To demonstrate the feasibility of retrograde intrarenal surgery (RIRS) in pediatric age group.


Data of patients who underwent RIRS for the treatment of kidney stones were retrospectively analyzed. The procedure was performed using 7.5 Fr FlexX™ 2 flexible ureterorenoscope in all patients. Ureteral access sheath was not used in any patients. A double-j stent was inserted and the procedure was delayed for 2 weeks whenever access to the ureter was not possible. The stones were fragmented using laser and fragments smaller than 2 mm were left for spontaneous passage. Postoperative success was evaluated using ultrasonography and kidney, ureter and bladder (KUB) x-ray.


14 patients with a mean age of 7.5±2.47 (range: 3-12) years were included. Male to female ratio was 8/6 and six patients had a stone on the right side. The mean stone size was 12.3±3.49 (range: 8-20) mm. Of the patients, 10 had a history of unsuccessful shock wave lithotripsy (SWL) treatment. Mean operation and fluoroscopy screening times were 33.5±6.9 (range: 25-45) and 45.3±15.4 (range: 30-75) minutes, respectively. The median hospital stay was 1.07±0.2 (range: 1-2) days. No major complications were noticed during the operation. Double-J stents were removed on the 2nd postoperative week and all patients were stone-free during the follow-up.


RIRS can be performed safely and efficaciously in pediatric patients.
