Objective To investigate the efficacy and safety of Shuo Tong ureteroscopy in the treatment of upper ureteric stones.Methods The data of 832 patients,who underwent Shuo Tong ureteroscopy combined with holmium laser for the treatment of upper ureteric stones were collected between July 2014 and February 2017.The patients accepted general anesthesia under lithotomy position.After dilating the ureter,a ureteral access sheath was inserted along the guide wire.Finally,stones were broken and clean up by Shuo Tong ureteroscope.According to the stone size,823 patients were divided into ≤2.0 cm group (n=112,13.6％),2.1-3.0 cm group (n =395,48.0％),3.1-4.0 cm group (n =257,31.2％),＞ 4.0 cm group (n =59,7.2％)The stone free rate(SFR) and post-operative complications were observed.Results Among 983 operations,663 cases accepted one-stage operations and 160 cases accepted second stage operations.the operative time and postoperative hospital stay were 23-145 min(mean 74.8 ± 35.3) and 1-5 days(mean 1.9 ±0.8),respectively.The SFR in the first day and one month after operation was 75.6％ and 83.8％,respectively.The stone free rate in each group were 89.3％,82.5％,61.1％,52.5％ at first day after operation respectively(P ＜ 0.05).While,the SFR after one month were 95.5％,87.6％,72.0％,61.0％ in each group,respectively(P ＜ 0.05).Fever rate after operation was 11.1％,ureteral injury rate was 1.9％,severe hematuria rate was 0.6％,stone street formation rate was 1.2％,perirenal hematoma rate was 0.4％.All patients were improved after conventional treatment.Conclusion Shuo Tong ureteroscopy is a safe treatment with high stone free rate for upper ureteric stones.
