Prevalence and urodynamic characteristics of detrusor overactivity with impaired contractility in the community-dwelling elderly with non-neurogenic lower urinary tract symptoms: Is it from a single or two independent bladder dysfunctions?

PURPOSE: To identify the prevalence of detrusor overactivity with impaired contractility (DOIC) in the community-dwelling elderly and explore whether it is from a single or two independent bladder dysfunctions. MATERIALS AND METHODS: ), and bladder voiding efficiency for voiding function. RESULTS: and worse voiding functions than those with DOIC, although some parameters did not reach statistical significance. CONCLUSIONS: It seems that DOIC is developed from a coincidental combination of two independent DO and DU in men. In contrast, DOIC is likely to be an intermediate step during the process of progression from DO to DU in women.
