A Rare Case of Urachal Remnant with Calculus Just Above the Bladder

The urachus closes naturally after birth. Its opening leads to anomalies in which secondary complications, including urachus calculi, may be formed. This disease is often discovered incidentally in radiographic examinations and is rare in adults. The purpose of this study is to present a rare case of urachus calculus in an adult located precisely in the anterior wall of the bladder, at the junction of the bladder and urachus. Our case was a 38-year-old man with complaints of abdominal pain. The computerized tomography (CT) scan images showed a calculus attached to the anterior and inner wall of the bladder in inserting the urachus into the bladder. Cystoscopy showed the calculus is connected to the urachus duct without any mass/tumor. The collection of evidence suggests a calcified urachus. The patient was discharged with conservative treatment and a mild analgesic.
