Effect of diabetes mellitus on lower urinary tract symptoms and dysfunction in patients with benign prostatic hyperplasia.

This article reviews the recent literature on men with diabetes mellitus (DM) and concomitant lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). Diabetes is reported to be associated with greater BPH symptom severity. Men with non-insulin-dependent diabetes had the highest median annual prostate growth rate compared with those who had other metabolic disease. Urodynamic evaluations in the reviewed studies were absent. Extensive diagnostic evaluations with urodynamics in our outpatient department revealed that patients with LUTS suggestive of BPH and with concomitant DM hardly differed from those without DM.
