Clinical efficacy of ureteral stent in coordinating extracorporeal shock wave lithotripsy for the treatment of 182 cases of upper urinary tract radioparent calculus

Objective To observe the clinical effect of ureteral stent in coordinating extracorporeal shock wave lithotripsy for the treatment of upper urinary tract radioparent calculus. Methods From 2013 to 2016, 182 cases of upper urinary tract radioparent calculus were collected. The ureteral stent (including common stent and double J tube) was used before the treatment. Results 165 cases were effective, and 17 cases were not effective, with the total effective rate of 90.65%. No severe complications were found in all cases. Conclusion Ureteral stent in coordinating extracorporeal shock wave lithotripsy for the treatment of upper urinary tract radioparent calculus is safe, effective, and easy and simple to handle.
