Abstract:
This is a first-rate, well thought out lithotriptor. It is very user friendly. Although not as powerful as some of the earlier devices, it has the distinct advantage of not causing any tissue damage during treatment. The advantage is the ability to vary the delivery of the amount of power according to the needs of the situation. The learning curve for the operator is steep, and he/she very quickly becomes very proficient. Patience is needed with some stones to give enough shocks for total fragmentation, but that comes with experience. Balancing the ease of treatment against the occasional need for retreatment results in a definite bias for the patient being treated with this machine, and avoiding the reported problems attendant with spark gap equipment. This, in my opinion, is an excellent machine.
