What are the Histological Techniques Used for Examining Bladder Tissues?
Once the biopsy samples are obtained, several histological techniques are employed to study the tissues:
- Fixation: The tissue is preserved using chemical fixatives. - Embedding: The tissue is embedded in a solid medium, usually paraffin wax. - Sectioning: Thin slices of the tissue are cut using a microtome. - Staining: The tissue sections are stained to highlight different cellular components. Common stains include Hematoxylin and Eosin (H&E), Periodic acid-Schiff (PAS), and Immunohistochemical stains. - Microscopic Examination: The stained tissue sections are examined under a microscope to identify any pathological changes.
