Prenatal sonographic diagnosis of posterior urethral valves: identification of valves and thickening of the posterior urethral wall.
This report describes 2 heretofore unreported sonographic findings that may aid in the antenatal diagnosis of posterior urethral valves. Each of 2 fetuses showed a prominent or thickened posterior urethra and one or more bright echogenic lines representing valve tissue within a dilated and/or thickened posterior urethra. These findings helped solidify the antenatally suspected diagnosis of posterior urethral valves. The diagnosis was confirmed clinically and surgically during neonatal life. These 2 imaging findings may help in providing a more definitive antenatal diagnosis of posterior urethral valves and allow more expeditious therapy.
