Quantifying Female Incontinence with Particular Reference to the Urilos System

Abstract

An assessment of the Urilos System for quantifying urinary incontinence is presented. There was approximate reproducibility of urine loss measurements between nappies in the same pack but under- and over-recordings of up to 25 and 23%, respectively, were observed; when packs of nappies were compared there were differences of up to 68%. Thus, the Urilos System is not, as yet, sufficiently reliable for quantifying incontinence. Other methods of measuring incontinence objectively are discussed and the use of the daily bladder chart is commended.

Comparison between urinary diaries completed with and without intensive patient instructions

“…Several types of self-reporting urinary diaries have been designed, most at least provide a means of recording the number of episodes of voluntary and involuntary micturition [Wilson et al, 1980;Robb, 1985;Burton, 1984;Ouslander et al, 19861. Data is usually collected in 24 hour intervals with these periods further segmented into smaller time blocks to allow for determination of the frequency of diurnal and nocturnal voluntary micturition.…”

Clinical Relevance of Urethral Stress Profile Using Microtransducers after Surgery for Stress Incontinence in Females

“…This test is simple, cheap and noninvasive. Although it does not allow one to quantify the losses exactly [32], it has the advantage of being able to record the losses under the conditions under which the patient usually loses urine.…”

“…The Urilosmeter was designed to quantify urinary losses in an incontinent patient [15,32]. It consists of a disposable nappy to which electrode strips containing dry electrolytes are attached.…”

The use of perineal pad testing to assess urinary incontinence

“…Stanton and Ritchie 10 described clinical and technical assessments of pad weighing and observed that, when a measured quantity of urine was used, the difference between two pad weights was 13%. Wilson et al 11 assessed the 'Urilos System' and found that the measurement of urine loss between pads from different packs could vary by up to 58%. Under-and over-recording of up to 25% and 23%, respectively, were also observed.…”
