Incidental diagnosis of a urachal stone in an asymptomatic patient: A rare case report.

Background: The urachus is a tubular remnant extending from the bladder to the umbilicus and consists of three layers. Urachal anomalies, such as patent urachus and urachal cyst, result from incomplete involution and are generally asymptomatic.

Methods: A 54-year-old man with a history of foul-smelling urine discharge from the umbilical region presented with renal colic symptoms. CT imaging incidentally revealed a 6 mm urachal stone. Urachal anomalies are rare and can lead to stone formation in adults due to prolonged urine stasis. Timely diagnosis with CT imaging can prevent complications such as stone formation.

Conclusions: Management of urachal anomalies typically involves surgical removal of the remnants to prevent future complications. Regular follow-up and appropriate treatment are crucial for alleviating symptoms and preventing complications.
