People with kidney stones are twice as likely than others to suffer kidney failure later in life and have higher risks of recurrent stones, chronic kidney disease, and heightened creatinine levels. Regular follow-ups can aid in the timely detection of kidney damage. Prevent kidney stones by lowering your sodium intake and staying hydrated. Young women need to be more cautious.
Kidney stones are linked to an increased risk of kidney problems later in life. Kidney stones are quite common but are preventable. Yet, their connection to later-life renal failure has long been unclear.
Do Kidney Stones Lead To Kidney Problems?
Canadian and American researchers explored the link between kidney stones and kidney problems later in life. The scientists tracked over 3 million patients for an average of 11 years. They used hospital records to identify episodes of kidney stones and subsequent development of chronic kidney disease, kidney failure, or raised creatinine levels.
There were 23,703 patients who endured recurring kidney stones during the follow-up period, where 4 percent went on to develop late-stage chronic kidney disease, 0.3 percent experienced sustained doubling of creatinine levels, and 0.2 percent developed kidney failure — compared with those without a history of kidney stones.
The risk of developing later-life kidney problems as a result of kidney stones was greater in women than in men and among younger individuals, compared with those over the age of 50.
The researchers suspect that the calcification process involved in the formation of kidney stones may be the link between kidney stones and later-life kidney problems.
The researchers concluded that it is “a graded association between episodes of kidney stones and the risk of adverse renal outcomes.” Further research “should be aimed at determining the mechanisms explaining this association and assessing the optimal way to prevent kidney stones in the general population, especially young women.”
How Should You Reduce Your Risk?
A previous study found that individuals who develop kidney stones are twice as likely to suffer kidney failure, compared with individuals without a history of kidney stones. The researchers looked at data over an 11-year period and found that kidney stone patients had a higher risk of kidney failure and women under the age of 50 had four times greater risk to suffer kidney failure later on.
Researcher Todd Alexander said, “I think what these results tell me is that we should be screening those with a history of kidney stones for risk factors for the development of kidney disease. I am not surprised by these findings, because when you are passing a stone through a kidney, there is definitely the potential for permanent damage.”
The researchers suggest that half of those who develop kidney stones will go on to develop recurring kidney stones. Marcello Tonelli, co-researcher, added, “It’s important to note that the vast majority of people with kidney stones won’t develop permanent kidney damage. But a few will, and that’s why it’s important for people with stones to get proper follow-up care — to reduce their risk of another stone, and to detect kidney damage if it has occurred.”
To decrease the risk of kidney stones people should lower their sodium intake, stay well hydrated, and take certain medications if required.
