However, issues that have not yet been overcome for TURP include bleeding and absorption of irrigation fluid. Thus, novel improvement of the surgery is necessary. This study aimed to evaluate the efficacy and safety of bipolar plasma vaporization of the prostate （BPVP） with ＂button-type＂ electrode against standard TURP for BPH.展开更多
