The aim of this study is to determine the relationship between hypertension and the presence of multiple renal arteries in young male patients. Renal arteriographic data of seventy-two young hypertensive men (age: 26.1 ± 6.2 yrs, blood pressure [mmHg]: 162 ± 17.5/104.6 ± 10.1) were examined retrospectively. Angiography was performed in order to exclude the diagnosis of renal artery stenosis. The renal arteriographic data were as follows: no renal arterial abnormalities in 39 patients (54.2%), multiple renal arteries in 24 patients (33.3%), renal artery stenosis in 3 patients (4.2%), unilateral hypoplastic kidneys in 3 (4.2%), horse-shoe kidneys in 2 (2.8%) and arterio-venous malformation in 1 (1.3 %). In patients with multiple renal arteries there were positive correlations between body mass indices and blood pressures (r = 0.58, p < 0.05 for systolic, and r = 0.63, p < 0.001 for diastolic). Despite the high prevalence of multiple renal arteries in young hypertensive men, it’s difficult to declare this abnormality had an obvious role in the pathogenesis of hypertension.
