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

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.
