[Contact lithotripsy. Advantages and disadvantages]

Abstract

OBJECTIVE: To review the different methods of contact lithotripsy by intracavitary direct contact or very close approximation of different rigid and flexible energy-transmitting devices (probes, fibers, etc.). METHODS: The systems commonly used, as well as those that have fallen into disuse or have not been developed further, are briefly described. RESULTS: Although no contact lithotripsy system is clearly superior over another, in our experience the electrokinetic system (Walz) is highly effective and simple to use. CONCLUSIONS: Contact lithotripsy permits stone disintegration and removal of fragments during the same surgical procedure. It improves the rate of completeness of stone removal and permits earlier functional recovery of the obstructed renal unit.
