Chronic Renal Failure

Chronic renal failure encompasses a range of conditions leading to progressive kidney dysfunction, often culminating in end-stage renal disease. The majority of cases are attributed to hypertension and diabetes.

Chronic Renal Failure

Chronic allograft nephropathy

Months or yrs after transplant

Runs a progressive course

Stop Analgesics before issues become severe
Papillary Necrosis, then TIN
