Distal ureteral replacement with tubularized porcine small intestine submucosa.

Extensive ureteral injury can result from renal stone disease, iatrogenic injury, or penetrating trauma. A significant ureteral stricture can be repaired using various techniques, including the psoas hitch, Boari flap, transureteroureterostomy, ileal ureter, or renal autotransplantation. We describe a woman with a 5-cm, ischemic uretero-Indiana pouch stricture that developed after cystectomy and urinary diversion. Severe pelvic fibrosis prevented adequate mobilization of the ureter and Indiana pouch and would not permit any of the above-mentioned procedures. We report the first human use of tubularized small intestine submucosa to successfully replace a 5-cm strictured segment of distal ureter.
