From the Guidelines
The notation "CA OXALATE CRYS, UR SED QL 3+" indicates a significant amount of calcium oxalate crystals in the urine, suggesting hyperoxaluria or hypercalciuria, and requires immediate attention to prevent kidney stone formation. This finding is concerning because calcium oxalate crystals can lead to kidney stone formation, which can cause severe pain, urinary tract obstruction, and other complications. According to the American College of Physicians guideline 1, patients with recurrent nephrolithiasis should increase their fluid intake to at least 2 L of urine per day to prevent stone recurrence.
Key Recommendations
- Increase fluid intake to at least 2-3 liters of water daily to dilute the urine and reduce crystal formation 1
- Reduce oxalate-rich foods (spinach, rhubarb, chocolate, nuts) and moderate calcium intake, as excessive calcium can increase urinary oxalate 1
- Maintain normal calcium consumption and limit intake of oxalate-rich foods, as recommended by the AUA guideline 1
- Medical evaluation is crucial to determine the underlying cause, which could include metabolic disorders, dietary factors, or certain medications
Underlying Causes and Complications
The presence of calcium oxalate crystals in the urine can be caused by various factors, including hyperoxaluria, hypercalciuria, metabolic disorders, dietary factors, or certain medications. Left untreated, persistent calcium oxalate crystals can aggregate and form painful kidney stones, leading to severe morbidity and mortality. Therefore, it is essential to address this issue promptly and make necessary lifestyle and dietary modifications to prevent kidney stone formation.

CA OXALATE CRYS, UR SED QL 3+ Explanation
- CA OXALATE CRYS refers to calcium oxalate crystals, which are a common component of kidney stones 2, 3, 4, 5, 6.
- UR SED QL 3+ is a urinalysis result indicating the presence of calcium oxalate crystals in the urine, with a quantity of 3+ suggesting a significant amount 6.
- The presence of calcium oxalate crystals in the urine can be an indicator of kidney stone disease or other underlying metabolic disorders 2, 3, 4, 5.
- Factors that contribute to the formation of calcium oxalate crystals include hypercalciuria, hypocitraturia, hyperoxaluria, and hyperuricosuria 3, 4, 6.
- Treatment options for preventing recurrent calcium oxalate stones include dietary modification, potassium-magnesium citrate, and thiazide or indapamide with potassium citrate 2, 3, 4, 5.
