Clinical observation of flexible ureteroscopy combined with physical vibration lithecbole in treatment of massive upper urinary calculi / 中国内镜杂志

ABSTRACT

Objective To evaluate the clinical efficacy of flexible ureteroscopy combined with physical vibration lithecbole in treatment of massive upper urinary calculi. Methods The clinical data of 62 cases with massive upper urinary calculi from Feb 2016 to Mar 2017 were analyzed retrospectively. The average diameter of stones were (656.70 ± 275.40) mm2. The removal rate of stones, general conditions during the operation, the postoperative adverse reactions and renal function changes were observed. Results All 62 patients had successfully completed flexible ureteroscopy operation, and had physical vibration stone removal treatment after 1 week. The rate of stone removal was 61.29％ in the next day (38/62), 85.48％ (53/62) in the next 1 week and 96.77％ (60/62) in the next 3 weeks. Postoperative fever occurred in 2 cases, the overall complication rate was 3.23％. 18 patients had improved renal function while 4 patients keep stable after operation. Conclusion The flexible ureteroscopy combined with physical vibration lithecbole is a safe and effective therapeutic method for massive upper urinary calculi. It has high stone removal rate, less complications, little impact on renal function. It is valuable to advocate clinically.
