Influence of different factors on the formation of calcium oxalate stones. II. Discriminant analytical computations of morphological parameters of pelvic-calyceal systems and clinicochemical urine parameters of controls and calcium-oxalate stone formers.

Until now almost exclusively clinicochemical urine parameters have been used to determine the risk of urinary stone formation. In part I of this study pelvic-calyceal systems of healthy persons and calcium oxalate stone formers are compared with regard to their morphology, whereas urine parameters will be briefly included in part II. Discriminant functions are given by means of which it is possible to calculate the risk and, e.g. to quantify a follow-up.
