The accumulation of "cysteine" in "urine" due to a defect in this amino acid's reabsorption.

  • Kustis (Greek) - Bladder, atomical pouch or sac

  • Kidney stones
  • Autosomal recessive
  • Proximal convoluted tubule defect
  • An autosomal recessive disorder that prevents the proper reabsorption of cystine and other basic amino acids in the proximal convoluted tubule resulting in an excess of this AA in the urine. A frequent cause of persistent kidney stones.
  • Diuretic

    A substance that increases the production (think "throughput" or "flow through") of "urine".

    • Dia (Greek) - Through, completely
    • Ouron (Greek) - Urine
  • Examples include: thiazides, carbonic anhydrase inhibitors, potassiumsparing diuretics, and loop diuretics. Diuretics are used to treat heart failure, liver cirrhosis, and hypertension.

    The excretion of "sweet wine" or sugar in the "urine".

    • Glykys (Greek) - Sweet, sweet wine
    • Ouron (Greek) - Urine
  • Usually seen in those with untreated diabetes or renal damage
  • Hematuria

    "Blood" in the "urine".

  • The most common causes of hematuria are urinary tract infections (UTIs), kidney stones, or bladder stones. In older men, consider benign prostatic hyperplasia in the differential.
  • Less commonly seen but frequently tested causes of hematuria include IgA nephropathy, trauma, glomerulus disease, sickle cell trait/disease, rhabdomyolysis, renal cell carcinoma and drugs
  • Common drugs that cause hematuria include rifampin, metronidazole, chloroquine, sulfonamides, and phenytoin
  • Hemolytic uremic syndrome

    The triadic set of symptoms "running" "together" of anemia due to "loosening" of red "blood" cells, thrombocytopenia, and acute renal failure (leading to "urine" in the "blood"

    • Haima (Greek) - Blood
    • Lutikos (Greek) - Able to loosen
    • Ouron (Greek) - Urine
    • Haima (Greek) - Blood
    • Syn (Greek) - With, together
    • Droma (Greek) - Running, A Course
  • Associated with EHEC serotype O157:H7 and Shigella
  • Argentina has the highest incidence of HUS.
  • Homocystinuria

    Disease that results in the presence of amino acids that are almost the "same" as cystine in the "urine". The amino acid cysteine was so med for having been found in the "bladder"

    • Homos (Greek) - Once and the same, like
    • Kustis (Greek) - Bladder, atomical pouch or sac
    • Ouron (Greek) - Urine
  • Disorder of metabolism of methionine
  • Characterized by elevated urine homocysteine, mental retardation, osteoporosis, lens subluxation, and atherosclerosis
  • May be due to cystathionase deficiency, decreased pyridoxal phosphate affinity, or homocysteine methyltransferase deficiencies
  • Hyperuricemia

    "Excess urine," or uric acid, in the "blood."

    • Hyper (Greek) - Over, beyond, excess
    • Ouron (Greek) - Urine
    • Haima (Greek) - Blood
  • Associated with LeschNyhan syndrome, drug toxicity (pyrazinamide, thiazide, furosemide, niacin, cyclosporine), tumor lysis syndrome, and von Gierke disease
  • Ketonuria

    The presence of "ketones" in the "urine"

  • Nuria indicates an excess of a substance in the blood
  • Natriuretic peptide

    Peptide which induces "sodium" loss via "urine". Includes atrial natriuretic peptide which is "digested" and released by heart in response to increased blood pressure.

  • Atrial natriuretic peptide
  • Brain natriuretic peptide
  • ANP is the functional opposite of aldosterone
  • Paraaminohippuric acid

    A organic compound that is "colorless" and "pungent," yet "acidic."

    • Para (Greek) - Along, side, beside, near, against, contrary to
    • Ammoniakos (Greek) - Belonging to Ammon
    • Hippos (Greek) - A horse
    • Ouron (Greek) - Urine
    • Acidus (Latin) - Relating to acid
  • Diagnostic organic compound used to estimate renal plasma flow
  • Paroxysmal nocturnal hemoglobinuria

    The presence of "sphere" shaped proteins containing "blood" in the "urine" that is "sudden onset" at "night"

  • Rare hereditary disorder with complement induced intravascular hemolysis due to CD55 and CD59 receptor deficiencies
  • MarchiafavaMicheli syndrome, me is a misnomer presented with hemoglobinuria in the morning because of increased acidity when sleeping which leads to increased activation of the complement system
  • Polyuria

    Abnormally increased urine output. To make "urine" "many" more times than baseline

  • Seen in diabetes mellitus, central diabetes insipidus (lack of VasopressiDH), nephrogenic DI (Improper response to ADH), and patients taking diuretics among other conditions
  • Proteinuria

    The presence of "compounds composed of amino acids" in the "urine"

    • Protein (English) - A compound composed of amino acids
    • Ouron (Greek) - Urine
  • Seen in nephrotic syndrome

  • Urate crystal

    "Clear ice" rocks formed from urea, the main component of "urine."

  • Deposition of urate crystals commonly manifests as gout or tophi
  • Urate crystals are needleshaped and are negatively birefringent (yellow under parallel light and blue under perpendicular light)
  • Uremia

    Excessive amounts of "urea" in the "blood."

  • Uremia is the U of the MUDPILES mnemonic, and is therefore a cause of increased anion gap metabolic acidosis
  • In 1851, E.T. Frerich described clinical uremic syndrome and suggested that a toxicity was the mechanism of it cause. It was in 1856 that J. Picard developed a sensitive method to reproducibly measure blood urea. He was able to detect a 40% decrease of urea concentration between the renal artery and the renal vein. This work solidified the fact that renal failure coincided with an increase in blood urea. It was J. Picard with E.T. Frerich's work that made the term uremia popular
