Summary
Urethral pressure profilometry, cystourethroscopy, and voiding cystourethrogram were evaluated for diagnosing urethral diverticula. While profilometry confirmed diverticula, it also showed pressure changes in other conditions, not altering the surgical plan.
Area of Science:
- Urology
- Diagnostic Imaging
- Gynecology
Background:
- Urethral diverticula present diagnostic challenges.
- Accurate evaluation is crucial for effective management and surgical planning.
Purpose of the Study:
- To compare the diagnostic value of urethral pressure profilometry (UPP) against cystourethroscopy and voiding cystourethrogram (VCUG) for urethral diverticula.
- To assess the role of UPP in surgical management decisions.
Main Methods:
- Twelve women with suspected urethral diverticula underwent initial evaluation with cystourethroscopy and VCUG.
- All participants subsequently underwent urethral pressure profilometry.
Main Results:
- Urethral diverticula were confirmed in 9 out of 12 patients by cystourethroscopy and VCUG.
- UPP identified pressure depressions or biphasic curves in all confirmed diverticula cases.
- UPP also showed similar pressure changes in Skene duct cysts and genuine stress incontinence, and identified incontinence in one diverticula patient.
Conclusions:
- Cystourethroscopy and VCUG are satisfactory for diagnosing urethral diverticula and guiding surgical treatment.
- UPP can confirm diverticula but may yield false positives in other conditions.
- UPP did not alter the surgical plan for diverticula but aided in planning additional incontinence surgery for one patient.
