We aimed to evaluate the relationship between serum testosterone levels and kidney stone prevalence in men. We examined cross-sectional data from 3234 men who participated in a health examination (2010–2020). A full metabolic work-up, including serum testosterone levels, was performed. Combined ultrasonography with KUB radiography was used for stone detection. The participants’ median age and testosterone concentration were 53.0 years and 4.7 ng/mL, respectively. A total of 178 men had kidney stones. A cutoff value for determining the presence of kidney stones was a testosterone concentration <3.33 ng/mL ng/mL. After adjusting for confounders, only age and a testosterone concentration <3.33 ng/mL were significantly related to the presence of kidney stones. However, body mass index, blood pressure, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, creatinine, blood urea nitrogen, HbA1c, uric acid, hs-CRP, calcium, aspartate transaminase, alanine aminotransferase, and albumin were not significantly and independently related to kidney stones. The odds ratios (95% confidence intervals) for kidney stones according to age and testosterone concentration <3.33 ng/mL were 1.029 (1.010–1.04) and 1.655 (1.071–2.556), respectively. Our study revealed that the prevalence of kidney stones significantly and independently increased when the serum testosterone was less than 3.33 ng/mL in men.

AbstractThere are two complementary approaches to thermodynamics: an empirical, phenomenological representation of macroscopic states and a model-based, statistical-mechanical representation of microscopic states. If only a few energy transformation steps are involved, macroscopic quantities such as energy and entropy can be estimated without ambiguity, and often the associated microscopic states are well characterised.

AbstractThe effective dose represents the overall internal radiation exposure to the whole body when exposed to radiation sources. This study aims to compare conventional and software-aided methods to derive the effective dose.
