[Influence of photoselective vaporization of prostate on erectile function in patients with benign prostatic hyperplasia].
OBJECTIVE
To assess the influence of photoselective vaporization of the prostate (PVP) on the erectile function of the patient with benign prostatic hyperplasia (BPH).


METHODS
Using IIEF-5, we conducted a questionnaire investigation among 210 BPH patients before and after treated by PVP (n = 80) and transurethral resection of the prostate (TURP, n = 130). We also reviewed the clinical data and compared the pre- and post-operative penile erectile function between the two groups of patients.


RESULTS
Follow-up was completed in 76 cases of PVP and 123 of TURP. The baseline data showed no statistically significant differences between the two groups in age, prostate volume, IPSS, QOL, Qmax, post void urine residual volume and IIEF-5 scores (P>0.05). Compared with the IEFF-5 score at the baseline (21.88 +/- 2.46), those at 3, 6 and 12 months after PVP were 16.72 +/- 3.17, 19.34 +/- 2.46 and 19.29 +/- 2. 18, respectively, significantly decreased at 3 months (P = 0.042), but with no remarkable difference at 6 and 12 months (P >0.05). Nor were there significant differences in the IIEF-5 score between the PVP and TURP groups at any time points (P>0.05). At 6 months after surgery, the incidence rates of erectile dysfunction were 11.7% and 13.7% in the TURP and PVP groups, respectively (P>0.05).


CONCLUSIONS
PVP may reduce erectile function in some cases in the early stage after surgery, but this adverse effect does not last long and is basically similar to that of TURP.
