Management of genitourinary foreign bodies in a predominantly incarcerated population

INTRODUCTION Genitourinary foreign body (FB) insertion is a rare occurrence. Commonly reported reasons for insertion include autoeroticism and intoxication, however psychiatric illness is thought to contribute in most cases. In the incarcerated population, malingering plays a prominent role. We examined clinical patient characteristics and management patterns for cases of genitourinary FB insertion and sought to identify risk factors for recidivism.

A retrospective review was performed of all patients presenting to a tertiary trauma center with a genitourinary FB between January 2001-June 2019. Patient demographics, presentation, work up, and management were reviewed. Bivariate and multivariate statistical analyses were performed.

Patients were primarily young (33 yo, range: 21-93), male (92%), incarcerated (67%), and had at least one psychiatric diagnosis (71%). Concomitant FB ingestion was present in 56 (41.5) encounters. Risk factors for repeat FB insertion included incarceration (100.0% versus 51.5%, p = < 0.01), psychiatric comorbidity (100.0% versus 51.5%, p = < 0.01), and other concomitant FB insertion/ingestion (68.7% versus 18.2%, p = < 0.01). Common methods of FB extraction included flexible cystoscopy (33.8%), extrinsic pressure (21.0%), rigid cystoscopy (12.8%), and open surgery (8.1%). Fifty-three (39.2%) encounters required anesthesia and 64 (47.4%) encounters required admission.

Genitourinary FBs are usually removed via endoscopic or minimally invasive extraction techniques and the majority are located within the anterior urethra. Special consideration should be given to patients with psychiatric comorbidity, concomitant FB insertion/ingestion, or those presenting from a correctional facility as these characteristics are associated with repeat insertion attempts.
