CALCIUM OXALATE MONOHIDRATE No-papillary or of Cavity

Minority components

Hydroxyapatite (HAP)

Organic Matter

Anhydrous Uric Acid (AUA)

Outline of the internal structure

Anchorage point:

NO

Porous Core

Calculi type:

Formed in renal cavity

Compact Core

Characteristic

Localization:

 Renal cavity with low urodynamic efficacy

Formation conditions:

  • Inhibitors deficiency

Recommended treatment:

  • Increase liquid ingestion
  • Use crystallization inhibitors (citrate or phytate)
  • Control the urinary Organic Matter (glomerulonephritis, hypertension, diabetes, etc.)

Notice:

    • Diminish the urinary pH below 6.0 in presence of HAP
    • Increase the urinary pH above 5.5 in presence of AUA
