The apparatus includes an ellipsoidal reflection chamber having two focal points, one to be aligned with the concrement to be destroyed, the other one being located in a discharge path between two electrodes facing each other and being oriented in the longitudinal axis of the ellipsoid; one of the electrodes is a point-like extension of an inner one of two coaxial conductors, and the outer one of these conductors carries several flat arch shaped holders positioning the other electrode likewise in said longitudinal axis, the holding structure in the vicinity of the inner conductor continuing the ellipsoidal reflecting surface; through a threaded mount the two electrodes can be moved towards and away from each other; each of these electrodes is preferably provided for easy exchange to compensate burning off.
