Comparison of clinical efficacy of MPCNL and URL in impacted upper ureteral calculi

Objective To investigate the clinical effect of the minimally invasive percutaneous nephrolithotomy(MPCNL) comparing with transurethral ureteroscope lithotripsy(URL) in treating impacted upper ureteral calculi.Methods Ninety-eight cases of impacted upper ureteral calculi treated in our hospita1 from April 2010 to January 2012,including thirty-nine cases of MPCNL and fifty-nine cases of URL.Compared the clinical efficacy of the two kinds of surgical method.Results The operation time of MPCNL was(121.68±15.73) minutes,URL was(68.35±9.17)minutes.After MPCNL,the postoperation stone-free rate was 94.8%(37/39) in 3 days,and it was 100%(39/39) in a month.After URL the postoperation stone-free rate in 3 days and in a month were 57.63%(34/59) and 81.36%(48/59) respectively.Compared with URL group,MPCNL group in 3 days and 1 month postoperation got a higher stone-free rate(P0.05).The average postoperation hospital stay of MPCNL was(10±2.3)days and URL was(5±1.2)days(P0.05).Conclusions The operation time and the average postoperative hospital stay of URL are shorter than MPCNL,but the stone-free rate of MPCNL is higher than URL.
