Alkaluria
September 10th, 2020
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
