title: [Arterial hypertension with renin hypersecretion secondary to pyelo-ureteral syndrome. Cure after corrective surgery].
abstract: In a 22 years old woman with recent hypertension, a timed intravenous pyelogram revealed an asymptomatic obstructive ureteropelvic junction. Preoperative renal vein catheterization demonstrated excessive renin release from the diseased kidney and low release from the other one, suggesting that corrective ureteral surgery should return blood pressure to normal levels. Moderately impaired glomerular filtration rate improved after surgery as a consequence of suppressed hydronephrosis and bilateral renal ischemia. Thus we conclude that in young people, asymptomatic unilateral hydronephrosis can lead to hypertension and renal failure like renal artery stenosis. In the other cases of urinary flow obstruction, secondary hypertension remains to be explained by both inappropriate production of renin and water chronic retention.
