[Renal tubular dysgenesis].
Renal tubular dysgenesis (RTD) is a very rare malformation, only 24 cases having been described. We present the case of twins born after 28 weeks gestation to a newly-arrived Ethiopian immigrant in whom oligohydramnios was diagnosed when she was admitted. 1 twin had developed polyhydramnios, died before birth and was born with hydrops fetalis. The other newborn suffered from pulmonary distress and anuria, and died 2 days after birth. At autopsy there were no apparent changes in the kidneys or urinary tract, but histological examination showed absence of proximal convoluted tubules. This was attributed to RTD and confirmed by histochemical examination.
