Flexible ureterorenoscopy to treat upper urinary tract stones in children

Development of surgical expertise and technology has affected the way renal tract stones are treated. Our hypothesis was that flexible ureteroscopy (FURS) for upper tract stones in children produces good results. Our outcomes were reviewed. A retrospective case note review was performed for children with upper tract calculi who were treated by FURS. There were 56 stone episodes in 36 patients. Median age was 10.6 years. Stones were 3-23 mm (median 8 mm); 64.3% had multiple calculi. Median follow-up was for 17.1 months. After the first FURS there was stone clearance in 42/56 (75%). Although there were no immediate complications, two required re-admission; one with stent symptoms, the other with urinary infection. A second FURS was performed in 11, bringing the cumulative clearance to 89%, although this was often done as "another look" before stent removal. There was no statistically significant difference in stone clearance after first FURS for those with single stones (81.0%) compared to those with multiple stones (72.2%). Clearance rates of more than 70% after first FURS were achieved with stones of up to 17 mm. Unexpected disease was found and treated during FURS in 9 (16.1%) children. FURS is safe in children and good clearance rates are achieved. Multiple stones at different sites may be treated during the same treatment. In addition, FURS allows diagnosis and treatment of unexpected problems.
