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.
