P-Mate™, a new device allowing women to urinate in the standing position: urodynamic and satisfaction assessment

Abstract

Urodynamic parameters and satisfaction were recorded after micturition in the seated position versus the standing position with a single-use device (P-Mate) in healthy women. Healthy adult women were recruited. Eligibility criteria were: no past urological history and no urological symptoms. Volunteers were given four P-Mates to use during a week and a satisfaction questionnaire to fill. After this trial week, they were invited to perform four flowmetries, two in the seated position and two standing up, with the P-Mate. Seated and standing flowmetry parameters were compared (by paired t-test). Twenty women completed the study. There was no difference in the maximum flow rate (Qmax), voided volume and post-void residual (PVR) in the standing versus the seated position. In terms of Qmax and PVR in healthy women, urinating standing up was as efficient as in the seated position. A majority of participants were satisfied with the device.

Women urinate in the standing position do not increase post‐void residual urine volumes

“…With auxiliary appliances, urination in the standing position is an alternative 5. In the current study, the data shows Q max does not increase with repeated episodes in the standing position, nor there was a decrease in the amount of residual urine in the bladder.…”

“…In this study, volunteers employed homemade auxiliary appliances, made of folded art paper. There are commercialized devices available that allow women to urinate in a standing position 5. The major concern for commercialized devices is limited availability.…”

Validation of a culturally compliant voiding platform for urodynamics in African vesicovaginal fistula patients

“…As a first step toward achieving these goals, we developed a prototype squatting platform for use during urodynamic testing. Few studies have been conducted on the effects of posture during voiding on uroflow parameters in women [14,23,36,37]. Of the two studies identified that compared squatting and sitting postures during voiding, both found differences in uroflow parameters [14,23].…”

Normal lower urinary tract assessment in women: I. Uroflowmetry and post-void residual, pad tests, and bladder diaries

“…Voiding position can affect uroflowmetry parameters. However, several studies have indicated that voiding position has no influence on them [30][31][32].…”
