Comparison of two surgical treatments for upper ureteral calculi after translocation during the same period

Abstract

Objective To explore the method of improving the clinical efficacy in the treatment of upper ureteral calculi. Methods Clinical data of 68 patients with upper ureteral calculus and translocation during surgery admitted to our department from July, 2012 to May, 2017 were retrospectively analyzed. All 68 patients were treated with ureteroscopic lithotripsy under general anesthesia, and calculus displacement occurred during the operation. Thirty-two patients underwent minimally invasive percutaneous nephrolithotomy (MPCNL) and 36 patients were treated with retrograde intra-renal surgery (RIRS). The clinical efficacy and postoperative complications were analyzed. Results A total of 32 cases were treated with MPCNL and the success rate of lithotripsy was 93.8%. Thirty-six patients underwent RIRS and the success rate of lithotripsy was 100%. Patients in the RIRS group obtained faster postoperative recovery and shorter length of hospital stay than their counterparts in the MPCNL group. No blood transfusion, ureteral perforation, or other severe complications such as massive hemorrhage and ureteral stricture occurred during postoperative follow-up for 3-6 months. Conclusions RIRS can be the primary treatment of the upper ureteral calculi migrating to the kidney during ureteroscopic lithotripsy.
