Children weighing less than 30kg, obese people weighing more than 135kg. Anatomical abnormalities: ureteral stenosis, horseshoe kidney... Failures of extracorporeal lithotripsy: The stone is too hard (Oxalate de Calcium Monohydrate, Cystine) not to be dispersed. The stone has been crushed but is deposited in the renal calyx, unable to be eliminated through the natural route. Kidney stones associated with urinary pathology can be effectively intervened through endoscopic renal route (narrowing of the ureteral junction, calyces diverticulum...).
