Nephroptosis and hypertension.

The degree of renal mobility was measured in patients with and without hypertension to evaluate a suggested causal relation between nephroptosis and hypertension. In contrast to men, women often showed pronounced renal mobility and the degree of renal mobility correlated positively with the blood-pressure. Fibromuscular dysplasia of the renal artery was always accompanied by a considerable degree of renal mobility on the side involved. The results of this study indicate that in women there may be an association between abnormal renal mobility and the development of high blood-pressure.
