Comparisons of Phasic and Terminal DO

Completed

• Conditions: Detrusor Overacitivity

• Registration Number: NCT06793046
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

Overactive bladder is a common issue among women of childbearing age, regardless of their childbirth experience. Some of these women may exhibit detrusor overactivity in urodynamic studies. Excluding detrusor overactivity caused by neurogenic bladder, the International Continence Society defines two types of idiopathic detrusor overactivity: phasic and terminal. Although many studies have explored overactive bladder and detrusor overactivity under different conditions, no literature directly compares these two types of detrusor contractions. Therefore, we aim to compare phasic and terminal detrusor overactivity in women with lower urinary tract dysfunction. Between July 2009 and December 2023, medical records of all women with lower urinary tract symptoms who underwent urodynamic studies in the urogynecological department of a medical center were reviewed. The medical records of phasic or terminal detrusor overactivity were selected for comparison (N=290). Those with phasic and terminal detrusor overactivity were excluded (N=21).

Detailed Description

Hypothesis / aims of study Detrusor overactivity (DO) can be classified into phasic or terminal ones. However, to our knowledge, clinical and urodynamic differences between phasic or terminal DO have never been reported. Therefore, the objective of this study is to elucidate the above differences.

Study design, materials and methods Between July 2009 and December 2023, medical records, including urodynamic data, bladder dairy data, and questionnaires, including patient perception of bladder condition, urgency severity scale, overactive bladder symptom score, urogenital distress inventory, incontinence impact questionnaire and King's health questionnaire, of all women with lower urinary tract symptoms who underwent urodynamic studies in the urogynecological department of a medical center were reviewed. The medical records of phasic or terminal DO were selected for comparison. Those with phasic and terminal DO were excluded.

STATA software was used for statistical analysis. Wilcoxon rank sum test or chi-square test were used for statistical analysis, as appropriate. A p \< 0.05 was considered statistically significant.
