UPP traces were classified as smooth or pulsatile and the EMG was classified as normal or abnormal. Statistical analysis was by Chi squared test for pulsatile UPP trace as a predictor of abnormal EMG. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of a pulsatile UPP trace for predicting abnormal EMG were also determined. These patients were asked to complete a telephone interview assessing discomfort on catheterization, particularly on catheter removal (\u201ccatching\u201d).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 107 women of mean age 35.8 years underwent both sphincter EMG and UPP between 2011 and 2015.
