ABSTRACT
Objective To evaluate the therapeutic effect of ureteroscopy with holmium laser on ureteral stricture associated with calculi.Methods The clinical data of 36 cases of ureteral stricture associated with calculi undergoing ureteroscopy with holmium laser treatment were analyzed retrospectively with 26 cases of male patients and 10 cases of female patients.The age was 26-65 years.There were upper and middle ureteral stricture associated with calculi in 8 cases,and lower segment of ureteral stricture associated with calculi in 28 cases.All the patients were treated with ureteroscopy with holmium laser.All cases were followed up for 6-12 months.In the follow-up of 36 cases B ultrasound and urinary tract flat piece or intravenous urinary tract imaging were performed to evaluate the therapeutic effect.Results Thirty-six patients underwent ureteroscopy with holmium laser successfully.No conversion to open surgery occurred.Mean operating time was 30 (20-45) min.Mean hospital stay postoperatively was 3-5 d.Postoperative 8 cases with low thermal,alleviated by the anti-infection treatment,no ureteral avulsion,leakage and severe complications such as hemorrhage.Postoperative follow-up,32 cases (89％,32/36) were cured and 4 cases (11％,4/36) were improved.Conclusion Ureteroscopy with holmium laser in treatment of ureteral stricture associated with calculi is a simple and effective minimally invasive method.
