Abstract:Objective: To discuss the effectiveness and safety of flexible ureteroscope in the treatment of renal and ureteral calculi and investigate the techniques of the procedure with flexible ureteroscope during clinical practice. Methods: Between March 2014 and April 2016, 860 cases of renal and ureteral calculi were treated with flexible ureteroscope combined with holmium laser treatment, including 406 cases of simple renal calculi with (1.45±0.46) cm in diameter and 178 cases of simple ureteral calculi with (0.92±0.24) cm in diameter, and 276 cases of renal and ureteral calculi [including renal calculi of (0.91±0.47) cm in diameter and ureteral calculi of (0.85±0.23) cm in diameter]. Results: Double-J tube was not placed before operation. The success rate of one-stage operation was 98.84%. The success rate of sheath placement at a single attempt was 96.28%. The incidence of another lithotripsy was 2.21%. The duration of operation was (61.72±31.20) min. The volume of blood loss during operation was (3.40±2.88) mL. The duration of hospitalization after operation was (5.30±3.33) days (excluding patients with another operation). The incidence of complications after operation was 11.86%. The percentage of patients without calculus one month after operation was 72%. The percentage of patients without calculus 3 months after operation was 86%.Conclusions: The flexible ureteroscope combined with holmium laser treatment was safe and effective for renal and ureteral calculus, which features high success rate and rapid recovery after operation and less complications. The success rate of one-stage operation was high. For patients whose calculi are difficult to break, the modification of operation technique can significantly improve the success rate.
