Laparoscopic surgical correction of circumcaval ureter

Abstract

Laparoscopic transposition and reanastomosis of a circumcaval ureter were performed in a 52-year-old man with right flank pain. A preoperative perfusion pressure study revealed abnormally high intrapelvic pressure. Under laparoscopy, the renal pelvis was divided above the ureteropelvic junction and the ureter was relocated from behind the vena cava. A 5 cm segment of redundant ureter containing the postcaval segment was resected and the ureteral end and renal pelvis were reapproximated with interrupted sutures by intracorporeal knot typing. The postoperative convalescence was uneventful, not necessitating the administration of analgesics. The patient resumed full activities 3 weeks later. The intravenous urogram and renogram obtained 2 months after the operation revealed remarkable improvement in the ureteral obstruction.
