[Clinical application of X-ray endovascular revascularization of pyelonephritic kidney: first experience].

For compensation of schronic ischemia of the pyelonephritically afflicted kidney, the authors first used peripheral venous revascularization. The surgical intervention involved X-ray endovascular stenosing of the subsegmental renal veins. Local rearrangement of venous circulation provided a better ischemic tolerance due to more complete oxygen uptake from the highly oxygenized renal venous blood. The results of peripheral venous revascularization were analyzed. There were improvements in the clinical presentation of the underlying disease, in the filtration and reabsorption of the kidney exposed to operation, and a reduction in blood pressure.
