Abstract:
We report on a pediatric patient who was evaluated for recurrent episodes of urinary tract infection. Evaluation by IVP, cystography and retrograde ureteropyelography revealed a complete ureteral duplicity, grade II vesicoureteral reflux in the lower half of the left kidney and a blind bifid ureter arising at the distal third of the right ureter. This is an uncommon condition (about 150 cases have been reported) difficult to diagnose if undetected by conventional radiological evaluation and retrograde ureteropyelography may be required. It may be associated with urological or other types of malformations. It is generally asymptomatic and with scant consequences, thus treatment is initially conservative. Surgical excision of the blind bifid ureter is warranted only when complications present. In the present case, prophylactic antibiotic therapy was instituted. At one year follow up, the patient is asymptomatic and urine cultures are negative.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
