Re: Risk of Urinary Tract Cancers Following Kidney or Ureter Stones

Re: Risk of urinary tract cancers following kidney or ureter stones.

BACKGROUND A relationship has been suggested between kidney or ureter stones and the development of urinary tract cancers. In this study, a population-based cohort of patients hospitalized for kidney or ureter stones in Sweden was followed for up to 25 years to examine subsequent risks for developing renal cell, renal pelvis/ureter, or bladder cancer. METHODS Data from the national Swedish In...

Re: Caffeine intake and the risk of kidney stones.

BACKGROUND Although caffeine intake may increase urine calcium excretion, caffeine-containing beverages have been associated with a lower risk of nephrolithiasis. OBJECTIVE We sought to determine the association between caffeine intake and the risk of incident kidney stones in 3 large prospective cohorts. DESIGN We prospectively analyzed the association between intake of caffeine and incide...

Dietary influences on urinary oxalate and risk of kidney stones.

Calcium oxalate is the most common constituent of kidney stones. Increases in urinary oxalate increase risk of calcium oxalate supersaturation more than increases in urinary calcium, as the physiological level of oxalate is about one-fifth to one-tenth that of urinary calcium. Urinary oxalate derives from two sources: endogenous synthesis and diet. Endogenous synthesis is proportional to lean b...
