PURPOSE: We assess the efficacy and safety of semirigid ureteroscopy for treatment of ureteral stones in children. MATERIALS AND METHODS: The records of 18 non-consecutive children with symptomatic ureteral stones treated with ureteroscopy in 2008-2010 were reviewed. Mean age was 7.6 years (range 15 months-14 years). A semirigid (8F) ureteroscope was used in all cases. A 0.038-inch floppy-tipped guidewire was passed through the selected ureteric orifice, advanced under direct vision, and monitored fluoroscopically. Dilatation of the ureteral orifice was necessary in 7 cases. Either direct extraction or disintegration using a pneumatic lithotripter was performed. The follow-up period was 6 months. RESULTS: Ureteroscopic procedures were successfully completed in 16 children (89%). Stones were located at the middle ureter in 3 (19%) cases and various levels of the lower third ureter in 13 (81%) cases. Stone size was 4-10 mm (mean 7 mm). Stones were fragmented with pneumatic lithotripsy in 9 (56%) cases and removed by forceps without fragmentation in 7 (44%). Stent was left in place for 3 days to 3 weeks in 12 (75%) cases. Early postoperative complications were insignificant hematuria in 2 patients and renal colic and fever in 3 patients. No complications were observed during the period of follow up. CONCLUSION: Ureteroscopy is a feasible treatment option for ureteral stones in children, when in skilled hands and with the aid of experience gained in the adult population.
