Ureteral obstruction by an aberrant renal artery: A case report

The ureter is a muscular tubular structure that carries urine from the kidney to the urinary bladder. It is usually about 20–25 cmin length and 3–5 mm diameter. The upper half lies in the belly and the lower half in the pelvic area. A ureteral obstruction is ablockage of either unilateral or bilateral ureters that carry urine from the kidneys to the urinary bladder. Ureteral obstruction canbe curable. However, if it is not treated, symptoms can quickly move from mild pain, fever, and infection to severe including lossof kidney function, sepsis, and death. Here, we report the case of an upper ureteral obstruction by an aberrant artery. The arterywas originating from the right renal artery, supplying the right psoas muscle, and causing gross proximal hydroureteronephrosisin a 24-year-old male patient. The patient was diagnosed using contrast-enhanced computed tomography through the abdomenexamination.
