Vesicourachal diverticulum with calculus in a recurrent stone former: A rare entity

Abstract

The urachus is a tubular embryonic structure connecting the allantois at the umbilicus to the bladder. It gets obliterated and remains as median umbilical ligament. Partial or complete failure of this process results in urachal anomalies. We are reporting a rare case of 54 year male patient presenting with obstructive lower urinary tract symptoms and history of spontaneous passage of stones in urine and on evaluation found to have vesicourachal diverticulum with calculus in it.
