Effect of bacteria in feces on pH of bladder control pad top sheet

Abstract

Objective:To clarify the relationship in pH between bladder control pad top sheet and skin and effect of bacteria on the pH.
Methods:We measured the pH of top sheet and skin near the external urethral orifice and examined bacteriological property of top sheet at four time points； before urination,soon later,120-160-minute later,and 240-300-minute later.
Results:Both pH of top sheet and skin increased over time. Cases with high levels of top sheet pH showed strong activity of urease and exhibited Genus Proteus colonization.
Discussion:These results suggested the relationship between top sheet pH and skin pH. Increase of top sheet pH could be related to urease derived from bacteria in feces.
