Calcium; serum and urinary in stone formers and non-stone formers

ABSTRACT

To evaluate the effects of serum calcium and urinary calcium excretion on upper urinary tract stone diseases in the Peshawar [a high stone incidence belt]. One hundred patients [age 20-60 years] who were suffering severely from upper urinary tract stone disease were selected from LRH and Hayatabad Medical Complex Hospitals of Peshawar, same numbers of healthy controls from the same region were also selected for the study. When results were summed up and test Parameters were compared, it was seen that mean serum calcium in stone formers was greater than that of non-stone formers [P<0.001]. Same pattern was also observed [P< 0.001] in both groups regarding mean urinary calcium excretion. We concluded that calcium is a definitive risk factor in upper urinary tract stone disease. However we suggest further work and research on wide scale population in order to evaluate this relation
