Bladder outlet obstruction in a fetus can impact many aspects of development. Naturally, an obstruction will impact the development of the urinary tract, including the bladder and kidneys. Due to fluid buildup in the bladder, lung development can also be affected by an obstruction, which in turn puts strain on the heart.
When a baby is not releasing urine, it can also result in lower levels of amniotic fluid surrounding the baby. This reduces the "cushion" a baby has, which can delay lung development and limit movement. Other complications from congenital conditions may also be discovered, which is why the fetal care team uses a multidisciplinary approach to care for babies with bladder outlet obstruction.
