Studies utilizing rodent models, including work in our laboratory, have shown prostate fibrosis to occur as a consequence of inflammation. However, the relationship between collagen content and inflammation in human tissue samples obtained from surgical treatment of benign prostatic hypererplasia\u00a0(BPH)\/LUTS has not to our knowledge been previously examined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Prostate tissue specimens from 53 patients (ages 47\u221288, mean 65.1) treated by open simple prostatectomy or transurethral resection of the prostate\u00a0for BPH\/LUTS were stained to quantitatively assess prostate inflammation and collagen content. Patients with prostate cancer present in greater than 5% of the surgical specimen were excluded. Prostate volume was determined from pelvic CT scan obtained within 2\u00a0years of surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Analysis of the data showed that inflammation was inversely correlated with collagen content (<jats:italic>r<\/jats:italic>\u2009=\u2009\u22120.28, <jats:italic>p<\/jats:italic>\u2009=\u20090.04).

by intense inflammation and low collagen content and it is this subgroup that appears most responsible for the inverse correlation of inflammation and
