Efficacy Analysis of Minimally Invasive Percutaneous Nephrolithotomy in Treatment of Complicated Uretera Calculi

Objective To evaluate the clinical effect of minimally invasive percutaneous nephrolithotomy (mPCNL) in treatment of complex upper ureteral calculi. Methods The clinical data of 180 patients with complex upper ureteral calculi treated by Mpcnl were retrospectively analyzed. Results Operation time was 80 to 120 minutes, with an average of (90 ± 10) minutes. One-time surgical success rate was 100%, and one-time stone-free rate was 99%, without additional surgical interventione and no serious complications. Conclusions Ninimally invasive percutaneous nephrolithotomy has the advantages of less trauma, faster recovery, higher stones depletion rate, safety and effectiveness, which can be used as first option in treatment of complex upper ureteral calculi.
