加齢による腎の形態の変化に関する臨床的研究 - 99mTc-DMSA腎シンチグラフィーによる加齢に伴う腎の形態の変化について -

Abstract

We studied the change of renal shape due to development and aging by using 99mTc-DMSA renal scintigraphy. In pediatric age group, the angle between renal longitudinal axis and the lumbar vertebrae is small but becomes larger with aging. The renal size grows with aging in the adult age group, and becomes largest. In geriatric age group it decreases with aging. The stability of renal position is marked in the adult age group, but in the pediatric and geriatric age group it seemed unstable. Renal contour is smooth in the pediatric and adult age group but unsmooth in the geriatric. 99mTc-DMSA renal image shows diffusely homogeneous renal uptake in the pediatric and adult age groups but not homogeneous in the geriatric.
