[Combination of renal artery stenosis and pyelonephritis in arterial hypertension]

Stenosis and thrombosis of the main renal artery were detected in 248 of 867 patients with arterial hypertension (28%). The combination of renal artery stenosis with pyelonephritis was encountered in 19% (46 subjects) of patients with the affected main renal artery. The syndrome of malignant arterial hypertension in the combined affections was diagnosed in 39.1% of patients. The study of the total renal filtration function in combined diseases may be of prognostic importance from the standpoint of normalization of arterial pressure after surgical treatment.
