[X-ray guided endovascular repair of venous bed of contracted kidney from pyelonephritis in the treatment of renal hypertension and chronic renal failure].

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.

[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.
