Additional Resources


- A posterior urethral valve is an obstructing membrane at the end of the bladder
- It is the most common cause of bladder outlet obstruction in male newborns (can't pee out amniotic fluid → oligohydramnios → Potter sequence)
- Potter sequence (oligohydramnios, limb/facial deformities, and pulmonary hypoplasia) due to lack of amniotic "cushion"
