OBJECTIVES: A prospective randomized study was conducted to evaluate the safety and effectiveness of bipolar plasma vaporization with a novel electrode that produces vaporization of the tissue (transurethral vaporization of the prostate, TUVP) immersed in isotonic saline compared to the standard transurethral resection of the prostate (TURP) in the treatment of benign prostatic hyperplasia (BPH).
PATIENTS AND METHODS: From February 2009 to February 2010, 90 patients with BPH were randomized into two groups, and underwent conventional TURP (group 1) or TUVP (group 2) utilizing bipolar plasma vaporization with an innovative electrode (Olympus Winter & Ibe GmbH, Hamburg, Germany). International Prostate Symptom Scores (IPSS), transrectal ultrasonographic findings, maximal urine flow rates (Qmax), and postvoiding residual urine (PVRU) volumes of all cases were evaluated preoperatively and 1 month, 3 months, and 1 year postoperatively. Preoperative and postoperative serum hemoglobin, hematocrit and sodium concentrations of all patients were measured. All patients included in the study were monitored for 1 year.
RESULTS: In patients in group 1 (n = 47; mean age: 64.7 ± 7.3 years) TURP was performed. The patients in group 2 (n = 43; mean age: 65.4 ± 8.9 years) underwent bipolar TUVP. Cases in the two study groups matched for demographic characteristics and clinical parameters were assessed. The evaluation of IPSS scores, PVRU, Qmax, and prostatic volumes of the patients 1 month, 3 months, and 1 year postoperatively did not reveal any significant differences between the two groups. In group 2 (TUVP), postoperative catheter indwelling times were significantly shorter, and Na serum concentrations were also markedly lower (p < 0.005).
CONCLUSION: We detected similar effectiveness and morbidity rates in both groups. Bipolar TUVP has advantages such as shorter catheter indwelling times and hospital stays, and fewer bleeding episodes without any risk of transurethral resection syndrome. We believe that TUVP might be an alternative to TURP which is currently the 'gold standard' treatment in BPH.
