pH testing in catheter maintenance: the clinical debate.
The pH of urine is widely recognized as being a major contributory factor in urinary catheter encrustation. What is less widely appreciated is the range of factors that affect the pH of urine, and which therefore affect the reliability and validity of urine pH testing. This article examines the validity of various urinary pH testing methods and discusses the theoretical and practical implications of the uncertainty surrounding their practical value.
