Urinary particulate activity in urinary calculus disease.

D N Adamthwaite

    British Journal of Urology
    |February 1, 1983
    PubMed
    Summary

    A new method using a Coulter Counter detects abnormal particulate activity in urine, identifying previously undiagnosed cases of urinary calculus disease. This finding is crucial for understanding kidney stone formation in patients without biochemical markers.

    Area of Science:

    • Nephrology
    • Biochemistry
    • Medical Diagnostics

    Background:

    • Urinary calculus disease (kidney stones) affects many patients.
    • A subset of patients with kidney stones lacks identifiable biochemical abnormalities.
    • Existing diagnostic methods fail to detect underlying causes in these cases.

    Purpose of the Study:

    • To introduce a novel method for detecting particulate activity in urine.
    • To identify urinary abnormalities in patients with kidney stones who show no biochemical markers.
    • To differentiate between normal individuals and those with urinary calculus disease.

    Main Methods:

    • A Coulter Counter was employed to measure particulate activity in freshly voided urine samples.
    • Urine from 100 healthy controls was analyzed.
    • Urine from 100 patients diagnosed with urinary calculus disease was analyzed.

    Main Results:

    • The study demonstrated a statistically significant difference in particulate activity between normal controls and patients with urinary calculus disease (P < 0.001).
    • The Coulter Counter method successfully identified abnormalities in patients previously lacking biochemical markers.
    • This method provides a new diagnostic approach for specific kidney stone cases.

    Conclusions:

    • Particulate activity measurement in urine is a viable method for diagnosing urinary calculus disease.
    • This technique can identify abnormalities in patients with no demonstrable biochemical abnormalities.
    • The findings suggest a new pathway for understanding and potentially treating kidney stone formation.
