[Treatment of urinary stones in infants].

Up until the beginning of the 1990s, surgery was the only available modality for the treatment of renal and ureteric stones in infants. From 1990 onwards, two new minimally invasive techniques were developed, leading to a real revolution in the management of these patients. The first and most spectacular breakthrough was extension of the application of ESWL to this age-group and the second breakthrough was ureteroscopy following the enormous technological progress in the manufacture of endoscopes. This technique is increasingly useful when lithotripsy is impossible or insufficient. Surgery is still indicated in the case of contraindications to minimally invasive methods or after failure of these methods. It is the method of choice for bladder stones. Medical treatment or watchful waiting have valuable indications, at the cost of regular clinical and radiological follow-up of patients. The choice of treatment modality depends on the size of the stone, its site, its composition, the anatomy of the urinary tract and the availability of the various techniques.
