Posterior urethral valves presenting as abdominal distension and undifferentiated shock in a neonate: the role of screening emergency physician-directed bedside ultrasound.

We present a case of shock in a 7-week-old neonate with obstructive uropathy secondary to posterior urethral valves (PUV). The antenatal ultrasound and the 2-week maintenance visit were unremarkable. A screening emergency physician directed bedside ultrasound (SEPUS) served to rapidly establish the diagnosis, initiate appropriate management, and facilitate early relief of urinary obstruction. We discuss the potential role of SEPUS in a critically ill neonate and briefly review the management of PUV.
