title: Laparsocopic ureteroureterostomy for retrocaval ureter.
abstract: 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 with 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 transperitoneal approach was used for case 1, and a retroperitoneal approach was used in case 2. Both were successfully treated with laparoscopic ureteroureterostomy using an intracorporeal suture technique. Laparoscopic surgery should be the first choice for retrocaval ureter not only because of the minimal invasiveness but also because of the cosmetic advantage compared to conventional open surgery. Further technical and instrumental advances are essential for intracorporeal suturing.
