BACKGROUND: To establish the best treatment modality in our hospitals for patients with proximal-ureteral calculi 5 to 10 mm, we compared the treatment outcome in those who underwent primary ureteroscopy (URS) with that in patients who underwent primary in-situ SWL. The primary endpoints were stone-free rates at 3 weeks and 3 months and the subjective patient experience.
PATIENTS AND METHODS: The study was a prospective patient-preference trial. From September 2002 to May 2005, 80 patients were included, of whom 71 could be evaluated. Thirty-three patients were treated with SWL and 38 with semirigid or flexible URS. Stone status was evaluated with excretory urography or noncontrast helical CT. The bother score of urinary-tract symptoms was recorded on a visual analog scale.
RESULTS: The stone-free rate at 3 weeks was 58% and 78% (P = 0.061) and at 3 months 88% and 89% (P = 1) for SWL and URS, respectively. The percentage of patients in need of analgesics was 30% and 49% (P = 0.118) at 3 weeks and 9% and 21% (P = 0.181) at 3 months for the SWL and the URS group, respectively. The bother score regarding dysuria, hematuria, and flank pain were statistically significant in favor of SWL.
CONCLUSION: Ureteroscopy tends to make patients stone free faster, but SWL is preferred by most patients because there is less discomfort after treatment.
