The urinary tract: The urinary tract consists of the organs that produce and store urine: Two kidneys Two ureters The urinary bladder The urethra Lower urinary tract obstructions (LUTO), also known as obstructive uropathy, are rare birth defects that occur in 1 in 5,000 to 7,000 births, commonly in male fetuses. The underlying cause is a partial or complete obstruction of the urethra, the tube that connects the bladder to the amniotic fluid space around the fetus.

babies with LUTO die, even if fetal therapy was performed. How sick a baby will be after birth depends on how severe the lung and kidney damage are, and depends on the cause of the baby's LUTO. For these reasons, it is important to have a thorough evaluation of a baby with LUTO in the NICU, and close monitoring by the baby's pediatrician. Fetal lower urinary tract obstruction (LUTO) is a serious condition, which commonly results in marked perinatal morbidity and mortality. The characteristic prenatal presentation of LUTO includes an enlarged bladder with bilateral obstructive uropathy. While mild forms of the disease result in minimal clinical sequelae, the more severe forms commonly lead to oligohydramnios, dysplastic changes. Lower Urinary Tract Obstruction. View in PDF Format. Fetal lower urinary tract obstruction (LUTO) is a rare condition that is caused by a blockage of fetal urination. Because the baby cannot empty the bladder, the baby's bladder subsequently becomes very large and inflated. Also, because the amniotic fluid is essentially composed of the baby.

Lower urinary tract obstruction (LUTO) refers to a blockage in the urinary tract that restricts or prevents the release of urine from the bladder. Accumulation of urine within the kidneys and bladder throughout pregnancy results in permanent damage to these organs. If urine cannot exit the body, the amount of surrounding amniotic fluid. A final diagnosis was achieved in 143 cases, including 124 of LUTO and 19 reclassified after birth as non‐obstructive megacystis. The optimal bladder volume cut‐off for prediction of LUTO was 35 cm 3 (area under the curve (AUC) = 0.7, P = 0.03). The clinical score formulated on the basis of the multivariate analysis included fetal sex.
Lower urinary tract outlet obstruction (LUTO) is when pee (urine) is partly or completely blocked from leaving the body at the lower urinary tract. The lower urinary tract includes the bladder and the urethra. This blockage can make the organs swell and cause long-term damage. LUTO also leads to low amniotic fluid during pregnancy. Lower urinary tract obstruction (LUTO) is a complex fetal genitourinary disorder associated with significant morbidity and mortality, which requires diagnostic and management advancement to improve fetal outcomes.
