AB192. Retroperitoneal laparoscopic ureteroplasty for retrocaval ureter—report of two cases

OBJECTIVE: To investigate the effect of retroperitoneal laparoscopic ureteroplasty for retrocaval ureter. METHODS: Retrospectively analysis of clinical data about two cases with retrocaval ureter treated by retroperitoneal laparoscopic ureteroplasty. Both of two cases were the renal pelvis and ureter were dissociated up to the retrocaval, and then segregated the adherence between ureter and inferior vena cave. Excised retrocaval segment, detained one double J tube and took end to end anastomosis. Established the normal anatomy. RESULTS: The two ureteroplasty were accomplished successfully by retroperitoneal laparoscopic, no conversion to open surgery. Operative time was 77 and 139 min respectively. Hemorrhage less than 50 mL during operation, no blood transfusion, urinary leakage do not occurred postoperative. Remove the double J tube after 6 weeks. Follow-up of 6 months, one case of discomfort symptoms complained lumbago lost, ultrasound hydronephrosis no aggravating. CONCLUSIONS: Retroperitoneal laparoscopic ureteroplasty for retrocaval ureter is safe and effective, with less trauma, less hemorrhage, little postoperative pain, effective and reliable, can be used as the preferred treatment for retrocaval ureter.
