Shock wave lithotripsy versus ureteroscopy for distal ureteral calculi: a prospective study.
We performed a prospective, non-randomised study to determine the appropriate first-line treatment modality for distal ureteral stones. Between 2003 and 2004, a total of 124 patients with distal ureteral calculi were entered into the study (mean age 48 years, 35 women and 99 men). Sixty-two patients were treated with shock wave lithotripsy (SWL) and 62 patients with ureteroscopy (URS). The average stone size was 6.9 mm (3-33 mm) for SWL and 7.2 mm (3-30 mm) for URS. The treatment decision depended on the patients' preference and clinical parameters (i.e. contraindications for anaesthesia). URS was performed under general anaesthesia, using semirigid 8 Fr instruments. SWL was performed under analgo-sedation using a Modulith SLX. Of patients treated with SWL, 84% had a treatment success within 7 days, 98% after URS. These results show a significant success (P=0.005) in favour of URS. The average in-patient stay after SWL was 3 days and for URS 4 days (not significant). The results show a high efficacy and a low complication rate for both modalities. The attained stone-free rate shows a significant advantage for primary URS.
