Introduction: The epidemiology of genito-urinary foreign bodies (GUFB) has been mainly reported through case reports and small series. The aim of this study is to investigate the epidemiology, the medical-socio-economic factors associated with GUFB and the cost in the United States emergency room setting.
Methods: Emergency Department (ED) visits with the primary diagnosis of a genito-urinary foreign body (based on ICD-9 codes 939.0-939.9) between 2010-2014 were abstracted from the Nationwide Emergency Department Sample database.
Results: Between 2010 and 2014, a weighted estimate of 120,223 visits to the ED with GUFB were recorded in the US, representing a national incidence of 7.6 ED visits per 100,000 persons. 4.68% of ED visits resulted in admissions 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 when compared to vulvar/vaginal foreign bodies (35.6% vs. 6.1%, p < 0.001). Costs of managing patients in the ED averaged $3,769. More importantly, penile or urethra/bladder foreign bodies incurred a higher cost ($30,071).
Conclusions: This is the largest population-based study investigating the epidemiology of genito-urinary foreign bodies, which occurs at a higher incidence than expected. GUFB are more common in young women and the majority of them are vulvar/vaginal. Penile and urethral/bladder foreign bodies occurred in older male patients and are associated with longer hospital stays and costs. Mental health disorders were more common in male patients and in cases of urethral/bladder foreign bodies.
