Ectopic Pelvic Kidney With Urinary Tract Infection Presenting as Lower Abdominal Pain in a Child

Abstract

Ectopic pelvic kidney is a rare developmental anomaly. Ectopic pelvic kidney can present without the characteristic symptoms associated with the urinary tract pathology. Ectopic pelvic kidney is usually unknown, and nonspecific vague abdominal comfort maybe the only symptom. Early detection and recognition of an ectopic kidney can prevent long-term complications. We report a 3-year-5-month-old girl with ectopic pelvic kidney who experienced intermittent episodes of lower abdominal pain for about 1 month. Abdominal ultrasound, computed tomography, and intravenous pyelography demonstrated a pelvic kidney. Thereafter, the urinalysis showed pyuria (white blood cell 20/high power field), and urine culture grew Escherichia coli. We emphasize that pelvic kidney should be considered in patients presenting unexplained vague abdominal pain, especially in pediatric patients who had intermittent recurrent episodes.
