[Therapeutic efficacy of bipolar plasmakinetic technique compared with transurethral resection on benign prostate...

To evaluate the effect and safety of transurethral prostatectomy with the bipolar plasmakinetic technique (PKRP) compared with the transurethral resection (TURP) in the treatment of benign prostate hyperplasia (BPH).

Four hundred BPH patients with matched lesions were divided into 2 groups: 200 patients, aged 74.1 (58-91), underwent transurethral prostatectomy with PKRP, and 200 patients, aged 73.8 (56-90), underwent TURP.

In the PKRP group the average IPSS decreased from 27.1 +/- 4.5 preoperatively to 11.3 +/- 3.4 postoperatively 6 months after (P < 0.01), the. average maximum flow-rate Q (max) increased from 6.1 +/- 2.4 ml/s preoperatively to 18.6 +/- 3.5 ml/s postoperatively (P < 0.01), and the average residual urine (RU) reduced from 102.3 +/- 43.3 ml preoperatively to 22.6 +/- 16.3 ml after the operation (P < 0.01). However in the TURP group the average IPSS decreased from 26.9 +/- 4.2 preoperatively to 10.8 +/- 3.6 6 months after the operation (P < 0.01), the Q (max) increased from 5.7 +/- 2.4 ml/s preoperatively to 19.1 +/- 3.7 ml/s postoperatively (P < 0.01), and the average RU decreased from 102.3 +/- 43.3 ml preoperatively to 22.6 +/- 16.3 ml after the operation (P < 0.01). There were no significant differences in these parameters between these 2 groups (all P > 0.05). The average catheter retention time was 31.5 h in the PKRP, significantly shorter than that in the TURP group (61.5 hours, P < 0.01). The incidence rate of post-operational asynodia in the PKRP group was 14.3%, not significantly different from that in the TURP group (15.2%, P > 0.05). During the operation no hemorrhage or transurethral resection syndrome (TURS) occurred in the PKRP group, however, there were 5 cases of TURS and 18 cases of blood transfusion in the TURP group.

PKRP has the same therapeutic efficacy as TURP on BPH. Moreover, it was more cheaper and with lower complication than TURP.
