The epidemiology of genitourinary foreign bodies (GUFB) has been mainly described through case reports and small series. The aim of this study is to investigate the epidemiologic, medical, and socioeconomic factors associated with GUFB, along with the resultant costs of care in emergency departments (EDs) nationwide. ED visits with the primary diagnosis of a GUFB between 2010 and 2014 were abstracted from the Nationwide Emergency Department Sample database. Between 2010 and 2014, a weighted estimate of 102,333 visits to the ED with GUFB were recorded in the US, representing a national incidence of 7.6 ED visits per 100,000 persons. Of these visits, 4.7% resulted in admission and males were more likely to be admitted (24.8% vs. 2.1%, p < 0.01). A third of patients had low income, 30% had no medical insurance, and a third of patients had Medicaid. Urethra/bladder and penile foreign bodies had a significant association with mental health disorders (35.6%). Vulvar/vaginal foreign bodies had a lower prevalence of mental health disorders (6.1%). Costs of managing patients in the ED averaged $3769. More importantly, penile or urethra/bladder foreign bodies incurred a higher cost ($30,071). This is the largest population-based study investigating the epidemiology of GUFB. GUFB are more common in young women and the majority of them are vulvar/vaginal. Urethral and bladder foreign bodies occurred in older male patients and are associated with longer hospital stays and costs. Over one third of male patients with urethra/bladder had significant mental health disorders.

泌尿生殖系统异物（GUFB）的流行病学主要通过病例报告和小编进行了描述。这项研究的目的是调查与GUFB相关的流行病学，医学和社会经济因素，以及全国范围内急诊室（ED）产生的护理费用。急诊科就诊于2010年至2014年期间对GUFB进行了初步诊断，摘录自全国急诊科样本数据库。在2010年至2014年之间，美国记录了通过GUFB进行的ED访视的加权估计数102,333次，这表示全国的发病率是每100,000人7.6例ED访视。在这些访问中，有4.7％的人被录取，而男性更容易被录取（24.8％对2.1％，p <0.01）。三分之一的患者收入较低，30％的患者没有医疗保险，三分之一的患者有医疗补助。尿道/膀胱和阴茎异物与精神健康障碍有显着关联（35.6％）。外阴/阴道异物的心理健康障碍患病率较低（6.1％）。急诊部的患者平均管理费用为3769美元。更重要的是，阴茎或尿道/膀胱异物产生的费用更高（30,071美元）。这是调查GUFB流行病学的最大的基于人群的研究。GUFB在年轻女性中更为常见，其中大多数是外阴/阴道。尿道和膀胱异物发生在老年男性患者中，并与更长的住院时间和费用相关。超过三分之一的男性尿道/膀胱患者患有严重的精神疾病。
