Efficacy of retroperitoneal laparoscopic nephrolithotomy vs. percutaneous nephrolithotomy in patients with complex renal calculi

Abstract

Objectives To compare the efficacy between retroperitoneal laparoscopic nephrolithotomy and percutaneous nephrolithotomy (PNL) in patients with complex renal calculi. Methods Clinical data for 126 patients with complex renal calculi from January2010 to December 2014 were reviewed. They were divided into laparoscopic group (n=54) underwent retroperitoneal laparoscopic nephrolithotomy and PNL group (n=72) underwent PNL. The condition related to surgery and indexes for therapeutic effects between the two groups were compared. Results All of the patients underwent surgery successfully and no perioperative death occurred. In the laparoscopic group, operative time was longer than that in the PNL group(P 0.05). In the laparoscopic group, the rate of two-stage operation was higher than that in the PNL group(P<0.05), and intraoperative stone-free rate was lower than that in the PNL group (P<0.05). After two-stage operation, the postoperative stone-free rate was 100%. Conclusions Laparoscopic biliary tract surgery for choledocholithiasis in elderly patients is safe and effective. But surgeons should grasp the operation indication flexibly and optimize the perioperative management. Key words: Kidney Calculi; Laparoscopes; Nephrostomy, Percutaneous
