Management of ureteral calculi with the use of transurethral ureteroscopy and electrohydraulic lithotripsy: 101 patients experience.

ABSTRACT

To evaluate the results of transurethral ureteroscopy and electrohydraulic lithotripsy for ureteral calculi needing surgical management. From 1993 to 1995, 101 patients with ureteral calculi were retrospectively analyzed. The locations and sizes of the calculi were examined and the success rate of the procedure was assessed. The overall success rate was 74%. The success rates of upper and lower ureteral calculi were 67% and 81%, respectively. The stone size did not affect the success rates. Among the failure patients, there were no serious complications and they could be subsequently treated with either ureterolithotomy or double J stent replacement. The median hospitalization was 4 days. Transurethral ureteroscopy and electrohydraulic lithotripsy is an effective and safe procedure for ureteral calculi treatment. This method is a minimally invasive procedure and involves a short hospital stay.
