Congenital Meatal Stenosis

The failed regression of the distal urethral membrane causes symptoms of subvesical obstruction or recurrent urinary tract infections. The distal urethral membrane is the junction between externally ingrowing ectodermal glans tissue and entodermal urethral mucosa, originating from the urogenital sinus.

Bougies can be used to objectify the width of the lumen. Treatment consists of a ventral incision of the membrane with a good prognosis. The differentiation from the acquired meatus stenosis is therapeutically important since the surgical treatment is more complex, and recurrence is likely.
