A Case Report of Patent Urachus With Perinatal Cardiac Abnormality.

Patent urachus is a rare urachal anomaly. This case involves a newborn female with a cyst near the umbilicus and a small patent ductus arteriosus with left-to-right shunting. A low-dose fluoroscopic cystogram revealed contrast entering a tubular structure extending from the bladder to the umbilicus, with evidence of leakage at the umbilical site, confirming a patent urachus. Surgical treatment was performed through an infraumbilical incision to remove the persistent urachus up to the bladder. The patient recovered well postoperatively and was discharged in stable condition to her parents' care. Early diagnosis and management are essential for favorable outcomes in such anomalies.
