Mnemonics to remember differential diagnoses are usually cumbersome, difficult to remember, and unnecessary. However, sometimes one stands above the crowd.
Sometimes, one is so perfect that the world around you seems brighter… the greens greener… the sky bluer… your lunch tastier…
Feel your mental status exam improve as I present to you “IS THIS PP RED?” for hematuria.
The best part about the mnemonic? – The two most important etiologies are first!
- I – Infection (UTI, urethritis, etc)
- S – Stones
- T – Tumour (bladder, renal), Tuberculosis
- H – Hemolytics uremic syndrome, Henoch-Schonlein Purpura
- I – Inflammation (irritation, radiation cystitis, insertion of foreign body)
- S – Streptococcus glomerulonephritis, SLE, sickle cell
- P – Prostatitis (in pediatrics, posterior urethral valves)
- P – Pseudohematuria (menses, beets, rectal bleed, urate crystals in babies)
- R – Renal vein thrombosis
- E – Exercise-induced
- D – Drugs (contrast, cyclophosphamide)
