    Area of Science:

    • Nephrology
    • Stereology
    • Quantitative Pathology

    Background:

    • Accurate counting of renal corpuscles is crucial for diagnosing kidney diseases.
    • Existing stereologic methods present challenges in accuracy and efficiency.

    Purpose of the Study:

    • To evaluate two stereologic methods for counting renal corpuscles.
    • To identify the most accurate and efficient method for kidney studies.

    Main Methods:

    • Comparison of Weibel's stereologic method with the Elias and Hennig method.
    • Evaluation of independence from tissue section thickness and sensitivity to corpuscular size variation.
    • Development and application of a modified Weibel's method to streamline volumetric fraction determination.

    Main Results:

    • Weibel's method demonstrated accuracy and efficiency in counting renal corpuscles in normal and diseased kidneys.
    • Weibel's method is preferred due to its independence from section thickness and sensitivity to corpuscular size.
    • The modified Weibel's method successfully eliminated the need for additional point-counting procedures.

    Conclusions:

    • Weibel's stereologic method is a reliable tool for quantifying renal corpuscles.
    • The modified Weibel's method offers a more efficient approach to determining corpuscular volumetric fractions in kidneys.
