Area of Science:

  • Nephrology
  • Histopathology
  • Diagnostic Pathology

Background:

  • Percutaneous renal biopsies are crucial for diagnosing kidney diseases.
  • Tissue division for multiple analyses can lead to glomeruli loss in slides.
  • Absence of glomeruli impacts immunohistochemistry and diagnostic accuracy.

Purpose of the Study:

  • To develop a reliable method for verifying glomeruli presence in renal biopsy samples.
  • To reduce costs and time associated with diagnostic slide preparation.
  • To enhance the suitability of slides for immunohistochemical staining.

Main Methods:

  • Utilizing Sudan Red stain on cryostat slides as a control.
  • Comparing Sudan Red staining with traditional Hematoxylin and Eosin (H&E) staining.

  • Evaluating the acceptance of Sudan Red slides by insurance authorities.

    • Main Results:

    • Sudan Red stained slides effectively confirmed the presence and number of glomeruli.
    • This method eliminated the need for additional H&E control slides.
    • The technique proved cost-effective and time-saving for laboratories.

    Conclusions:

    • Sudan Red staining is a viable and efficient method for glomeruli assessment in renal biopsies.
    • The approach improves diagnostic workflow by ensuring slide suitability for further analysis.
    • This method also offers valuable information on steatosis, aiding comprehensive kidney assessment.
