Statin usage may defer the development of lower urinary tract symptoms (LUTS) and benign prostatic enlargement (BPE) by up to seven years. The Olmsted County study, a huge cohort study that has been running in Minnesota for many years, has produced several important urological papers. The Olmsted County database was used to carry out a retrospective study of almost 2,500 men, aged 40-79 years, from 1990 to 2007. 'This study has significant flaws, most notably that it is a retrospective cohort study rather than a randomised controlled trial. Furthermore, the Olmsted County population is a largely affluent Caucasian community, and therefore it is unclear as to whether these results would apply across other ethnic and socio-economic groups. However, the results are interesting at a time of ever increasing statin prescription. There is a potential for vast public health benefit if the findings of this study were reproduced across our at-risk population.'
