Blind-ending bifid and double ureters.

Bifid and double blind ureters are two rare congenital anomalies of the upper urinary tract. Usually they are incidental findings. Occasionally, they are associated with urinary tract infection, but the symptoms are not specific. The key to diagnosis is a careful urethral cystoscopy and retrograde pyelogram. Asymptomatic patients without urinary tract infection require no treatment. When symptoms or infection are present, excision of the blind branch is required with antireflux reimplantation of the normal ureter if needed.
