Clinical comparison of two minimal invasive techniques in the treatment of benign prostatic enlargement over 90 ml: BIVAP (Richard Wolf®) saline vaporization of the prostate vs. bipolar plasmakinetic TURP

The aim of this study is to evaluate the efficacy, safety and postoperative outcomes of the recently developing endoscopic techniques of Bi-Vap (Richard Wolf®) saline vaporization of the prostate and bipolar plasmakinetic TURP in BPE over 90 ml. METHODS: In total, we included 147 patients treated with BiVap (Richard Wolf®) saline vaporization of the prostate (n=75) and bipolar plasmakinetic TURP(n=72). The inclusion criteria were Qmax ≤10 mL/s,IPSS ≥16, and prostate volume over 90 ml. Operation, hospitalization and catheter removal time were noted. Postoperative complications including urinary tract infection, transient hematuria, severe dysuria, and fever >38°C, urinary incontinence and urethral stricture were also noted. All patients were evaluated at the postoperative month 3. Preoperative and postoperative values of IPSS score, QoL score, IIEF-5, PVR, Qmax and Qave were compared. Statistical analyses were performed using SPSS 18.0 program and statistical significance was set at p
