Kidney Cancer Linked to Kidney Stones

A kidney stone is a hard object that is made from chemicals in the urine. But can be found at any point in your urinary tract. The urinary tract includes the kidneys, ureters, bladder, and urethra. Not all kidney stones are made up of the same crystals.

Patients with a history of kidney stones are at significantly higher risk of renal cell carcinoma (RCC) and transitional cell carcinoma (TCC), according to the findings of a meta-analysis presented at the 2014 Kidney Week meeting.

The meta-analysis, by Wisit Cheungpasitporn, MD, of Mayo Clinic in Rochester, Minn., and colleagues, included 7 studies. A history of kidney stones was associated with a significant 76% increased risk of RCC and a 2.1 times increased risk of TCC.

In subgroup analyses, the risk of RCC associated with stones was significant only in male subjects. The researchers concluded that their findings may impact clinical management and cancer surveillance. Our kidney disease hospital email kidneyhospitalabroad@hotmail.com
