oligohydramnios

• “Initial ultrasound evaluation at 20 weeks gestation revealed a male fetus with a significantly enlarged bladder, severely decreased amniotic fluid volume (oligohydramnios) and bilateral hydronephrosis.”

  Lower Urinary Tract Obstruction (LUTO)

• “View larger image » If the serial fetal bladder drainages for urinary electrolytes and protein components come back favorable and if there is a recent history of decreased to no amniotic fluid (oligohydramnios, anhydramnios) and no chromosomal abnormalities in a male fetus, the family may be offered fetal intervention with a vesicoamniotic shunt placement or fetal cystoscopy to further evaluate the source of fetal urinary tract obstruction.”

  Lower Urinary Tract Obstruction (LUTO)

• “During the third trimester, the baby is at risk for gastroschisis-related complications such as bowel dilatation (stretching), decreased fetal growth rate, oligohydramnios (low volume of amniotic fluid, indicating reduced fetal kidney function), and, in only very rare cases, death.”

  Gastroschisis

• “Natural history studies in pregnancies with early urinary tract obstruction and oligohydramnios suggest the chances of survival to be less than 5 percent, with expectations for severe renal impairment.”

  Lower Urinary Tract Obstruction (LUTO)

• “Amongst the twins with twin-twin transfusion syndrome, the donor twin had mild oligohydramnios, a small bladder, marginal insertion of the umbilical cord into the placenta and an elevated umbilical artery Doppler velocimetry findings suggesting increased placental resistance to blood flow.”

  Twin-Twin Transfusion Syndrome (TTTS)

• “The patient returned at 19 weeks for reevaluation, which now demonstrated minimal amniotic fluid (severe oligohydramnios) around the donor fetus, as well as a tiny, non-filling bladder and significantly abnormal Doppler findings with absence of end-diastolic flow in the umbilical artery, suggesting increased placental resistance compared to her prior studies of twin-twin transfusion syndrome.”

  Twin-Twin Transfusion Syndrome (TTTS)

• “The donor twin had already begun to reestablish normal amniotic fluid volume within its amniotic sac, and the bladder was of normal size (it had previously had severe oligohydramnios and a tiny, non-filling bladder).”

  Twin-Twin Transfusion Syndrome (TTTS)

• “Adzick NS, Harrison MR, Glick PL, Villa RL, Finkbeiner W: Experimental pulmonary hypoplasia and oligohydramnios: Relative contributions of lung fluid and fetal breathing movements.”

  Obstructive Uropathy, Fetal Intervention for Obstructive Uropathy

• “When fetal urination is impaired, the opposite complication, oligohydramnios, usually occurs.”

  I did not know that: fetuses urinate and (can) poop

• “A condition where there is too little amniotic fluid in the sac is called oligohydramnios.”
