Definition
Atresia of the urethra is a rare congenital bladder outlet obstruction, a fetal lower urinary tract obstruction (fetal LUTO), that is usually fatal. Unless there is some other egress for the urine to escape the bladder, such as patent urachus or anuro-rectal communication, these lesions are not compatible with renal development.
