In recent years, holmium laser enucleation of the prostate (HoLEP) and thulium laser enucleation of the prostate (ThuLEP) have been widely used in the treatment of benign prostatic hyperplasia (BPH) because of their significant clinical effects, high safety, and low incidence of complications. With the improvement of living standards, BPH patients care about not only the improvement of lower-urinary-tract symptoms (LUTS) secondary to BPH but also that of sexual function, especially erectile function, after treatment. However, there are comparatively few studies about the effects of HoLEP and ThuLEP on erectile function and relevant opinions are quite controversial. Most studies reported that HoLEP and ThuLEP did not impair erectile function, but some showed that a few patients experienced a decrease of erectile function after operation. Before surgery, urologists should explain clearly to the patients the potential impact on sexual function, as mental factors may also induce erectile dysfunction. This study presents an overview of recent studies about the infuence of HoLEP and ThuLEP on erectile function.
近年来钬激光与铥激光前列腺剜除术被广泛地应用于临床，其显著的疗效、较好的安全性以及较低的并发症发生率均已被证实。随着生活水平的提高，患者对于BPH的治疗已经不仅仅满足于下尿路症状的改善。这两种术式对男性性功能尤其是勃起功能的影响越来越受到重视，而相关研究并不是很多，且不同的研究之间也存在着一定的争议。大部分观点认为，这两种术式不影响患者勃起功能。也有一些研究表明少数患者术前勃起功能正常，术后出现了一定程度的勃起功能下降。虽然患者对勃起功能障碍的关注不多，但是心理因素也可能是影响勃起功能的一个重要因素，术前应当和患者充分沟通，了解手术对性功能产生不良影响的风险程度。本文就近年来发表的有关钬激光与铥激光前列腺剜除术对勃起功能影响的文献做一综述。.
