Urinary tract obstruction is a urologic disease consisting of a decrease in the free passage of urine through one or both ureters and/or the urethra. It is a cause of urinary retention.

Causes[edit]

Causes of urinary tract obstruction include:

Congenital urinary tract obstruction[edit]

Urinary tract obstruction as a congenital disorder results in oligohydramnios which in turn can lead to the Potter sequence of atypical physical appearance. Pulmonary hypoplasia is by far the main cause of death in the early neonatal period for children with congenital lower urinary tract obstruction.[1]

Fetal surgery of congenital lower urinary tract obstruction seems to improve survival, according to a randomized yet small study.[1]
