Less-invasive therapy for pediatric urolithiasis is available due to the miniaturization of equipment and improved optics; however, surgical treatment strategies, especially for large calculi, remain controversial. We describe here our experience of treating a 2-year-old boy with left renal staghorn calculi with a single session of mini-endoscopic combined intrarenal surgery in the prone split-leg position with pre-ureteral stenting and the directional enhanced flow imaging ultrasound technique. This is the first report of successful pediatric mini-endoscopic combined intrarenal surgery without any major complications. We believe this technique provides an important therapeutic option for large renal calculus in pediatric patients.
