After the installation of the third generation Dornier MPL 9000 multipurpose lithotripter in Assiut University Hospital and within one year 460 patients suffering from renal calculi were treated using a modified ellipsoid with a larger skin to focus distance with increased coupling surface area. Single stone was encountered in [214 patients], two stones [91 patients], branched stones [39 patients], multiple stones [116 patients] Succesful disintegration was achieved in 94% with an average number of sessions 2.28.
