In medicine, urolithiasis if the "formation of stones in any part of the urinary tract, usually in the kidney; urinary bladder; or the ureter."[1]
Classification
Etiology/cause
High calcium diets are paradoxically associated with reduced urolithiasis.[2] This may be due to calcium in the diet reducing hyperoxaluria.
- Hypercalcuria - >140 mg/gm of urine creatinine or >4 mg/kg of body weight
- Hyperoxaluria - >40mg in 24 hour urine. May be primary or secondary to disorders such as inflammatory bowel disease
- Hypocitruria
- Uric acid
- Struvite
- cystine
Treatment
Prevention
Chlorthalidone reduces recurrence of calcium oxalate stones.[3][4]
