Abstract：To compare the the efficiency and security of modular flexible ureteroscopy and electronic flexible ureteroscopy for treating upper urinary calculi. Methods: From June 2014 to June 2015, 94 patients with upper urinary calculi were treated by modular flexible ureteroscopy (35 cases, group A) or electronic flexible ureteroscopy (59 cases, group B). Procedural time, success rate of surgery, complication rate and the residual stone rate were compared. Results: In groups A and B, success rate of surgery was 100% and 84.7% (P＜0.05), the cases of sepsis were 6 and 1 (P<0.05), procedural time was (32.6±7.3) min and (39.2±6.8) min (P<0.05), and the cases of residual stone were 2 and 4, respectively. Conclusions: Both modular flexible ureteroscopy and electronic flexible ureteroscopy are effective and safe therapeutic modalities. Electronic flexible ureteroscopy is better than modular flexible ureteroscopy in success rate of surgery because of its high definition and flexible operation. But after the training, modular flexible ureteroscopy also has good operation effect. And because of its thinner lens body, the complication rate of modular flexible ureteroscopy is lower.
