Summary
Bladder wall thickness in women with lower urinary tract symptoms is influenced by age and urodynamic factors. A thickened bladder wall is common, except in cases of hypersensitive bladder.
Area of Science:
- Urology
- Gynecology
- Medical Imaging
Background:
- Lower urinary tract symptoms (LUTS) are common in women.
- Bladder wall thickness (BWT) on ultrasonography may indicate underlying pathology.
- Understanding factors influencing BWT is crucial for diagnosis and management.
Purpose of the Study:
- To investigate demographic, anatomical, and urodynamic factors associated with BWT in female LUTS patients.
- To correlate BWT at different bladder regions (trigone, dome) with clinical and urodynamic parameters.
Main Methods:
- Retrospective analysis of 492 female patients with LUTS undergoing urodynamic study and ultrasonography.
- Inclusion criteria: normal urinalysis and urine culture.
- Patient groups included stress incontinence, detrusor overactivity, mixed incontinence, hypersensitive bladder, voiding difficulty, and normal urodynamics.
Main Results:
- Age, resting bladder neck angle, urethral mobility, and maximum urethral closure pressure correlated with BWT at the trigone and dome.
- BWT at the trigone correlated with BWT at the dome.
- Age and intravesical pressure at maximum flow were independent predictors of BWT.
Conclusions:
- Demographic, anatomical, and urodynamic factors significantly influence BWT in women with LUTS.
- Thickened BWT is a frequent finding in female LUTS, excluding hypersensitive bladder cases.
