Kidney Stones Affect Gfr. Glomerular filtration is the main life sustaining kidney function and kidney stones can cause enough damage to lower it. In general a good gfr number is above 60 and a good creatinine number is below 1 2.
A rate between 30 and 59 mls min 1 73m 2 puts you into stage three ckd and rate between 15 and 29 mls min 1 73m 2 are considered stage four ckd. Glomerular filtration is the main life sustaining kidney function and kidney stones can cause enough damage to lower it.

Often stones form when the urine becomes concentrated allowing minerals to crystallize and stick together. Passing kidney stones can be quite painful but the stones usually cause no permanent damage if they re recognized in a timely fashion. Given that stone risk varies powerfully with urine calcium excretion a lower gfr that lowers calcium excretion must lower stone risk unless it led to a reduced urine flow rate.
