Tracheoesophageal atresia is associated with increased amniotic (polyhydramnios) fluid due to the inability of the fetus to swallow the amniotic fluid (FA2020 p641 and 359).
Cleft lip is not associated with swallowing abnormality and therefore not associated with polyhydramnios.
Encephalocele is a neural tube defect where the brain protrudes through the skull and into a sac-like covering. It is not associated with polyhydramnios (anencephaly which is a completely open skull with no forebrain is associated with polyhydramnios due to lack of swallowing center in the brain)
Renal agenesis would be associated with OLIGOhydramnios (too little amniotic fluid) because the baby cannot produce urine. This leads to Potter's sequence (FA2020 p578)
Urethral obstruction would also lead to oligohydramnios due to decreased urine production.
