That's your complete study guide, built straight from authoritative nephrology and pathology textbooks. Here's a quick summary of what's in there:

Acid-Base - The 4 disorders (metabolic/respiratory acidosis and alkalosis), how to classify them using pH + HCO3- + PCO2, the anion gap formula with the MUDPILES mnemonic, and compensation formulas.
Nephrotic vs. Nephritic - The coffee filter analogy to lock in the concept, complete feature tables, and causes of each. The single biggest exam trap: RBC casts = nephritic, absent = nephrotic.
Urine Casts - A complete cast guide with what's inside each cast and what disease it points to, plus an actual microscopy image.
Acute Kidney Injury - The prerenal/intrinsic/postrenal classification with urine findings for each, including the ATN muddy brown cast vs. AIN WBC cast distinction.
Acute Cystitis - Symptoms, organisms, first-line treatment (nitrofurantoin, TMP-SMX, fosfomycin), and how to distinguish cystitis from pyelonephritis.

The master table at the end is your quick-reference for pattern recognition under exam pressure. You've got this.
