title: Stress incontinence in women under 50: does urodynamics improve surgical outcome?
abstract: The aim of the study was to determine whether urodynamic testing improves the outcome of retropubic surgery in women aged 50 or younger. A retrospective study was undertaken of 212 women aged 50 or younger who underwent retropubic surgery at a medical school-affiliated hospital between February 1991 and July 1997. Excluded were patients with prior retropubic urethropexy and known low urethral closure pressures. The surgery was performed by one urogynecologist and two urologists. The minimal evaluation by the urogynecologist was a focused incontinence questionnaire, pelvic neurologic examination, pelvic floor grading, cough stress test, urinalysis, postvoid residual, cotton swab test and supine empty stress test. Full urodynamics consisted of uroflowmetry, subtracted cystometry, urethral closure pressure, cough leak-point pressure and cystourethroscopy. Subjective postoperative follow-up at 14 years was by annual questionnaire. The urogynecologist's patients were in group I (95 women with full urodynamic studies) and group II (36 women with minimal testing). The urologists' patients were in group III (81 women with a very minimal workup and cystourethroscopy). A review of seven variables revealed no difference between the groups. In terms of cured, improved and failed, there was also no difference in outcome. There was a difference in postoperative voiding problems (though not stress incontinence) in group III compared to group I (P= 0.005) and group II (P=0.002). Our conclusion was that all women with stress incontinence should undergo a careful minimal evaluation. In women aged 50 or younger urodynamic studies may be avoided unless there is significant stress incontinence, complex symptoms, a positive supine empty stress test, marked prolapse, or a history of prior retropubic urethropexy.
