Urinary Exertion Of Calcium By Urinary Stone Disease Patients And Normal

J. C. Orakwe


To compare the urinary excretion of calcium by subjects in a known area of high incidence of urinary stone disease, and a known area of low incidence, 12 adult male patients with idiopathic calcigerous urinary stone disease in south-East Nigeria and 55 similar patients from Scotland, United Kingdom were analyzed thirty-six healthy subjects in Nigeria and 30 in Scotland were also analyses as controls. Twenty-four hour urinary excretion of calcium was higher in patients from Scotland (6.81 +0.48mmols/24 hours). It was also higher in control from Scotland (5.96+0.61 mmol/24 hours), than in controls from Nigeria (2.33+0.21mmols/24 hours), and the difference was statistically significant (P< 0.001), Calcium excretion was higher in patients than in controls in both centers.
