Age-Related Changes in the Urinary Bladder of the Female Albino Rats

Disturbances of the urinary bladder functions are common in the elderly people particularly women. So, it was the aim of the present work to detect the age-associated changes in the urinary bladder that might play a role in the bladder dysfunctions. Twenty albino rats were used in the present work....

So, it was the aim of the present work to detect the age-associated changes in the urinary bladder that might play a role in the bladder dysfunctions. Twenty albino rats were used in the present work. They were divided into two equal groups, each consisted of ten rats. The first group included the adult rats (aged 3 months) and served as control group, while the second group was the senile rats (aged 24 months). Specimens of the urinary bladder were taken, processed and examined using the light microscope (LM) and the scanning electron microscope (SEM). Light microscopic examination of the urinary bladder of the aged rats showed marked mucosal damage, ranging from degeneration of the epithelial cells to complete denudation of the mucosa with exposed lamina propria. Cellular infiltration and increased dilated and congested blood vessels of the lamina propria were also encountered. The smooth muscle cells of the muscularis showed variable degrees of degeneration with wide separation of the muscle bundles. Massive increase in collagen fibres deposition was detected in the lamina propria, muscle layer and adventitia.
