Bladder outlet obstruction (BOO) is a blockage of the bladder. It is sometimes also referred to as fetal lower urinary tract obstruction (LUTO). This blockage prevents the urine flow into the amniotic fluid. Because of this, the amniotic fluid level can become very low. Low amniotic fluid levels (oligohydramnios) impair the developing lungs causing them to become very small (hypoplastic). Babies with little or no amniotic fluid early in gestation (before 24 weeks) may have severely underdeveloped lungs. As a result, these babies have a poor chance of survival. Babies that have a moderate amount of fluid do better as their lungs are able to mature.

The University of Michigan offers fetal intervention for the following conditions
A congenital diaphragmatic hernia (CDH) means there is a hole in the diaphragm. The hole permits the abdominal organs to move into the chest area before birth. Because of this shift into the chest, the lung on the side of the hole is prevented from growing normally. The lung on the opposite side is also smaller than expected. Small lungs can also be called pulmonary hypoplasia.
Approximately 150,000 babies are born in the U.S. each year with a birth defect. The University of Michigan Fetal Diagnosis and Treatment Center offers our patients access to state-of-the-art diagnostic testing through our Fetal Diagnostic Center.
The Fetal Diagnosis and Treatment Center, part of Michigan Medicine, offers comprehensive fetal services, utilizing the latest technological advances in diagnostics, minimally invasive surgeries and open surgeries to best care for a pregnant mother carrying a fetus with a birth defect
Gastroschisis refers to an opening, or ‘hole’, in the abdominal wall. This defect, or ‘hole’, occurs very early in gestation—around the 6th week of development.The defect allows the baby’s bowel, and sometimes other organs, to move outside the body for the remainder of the pregnancy.
At Michigan Medicine, our Maternal-Fetal Medicine Division works together with a team of specialists to manage high-risk pregnancies, optimize fetal well being, educate and support families and provide hope to the tiniest of patients.
Omphalocele refers to an opening, or hole, in the abdominal wall. During prenatal development, the bowel and liver protrude through the hole and remain outside of the abdomen. These organs are covered by a thin layer of tissue known as a sac. The umbilical cord inserts into the sac. The size of the howl can range from small to very large. Omphalocele occurs in about 1 in every 5,000 births, and more often in mothers over the age of 35 years.
Myelomeningocele is a defect of the spine, and of the passage inside the spine called the spinal canal. It can occur at any point along the spine. During early fetal development, the spine comes together like a zipper covering the spinal cord and nerves. Incomplete closure of the spine is referred to as spina bifida, or a neural tube defect.
A sacrococcygeal teratoma (SCT) is a tumor located at the base of the spine, often called the ‘tail bone’ in the area just above the buttocks. This kind of tumor is made up of different cells found during very early development. The tumor usually has both solid and cystic (fluid-filled) parts. Tumors with a greater cystic (fluid-filled) component may grow more slowly than those with more solid tissue. Some of the more solid tumors have a very large blood supply that can cause complications during the pregnancy and in the post-operative period. Large tumors can extend into the pelvis and affect other organs.
The University of Michigan Fetal Diagnosis & Treatment Center offers the full range of fetal procedures from an expert team to diagnose and treat conditions before a child is born.
Twin reversed arterial perfusion (TRAP) used to be known as acardiac twin pregnancy. It is a very rare type of twinning that is only seen in pregnancies with only one placenta, happening in about 1 in every 35,000 identical twin births.
Twin-to-twin transfusion syndrome (TTTS) is a rare complication of pregnancy that develops in 10-15% of twins when the babies share the same placenta (monochorionic). TTTS can occur with triplet or quadruplet gestations if babies share the same placenta. All babies who share a placenta share blood between them through connecting blood vessels. If the blood is shared equally, the babies will do fine. If there is unequal sharing of blood flow that can cause TTTS. It may develop any time in the second or third trimester of pregnancy.
