Abstract

Abstract:

Objective

To evaluate the efficacy and safety of digital flexible ureteroscope combined with U100Plus laser in the treatment of 2-3 cm upper urinary calculi.

Methods

The clinical data of 66 patients with 2-3 cm upper urinary tract calculi treated by digital flexible ureteroscope combined with U100Plus laser lithotripsy from February to June 2018 in Jinshazhou Hospital of Guangzhou University of Chinese Medicine and the Fifth Hospital of Guangzhou Medical University were retrospectively analyzed. The stone free rate in one month after operation was calculated, and the outcome of operation were observed, as well as complications (Clavin-Dindo classification).

Results

The mean diameter of stones were (2.3±0.3) cm, and the success lithotripsy rate of single-stage was 100%. The average time of lithotripsy was (56±24) min, and postoperative hospital stay was (2.3±1.2) days. The stone free rate (SFR) was 87.9% after one month. The incidence of surgical complications was 9.09% (6 cases), including Grade I in 4 cases, 3 cases had fever (>38.5℃), and one required analgesia for recurrent pain. 2 cases had ureteral steinstrasse (Grade IIIA) were performed ureteroscopic procedure to remove the stone.

Conclusion

Digital flexible ureteroscope combined with U100Plus laser in the treatment of 2-3 cm upper urinary calculi has high lithotripsy efficiency, fewer complications and high stone clearance rate.
