Randomized Controlled Trial Comparing Retroperitoneal Laparoscopic Pyelolithotomy Versus Percutaneous Nephrolithotomy for the Treatment of Large Renal Pelvic Calculi: A Pilot Study

Abstract

Current evidence suggests that PCNL and RLP are both effective and safe for the treatment of large renal pelvic calculi. Our study shows that, compared with the PCNL approach, RLP for large renal pelvic stone resulted in shorter operative time, less bleeding, less postoperative fever, and a higher stone-free rate. Data from larger, multicenter randomized controlled trials of high quality are needed to further confirm our findings.
