title: Persistent arterial hypotension after bilateral nephrectomy in a 4-month-old infant.
abstract: A patient with congenital nephrotic syndrome underwent bilateral nephrectomy at the age of 4 months. She showed persistent hypotension from the fourth postoperative day until death at the age of nearly 5 months. No cause for the hypotension could be found. It is postulated that, especially in young infants, a deficiency of renin after bilateral nephrectomy may cause persistent hypotension. An explanation for the putative increased risk of this complication in young infants may be their need for a highly active renin-angiotensin system. Until more is known about the incidence of this complication and its predisposing factors, reluctancy towards the performance of bilateral nephrectomy in children under the age of 6 months is warranted.
