The renal arterial resistance index and renal allograft survival

Article Abstract:

Kidney transplant recipients who have a renal arterial resistance index of 80 or more several months after the operation may have a poor prognosis, according to a study of 601 patients. The renal arterial resistance index is a measure of how well blood is flowing through the artery that supplies blood to the kidneys. A high number means there is not enough blood flowing through the artery. Eighty-eight percent of the patients with a high index experienced a decline in kidney function, started dialysis, or died compared to only 17% of those with a low index.

Angiotensin II type 1-receptor activating antibodies in renal-allograft rejection

Article Abstract:

Antibodies against HLA antigens cause refractory allograft rejection with vasculopathy in some patients. A non-HLA, anogiotensin II type 1 [AT(sub 1)] -receptor-mediated pathway might contribute to refractory vascular rejection, and affected patients might benefit from removal of [AT(sub 1)] -receptor antibodies or from pharmocologic blockade of [AT(sub 1)] receptors.

Use of Doppler ultrasonography to predict the outcome of therapy for renal-artery stenosis

Article Abstract:

Patients with renal artery stenosis whose resistance-index is 80 or more may have a poor outcome following surgery. Resistance-index is a measure of blood flow through the renal arteries using Doppler ultrasound.
