Incontinence Special Tests

You may require additional test if incontinence still presents after treatment. Urologists will perform urodynamic, endoscopic, and imaging tests.

Special tests for Incontinence diagnosis

If previous treatment fails, then need specialized tests to get a more extensive assessment of the lower urinary tract.

Postvoid residual volume (PRV) - This test requires catheterization or pelvic ultrasound. The patient is requests to voids just before the PRV measurement. Examine the initial void for hesitation, strain, or interrupted flow. A PRV of less than 50 mL indicates adequate bladder emptying (normal). If repeated measurements of 100 to 200 mL or higher indicates inadequate bladder emptying. Repeated measurements may be necessary to confirm the result.

Urodynamic Testing - Cystometry may be useful to assess the anatomic and functional status of the bladder and urethra. The cystometer measures the pressure and capacity of the bladder; it can thus assess the function of the detrusor muscle.

Uroflowmetry helps to diagnose any abnormal voiding patterns. Urethral pressure profilometry measures the resting and dynamic pressures in the urethra.

Endoscopic Tests - Cystoscopy helps to examine the presence of bladder lesions (e.g., cysts) and any foreign bodies.

Imaging Tests - X-rays and ultrasound may be useful to assess physical conditions associated with urinary incontinence. Images of the lower urinary tract before, during, and after voiding may help to examine the anatomy of the urinary bladder and urethra.
