The impact of calculi weight and frequency of calculi formation on their compositions

الملخص EN

The present investigation was conducted to evaluate the effect of calculi weight and the frequency of calculi formation in their compositions.

The present investigation was conducted to evaluate the urinary calculi compositions quantitatively.

Fifty-two calculi were obtained from 38 males and 14 females afflicted with urolithaisis, the calculi were subjected to qualitative analysis, and sought for calcium, uric acid, phosphorus, oxalate, magnesium and ammonium ion contents.

Small calculi were demonstrated to be rich in calcium oxalate, while large calculi were rich in calcium phosphate.

The frequency of calculi formation was demonstrated to influence the calculi compositions.

Thus, calculi of non-stone formers were exhibited to be rich in calcium oxalate, while those of stone formers were rich in uric acid.
