We assessed the relationship between the type of passive urethral resistance relation (PURR) and prostatic histology in 28 patients with benign prostatic hyperplasia (BPH), who underwent transurethral resection of the prostate. PURR was classified into three types according to pressure-flow plots, and resected specimens were analyzed by quantitative morphometry. Patient age, prostatic volume and the area densities of each histological component did not show significant differences among the three groups. However, there was a trend to correlation between prostates with a high glandular component and urethral compliance. Further studies of larger populations are needed to validate this assumption.
