Kidney stone disease (nephrolithiasis) is a common urological condition with rising
global prevalence over the past three decades. Data support a correlation between
kidney stones and genitourinary malignancies, particularly renal cell carcinoma
(RCC), bladder cancer, and prostate cancer. This study examines epidemiological
and pathophysiological links between nephrolithiasis and these cancers, based on
extensive cohort studies and molecular insights. Bladder cancer, one of the most
common urinary tract malignancies, occurs more frequently in individuals with a
history of kidney stones, with significantly elevated odds ratios reported. Prostate
cancer, the most prevalent male malignancy, is also more common in stone formers,
especially with concurrent urinary tract infections. For RCC, the relationship
appears subtype-specific, with papillary RCC showing the strongest correlation.
Shared risk factors—such as obesity, metabolic syndrome, hypertension, poor diet,
tobacco use, age, and sex—contribute to both nephrolithiasis and cancer
development. Chronic inflammation and epithelial injury from recurrent stones
may create a carcinogenic environment in the urinary tract. However, Mendelian
randomization studies are not yet supportive of a direct causal relationship between
genetics, suggesting that environmental and physiological processes are more
central to the relationship. Finally, kidney stone disease may be a risk marker for
genitourinary cancer. Identification of this association is essential for prevention
and early detection in high-risk groups.
