What the study found

In this Swiss adult cohort, ultrasound-detected kidney stones were present in 5.6% of participants, and 4.3% developed new stones over 3 years. The authors report that the prevalence was lower than in North America but higher than in Asian populations.

Why the authors say this matters

The authors conclude that these data will help inform prevention strategies. The findings indicate that kidney stone patterns and associated factors in Switzerland add information where European data are described as scarce.

What the researchers tested

The Swiss Kidney Project on Genes in Hypertension (SKIPOGH) is a multicenter cohort of 1,128 adults recruited from Lausanne, Geneva, and Bern between 2009 and 2012. Participants had renal ultrasound at baseline, completed a standardized questionnaire, and returned for follow-up 3 years later; the researchers used logistic regression to examine factors associated with kidney stone prevalence and new stone formation.

What worked and what didn't

At baseline, diabetes mellitus, family history of kidney stones, and higher serum creatinine were associated with prevalent kidney stones. For 3-year incidence, active smoking, lower physical activity score, and a personal history of kidney stones were associated with new stones. The abstract does not report other variables as associated with prevalence or incidence.

What to keep in mind

The summary provided does not describe limitations beyond noting that European data are scarce. The results come from one Swiss cohort, so the abstract does not state how far the findings extend beyond this population.

Key points

  • Ultrasound-detected kidney stones were present in 5.6% of participants overall.
  • New kidney stones appeared in 4.3% of participants over 3 years.
  • Diabetes mellitus and family history were linked to prevalent kidney stones.
  • Active smoking, lower physical activity, and a personal history of stones were linked to new stones.
  • The authors say the prevalence was lower than in North America and higher than in Asia.
