Treatment of ureteral calculi with ureteroscopy and pneumatic lithotripsy: A report of 110 cases / 中国微创外科杂志

ABSTRACT

Objective To evaluate the clinical efficacy of pneumatic lithotripsy under ureteroscope in the treatment of ureteral calculi. Methods A total of 110 cases of ureteral calculi were treated by using 8/9.8 F Wolf rigid ureteroscope and JUN-AIR pneumatic lithotripter. Results Successful lithotripsy under ureteroscope was achieved on one session in 105 cases, with a success rate of 955% (105/110). Calculi were entirely extracted within 1~6 weeks. Conversions to open surgery were required in 2 cases because of failed ureteroscope insertion. Upper ureteral stones moved into the kidney in 3 cases, 2 of which underwent the ESWL and 1 of which received medical treatment. Postoperatively, 5 cases were complicated with urinary infection with mild hematuria lasting for 1~3 days. Conclusions Pneumatic lithotripsy under ureteroscope is an effective method for treating mid-lower ureteral calculi, with advantages of high efficiency, safety, minimal invasion, less complications and simplicity of performance.
