Congenital Anterior Urethral Diverticulum in Identical Twins

Congenital anterior urethral diverticulum (CAUD) is an uncommon abnormality of the male urethra. In the literature, cases of CAUD affecting both children within a set of identical twins or presenting concomitantly with another urethral condition are exceedingly rare. We describe 2 cases of CAUD in i...

Description
Summary:Congenital anterior urethral diverticulum (CAUD) is an uncommon abnormality of the male urethra. In the literature, cases of CAUD affecting both children within a set of identical twins or presenting concomitantly with another urethral condition are exceedingly rare. We describe 2 cases of CAUD in identical twins: a pair of newborns in which Twin 1A and Twin 1B both present with CAUD, and a second pair of newborns in which only Twin 2A presents with CAUD along with a partial collateral urethral duplication. In doing so, we aim to add to the incomplete literature on the embryological development of CAUD.
