Here’s a mnemonic I just thought up for remembering the clinical features of Chronic Renal Failure while I was studying Pathoma.

Chronic Renal Failure has the following Clinical Features.
“LOW C-OST URETHANE”

LOW Calcium
OSTeodystrophy (Osteoporosis, Osteomalacia, Osteitis Fibrosis Cystica)

Uremia –> U-NAPPED (see below)
RETention of NaCl & Water
HypErKalemia & HypErPhosphatemia (w/ Metabolic Acidosis)
ANEmia

Now, to remember the clinical features of Uremia itself (the “U” above) use the following acronym.
U NAPPED (“You napped”)

Uremia:

Nausea
Anorexia
Pericarditis
Platelet Aggregation & Adhesion Dysfunction
Encephalopathy with Asterixis
Deposits of Urea Crystals in the Skin
