Ureteroscopic lithotripsy versus percutaneous nephrolithotomy in treatment of renal calculi

Abstract

Objective To explore the clinical effects of ureteroscopic lithotripsy and percutaneous nephrolithotomy in the treatment of renal calculi. Methods 85 cases of renal calculi treated at our hospital were randomly divided into a control group (n=42) and an observation group (n=43). The control group were treated with percutaneous nephrolithotomy, and the observation group with ureteroscopic lithotomy. The stone clearance rate, intraoperative bleeding volume, operation time, complication rate, and quality of life were compared between the two groups. Results The stone clearance rate in the observation group was 90.70% (39/43), while that in the control group was 92.86% (39/42), with no statistical difference between the two groups (P>0.05) . The operation time was longer and the bleeding volume was lower in the observation group than in the control group, with statistical difference (P<0.05) . The complication rate was lower in the observation group than in the control group [2.33% (1/43) vs. 19.05% (8/42), P<0.05]. Conclusion Ureteroscopic lithotripsy and percutaneous nephrolithotomy both are effective in treating renal calculi, but the former has lower bleeding volume and complication rate.
