Transplant renal artery stenosis

Renal artery stenosis occurred in 13.5% of 229 consecutive cadaver renal transplants performed at the Royal Melbourne Hospital over an eight and a half year period. Clinical and laboratory indices which suggested the diagnosis were examined. The presence and severity of hypertension were of little predictive value, while deterioration of renal function for which other causes had been excluded and the histological appearance of renal biopsy speciments were valuable in suggesting the diagnosis. A selective approach in both investigation and attempted surgical repair is recommended.
