<unk>  syndrome is not technically a syndrome as it does not collectively present with the same telltale characteristics and symptoms in each and every case. It is more accurately described as a<unk> " or chain of events that may have different beginnings (absent kidneys, cystic kidneys, obstructed ureters or other causes), but which all end with the same conclusion (absent or reduced volume of amniotic fluid). This is why<unk>  syndrome is often called<unk>  or oligohydramnios<unk>  by some clinicians and researchers. The term<unk>  syndrome is most frequently associated with the condition of oligohydramnios<unk>  regardless of the root cause of the absence or reduced volume of amniotic fluid. However, as noted in this article, the term<unk>  syndrome was initially coined in order to refer to fetuses and infants with BRA. It was not until later that the term became more encompassing as it was noted that other causes of failed fetal urine production also resulted in similar physical characteristics and prognoses of the fetuses and infants with BRA (that which<unk>  originally described in 1946). Since then, the term<unk>  syndrome has become a misnomer and experts have attempted not to eliminate the terminology, but to modify it in a way so as to be able to determine the different root causes by creating a nomenclature system. However, this classification system has not caught on in the clinical and research fields.
