The blind-ending bifid ureter

A bifid blind-ending ureter is an extremely rare congenital anomaly of the upper urinary tract. This unusual ureteric condition appears to be more common in female subjects. Such patients may be asymptomatic or present with recurrent urinary tract infections, frequency, nycturia, abdominal pain or calculi. Asymptomatic patients without urinary tract infection require no treatment. When symptoms or infection are present, the treatment is surgical excision of the blind branch with antireflux reimplantation of the normal ureter. If hydronephrosis, pyonephrosis or renal damage is present, nephroureterectomy may be required.
