Abstract

OBJECTIVES:

The aim of this study was to determine whether self subjective assessment of urinary incontinence as perceived by female patients could replace the standard 1-hour pad test in clinical practice.

DESIGN:

Prospective cohort study.

SETTING:

District General Hospital, South West of England.

METHODS:

Ninety women awaiting surgical treatment for urodynamic stress incontinence were recruited. They underwent 160 pad tests; on each test women were asked to classify themselves on a four point scale into one category (0: totally continent to urine, 1: mild/occasional urinary incontinence (UI), 2: moderate UI, 3: severe UI), to complete the King's Health Questionnaire (KHQ) and carry out the standard International Continence Society 1-hour pad test. A pad gain >1 gm was considered a positive result.

MAIN OUTCOME MEASURES:

Women perception for severity of UI, 1-hour pad gain, KHQ scores.

RESULTS:

Self subjective assessment of UI (continent vs. incontinent) had good correlation (r = 0.88) with the pad test result (negative vs. positive), and correlated well with the KHQ scores (r = 0.79). Poor correlation was seen between the pad gain and the KHQ scores (r = 0.48) and between the pad gain and the self subjective assessment of UI scale (r = 0.48). The self subjective assessment of UI (incontinent vs. continent) had sensitivity 95.65% and specificity 93.33% to detect the pad test results (positive vs. negative).

CONCLUSION:

This study suggest that, in either the pre- or postoperative phase, simply asking a woman if she is continent for urine or not was as good as doing the pad test and correlated better with the patient quality of life.
