title: [Protective effect of preserving bladder neck integrity on erectile function in patients undergoing plasmakinetic vaporization for benign prostatic hyperplasia].
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.
  
  
  CONCLUSIONS
  Preserving the bladder neck in PKVP may protect the erectile function with BPH below 60 years of age.
