Weekly measurement of urinary pH has become a standard part of long-term catheter management in many parts of the UK. The common problem of catheter encrustation is caused by urease-producing bacteria which also tend to produce alkaline urine. To determine if urinary pH changes in individual catheter users provided enough information for pH monitoring to aid in catheter management, an analysis of the literature was combined with a study of the urinary pH and catheter blockage patterns in 20 catheter users colonized with urease-producing bacteria. It was found that weekly pH measurement does not aid in the diagnosis or management of catheter encrustation. As such, this practice cannot be recommended.
在英国许多地区，每周测量尿液pH值已成为长期导管管理的标准组成部分。导管结壳这一常见问题是由产脲酶细菌引起的，这些细菌往往还会产生碱性尿液。为了确定个体导管使用者尿液pH值的变化是否能为pH监测提供足够信息以辅助导管管理，我们将文献分析与对20名定植有产脲酶细菌的导管使用者的尿液pH值及导管堵塞模式的研究相结合。结果发现，每周测量pH值无助于导管结壳的诊断或管理。因此，不推荐这种做法。
