Urodynamics in women with stress and urge incontinence.

Subtracted bladder pressure recording is the ideal method to diagnose bladder instability in supine and erect positions. Uroflowmetry demonstrated higher peak flow rates in our stable bladder group. Lateral cystourethrography showed a higher degree of urethral hypermobility in the same group. We believe that cystometry with subtraction is still the cornerstone in the evaluation of these patients. Uroflowmetry and lateral cystography may add some information and deserve further investigation in a large number of patients. Intravesical pressure alone, external urethral sphincter electromyography, and static urethral pressure profilometry were of no value in the evaluation of our patients.
