GFR <60 for >3months w. or without kidney damage
How many stages are there of chronic kidney disease
0-5
What is normal GFR
120ml/min
What is stage 0
increase risk for CKD, GFR >90 ml/min +risk factors such HTN and Diabetes
What is goal of stage 0
screening and risk reduction
What is Stage 1
Pre-clinical CKD, GFR >90, but evidence of kindey damage
What is goal of Stage 1
reverse or stabilize Cardiovascualr risk reduction
What is Stage 2 CKD

In Stage 4 progression to ESRD is within
2-4 years
What is goal of Stage 4
slow progession, prepare for replacement, treat complications

Should you evaulate pts with diabetes or other higher risk populations YEARLY for CKD, using what
Spot unrinary ablumin
mincoanalysis of urine
After an insult to kidney it leads to loss of nephrons, what happens
adaptation, good nehprons increase in size and fuction
After kidey adpats, solute balance is maintain though
increase GFR of remaining nephrons
Increase in secretion
Decrease in reabsorption
What is the negative consequnce of adaptation
progression of kidney failure, other nehprons begin to wear out, and also die
Progession of CKD is fueled by
adaptation

Increase in Glomerular pressure leads to
capillary and endothelial and dysfuction, basement membrane thicking, and proteinuria
