Complete Transperitoneal Laparoscopic Nephroureterectomy in Circumcaval Ureter with Upper Tract TCC: Initial Case Report

Abstract

Transitional-cell carcinoma (TCC) of the upper tract in a case of circumcaval ureter (CCU) is a rare entity. Laparoscopic transperitoneal nephroureterectomy in such case represents a unique challenge in the era of minimally invasive surgery. We report a case of complete transperitoneal laparoscopic nephroureterectomy with bladder cuff excision done for TCC in a case of CCU. This case report describes the first point of technique of the procedure done for this rare entity. A 38-year-old male patient underwent the procedure for high-grade TCC of right lower calix. The essential tenets of the procedure included performance of the technique in a manner contrary to the conventional nephroureterectomy. The case report describes the procedure in the following steps: management of lower ureter and bladder cuff followed upper tract procedure after transposition of bladder cuff posterior to inferior vena cava. The procedure was accomplished utilizing four ports and a 6 cm Pfannenstiel incision with operative time of 220 minutes and blood loss of 50 mL.
