[The treatment of patients with ureteral calculi by ureteroscopy and intracorporeal lithotripsy].

Ureteroscopy with endocorporeal urinary stone lithotripsy (EUSL) implies an "in situ" stone fragmentation including or not a basket extraction of the fragments. EUSL needs three conditions: ureteronephroscopy (antegrade or retrograde), sources of energy (ultrasonic, electrohydraulic, laser), extraction devices (basket, grasping forceps). The paper reports the data on 120 ureteral stones treated by ureteroscopy and laser lithotripsy with an overall effect of 84%.
