Clinical efficacy of treating staghorn calculi under percutaneous nephrolithotomy combined with ultrasonic and pneumatic lithotripsy guided by B ultrasonography

Objective To evaluate the clinical efficacy of treating staghorn calculi under percutaneous nephrolithotomy(PCNL)combined with ultrasonic and pneumatic lithotripsy guided by B ultrasonography.Methods A total of 150 patients with staghorn calculi were treated with PCNL combined with EMS guided by ultrasound.Results Overall,the average operation time was 83 min,perioperative bleeding volume was 142 mL,average postoperative hospital stay was 6.1 days and clearance rate of stone was 92%.The average operation time,bleeding volume,hospitalization time,and stone clearance rate of partial staghorn calculi and complete staghorn calculi was 72,117 min,128,183 mL,5.9,6.7 days,and 94.7%,83.8%,respectively.No severe complication was observed after operation.Conclusion PCNL combined with pneumatic and ultrasonic lithotripsy is safe and effective for renal calculus and it is the preferred method for the treatment of staghorn calculi.
