Aims:
Recently, [Brown et al Neurourol Urodyn. 36:1151-1154, 2017] reported a remarkable study regarding detrusor underactivity (DU) by categorizing the possible phenotypes. Although this study presents novel findings on the possible phenotypes, several points need to be clarified further for a better understanding.
Methods:
The methodology, especially regarding categorizing the phenotypes has been reviewed and comments have been added for better understanding of their study.
Results:
To better understand novel results of their study, several points have to be considered, which include cluster analysis and categorization according to symptomatic presentations.
Conclusions:
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.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
