Impact on sexual function of plasma button transurethral vapour enucleation versus plasmakinetic resection of the large prostate >90?ml: Results of a prospective, randomized trial

摘要

Abstract To compare the impact of plasma button transurethral vapour enucleation of the prostate (PVEP) and plasmakinetic resection of the prostate (PKRP) on lower urinary tract symptoms and sexual function in patients with benign prostatic enlargement (BPE) 90?ml. Between July 2017 and August 2018, 101 patients with symptomatic BPE were randomly, prospectively assigned to either PKRP or PVEP in our department. The clinical characteristics and sexual function were evaluated before and after surgery. Post‐void residual volume, IPSS and QoL were all significantly decreased compared with baseline data in each group, while Qmax was significantly increased. The IIEF‐5 score showed a slight but nonsignificant increase in both groups at 3 and 6?months after surgery, and there was no significant difference between the two groups. The post‐operative rate of reduced ejaculate volume was significantly higher than the pre‐operative rate in PKRP group, while there was no significant difference in PVEP group. PVEP had an attenuated effect on no ejaculate compared with PRKP, and they both had a significantly negative effect on no ejaculate. PVEP is an effective and minimally invasive procedure for large prostate. Compared with PKRP, PVEP has no effect on erectile dysfunction and has a lower negative impact on ejaculation.
