Transurethral resection of prostate: technical progress by bipolar Gyrus plasma-kinetic tissue management system.

ABSTRACT

AIM: We report our experience about bipolar plasma-kinetic resection of the prostate for the treatment of bladder outlet obstruction due to benign prostatic hyperplasia (BPH), considering intraoperative variables and short-term METHODS: Three hundred and eighty-nine patients affected by symptomatic BPH, underwent transurethral resection of prostate using the bipolar plasma-kinetic technique from Decem-ber 2001 to July 2004 in a prospective fashion. Bipolar resections of the prostate were performed using Plasma-Kinetic Tissue Management System (Gyrus Medical Ltd., UK). Preoperative, digital rectal examination, haemoglobin level, total PSA, transrectal ultrasound, International-Prostate Symptom Score (I-PSS) and uroflowmetry parameters were recorded. Patients were assessed for safety and efficacy, evaluating intraoperative and postoperative complications and measuring both the IPSS and the maximum flow rates (Qmax) after 12 months. RESULTS: The mean operative time was 89 min (range 48-121 min); the mean prostatic resected weight (measured by an electronic scales) was 49.6 g (3267 g). The mean decrease of haemoglobin level was 1.1 g/dL (range 0.5-1.9), with a mean catheterization time of 1.3 days (range 1-5). Qmax increase ranged from 120 to 230% (mean 190%) 12 months after surgery. Correspondingly, IPSS decrease ranged from 48% to 86% (mean 79%). Postoperative acute urinary retention, urethral strictures, bladder neck sclerosis and urinary incontinence were recorded in 1.57%, 2.57%, 1.28% and 0.77%, respective. CONCLUSION: The transurethral resection of prostate using a bipolar plasma-kinetic device represent a safe and effective option for the treatment of symptomatic BPH.
