Family and Personal History
Scientific research suggests people are at a higher risk to develop kidney stones if they or someone in their immediate family has previously had a stone. In fact, one 1999 study on kidney stone patients in Italy showed that 22% of their parents and 14% of their siblings had at least one kidney stone in the past. If a person has gout in their family, they are more susceptible to stones. Some studies indicate that 45% of all incidences of kidney stones are due to genetic factors.
