Three patients with severe hypertension and rapidly progressive oliguric renal failure who required dialysis were found by aortography to have bilateral renal artery occlusion or stenosis. Each had peripheral arteriosclerosis or an abdominal bruit. Following renal artery reconstructive surgery, all three patients recovered nearly normal renal function in 3 to 12 weeks, though mild hypertension persisted in two patients. The common findings of a normal-sized kidney with collateral blood flow and nearly normal histological features were predictive of recovery of renal function. Prolonged postoperative oliguria in two patients may have been due to increased preglomerular vascular resistance mediated by the renin-angiotensin system.

Successful renal transplantation in Wegener's granulomatosis.

Two patients with Wegener's granulomatosis, who were in complete remission secondary to cyclophosphamide therapy but who had end-stage renal failure, were treated with renal transplantation. Neither patient has clinical evidence of recurrent glomerulonephritis 10 and 28 months after receiving the renal transplants. Cytotoxic therapy has been proved to be highly effective in inducing and maintaining remission in patients with Wegener's granulomatosis; thus increasingly larger numbers of patients will be seen who, despite being maintained in complete remission, will have markedly impaired renal function due to previous acute damage. Renal transplantation can now be considered an acceptable alternative form of therapy in such patients.
