Laparoscopic ureteroureterostomy for retrocaval ureter

Two cases of retrocaval ureter are reported that were successfully treated by a laparoscopic approach. Case 1 was a 20-year-old woman who presented wi th symptoms of a right ureter stone. Case 2 was a 23-year-old woman who had suffered from recurrent right flank pain with gross hematuria. A transperi toneal approach was used for case 1, and a retroperitoneal approach was use d in case 2. Both were successfully treated with laparoscopic ureteroureter ostomy using an intracorporeal suture technique. Laparoscopic surgery shoul d be the first choice for retrocaval ureter not only because of the minimal invasiveness but also because of the cosmetic advantage compared to conven tional open surgery. Further technical and instrumental advances are essent ial for intracorporeal suturing.
