[Results of the treatment of renal artery stenosis in transplanted kidneys].

Fifty-six renal artery stenoses involving transplanted kidneys among a series of 819 renal transplants performed from 1978 to 1986 were treated. Forty-two patients underwent surgery. Surgery was the initial treatment in 38 cases and followed failed or complicated dilatation in four cases. Surgical treatment ensured successful control of hypertension in 85% of cases with a mean time lag of 26 months. Recurrence rate was 12%. Two patients died in the perioperative period. Percutaneous dilatation was performed in 18 renal artery stenoses and ensured control of hypertension in 61% of cases with a mean time lag of 19.6 months and a 33% recurrence rate.
