Introduction and Objectives 

After transurethral prostatectomy, erectile dysfunction and ejaculatory dysfunction are significant concerns for patients. We compared ejaculatory hood-sparing technique in patients who underwent photoselective vaporization of the prostate using the GreenLight Laser (EjS-PVP) with the ejaculatory hood-sparing technique in patients who underwent bipolar button plasma vaporization of the prostate (EjS-BPVP) in the surgical management of benign prostatic hyperplasia (BPH).

Materials and Methods 

Twenty-seven patients were randomized to either undergo EjS-PVP or EjS-BPVP from August 2016 to March 2018. All of the patients were sexually active with antegrade ejaculation before prostatectomy. We evaluated International Prostate Symptom Score (IPSS), quality of life (QoL), peak flow rate (Qmax), postvoid residual volume (PVR), International Index of Erectile Function and ejaculatory function by the Male Sexual Health Questionnaire (MSHQ). Men were evaluated preoperatively and at 1, 3, and 6 months postoperatively. The primary outcome was ejaculation preservation measured as no change or preservation in antegrade ejaculate at the last follow-up visit by MSHQ (6 months).

Results

Twenty-seven patients with a mean age of 65.6 ± 8.4 years underwent either EjS-BPVP or EjS-PVP. There were no differences in baseline characteristics between the two groups. Improvements in IPSS, QoL, Qmax, and PVR were durable throughout the study period in both groups. There was no difference in outcomes between groups. Postoperatively, there was no change in ejaculatory function with EjS-BPVP utilizing either 180 W EjS-PVP or bipolar energy. The change in MSHQ Ejaculation Scale was −2.1 and −5.4 at 6 months in both arms. The 6-month ejaculatory preservation rate was 85% in the EjS-PVP group and 78% in the EjS-BPVP group.

Conclusions

EjS GreenLight photoselective vaporization and bipolar plasma button vaporization is a safe and effective method for treating men with lower urinary tract symptoms secondary to BPH with maintenance of antegrade ejaculation.
