Purpose:
To explore the long-term clinical efficacy and safety of transurethral plasmakinetic resection of the prostate (PKRP) for benign prostatic hyperplasia (BPH).
Patients And Methods:
A total of 550 patients with BPH who had undergone PKRP from October 2006 to September 2009 were enrolled in this study. All patients were evaluated at baseline and follow-up (3, 12, 24, 36, 48, 60 months postoperatively) by peak flow rate (Qmax), postvoid residual (PVR), quality of life (QoL), International Prostate Symptom Score (IPSS), and Overactive Bladder Symptom Score (OABSS). Operative details and postoperative complications regarded as safety outcomes were documented.
Results:
A total of 467 patients completed the 5-year follow-up. The mean duration of surgery was 36.43 minutes, mean catheterization time was 48.81 hours, mean hospital stay was 4.21 days. At 60 months postoperatively, the mean Qmax increased from 6.94 mL/s at baseline to 19.28 mL/s, the mean PVR decreased from 126.33 mL to 10.45 mL, the mean IPSS score decreased from 15.79 to 7.51, the mean QoL score decreased from 4.36 to 1.91, and the mean OABSS score decreased from 6.39 to 3.65 (P < 0.001), respectively. In perioperative complications, the blood transfusion rate was 2.7%, urinary tract infection rate was 3.6%; no transurethral resection syndrome (TUR syndrome) occurred. In late complications, urethral stricture rate was 5.4%, recurrent bladder outlet obstruction rate was 2.1%, and the reoperation rate was 4.5%.
Conclusions:
PKRP is based on conventional monopolar transurethral resection of the prostate (TURP) and uses a bipolar plasmakinetic system. Our results indicate that the long-term clinical efficacy and safety of PKRP for BPH are remarkable. In particular, the incidence of urethral stricture, recurrent bladder outlet obstruction, and reoperation is low. We suggest that PKRP is a reliable minimally invasive technique that may be the preferred procedure for the treatment of patients with BPH.
