What are the risk factors for kidney stones?

Condition analysis:
Several factors increase the risk for developing kidney stones, including inadequate fluid intake and dehydration, reduced urinary flow and volume, certain chemical levels in the urine that are too high (eg, calcium, oxalate, uric acid) or too low (eg, citrate), and several medical conditions. Anything that blocks or reduces the flow of urine (eg, urinary obstruction, genetic abnormality) also increases the risk.

Instructions:
Uva ursi: Uva ursi is a herb that has been used to treat urinary and bladder conditions. It is also thought to lower the acid level in the urine and decrease kidney stone formation. Uva ursi acts as a diuretic, which helps you flush stones out. It may also have properties that help soften the stones and break them into smaller pieces that can be eliminated. Plus, it increases renal circulation, which is a bonus for kidney health.
