[Transurethral prostatectomy with the bipolar plasmakinetic technique for benign prostate hyperplasia: a report of 712 cases]

To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasmakinetic technique (PKRP) in the treatment of benign prostate hyperplasia (BPH).A total of 712 BPH patients underwent transurethral prostatectomy with the bipolar plasmakinetic technique. The patients averaged 70.6 years of age and 52 g (range 35-102 g) in estimated prostate weight preoperatively. Comparative analyses were made on the maximum urine flow rate (Qmax), residual urine volume and scores on IPSS and QOL obtained pre- and post-operatively.The operations lasted 20-120 minutes (mean 51 min), the resected tissues weighed 15-96 g (mean 46 g), and no transurethral resection syndrome (TURS) occurred. The catheters were removed 4 -5 days after surgery. The patients were followed up for 1 -52 months (mean 27.6 mo). Obvious reduction was observed in the average Qmax from 4.7 ml/s preoperatively to 19. 1 ml/s postoperatively, in the mean IPSS score from 26.6 to 5. 8, and in the mean QOL score from 5.4 to 1.7, all with significant differences (P0.01).Transurethral prostatectomy with the bipolar plasmakinetic technique is a safe and effective means for the treatment of BPH.
