Ureteroscopic lithoclast lithotripsy: a cost-effective option.
Seventy-four consecutive cases of ureteral stones listed for ureteroscopic lithotripsy were studied prospectively. In all cases, the Wolf 7.5F or 9F ureteroscope was used in conjunction with the Swiss Lithoclast system. Dormia baskets were employed on four occasions to prevent forward propulsion of fragments. Ureteroscopic access to the stones was successful in 70 patients (95%). Lithoclast lithotripsy was successfully applied in 68 patients (92%), with complete fragmentation noted in 62 patients (91%), one requiring two sessions. The 6-week stone-free rate was 96% for these patients. Five patients with partial fragmentation had successful adjuvant SWL. The overall successful fragmentation rate was thus 84% (62 of 74) and 91% (67 of 74) in combination with adjuvant SWL. Cost analysis indicated a three-fold advantage for the Lithoclast over Candela lasertripsy. Ureteroscopic Lithoclast lithotripsy is a cost-effective treatment modality for ureteral stones.
