With the minimal morbidity attained using laparoscopy, its application in urologic surgery has been increasing. Using laparoscopic techniques we successfully completed the transposition and re-anastomosis of a retrocaval right ureter. Operation time was 240 minutes. The patient was allowed to walk on the first post-operative day and resumed oral intake on the second day. Administration of analgesics was not required. The ureteral stent was removed on the 24th day after operation. An intravenous urogram three months after operation showed a decrease in hydronephrosis. Laparoscopic correction of retrocaval ureter by extraperitoneal approach is a safe, feasible technique, avoiding a large surgical wound with the definite advantage of minimal disfigurement. Operating time is considerably shorter compared to the peritoneal approach as described by Baba (240’ vs 560’).
