Comparison of the effect of ureteroscopic lithotripsy and extracorporeal shock wave lithotripsy for ureteral stones

Objective To compare the effect of ureteroscopic pneumatic lithotripsy(URL) and extracorporeal shock wave lithotripsy(ESWL) for ureteral stones.Methods 90 patients with ureteral stones were randomly divided into group A( URL group),group B( ESWL group),each group 45 cases.The effect of surgical treatment was compared between the two groups.Results The one-time success rate of gravel,stone free after 4 weeks of A group was significantly higher than that of group B( x2 =9.680,5.414,all P ＜0.05),but there was no significant difference in the surgical time and hospital stay of the two groups( t =1.010,0.909,all P ＞ 0.05 ).The postoperative renal colic,fever and other complications of group A were significantly lower than that of group B ( x2 =6.049,5.075,all P ＜0.05),but the gross heraturia and ureteral injury of group A was higher than that of group B(x2 =5.874,3.873,all P ＜ 0.05 ).Conclusion The ureteroscopic pneumatic lithotripsy and extracorporeal shock wave lithotripsy in the treatment of ureteral stones all have good effect,but ureteroscopic pneumatic lithotripsy and stone rubble drain success rate are significantly higher than extracorporeal shock wave lithotripsy,and postoperative complications are relatively less than extracorporeal shock wave lithotripsy.
