Bilateral ureteral duplication is a rare congenital genitourinary abnormality. Bilateral complete ureteral duplication is more common in females and all four ureters may open orthotopically on the bladder trigone. Ureteral duplication is often asymptomatic but may be associated with urinary tract infections or urolithiasis. Here we report a case of 51-year-old woman complaining of right-sided flank pain and fever was discovered on images to have bilateral complete ureteral duplication with one stone obstructing upper limb of the right double ureter. Images included abdominal plain radiography, intravenous pyelography, ultrasound, computed tomography and bilateral retrograde pyelograms. Escherichia coli was confirmed in urine culture. The impacted stone was completely cleared via ureteroscopy with intracorporeal lithotripsy.
