The Efficacy Comparison of Percutaneous Nephrolithotomy and Ureteroscopic Lithotripsy for the Treatment of Impacted Upper Ureteral Stones

Objective To observe and compare therapeutic effect and security of percutaneous nephrolithotomy and ureteroscopic lithotripsy for the treatment of impacted upper ureteral stones.Methods 203 patients with impacted upper ureteral stones were chose in the period from March 2009 to May 2011 in our hospital and randomly divided into two groups including control group(51 patients) with ureteroscopic lithotripsy treatment and experimental group(46 patients) with percutaneous nephrolithotomy treatment;and after treatment the operative time,hospital staying time,the hemoglobin decreased degree,the stone clearance rate and complication incidence were compared.Results The operative time and hospital staying time,the hemoglobin decreased degree of experimental group were significantly higher than control group(P0.05).The stone clearance rate of experimental group were significantly higher than control group(P 0.05).And there was no significant difference in hospital staying time and complication incidence between control group and experimental group(P0.05).Conclusion The percutaneous nephrolithotomy on impacted upper ureteral stones obtain excellent effect,can effectively improve the stone clearance rate,have no serious complication and is worthy of clinical application.
