Abstract

Aims: To investigate the feasibility and reliability of the seven-day pad test (7DPT), the correlation between 7DPT and 24-hour pad test (24HPT), and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) questionnaire, and the different categorization by the severity of each pad test. Pad weighting tests have been recommended in the evaluation of post-radical prostatectomy urinary incontinence severity, being considered the 24HPT gold standard. Some authors consider that the longer the testing, the better assessment. We propose a self-filled pad weight, the 7DPT.

Methods: A prospective study of incontinent male patients after radical prostatectomy. We carried out the study in two phases. All patients underwent urodynamic study. The first phase evaluated the feasibility and reliability of 7DPT. The second evaluated the correlation between 7DPT, 24HPT, and ICIQ-SF questionnaire in a larger sample.

Results: First phase: 32 patients were recruited. Test-retest reliability was excellent, with good agreement between mean 7DPT and 24HPT. The number of pads and mean 7DPT showed a good correlation. Second phase: 72 patients were screened, 51 (71%) met inclusion criteria. Mean 7DPT and 24HPT showed a strong association. Mean 7DPT and 24HPT correlated moderately with ICIQ-SF score. 7DPT and 24HPT agreement with ICIQ-SF groups was slight. As 7DPT captures better days with maximum urinary leakage, up to 12 patients would have been misclassified according to 24HPT (number need to treat for 7DPT was seven).

Conclusions: 7DPT is a feasible and reliable tool to evaluate post-radical prostatectomy urinary incontinence, with a strong correlation with the 24HPT and moderate with the ICIQ-SF.
