OBJECTIVE: To evaluate in a prospective, randomized trial the surgical efficiency and safety of a new energy source enabling a continuous bipolar plasma vaporization of the prostate (C-BPVP) to be achieved by comparison to the standard vaporization (S-BPVP) and monopolar TURP in medium size BPH cases. To comparatively assess the short term functional outcome of the 3 methods.
PATIENTS AND METHODS: A total of 180 BPH patients with prostate volume between 30 and 80 mL, maximum flow rate (Qmax ) below 10 mL/s and International Prostate Symptom Score (IPSS) over 19 were equally randomized for C-BPVP, S-BPVP and TURP. All cases were evaluated preoperatively and at 1, 3 and 6 months after surgery by IPSS, Qmax , quality of life score (QoL) and post-voiding residual urinary volume (PVR). The prostate volume and PSA level were postoperatively assessed at 6 months.
RESULTS: The mean operation time was significantly reduced in C-BPVP cases by comparison to the conventional plasma-button vaporization and resection, thus emphasizing a substantial 22.4% and respectively 39.1% decrease in surgical length in favour of C-BPVP when compared to S-BPVP and TURP. The mean haemoglobin level drops (0.4 and 0.6 versus 1.4 g/dL), capsular perforation (1.7% and 3.3% versus 10%) and postoperative hematuria (1.7% and 1.7% versus 13.3%) rates, catheterization periods (24.1 and 23.9 versus 73.6 hours) and hospital stays (2.1 and 2.2 versus 4.5 days) were significantly lower for C-BPVP and S-BPVP by comparison to TURP. At 1, 3 and 6 months, statistically ameliorated IPSS and Qmax measurements were determined in the 2 bipolar vaporization series, while similar QoL and PVR values, PSA levels and postoperative prostate volumes were found in all 3 study arms.
CONCLUSIONS: The continuous plasma activation mode provided an average 20% and respectively 40% reduction in surgical time when compared to S-BPVP and TURP. Both C-BPVP and S-BPVP therapeutic alternatives emphasized superior perioperative safety and improved follow-up voiding and symptom score' parameters over TURP.
