What is it about?

Kidney stones are most commonly present in elderly males. However when looking at trends of this disease, we found that the rate of kidney stones in males is stable however the rate in females is increasing, specially in women age 20-39. The rate of kidney stones in young women has doubled in the last decade.

Why is it important?

Kidney stones are more common in systemic conditions associated with the metabolic syndrome, such obesity, diabetes and hypertension. The theories behind the formation of kidney stones at the cellular level mimic what occurs during vascular calcification when cellular function is altered due to hypoxia and rective oxygen species.

Perspectives

This publication opens the doors to interesting theories on the formation of kidney stones. The rapid increased of kidney stones observed in women of child bearing age is concerning. The rate of obesity in women seems to parallel our findings. However, other factors perhaps socio-economic, access to health care should be considered. Interestingly, our cohort of women over 60 had a stable rate of kidney stones compared to those under 59 years of age. Perhaps access to medical care is a factor that should be considered in this multifacetic disease.
