A Self-Induced Foreign Body in the Urinary Bladder of an Adolescent Female.

ABSTRACT

In the pediatric population, foreign bodies within the urinary bladder are uncommon, typically resulting from urethral insertion out of curiosity. Other etiologies include sexual assault, iatrogenic factors, or migration from adjacent sites. Symptoms such as urinary retention, dysuria, increased frequency, decreased volume, nocturia, hematuria, painful erections, and pelvic pain are common. Radiographic imaging in the form of pelvic X-rays, ultrasound and CT scans often aids in diagnosis and making an action plan. Management depends on the object type, size, location and available expertise, often starting with a transurethral approach and resorting to open surgery if necessary. This case report describes a 13-year-old female presenting with severe dysuria and visible hematuria. Initially reporting the accidental insertion of a scarf pin into her vagina, she later admitted to intentionally inserting it. A pelvic radiograph revealed a needle-like object in the pelvis but its location and position were more convincing of its presence in the urinary bladder. A diagnostic cystoscopy was performed which confirmed a scarf pin in the urinary bladder, embedded in its wall. The pin was successfully removed transurethrally using endoscopic forceps.
