Alkaluria

 
Bookmark

Overview

An increase in the urine pH suggests an abundance of base in the urine.
This is commonly a sign of infection with a urease-producing bacteria, which convert urea into the alkaline ammonia. Such urinary alkalinisation can result in the formation of struvite stones.
  • Causes of Alkaluria

  • Dietary - low carbohydrate diet
  • Urea-splitting bacteria - Proteus, Klebsiella, Pseudomonas, coagulase negative Staphylococcus
  • Metabolic alkalosis - alkaline ingestion, massive transfusion, dialysis, vomiting, diuretics, Cushing’s, Conn’s, 
  • Respiratory alkalosis - hyperventilation
  • Renal tubular acidosis
