There is little reported on sexual functional outcome following photoselective vaporisation of the prostate using the 120 W lithium triborate laser.
The objective of this study was to evaluate changes in sexual function at 3 and 12 months following PVP.
The primary outcome measures were changes in voiding parameters and changes in erectile function in the international index of erectile function (IIEF-5). Change in erectile function was defined as mild (<5 IIEF points) or major (≥5 points).
Results found that 75% of men had an IIEF-5 < 17 at baseline. At 3 months, the mean post-operative IIEF-5 score was unchanged compared to baseline (P = 0.13). A major decline in erectile function was seen in 12.4 and 24% of men at 3 and 12 months, respectively, and a major improvement in erectile function was seen in 8.3 and 6% at 3 and 12 months, respectively. There was no correlation in change in erectile function with urinary function, quality of life and loss of emission on orgasm. Loss of emission on orgasm was reported in 65% of respondents.
Significant changes in erectile function are observed following PVP although a cause and effect relationship remains unclear.
使用 120W 硼酸三锂激光进行前列腺光选择性汽化术(PVP)后,关于性功能结局的报道很少。
本研究旨在评估 PVP 后 3 个月和 12 个月时性功能的变化。
主要结局测量指标为国际勃起功能指数(IIEF-5)中排尿参数和勃起功能的变化。勃起功能的变化定义为轻度(<5 个 IIEF 点)或重度(≥5 个点)。
结果发现,75%的男性在基线时 IIEF-5<17。术后 3 个月,与基线相比,平均 IIEF-5 评分无变化(P=0.13)。3 个月和 12 个月时,分别有 12.4%和 24%的男性出现勃起功能明显下降,分别有 8.3%和 6%的男性出现勃起功能明显改善。勃起功能的变化与尿功能、生活质量和射精丧失无关。65%的受访者报告射精丧失。
尽管因果关系尚不清楚,但 PVP 后会观察到勃起功能的显著变化。
