Objective: To prove the feasibility, as well as the reproducibility of laparoscopic totally intracorporeal ileal ureter replacement (LIUR), by presenting a multicenter patient cohort with a long follow-up.
Material and methods: Records of patients undergoing different types of ureteral replacements have been collected. Follow-up included a chemical profile and urine cultures. Imaging consisted of renal ultrasonography and excretory urography, as well as a cystography or an isotopic renography when indicated.
Results: Forty patients were included in the study. Twelve underwent a right, 20 a left, and eight a bilateral laparoscopic ureteral replacement. The mean procedure time was 335 (150-680) minutes and the mean estimated blood loss was 221 (50-400) mL. Only three patients presented intraoperative complications, which were managed immediately, and three patients presented a Clavien III postoperative complication. Abdominal drains and nephrostomy tubes were removed after 24-36 h and 7-10 days, respectively. The mean hospital stay was 13.5 (10-35) days. Follow-up was at least six months.
Conclusions: LIUR constitutes a feasible and reproducible method for the restoration of long ureteral defects.
