What are the Histological Changes Observed in UTIs?
Histological changes in UTIs can vary depending on the severity and duration of the infection:
1. Acute UTI: In acute infections, there is usually an influx of neutrophils into the affected tissues. The bladder epithelium may exhibit hyperemia (increased blood flow), edema, and even ulceration in severe cases.
2. Chronic UTI: Chronic infections often lead to more complex histological changes such as fibrosis, lymphocytic infiltration, and changes in the urothelium. You might also observe the formation of lymphoid follicles.
