Retroperitoneoscopic transureteroureterostomy with cutaneous ureterostomy to salvage failed ileal conduit urinary diversion.

Reconstruction for failed urinary diversion is technically challenging, due to severe tissue adhesion around the anastomotic site. We report successful laparoscopic transureteroureterostomy with cutaneous ureterostomy via a completely extraperitoneal approach to salvage failed ileal conduit in two patients with necrotic ileal conduit and bilateral anastomotic obstruction, respectively. This novel, less invasive approach may offer a viable alternative to open surgical revision for failed ileal conduit urinary diversion.
