[Transurethral prostatectomy with the bipolar plasma kinetic technique for benign prostate hyperplasia: a report of 297 cases].

ABSTRACT

OBJECTIVE: To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasma kinetic technique (PKRP) in the treatment of benign prostate hyperplasia(BPH). METHODS: Two hundred and ninty-seven BPH patients underwent transurethral prostatectomy with the bipolar plasma kinetic technique. The preoperative estimated weight of the prostate ranged from 35 g to 102 g, averaging 52 g. RESULTS: The operation lasted 40 approximately 65 min, averaging 51 min. The resected tissues weighed 40 approximately 80 g, averaging 46 g. During the operation no transurethral resection (TUR) syndrome occurred. The catheter was removed 4 approximately 5 days after the operation, all with fluent urination. The patients were followed up for 2 approximately 33 months. IPSS decreased from average 31.5 preoperatively to average 6.8 postoperatively (P < 0.001). Average maximum flow-rate (Q(max)) decreased from 6.3 ml/s preoperatively to 18.6 ml/ s postoperatively (P < 0.001). Preoperative average residual urine was 97 ml and reduced to average 9 ml after the operation. Temporary incontinence occurred in 4 cases, perioperative hemorrhage in 2, and urethral stricture in 1. CONCLUSION: Transurethral prostatectomy with the bipolar plasma kinetic technique is a safe and effective means for the treatment of BPH.
