Abstract
The increased excretions of lithogenic substances (calcium, oxalate and uric acid) are known to be significant risk factors in stone formation1. Twenty five stone formers (SF) and age-sex-matched healthy subjects were asked to collect 3 h urine samples over a 24 h period. These were analyzed for calcium, oxalate, and uric acid by routine procedures. Computer programs using the method of least squares were used to detect a circadian rhythm2.
