Phenotyping the detrusor underactivity: Is it more important than categorizing the symptomatic presentation of detrusor underactivity?

Phenotyping by either etiologies or covariates and by syndromic presentations is not easy. Due to the aging features, multiple factors are needed during interpretation of the categorized phenotypes. Considering the advantage of the clinical benefit from the patient's viewpoint, categorization of syndromic symptomatic presentation using multiple validated tools including patient-reported outcomes is needed.
