title: [Morphology of the kidneys in arterial hypertension of adrenal genesis (according to biopsy findings)].
abstract: 67 renal biopsies obtained in the course of adrenalectomy from patients with primary hyperaldosteronism, hypercorticism and pheochromocytoma were studied. Sclerotic affection of the arterioles and renal interstitium were found in long lasting adrenal arterial hypertension. This may cause residual postoperative hypertension. Endocrine nephropathy in primary hyperaldosteronism due to hypopotassemia and alcalosis manifests with vacuolar distrophy and atrophy of the epithelium, dilatation of tubular lumen, intratubular calcinosis and tubulointerstitial nephritis. Primary hyperaldosteronism was characterized by hypoplasia of the juxtaglomerular apparatus (JGA) but in massive spironolacton therapy signs of enhanced renin-secreting function of the glomerular efferent arteriola may be observed. In hypercorticism pyelonephritis is rather frequent. In patients with pheochromocytoma hypercatecholaminemia may result in JGA activation this being particularly evident in renal artery stenosis. Recurrent hypertension after pheochromocytoma removal in the absence of renal pathology may indicate recurrent tumor or missed second tumor.
