title: Electrohydraulic cystolithotripsy.
abstract: The protocol and technique of electrohydraulic cystolithotripsy with the SD-1 for the crushing of the bladder calculi is outlined. In our opinion, the instrument is safe and an effective adjunct to the urologist. Urate, phosphate, and carbonate calculi are easy to crush. Oxalate and uric acid stones are more resistant to fragmentation. The procedure is superior to the conventional methods with blind or optical lithotriptors. The method is easy to learn, and application of this technique may be combined in the same session with other urologic procedures; this procedure opens up a new avenue in the treatment of urinary calculous disease.
