Aims & Objectives: 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). Subjects & Methods: One hundred patients (age 20-60years) 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. Results: When results were summed up and testParameters 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. Conclusions: 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 inorder to evaluate this relation.

Urinary Oxalate Excretion

Twenty-two recurrent calcium stone formers had 24-h urinary oxalate excretions on their home diets which were significantly greater than those of 30 normal subjects (0·48±0·23 mmol/d; mean±SD compared with 0·31±0·11; P<0·01). The stone formers also demonstrated marked day to day variability in oxalate excretion indicating that a single normal urinary oxalate measurement did not exclude significant hyperoxaluria at other times. On a hospital diet containing 1000 mg calcium per day, urinary oxalate excretion fell significantly from 0·48±0·23 mmol/d to 0·32±0·12; P<0·01. As the urinary calcium excretion in and out of hospital was similar, it seems unlikely that low calcium intake at home was responsible for the hyperoxaluria. All patients had recurrent symptomatic stone disease and had been advised to avoid foods rich in oxalate. Whilst poor compliance is a possible explanation for the variability in oxalate excretion, we believe it is more likely that there is an inadvertent intake of oxalogenic precursors in their diet. As normal subjects do not demonstrate hyperoxaluria on similar home diets, stone formers may have a metabolic defect in the handling of these precursors.

Kinetics Of

1. Seventeen healthy controls and 63 patients with idiopathic calcium stone disease of the urinary tract were investigated for urinary calcium and oxalate excretion and for [14C]oxalate intestinal absorption. 2. Under comparable controlled dietary intake a significant increase in calcium excretion was found in patients with stone disease. Oxalate excretion and [14C]oxalate intestinal absorption were mildly but not significantly increased. When patients with stone disease were subdivided into normocalciuric and hypercalciuric subjects, oxalate excretion and [14C]oxalate absorption were significantly increased in the latter. There was a significant direct relationship between calcium excretion and both oxalate excretion and [14C]oxalate absorption. 3. [14C]Oxalate absorption increased significantly in 22 stone-formers when dietary calcium was changed from normal to low. 4. The kinetics of [14C]oxalate intestinal absorption showed that the main difference between normocalciuric and hypercalciuric subjects occurred within the first 6 h after the oxalate-labelled meal. 5. These results confirm that mild hyperoxaluria is a frequent feature of idiopathic calcium stone disease even when patients and controls are studied under controlled dietary conditions. Our data are consistent with the hypothesis that hyperoxaluria is secondary to calcium hyperabsorption and is upper intestinal in origin.
