OBJECTIVE: To describe the results of urodynamic study in women with pure stress urinary incontinence symptoms, including the characteristics of the overactive detrusor.
No other clinical assessments were taken into account.
MATERIAL AND METHODS: A retrospective study in women with urinary incontinence consecutively evaluated by urodynamic study. From a total of 710 women, only 108 (15%) with pure stress urinary incontinence symptoms were selected. Women with prior urinary incontinence surgery, pelvic organ prolapse (stage ≥iii), pelvic radiotherapy, using medication active on the lower urinary tract and neurological diseases were excluded. Infusion rate was 70ml/min. Detrusor overactivity was induced only by cough. A standardized cough stress test with progressive cough intensity was carried out.
RESULTS: Reference urodynamic values for stress incontinent women are described. Urodynamic stress incontinence was observed in 79 women (73.1%), detrusor overactivity in 4 (3.7%) and mixed urodynamic diagnosis in 15 (13.8%). Test was inconclusive in 10 patients (9.2%). Two women had detrusor overactivity incontinence (1.9%). One patient had detrusor overactivity induced by cough without urodynamic stress incontinence (0.9%). There was an association between detrusor overactivity and nocturia ≥2 (P=.002; odds ratio: 3.74; 95% confidence interval: 1.22-11.39). One woman had a bladder outlet obstruction (0.9%).
CONCLUSIONS: In women with pure stress urinary incontinence, without knowing the outcome of other clinical assessments, urodynamic study can provide useful information to define the proper therapy.
