title: Transurethral resection of the prostate with a bipolar tissue management system compared to conventional monopolar resectoscope: one-year outcome.
abstract: The purpose of the present study was to evaluate the efficacy and safety of bipolar transurethral prostatectomy (TURP) using the Gyrus PlasmaKinetic System compared with conventional monopolar TURP. This study included 102 patients with benign prostatic hyperplasia (BPH) who underwent TURP from January 2003 to March 2005. In all, 49 consecutive patients had bipolar and 53 had monopolar TURP. All patients were assessed by preoperative and postoperative International Prostate Symptom Score (IPSS), uroflowmetry, transrectal ultrasonography, operative time, weight of resected tissue, change in serum sodium and hemoglobin, duration of catheter use, length of hospital stay, and complication rates. Significant improvement was seen postoperatively in both groups, and no difference was observed in the resection time, weight of resected tissue, change in serum sodium and hemoglobin, improvement of IPSS and peak flow rate (Qmax), or complication rates over the 12-month follow-up in both groups. There was, however, a significant difference in duration of catheter use and hospital stay. Duration of catheter use (2.28 days vs. 3.12 days) and hospital stay (3.52 days vs. 4.27 days) were shorter in the bipolar group (p = 0.012 vs. p = 0.034, respectively). Our results demonstrate that bipolar TURP using the Gyrus Plasma Kinetic System is as effective as conventional monopolar TURP with the additional advantage of reduced length of catheter use and hospital stay. Bipolar TURP is a promising new technique that may prove to be a good alternative to conventional TURP in the future.
