text: Sixty-two cases, oligohydramnios in the mix,
  Diagnosed by ultrasound, 13 to 28 weeks' gestation, kicks,
  Ultrasonographers, three pros with the vision,
  Subjective scale rating, mild, moderate, severe, anhydramniotic condition.
  
  Reliability on point, intraclass correlation coefficient 0.81,
  Perinatal mortality rate, 43% ain't great,
  Pulmonary hypoplasia, 33% caught in the mix,
  Lethal congenital anomalies, one-third, that's the fix.
  
  Adverse outcomes linked to severe degrees,
  Oligohydramnios, lethal results indeed,
  88% of the fetuses in that severe flow,
  Anhydramnios too, lethal outcomes show.
  
  Mild and moderate group, just 11% in the zone,
  Adverse outcomes less, but still not fully blown,
  Anuric urinary tract anomaly, the most severe it seems,
  Uniformly fatal, no escaping those dreams.
  
  Pulmonary hypoplasia, severe group, 60% in the scene,
  Moderate group, only 6%, not that mean,
  Experienced observers, subjective grading rules,
  Reliable and predictive, outcome's tools.
  
  Severe oligohydramnios, second trimester's strife,
  Predictive of poor fetal outcome, that's life,
  Time to search for etiology, dig deep,
  Consider intervention, don't just sleep.
  
  Moderate grades, a glimmer of hope,
  Reduced amniotic fluid, optimism to cope.
