The diagnostic value of cystourethrography for urinary incontinence remains debated.
Specific radiologic landmarks are thought to indicate stress urinary incontinence.
Purpose of the Study:
To assess the reliability of 5 radiologic landmarks in diagnosing stress urinary incontinence.
To compare these findings between patients with stress urinary incontinence and idiopathic detrusor instability.
Main Methods:
Review of 83 cystourethrograms from patients with stress urinary incontinence or idiopathic detrusor instability.
Interpretation of 5 specific radiologic landmarks by three independent radiologists.
Analysis of inter-observer agreement and differences in landmark distribution.
Main Results:
Inter-observer agreement for the 5 landmarks varied significantly, with a lack of identification or agreement ranging from 19.3% to 54.2%.
No statistically significant differences were found in the distribution of these radiographic characteristics between the stress urinary incontinence and idiopathic detrusor instability groups.
Conclusions:
The evaluated radiologic landmarks show poor inter-observer reliability.
Cystourethrography findings do not reliably differentiate between stress urinary incontinence and idiopathic detrusor instability based on these landmarks.
