The 'Wing' versus the 'Vapor Cut' electrodes in transurethral electrovaporization-resection of the prostate: comparative changes in safety parameters.

We compared the early safety features of two-band resection devices used in transurethral vaporization-resection of the prostate (TUVRP). Ninety patients with prostatic outflow obstruction were prospectively evaluated in two open studies for the treatment using the 'Wing' cutting electrode in group 1 (Richard Wolf, Germany) and the 'Vapor Cut' electrode in group 2 (Karl Storz, Germany). Patients in both groups were comparable in age, presentation, prostate size and blood parameters.
