Posterior urethral valves presented at birth despite normal prenatal ultrasound scans.

摘要

Most patients with significant posterior urethral valves are identified antenatally. However, even with a normal antenatal ultrasound scan, posterior urethral valves may be detected after birth. We present a patient with significant upper urinary tract involvement identified 2 days after birth, despite a normal third-trimester antenatal ultrasound scan.
