[Long-term follow-up study of renal autotransplantation in reno-vascular hypertension].

Therapeutic effects of heterotopic renal transplantation for renovascular hypertension were evaluated in ten patients with a follow-up period of more than three years. These ten patients consisted of 4 males and 6 females with the range of age from 21 to 55. The causes of renovascular hypertension were fibromuscular dysplasia in five patients, atherosclerosis in 3 and aortitis syndrome in 2. All the ten patients had a unilateral stenosis of the renal artery. At 3 years after operation, the blood pressure fell to normal range without any medication in 9 patients (90%) and it could be controlled with antihypertensive drugs in the remaining one patient. Operative mortality or deterioration of graft function was not experienced in any of them. One of the female patients had three deliveries after operation. The heterotopic renal autotransplantation is a therapeutic method to be selected for renovascular hypertension, since excellent and stable long-term results can be achieved.
