Despite subjective and objective success rates approaching 90%, significant morbidity is well documented using a wire loop for standard transurethral resection of the prostate (TURP). In an effort to minimize patient morbidity as well as limit future healthcare costs, several alternative instrumental techniques have been examined. Recent studies of transurethral electrovaporization of the prostate, a modification of existing transurethral technology, appear encouraging. The modifications which enable larger volumes of tissue to be vaporized with concurrent desiccation and coagulation are an increase in the surface area of the electrode and effective delivery of high electrical energy by electrical generators. The most extensively studied instrument is the VaporTrode. Promising early published reports of TURP-like efficacy without significant morbidity, as well as low cost, have fueled the popularity and wide application of this technique.
