**3.9 Urinary calcium excretion in study group**

The mean 24 hours urinary calcium in the CRF group was 68.4+ 12.8mg/dl, and 162 + 40.4mg/dl in the control group. This difference in means is statistically significant (p<0.05). There was an insignificant correlation between 24hours urinary calcium and creatinine clearance, and serum calcium (r =-0.16) and (r =0.02) respectively. There was a statistically significant correlation between 24hours urinary calcium and total serum alkaline phosphatase (r= 0.38) but no significant correlation with sex (r =0.79), age (r=0.46) or bone paint (r =0.23).
