Laparoscopic-assisted correction of a retrocaval ureter

Retrocaval ureter has been traditionally corrected surgically through an open retroperitoneal procedure; however, in recent years, the correction has been accomplished using laparoscopy. The great advantages of this procedure remain limited because of the prolonged time it takes to complete the intracorporeal suture of the ureter, besides the need for a highly experienced surgeon. We present a case in which the ureter was freed using laparoscopy, and the ureteral anastomosis was carried out extracorporeally, which notably diminished the duration of the surgery. This technique would have limited use in obese patients, patients with ureters of limited length, patients with very proximal obstructions of the ureter, and patients with risk of devascularization of both ureteral segments. However, the technique does appear effective and reproducible in adequately selected patients.
