RESUMEN
OBJECTIVE: To investigate the influence of plasmakinetic energy transurethral resection of the prostate (PKRP) versus that of transurethral bipolar plasmakinetic enucleation and resection of the prostate (PKERP) on the bladder function, sexual function and incidence of complications in BPH patients with the prostate volume <100 ml. METHODS: We randomly assigned 140 BPH patients with the prostate volume <100 ml to receive PKRP (n = 70) or PKERP (n = 70) in our hospital from July 2013 to July 2015. We compared the maximum urinary flow rate (Qmax), residual urine volume (RUV), and the rates of ED and retrograde ejaculation before and after surgery as well as the incidence of postoperative complications between the two groups of patients. RESULTS: The Qmax and RUV of the patients were (25.11 ± 7.12) ml/s and (4.06 ± 1.74) ml in the PKERP group postoperatively, significantly improved as compared with the baseline (ï¼»8.60 ± 2.33ï¼½ ml/s and ï¼»66.85 ± 14.33ï¼½ ml, P < 0.05), and even better than (18.87 ± 4.07) ml/s and (9.45 ± 2.66) ml in the PKRP group (P < 0.05). The incidence rates of ED and retrograde ejaculation were 61.43% and 28.57% in the PKRP group, significantly higher than in the PKERP group (40.00% and 14.29%) (P < 0.05) and the baseline (35.71% and 10.00%) (P < 0.05). The postoperative incidence rate of transient urinary incontinence was remarkably higher in the PKERP than in the PKRP group (22.86% vs 8.57%, P < 0.05). There were no statistically significant differences between the two groups in the incidence rates of secondary hemorrhage, urethral injury, or genuine urinary incontinence after operation (P > 0.05). CONCLUSIONS: Compared with PKRP, PKERP can effectively improve the clinical symptoms and signs and protect the bladder function of the BPH patients with the prostate volume <100 ml, but may increase the risk of transient urinary incontinence.
