Index - Part A (Doc One)

Part B - how it fits with Part A

Part A answers the twelve Doc One PYQ essays (nephron segments, loop of Henle, concentrating mechanism, bladder, GFR, potassium, casts, AKI biomarkers, metabolic-hormonal functions). Part B adds the six unique short-note topics from Doc Two not covered in Part A - duplicated topics are omitted and cross-referenced. Same Cornell layout, Pareto highlighting and colour-coded boxes throughout.

How to use this chapter

CORE One M What is TIN?

Define before you list tests - examiners give a mark for this line.

Tubulointerstitial nephritis (TIN) equals inflammation of the tubules and interstitium with relative sparing of glomeruli and vessels. The physiological signature is tubular dysfunction out of proportion to the fall in GFR - so renal function tests are chosen to expose each segment.
