A Rare Cause of Anuria: A Case of Inflammatory Iliac Aneurysm

Abstract

The patient was a 68-year-old male. The patient of complaint was anuria. There was no sense of urination. Abdominopelvic ultrasonography(USG) and abdominopelvic computed tomography (CT) without contrast revealed an empty bladder and the presence of bilateralhydroureteronephrosis. Aneurysms in the aorta and bilateral iliac arteries were detected. It caused bilateral hydroureteronephrosis viacompressing “aneurysmal bilateral ureter”. Creatinine was 4.97 mg/dL, BUN 37 mg/dL, C reactive protein (CRP) 193 mg/L and erythrocytesedimentation rate (ESR) 99 mm/h. A double J stent was inserted on the right and a nephrostomy tube was placed on the left. The ureaand creatinine levels returned to normal postoperatively. Urinary obstruction or anuria can develop due to a lot of reasons such asstricture, urolithiasis, clot, and malignancy or inflammation of peripheral organs and etc. Abdominal aortic aneurysm (AAA) or iliacartery aneurysm (IAA) is a very rare cause of urinary obstruction or anuria. Abdominal aortic aneurysm (AAA) and iliac artery aneurysm(IAA) are rare factors that can cause urological symptoms with an inflammatory or direct compressive effect. There have been very rarelyreported as a cause of acute anuria. We present a case of acute anuria due to bilateral inflammatory iliac artery aneurysm.
