Moreover, a retrospective case-control study based on data from the Rochester Epidemiology Project found stone formers to have a 51%to68%68 % increased risk for a sustained elevation in serum creatinine (SCr) and for a clinical diagnosis of CKD compared with non-stone formers [ 3].
As such we would attain 85% power with a minimum of 80 ureteral stones and a minimum of 256 non-stones.
