Renal stones: risk factors
Renal stones: risk factors
Risk factors- dehydration
- hypercalciuria, hyperparathyroidism, hypercalcaemia
- cystinuria
- high dietary oxalate
- renal tubular acidosis
- medullary sponge kidney, polycystic kidney disease
- beryllium or cadmium exposure
Risk factors for urate stones
- gout
- ileostomy: loss of bicarbonate and fluid results in acidic urine, causing the precipitation of uric acid
Drug causes
- drugs that promote calcium stones: loop diuretics, steroids, acetazolamide, theophylline
- thiazides can prevent calcium stones (increase distal tubular calcium resorption)
