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

ABSTRACT

OBJECTIVE: To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasmakinetic technique (PKRP) in the treatment of benign prostate hyperplasia (BPH). METHODS: 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. RESULTS: 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 (P < 0.01). CONCLUSION: Transurethral prostatectomy with the bipolar plasmakinetic technique is a safe and effective means for the treatment of BPH.
