What a journey — losing a kidney with no clear explanation, navigating kidney stones, and now getting some confusing information from a new doctor. That's a lot to process, and it's completely understandable to want some clarity here.

To address the question directly: eGFR remains the standard measurement used to stage kidney disease. It hasn't been replaced. Creatinine is actually an important *part* of how eGFR is calculated — along with age and sex — but it isn't used alone to stage kidney disease. Here's a quick breakdown of how eGFR staging still works:

- Stage 1: eGFR 90 or above (normal, but albumin present in urine)
- Stage 2: eGFR 60–89 (mild damage, kidneys still function well)
- Stage 3a: eGFR 45–59 (mild to moderate damage)
- Stage 3b: eGFR 30–44 (moderate damage)
- Stage 4: eGFR 15–29 (severe damage)
- Stage 5: eGFR below 15 (kidney failure)

With an eGFR of 58, that would place someone in Stage 3a territory — something worth discussing closely with a nephrologist (kidney specialist), who would be the most reliable source for kidney disease staging guidance.

It may be worth getting a second opinion from a nephrologist, as they specialize specifically in kidney disease and would be most up to date on current diagnostic standards.
