BackgroundUrethral foreign bodies (UFBs) are rare in pediatric emergency care, but require immediate diagnosis and intervention when they occur. Although radiography, computed tomography, and cystography are available for diagnosing UFBs, these modalities are undesirable because they involve radiation exposure. Point-of-care ultrasound (POCUS) is used as an alternative imaging modality for UFB detection in adult patients, but reports of its use in pediatric emergency departments are still scarce. We report a pediatric case of a UFB detected by POCUS.Case ReportA 10-year-old boy with a history of a learning disorder presented to our pediatric emergency department with a paper clip in his penis, which he had intentionally inserted during play. He denied any symptoms, such as abdominal pain, vomiting, and hematuria. Physical examination failed to reveal the tip of the FB, but showed a palpable mass in the penile urethra accompanied by mild tenderness in the area. POCUS demonstrated a hyperechoic structure with reverberation artifact extending to the bulbar urethra. Endoscopic removal was planned, but the tip of the FB emerged from the external urethral meatus with postural change. Manual removal was successfully performed, after which the hyperechoic structure in the urethra was no longer visible on ultrasonography. The patient was discharged on the same day of the procedure. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: POCUS is a noninvasive procedure that can be useful for detecting UFBs in children.Copyright © 2021 Elsevier Ltd. All rights reserved.
