Laparoscopic Assisted Ileal Ureter: Technique, Outcomes and Comparison to the Open Procedure

Purpose: Ureteral replacement with interposition of a bowel segment has traditionally required a large incision with substantial associated morbidity and prolonged time to convalescence. During the last 7 years a technique for laparoscopic assisted ileal interposition has evolved that mimics our open approach. We present a comparative analysis of functional and perioperative outcomes between patients undergoing laparoscopic or open ileal ureter replacement at our institution. Materials and Methods: A search of all procedures from 1980 to the present revealed 7 patients undergoing laparoscopic and 7 undergoing open ileal interposition. Functional and perioperative data from these patients are compared, and a detailed description of technique for the laparoscopic procedure is presented. Results: Narcotic analgesic use in morphine equivalents (median 38.9 vs 322.2 mg, p = 0.035) and time to convalescence (median 4 vs 5.5 weeks, p = 0.03) were significantly less in the laparoscopic group. A trend toward shorter hospital stay (median 5 vs 8 days, p = 0.101) was also noted in patients in the laparoscopic group. There was no evidence of anastomotic stricture for patients in either group at last followup. Conclusions: Despite the small number of subjects involved a significant advantage was noted for postoperative recovery after laparoscopic compared to open ileal interposition. A detailed understanding of this complicated procedure can help prevent inherent pitfalls.
