title: [Ureteroscopy for upper urinary tract stones].
abstract: Indication for ureteroscopy of an upper urinary tract stone depends on the location and size of the stone. For small proximal ureteral stones, first-line treatment is extracorporeal lithotripsy (ESWL). For big or distal ureteral stones, ureteroscopy (URS) is the more efficient urological treatment. URS has a higher morbidity than ESWL. URS must be careful, urines must be sterile, and a renal safety wire is mandatory. Ideal intracorporeal lithotripsy means are ballistic energy or holmium laser. Ureteral drainage is not always needed in case of easy monobloc removal of a small non impacted stone. In other cases an ureteral drainage is safer. The Stone Free rate of URS is 65-90%. The risk of ureteral stenosis is 1%.
