A retrospective analysis was carried out on 193 patients who underwent ureteroscopy for ureteral stones with a miniscope associated with either an electrohydraulic or a pneumatic lithotriptor. Complete stone fragmentation with spontaneous expulsion of the fragments occurred with just one session in 89.1% of cases. Nine patients underwent ureterolithotomy. The only complications were 3 ureteral lesions without perforation. The authors consider that with these mini instruments, there is a very low rate of morbidity connected with this procedure, which can therefore be given first option in the treatment of lower ureteral stones.
