[X-ray guided endovascular repair of venous bed of contracted kidney from pyelonephritis in the treatment of renal hypertension and chronic renal failure]. / Rentgenoéndovaskuliarnaia rekonstruktsiia venoznogo rusla pielonefriticheski smorshchennoi pochki pri lechenii nefrogenni gipertonii i khronicheskoi pochechnoi nedostatochnosti.

For compensation for chronic ischemia of the pyelonephritically contracted kidney, the authors used X-ray endovascular venous revascularization for the first time. The surgical intervention was to stenose the subsegmental veins of the diseased kidney, resulting in recanalization of the arterial system. The outcomes of X-ray treatment were analyzed in 38 patients with chronic degree I-II renal failure and nephrogenic hypertension. In 35 (92.1%) patients of them, there was improvement in the clinical picture of the underlying disease and in the filtrating and reabsorbing function of the kidney operated on, an increase in its sizes, and a decrease in systemic blood pressure.

[Clinical application of X-ray endovascular revascularization of pyelonephritic kidney: first experience]. / Pervyí opyt klinicheskogo primeneniia rentgenoéndovaskuliarnoí revaskuliarizatsii pielonefriticheskoí pochki.

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.
