LUTS cause profoundly negative impacts on their quality of life. Pathophysiology of LUTS is multifactorial, and recently, bladder ischemia and metabolic syndrome have been suggested as etiological factors. To evaluate chronic hyperlipidemia on bladder function, we examined the functional and histological changes of the bladder in myocardial infarction\u2010prone Watanabe Heritable Hyperlipidemic (WHHLMI) rabbits.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>20\u2010 to 24\u2010month\u2010old WHHLMI rabbits and age\u2010 and sex\u2010matched control rabbits were prepared. Bladder functions were evaluated using cystometrograms and functional experiments with isolated bladder specimens. Histological studies of bladder and internal iliac arteries were performed with hematoxylin and eosin staining. The bladder was also stained immunohistochemically with mouse monoclonal S\u2010100 antibodies and sheep polyclonal calcitonin gene\u2010related peptide (CGRP) antibodies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In cystometric examination, WHHLMI rabbits showed significantly shorter micturition interval, smaller voided volume with non\u2010voiding contractions, and lower micturition pressure, as compared to control. The functional experiments showed that carbachol\u2010 and electrical field stimulation\u2010induced contractions were significantly decreased in WHHLMI rabbits than those in control. In WHHLMI rabbits, cross\u2010sections of internal iliac arteries showed significant atherosclerosis and thickening of media. Bladder showed thinner urothelium and decreased smooth muscle area in WHHLMI rabbits, as compared to control. WHHLMI rabbits showed a significant decrease in S\u2010100 protein positive neurons, and an increased number of CGRP positive neurons.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study demonstrated that WHHLMI rabbits showed detrusor overactivity with decreased detrusor contraction.
