Clinical study of combined pneumatic and ultrasound lithotripsy in the treatment of renal and upper ureteral calculi

Objective To investigate the application of percutaneous nephroscopic pneumatic and ultrasound lithotripsy kiyoishi system in renal and upper ureteral calculi.Methods One hundred and forty-two patients with upper ureteral calculi admitted in department of urology of our hospital,from Oct.2011 to Jan.2013 were selected as objects,of which 71 patients were treated by percutaneous nephrolithotomy with pneumatic removing stones,as the control group,and the remaining 71 patients were treated with percutaneous nephroscopic pneumatic and ultrasound lithotripsy kiyoishi system clear stone,as test group.Operation time,intraoperative bleeding volume,postoperative complication rate and stone clarance rate were compared between the two groups.Results The operation time was(93.12 ± 12.32) min,the intraoperative bleeding volume was(50.32 ± 15.67) ml,the postoperative complication rate was 4.2%,and the stone clearance rate was 86.7% in test group;the operation time was(124.20 ± 12.65) min,the intraoperative bleeding volume was(90.23 ± 17.81) ml,the postoperative complication rate was 15.5%,and the stone clearance rate was 75.6% in control group.The operation time,intraoperative bleeding volume and postoperative complication rate were less than that in the control group,and the stone clearance rate was higher than that in the control group,the differences were significant(P 0.05).Conclusion Percutaneous nephroscopic pneumatic and ultrasound lithotripsy kiyoishi system has high clearance rate of renal and upper ureteral calculi and less postoperative complications,so is worth to be clinical promoted.
