摘要： 目的探讨经尿道前列腺等离子电切术（PKVP）中保留膀胱颈完整性对低龄前列腺增生患者性功能及其生活质量的影
响。方法32例低龄前列腺增生症患者，平均55.4岁（50~60 岁）。采用Gyrus等离子系统行前列腺电切，术中注意保留膀胱颈
横行纤维肌肉区。术前和术后采用勃起功能国际问卷（IIEF-5）和生活质量评分表（QoL）评价患者勃起功能和生活质量，同时观
察随访患者有无逆行射精等。结果所有患者随访均超过6月，随访期间只有1例患者（3.13%）术后勃起功能异常；术后3个月5
例患者（15.6%）出现逆行射精，术后6个月有3例（9.4%）仍有逆行射精。结论PKVP术中注意保留膀胱颈，对低龄前列腺增生
症患者术后勃起功能有保护作用。

Abstract: Objective To explore the clinical value of preserving the integrity of the bladder neck in plasmakinetic vaporization
of the prostate (PKVP) in protecting the erectile function and improving the quality of life of patients with benign prostatic
hyperplasia (BPH) below 60 years of age. Methods Thirty-two patients with BPH, with a mean age of 55.4 years (range 50-60
years), were enrolled the study to undergo PKVP with Gyrus bipolar systems, in which the transverse fiber muscle area of the
bladder neck were carefully preserved. The erectile function and the quality of life of the patients were evaluated with the
International Index of Erectile Function (IIEF)-5 and Quality of Life (QoL) before and after the operation. Retrograde
ejaculation was also observed after the operation. Results In the 6-month follow-up, only 1 (3.13%) patient was found to have
erectile dysfunction. Five patients (15.6%) reported retrograde ejaculation 3 months after the surgery, and only 3 patients
(9.4%) had retrograde ejaculation at 6 months. Conclusion Preserving the bladder neck in PKVP may protect the erectile
function with BPH below 60 years of age.
