[Morphological changes of the female urinary bladder in the elderly. Chronic infections of the urinary tract; the importance of their intensive treatment as preparatory measure for rehabilitation (author's transl)].

The urinary bladder of the elderly is showing a reduced adaptability on account of morphological changes; it is therefore more prone to infections. The morphological changes consist in a reduction of muscle fibres and in an increase of collagen fibres and in elastosis, furthermore in a sklerosis of the intramural arteries. 58% of our chronically - ill patients prove to have a chronic infection of the urinary tract.
