  A weak negative correlation between renal Sr 2+ clearance (CR E ) and plasma concentrations of PTH was observed in normocalciuric patients, indicating the control that PTH exerts similar on tubular Sr 2+ reabsorption as on tubular Ca 2+ transport ( 15 [clinchem.aaccjnls.org]

  Although kidney stones are not a significant cause of kidney failure, epidemiological data suggest that most people who develop kidney stones have mildly compromised kidney function (Gillen 2005). [cochranelibrary.com]
