Bilateral Ureteral Obstruction in Children With Ulcerative Colitis and Oliguria: When and Why?

TL;DR

A 12-year-old boy with ulcerative colitis developed sudden kidney issues due to a rare urinary blockage, highlighting the need for quick diagnosis.

Contribution

This case report highlights the rare occurrence of bilateral ureteral obstruction in a pediatric UC patient.

Findings

Bilateral ureterovesical junction obstruction was detected in a child with ulcerative colitis.

Fracture-prone calculi were found in edematous ureteral orifices during cystoscopy.

Sudden oliguria in UC patients may indicate obstructive uropathy requiring urgent intervention.

Abstract

Inflammatory bowel disease (IBD) is an inflammatory clinical entity with many extraintestinal symptoms, including urinary tract manifestations. However, the bilateral ureteral obstruction is extremely rare. We report a case of bilateral ureteral obstruction in a 12-year-old male patient with ulcerative colitis (UC). Ultrasonography in the context of sudden anuria revealed bilateral ureterovesical junction (UVJ) obstruction, and the following cystoscopy verified the presence of fragile calculi in both edematous ureteral orifices. The literature data on UC in the pediatric population are scarce. Sudden deteriorating oliguria in an UC patient may result from secondary obstructive uropathy. Immediate diagnosis and treatment are essential to prevent acute kidney injury.
