| Outline of Final Research Achievements |
According to the types of stone composition, the severity of urolithiasis and abnormalities in urine constituents were examined by the number of metabolic syndrome (MetS) traits (obesity, hypertension, dyslipidemia, and diabetes) using clinical data from patients with urolithiasis enrolled in the 6th Nationwide Survey on Urolithiasis in Japan conducted in 2005. In patients with calcium oxalate (CaOx) stone, MetS trait clustering is associated with greater severity of the disease and increased urinary calcium excretion. These results suggest that CaOx stone disease should be regarded as a systemic disorder linked to MetS. Improvement of MetS was thought to have the potential to prevent CaOx stone, which accounts for most of urolithiasis. I presented these results at American Urological Association 2017 and am submitting a paper. Indeed, for obese patients, we planned to examine whether weight loss prevents urolithiasis, but we are recruiting obese patients because of lack of cases.
