Description of intervention(s) / exposure
This research retrospectively attempts to compare demographic characteristics, clinical presentations, and urodynamic findings between two age groups of detrusor overactivity with detrusor underactivity (DO-DU) patients: those younger than 70 years and those aged 70 years or older. This research is collecting data using a retrospective approach from medical records, absent any direct patient involvement. An approximate total of 250 patients diagnosed with DO-DU, who underwent multichannel urodynamic testing at a single center from 2012 to 2023, were included in this study. Patients were divided into two groups: the “Younger” group (aged less than 70 years) and the “Older” group (aged 70 years or older). We compared demographics, number of risk factors considered to affect bladder function, clinical presentations, and urodynamic findings between these two groups using univariate statistical analysis.

Statistical methods / analysis
The distribution of baseline characteristics, clinical symptoms, and urodynamic parameters were compared between patients under the age of 70 years and those greater than or equal to 70 years. Chi-square test was used for comparing proportions, and Wilcoxon rank sums were calculated for continuous and ordinal data. Statistics were conducted using STATA version 15.1, developed by StataCorp in College Station, TX, USA. P-value of 0.05 was used to denote statistical significance.
