In a large-scale epidemiology study, 50% of aging men reported erectile dysfunction (ED) or ejaculatory dysfunction (EjD), with lower urinary tract symptoms (LUTS) an independent risk factor for each of these conditions. In light of the shift from urologists (UROs) to primary care/internal medicine physicians (PCPs) for the initial management of men with LUTS associated with benign prostatic hyperplasia (BPH), a survey was conducted to assess the perceptions of UROs and PCPs regarding sexual dysfunction (SD) in men with LUTS/BPH and the effects of BPH treatments (alpha(1)-adrenergic receptor antagonists (alpha-blockers) and 5alpha-reductase inhibitors (5ARIs)) on sexual function. The survey was mailed to 7500 UROs and 2500 PCPs, with 1275 (13%) surveys returned (1087 by UROs, 177 by PCPs and 11 by other specialty). Alpha-blocker monotherapy was the most common medication prescribed by both UROs (56%) and PCPs (47%). UROs estimated that 19% of their patients with LUTS/BPH experienced SD owing to their symptoms compared with the estimate of 27% by PCPs. UROs estimated that 19% of their patients experienced SD owing to their BPH medication compared with the PCP estimate of 24%. The incidence of EjD owing to BPH medications estimated by UROs (32%) was higher than that estimated by PCPs (22%); the rate of ED estimated by PCPs (34%) was higher than that estimated by UROs (23%). UROs were more aware than PCPs of the specific sexual side effects caused by alpha-blockers versus 5ARIs. These results suggest that physicians are underestimating the prevalence of SD in men with LUTS/BPH. As men with LUTS/BPH are at increased risk for SD, physicians should be especially cognizant of BPH treatment-related sexual side effects.
在一项大规模流行病学研究中,50%的老年男性报告有勃起功能障碍(ED)或射精功能障碍(EjD),下尿路症状(LUTS)是这些病症各自的独立危险因素。鉴于对于伴有良性前列腺增生(BPH)的LUTS男性患者的初始管理已从泌尿科医生(UROs)转向初级保健/内科医生(PCPs),开展了一项调查,以评估UROs和PCPs对LUTS/BPH男性患者性功能障碍(SD)的看法以及BPH治疗(α1肾上腺素能受体拮抗剂(α阻滞剂)和5α还原酶抑制剂(5ARIs))对性功能的影响。该调查问卷被邮寄给7500名UROs和2500名PCPs,共收回1275份(13%)调查问卷(UROs收回1087份,PCPs收回177份,其他专科收回11份)。α阻滞剂单药治疗是UROs(56%)和PCPs(47%)最常开具的药物。UROs估计,其LUTS/BPH患者中有19%因症状而出现SD,而PCPs的估计值为27%。UROs估计,其患者中有19%因BPH药物治疗而出现SD,而PCPs的估计值为24%。UROs估计因BPH药物导致的EjD发生率(32%)高于PCPs的估计值(22%);PCPs估计的ED发生率(34%)高于UROs的估计值(23%)。与5ARIs相比,UROs比PCPs更了解α阻滞剂引起的特定性副作用。这些结果表明,医生低估了LUTS/BPH男性患者中SD的患病率。由于LUTS/BPH男性患者发生SD的风险增加,医生应特别注意BPH治疗相关的性副作用。
