Single trocar retroperitoneoscopic assisted ipsilateral ureteroureterostomy for ureteral duplication.

The aim of this study is to present the technique and early outcomes of single trocar retroperitoneoscopic assisted ureteroureterostomy for ureteral duplication. The patient was placed in a lateral decubitus position. A skin incision of 11 mm width was made above the iliac crest. The operation was performed through single trocar with operating laparoscope. The two ureters were encircled with a vessel loop and exteriorized outside the retroperitoneal space via trocar incision. The pathologic ureter was divided as low as possible. The recipient ureter was opened longitudinally. End-to-side ureteroureterostomy anastomosis was performed extracorporeally with two running 6/0 PDS sutures. From December 2010 to July 2011, nine patients were operated on using the same technique. Patient's ages ranged from 2 to 72 months. Mean operative time was 78 ± 21 min. There were no intra or postoperative complications. Postoperative stay was 2.6 ± 1.0 days. Follow-up revealed that two renal moieties preserved their functions in all patients. The diameter of involved ureters and pelvises was significantly reduced in all patients. Single trocar retroperitoneoscopic assisted ureteroureterostomy is safe and effective procedure for ureteral duplication.
