Unilateral chronic pyelonephritis and hypertension: coincidental or causal relationship?
Three patients with well documented unilateral chronic pyelonephritis (UCP) of bacterial origin, one hypertensive and two normo-tensive, were presented. Removal of the contracted kidney in the hypertensive patient did not eradicate the hypertension. An attempt was made to define UCP as closely as possible. The clinical, roentgenologic, bacteriologic, functional and pathologic criteria of UCP was described. But, as other conditions may mimic the roentgenologic, functional and pathologic picture of UCP, a history of recurrent urinary tract infection accompanied by a documented unilateral renal bacteriuria is the basic requirement for a sustained diagnosis of UCP. In view of these more exacting criteria in the diagnosis of UCP, and its water and salt-losing functional pattern, UCP is a rare cause of hypertension, in the majority of cases the association of UCP with hypertension is merely coincidental.
