Efficacy of percutaneous nephrolithotomy with pneumatic and ultrasonic lithotripsy guided by ultrasound for horseshoe kidney with calculi

Aim:To investigate the feasibility of percutaneous nephrolithotomy(PCNL) with pneumatic and ultrasonic lithotripsy under ultrasound guidance for horseshoe kidney with calculi.Methods:Clinical data of 46 cases of horseshoe kidney with calculi treated by PCNL with pneumatic and ultrasonic lithotripsy under ultrasound guidance were retrospectively analyzed.Results:The 46 cases were successfully established artificial calculus-extracting passage with one-stage operation.The average hospitalization time was 5.0～17.0(6.9±1.8) days,operation time was 46～121(75±24) min,calculi processing time was 31～68(49±17) min,and the average blood loss was 28～92(60±31) mL.All patients did not transfuse blood;calculi-free rate was 82.6%(38/46) with one-stage operation,and that was 91.3%(42/46) with two-stage operation.Two cases accepted postoperative adjuvant extracoporeal shock wave lithotripsy,and total calculi clearance rate reached 95.7%(44/46).There was no associated complication.Conclusion:PCNL with pneumatic and ultrasonic lithotripsy under ultrasound guidance is safe and reliable for horseshoe kidney with calculi.
