“…Calculus is also known to be seen in urachal remnant. Most reported cases are, however, seen in urachal cysts, 6 urachal xanthogranuloma, 5 or vesicourachal diverticulum. 7 Only one case of a patient with patent urachus passing a calculus from umbilicus has been reported 17 years ago.…”

The urachus is a fibrous remnant of the allantois, a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord. The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly. Failure of the inside of the urachus to be filled in leaves the urachus open, and four distinct types of urachal anomalies arise. In order of frequency, they are a patent urachus (50%), a urachal cyst (30%), an umbilical urachal sinus (15%), and a vesicourachal diverticulum. We are reporting here a case of a patent urachus containing calculus in a 45-year-old male patient, which is an extremely rare finding. The patient underwent exploratory laparotomy. Post-operative recovery of the patient was uneventful. This case was unusual in that the urachus contained a calculus, the patient was a young man who had never before shown any signs or symptoms of the condition or lower urinary track obstruction before this attack, and the calculus was near the vesical end of patent urachus.
