Abstract
A 59-year-old man presented with lower abdominal pain. Plain X-ray of the urinary tract revealed radio-opaque shadows in the suprapubic region. Cystogram and intravenous urography showed these shadows in relation to the anterior part of the bladder. On cystoscopy, a small opening leading to a sac was seen. This was excised and stones were retrieved. The histology of the excised mucosa confirmed inflamed urachus. Four years later the patient remains asymptomatic.
