Objective: To present long-term results of our laparoscopic intracorporeal ileal ureter replacement (LIUR) cohort, including more complex cases of laparoscopic ileocalycostomy. Material and methods: We collected records of patients undergoing LIUR. Follow-up included a chemical profile and urine cultures. Imaging consisted of renal ultrasonography, excretory urography, cystography, and computer tomographic or magnetic resonance urography. Results: One hundred and two patients were included. Stricture location was left (46.1%), right (39.2%), or bilateral (14.7%). No open conversion was performed. Seventy-four patients (72.5%) underwent a total ureteral unit removal. The mean operative time was 289.4 (120 - 680) minutes. The estimated blood loss was 185.2 (10-400) mL. Three patients had intraoperative complications, and fifteen had early postoperative complications. The mean postoperative hospital stay was 12.2 (7-35) days. The mean follow-up duration period was 37.7 (12-162) months. Most patients' follow-up was uneventful (88%), and seven patients presented with Grade 2 late complications. Conclusions: Intracorporeal laparoscopic ileal ureteral replacement in cases of extensive ureteral lesions offers optimal long-term outcomes and a low complication rate. Ileocalycostomy constitutes a viable option in the small group of patients with long proximal ureteral strictures and intrarenal pelvis.
