Age-related changes in the human renal veins and their valves.
Age-related anatomical changes in the human renal veins and their valves were studied. The principal changes were: 1. The muscle fiber bundles were noted to progressively atrophy as a function of age, while conservely the elastic fiber bundles hypertrophied. 2. The valves of the renal veins were observed to become gradually thicker with age as a result of the increased number of collagen fiber bundles.
