ABSTRACT

A total of 300 patients [7-71 years old] with urinary stones were treated with a second-generation lithotripter [Lithostar]. All treatments were given on an out-patient basis. General anaesthesia was used only for one patient. Intravenous analgesia was used for 241 patients, while no sedation or analgesia was necessary in 58 patients. Auxiliary measures were required for 73 patients [27.3%]. Fragmentation was achieved in 96.6% of the cases. Stone-free status was achieved in 139 patients [68.1%], while 23 patients [11.4%] had insignificant residual, and 35 patients [17.3%] had significant residual stone fragments.
