What Histological Stains are Used to Identify UTIs?

Various histological stains can be used to identify and assess the degree of infection in UTIs:

- Hematoxylin and Eosin (H&E) Stain: This is the most commonly used stain and helps in identifying the general architecture and cellular details.
- Gram Stain: This is particularly useful for identifying bacterial organisms.
- PAS (Periodic Acid-Schiff) Stain: This stain highlights polysaccharides, useful for identifying fungal infections and the basement membrane of epithelial cells.
- Immunohistochemical Stains: These can be used to identify specific pathogens or inflammatory markers.
