Hypochloruria (lowering of chlorine in the urine) develops due to the release of an increased amount of chlorine with sweat, vomit and through the intestine. Hypochloruria, as a rule, accompanies hypochloremia in diarrhea and vomiting of various etiologies, with feverish diseases. With pneumonia as a result of the so-called "dry" chlorine retention (due to the release of chlorine to the tissues), its content in the urine decreases. Cardiovascular decompensation with edema development, inflammatory effusions, edema formation in kidney diseases are accompanied by a "wet" chlorine retention in the body (due to the transition of chlorine to the extracellular fluid), and hypochloruria also occurs.

Violation of the processes of endocrine regulation of water-electrolyte metabolism with increasing function of the adrenal cortex and pituitary gland can be accompanied by hypochloruria with hyperchloremia as a result of reverse absorption of chlorine in the renal tubules.

Hyperchloruria (increase of chlorine in urine) as a physiological phenomenon is possible with significant introduction of sodium chloride into the body. As a pathological phenomenon, hyperchlororia occurs less frequently and accompanies the processes of resorption of edema, exudates and transudates, while it occurs simultaneously with hyperchloremia. The recovery period for infectious diseases, pneumonia is accompanied by the return of chlorides and hyperchloria.

There is no direct relationship between the chlorine content in the blood and its excretion in the urine.
