title: Urinary particulate activity in urinary calculus disease.
abstract: In urinary calculus disease there remains a group of patients with no demonstrable biochemical abnormality. A method is described measuring particulate activity in freshly voided urine using a Coulter Counter, which demonstrates the abnormality in these cases. Urine from 100 normal controls and 100 persons with urinary calculus disease was analysed, demonstrating a statistically significant difference between the 2 groups (P less than 0.001).
