Renal tubular dysgenesis

Renal tubular dysgenesis is a severe disorder of autosomal recessive inheritance. Anuria already presents in uteri (oligohydramnios) and the children die soon after birth of pulmonary dysfunction.

Clinical Findings

The pregnancy is characterized by oligohydramnios due to fetal anuria. Perinatal death occurs out of pulnonary hypoplasia.

Symptoms also include redundant skin, facial dysmorphia and lung hypoplasia. Often skull ossification defects are present.

Diagnosis

The diagnosis can be made by histomorphology. The kidneys show no or only few differentiated proximal tubules.

Symptoms

Oligohydramnios
Oligohydramnios is the first symptom of RTD. Often the fetal ultrasound also reveals the malformations of both kidneys.
Malformations of the urinary tract
Renal malformations include absence of proximal tubules and renal artery hyperplasia. Early signs can be found by fetal ultrasound along with oligohydramnios.
