    Area of Science:

    • Nephrology
    • Pathology
    • Biomedical Engineering

    Background:

    • Renal biopsies are crucial for diagnosing kidney diseases.
    • Conventional tissue fixation methods can be time-consuming.
    • Rapid diagnostic techniques are needed for timely patient management.

    Purpose of the Study:

    • To evaluate the efficacy of microwave fixation for renal biopsy processing.
    • To compare microwave fixation with conventional methods for light, immunofluorescence, and electron microscopy.

    Main Methods:

    • Renal biopsy tissues from 10 patients were divided.
    • One portion underwent microwave fixation; the other used conventional methods.
    • Tissues were analyzed using light microscopy, immunofluorescence, and electron microscopy.

    Main Results:

    • Microwave fixation preserved renal architecture and cell morphology effectively.
    • Pathological changes were consistent with formalin-fixed tissues.
    • Immunofluorescence and ultrastructural details were well-maintained, comparable to conventional methods.

    Conclusions:

    • Microwave fixation is a viable and rapid method for renal biopsy processing.
    • This technique ensures diagnostic accuracy across multiple microscopic modalities.
    • The speed of microwave fixation is advantageous for urgent diagnostic scenarios.
