Laparoscopic Pyelolithotomy in Selected Patients with Ectopic Pelvic Kidney: A Feasible Minimally Invasive Treatment Option

Abstract Background and Purpose: Ectopic pelvic kidney is a rare congenital anomaly. It carries more risks for obstruction and stone formation than a normal located kidney. The treatment of renal stones in these patients is challenging. We present our experience with laparoscopic pyelolithotomy for treatment of selected patients with large and multiple renal stones in ectopic pelvic kidneys. Patients and Methods: After insertion of a ureteral catheter, pneumoperitoneum was achieved by Veress needle, and the kidney was exposed. The renal pelvis was identified, dissected, and opened. The stones were extracted using laparoscopic forceps. The rigid nephroscope was used to extract any caliceal stones. The renal pelvis was sutured, and the stones were removed from the peritoneal cavity. The procedure was concluded after placement of an intraperitoneal drain. Results: A total of 11 patients with large renal pelvic and/or multiple stones underwent laparoscopic transperitoneal pyelolithotomy. A transmesenteric app...
