Hyponatremic-hypertensive syndrome associated with renovascular hypertension: a case report.

Renovascular hypertension occasionally manifests clinically as electrolyte disorders and albuminuria in addition to elevated blood pressure. A 49-year-old man who had renovascular hypertension also had severe hypokalemia, hyponatremia, polyuria and polydipsia that were treated by an angiotensin-converting enzyme inhibitor and resection of an atrophic kidney with a compromised blood supply. This is a case of hyponatremic-hypertensive syndrome related to renovascular hypertension and occurring as an additional abnormality.
