanson technique. During the first part of the surgery, intense local fibrosis was observed, which required greater care and protection to avoid fistulae formation. PIS was interposed to reduce the chances of the occurrence of this dreaded complication. During the second part of the surgery, a skin flap obtained from tissue parallel to the urethral plateau was used to prepare a neourethra according to the norms of this technique. PIS was fixed at its extremities, and interposed between the neourethral suture and the skin suture to prevent any contact between them. The procedure was completed with the use of meatoplasty and glandulaplasty. After 6-month follow up, clinical and urodynamic improvement could be seen. If these results can be confirmed by more extensive studies, PIS will provide new perspectives for complex urethroplasties.
