[Preliminary results of extracorporeal lithotripsy under local anesthesia using a multimodal generator (Tri-gen Compact Direx C)].

From April till October 1994, 64 patients were treated with the new generation of Direx lithotriptors, the Trigen Compact. The treatment was given in one-day clinic. The preparation is made of an intravenous hydratation, Dipidolor intra-muscular, Voltaren intra-rectal and Emla on the skin in the area of the shocks. Only 38 patients are estimated at three months. The first results are encouraging, with globally 78% of good results (stone free or residual fragments inferior to 5 mm) and 22% of failure. The best results (90%) are obtained with the ureteral stones. The results of the treatments of caliceal and pyelo-lithiasis are a little bit less good, with respectively 78 and 71% of good results. These data should become better when all the patients will be estimated at 3 months.
