Introduction: We aimed to describe our experience in transperitoneal laparoscopic repair of retrocaval ureter (RCU) in this study. Methods: Between February 2010 and February 2017, five patients (1 female and 4 males) who underwent laparoscopic repair with the diagnosis of RCU in our department were included in this study. Patients' mean age was 27 (range 20-32 years). All patients were pre-operatively evaluated using ultrasonography (US) followed by contrast-enhanced computed tomography (CT) intravenous pyelography (IVP). After CT diagnosis of RCU, all patients underwent diuretic renography examination with 99mTc-DTPA. Laparoscopic surgery was performed by the transperitoneal approach using the three-dimensional (3D) vision system in two and two-dimensional vision system (2D) in three patients. Results: All operations were completed laparoscopically without conversion to open surgery. Mean operation time was 168.5±9.89 minutes. Operation time of two patients in whom 3D a vision system was used was shorter (155 and 165 minutes) comparing to others in whom 2D vision systems used. Blood loss was less than 50 mL in all patients. Obliterated ureteric segments were excised in four patients. Four patients were symptom-free after surgery and had regression of hydronephrosis in their kidneys. In one of the cases, there was no resolution of hydronephrosis postoperatively. Discussion and Conclusion: Careful dissection along the planes with good tissue respect and good hemostasis during each step are the key to success for laparoscopic repair of RCU. Pure laparoscopic treatment of RCU seems feasible and technically reliable. At the same, time using a 3D vision system, if available would be preferable because of the dissection and intracorporeal suturing advantages.

Introduction. Retrocaval ureter is a rare congenital anomaly. Open surgery was the classic treatment for this condition. Laparoscopy is currently an admitted procedure to treat many urological diseases. The objective of our study is to present our experience and discuss the safety and the feasibility of transperitoneal laparoscopic pyelopyelostomy for treatment of retrocaval ureter (RCU). Materials and Methods. Three symptomatic patients underwent laparoscopic repair for RCU in our department. The diagnosis was suspected on the computed tomography scan (CT) and confirmed on ascending pyelography. After placement of a JJ stent, and, using the transperitoneal approach, the retro peritoneum was exposed; the ureter was identified in both sides of the vena cava. The retrocaval segment was entirely mobilized and pulled from behind of the vena cava after section of renal pelvis. A pyelopyelostomy was done in a normal anatomic position. Results. All operations were achieved laparoscopically without conversion to open surgery. The mean operative time was 140 minutes (110–190). No intraoperative complication occurred. Blood loss was less than 50 mL in all patients. The mean hospital stay was 5 days (4–6 days). All patients were symptom-free after surgery and had reduction of hydronephrosis in control imagery. Conclusion. Laparoscopy seems safe, feasible, and reproducible in managing retrocaval ureter.

“…Laparoscopic UU has been reported for the treatment of benign ureteral strictures, iatrogenic injury during gynecological surgery, and retrocaval ureter [1] , [4] . UU is traditionally performed through open surgery, but it has recently been increasingly performed through several minimally invasive techniques, including laparoscopic, robot-assisted, and LESS UU [1] , [2] , [3] .…”
