[Ballistic (Lithoclast) and hydro-electric (Riwolith) endo-ureteral lithotripsy. Report of 60 cases].
25 hydroelectric endoureteric lithotripsies (Group 1, Riwolith) and 35 ballistic endoureteric lithotripsies (Group 2, Lithoclast) were analysed. 60 stones were treated, including 18 pelvic stones (Group 1 : 10, Group 2 : 8), 39 iliolumbar stones (Group 1 : 14, Group 2 : 25), and 3 stones of the ureteropelvic junction (Group 1 : 1, Group 2 : 2). The mean maximal diameter was 9.9 mm (Group 1 : 8.2, Group 2 : 11). Complementary Dormia extraction was performed in 24 cases (Group 1 : 8, Group 2 : 16), 55 double J stents were implanted (Group 1 : 24, Group 2 : 31) and 23 immediate ECL sessions were performed (Group 1 : 8, Group 2 : 15). Overall, 57 good results were recorded, but 3 complete failures of fragmentation and 2 severe ureteric lesions were attributed to hydroelectric lithotripsy. The Lithoclast, much less traumatic, had a greater stone fragmentation potential, but its efficacy on very mobile stones is limited due to its more intense stone propulsion effect.
