Decreased peak flow rate and a history of hypertension and/or diabetes are significantly associated with CKD in men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH), according to investigators in Seoul, Korea.

The findings, published in BJU International (2009; published online ahead of print), are based on a study of 2,741 men who presented with LUTS due to BPH. Of these, 161 (5.9%) were initially classified as having CKD.
