Case Reports
[Study of the renin-angiotensin system in 2 cases of Wilm's tumor with severe arterial hypertension].
Two children who presented with Wilm's tumour and severe hypertension are described. The hypertension, which was secondary to excessive renin secretion, regressed after unilateral nephrectomy. In one child the total quantity of renin in the tumour was high and the peripheral plasma renin was also increased. ⋯ No renin was detected in the tumour. In this child the inappropriate secretion of renin was probably due to renal parenchyma close to the tumour causing reno-vascular hypertension. The anti-hypertensive effect of propranolol given pre-operatively was excellent.
