Abstract
CONTEXT AND AIM: Retrocaval ureter (RCU), also known as circumcaval ureter, occurs due to anomalous development of inferior vena cava (IVC) and not ureter. The surgical approach for this entity has shifted from open to laparoscopic and robotic surgery. This is a relatively new line of management with very few case reports. Herein, we describe the etiopathology, our experience with six cases of transperitoneal laparoscopic repair of RCU operated at tertiary care center in India and have reviewed different management options. METHODS: From 2013 to 2016, we operated total six cases of transperitoneal laparoscopic repair of RCU. All were male patients with average age of 29.6 years (14-50). Pain was their only complaint with normal renal function and no complications. After diagnosis with CT Urography, they underwent radionuclide scan and were operated on. Postoperative follow-up was done with ultrasonography every 3 months and repeat radionuclide scan at 6 months. The maximum follow-up was for 2.5 years. RESULTS: All cases were completed laparoscopically. Average operating time was 163.2 min. Blood loss varied from 50 to 100 cc. Ureteroureterostomy was done in all patients. None developed urinary leak or recurrent obstruction postoperatively. Maximum time for the requirement of external drainage was for 4 days (2-4 days). Average postoperative time for hospitalization was 3.8 days. Follow-up ultrasound and renal scan showed unobstructed drainage. CONCLUSIONS: Transperitoneal or retroperitoneal approach can be considered equivalent as parameters like operative time, results are comparable for these two modalities. We preferred transperitoneal approach as it provides good working space for intracorporeal suturing.
