LUTS represents a cluster of chronic urinary symptoms, including disorders of storage and emptying. In our study, the authors measured the severity of LUTS using a validated questionnaire, and LUTS were categorized as voiding and storage symptoms. After adjustment for prostate volume and age, the elasticity of the prostate was independently associated with voiding symptoms but not with storage symptoms; age was the only independent factor for storage symptoms. Loss of elasticity of prostate might reflect the inflammatory change and functional deterioration of lower urinary tract. However, the exclusive association between the elasticity of prostate and voiding symptoms indicates the mechanical effect of a stiff prostate on urinary flow.
