[Limit of short Pad-Test and questionnaires about urinary incontinence evaluation after prostatectomy]

Clinical study among men suffering from postprostatectomy urinary incontinence comparing the short term Pad-Test to urinary symptom questionnaires.

From June 2006 to November 2008, 16 patients presenting a urinary incontinence after prostatectomy have been operated by I-Stop® TOMS male sling. The incontinence has been evaluated by analyzing data from the short Pad-Test, ICIQ and SF36 questionnaires. This evaluation has been done before surgery (Day 0) and 90 days after (Day 90). The short term Pad-Test was recommended by the International Continence Society. The analysis between the values has been appreciated by Kendall ratio with a significant value, for the independence test, if smaller than 0.05.

We can't demonstrate any significant evolutive correlation of the short term Pad-Test and ICIQ or SF36 questionnaires results between Day 0 and Day 90. At Day 0, there is no significant link between short-term Pad-Test and ICIQ or SF36 questionnaires results.

The absence of correlation between the two evaluations before surgery confirms the interest of a double evaluation, objective and subjective. The short-term Pad-Test is easy to perform but presents a limited variability of the measure and a lack of precision in leakage detection. Nevertheless, there is a bias of selection in the recruited population who suffered from a minor or moderated urinary incontinence after prostatectomy, according to Stamey standards. The authors propose to prefer 24 hours Pad-Test which evaluate the leakage on a larger period of time.
