Laparoscopic nephrectomy with mini-incision kidney auto- transplantation in severe ureteral strictures: report of three cases and review of the literature

Severe and long ureteral injuries are difficult to be managed. In presence of a complex injury of the upper ureter, nephrectomy, bowel interposition, and kidney autotransplantation (KAT) are usually proposed. Kidney autotransplantation (KAT) represents a complex surgical procedure with a high risk of complications that could preserve renal function. We update our experience with renal autotransplantation for severe iatrogenic ureteral injuries. Three patients with complex ureteral injuries were referred for definitive management by KAT. Transperitoneal laparoscopic nephrectomy (LN) and open mini-incision KAT (mKAT) to the ipsilateral pelvis were attempted. After bench preparation of the graft, ureteral and vessel length and quality was adequate for autotransplantation in all cases. There were no intra- and postoperative complications and all grafts functioned immediately and at medium-term follow-up of 6 months. KAT gives excellent post-operative results without significant deterioration in renal function at medium-term follow-up. It represents a safe alternative method for the management of complex ureteric strictures when conventional surgical techniques have failed or are not suitable. Intensive collaboration with all transplant teams is crucial to ensure the high quality of the graft and to improve surgical and functional outcomes.
