[Flexible ureteroscopic lithotripsy in a 22-months-old child].

With the endourological development, the management of urinary tract calculi in children has significantly improved. The miniaturization of endoscopic equipment has allowed the use of flexible ureteroscopic with holmium YAG laser lithotripsy in children. We highlighted the case of a 22-month-old child, with an antecedent of megaureter, who had calculi in the right kidney lower pole. In collaboration with the urologist specialising in adult care, using an adapted technical tray, we underwent a laser intracorporeal lithotripsy using a 8 Charriere (Ch) ureteroscope and an holmium laser. No ureteral dilatation was required. A complete fragmentation of this infectious calculus was performed. This experience with a flexible ureteroscopy confirms that this technique is practicable, efficient and safe for stone treatment in children.
