Combination of posterior urethral valves and urachus remnants has been described as rare occurrence. We report a case of a baby boy with normal antenatal scans, in whom the presence of large urachal cyst and posterior urethral valves causing high pressure bladder and chronic kidney disease was found. The patient underwent ablation of posterior urethral valves at 23 days of life and urachal cyst removal at age of 4 and a half months.
