腎動脈瘤の8例,とくにレ線診断と血漿レニン活性測定の意義について

Abstract

Renal aneurysm is thought to be a rare disease, but we encountered 8 cases of it for last seven years. They correspond to 0.21 % of patients admitted to our clinical unit for the term. Chief complaints of them were hypertension in three cases (37.5%), flank pain in two cases, hematuria, albuminuria and lumbago in each one case. The diagnosis as well as types and location of aneurysm was made by radiographic examination such as KUB, DIP, abdominal aortography and pharmacoangiography. Particularly, abdominal aortography was indispensable and pharmacoangiography was useful in establishing the location. Additionally, angiotensin II blockade test was valuable in the correlation between renal aneurysm and hypertension due to plasma renin activity. In the treatment of renal aneurysm, aneurysmectomy in four cases and nephrectomy in two cases were performed. All patients did well after operation.
