Acute Hypertension Following Trauma to Hydronephrotic Kidney: Case Report

Abstract

Trauma to a hydronephrotic kidney in a 12-year-old boy resulted in an acute, severe arterial hypertension which was immediately relieved by nephrectomy. The usual mechanisms responsible for post-traumatic hypertension, i.e. renal artery stenosis/occlusion, or sub-capsular hematoma, were excluded as causative agents. It is suggested that the hydronephrosis may have been associated with an asymptomatic elevation of renal pres-sor activity, and that the trauma somehow triggered an additional release of renin from the diseased kidney. The clinical importance of early treatment of post-traumatic hypertension, as well as long-term-control after renal trauma, is emphasized.
