#nephrology definition
- Ammoniuria — The urinary excretion of ammonia or ammonium ions, representing an essential clinical indicator of how the kidneys regulate systemic acid-base balance. In states of metabolic acidosis, its values increase significantly due to the amplification of compensatory renal ammoniogenesis, transforming ammonium excretion into a physiological barrier against blood pH decrease.
- Anuric — Suffering from anuria, characterized by the complete absence or severe pathological reduction of urine excretion (less than one hundred milliliters in 24 hours) due to acute renal failure or an obstruction in the urinary tract; (noun) a patient presenting this critical clinical picture.
