Evaluate the effectiveness of three methods of measurement catheter fixation during urodynamic study: a single-center small sample size study

Abstract

Abstract Objectives This study in order to provide better evidence for the selection of fixation methods for measurement catheters during clinical UDS . Methods We selected patients who had undergone urodynamic examinations at the XXX between April and June 2023. These patients were chosen based on the inclusion and exclusion criteria established for the study. We observed the effectiveness of three different fixation methods: 1.Waterproof Tape Fixation(group1) 2. Patient-Manual Fixation(group2) 3. Silk Thread Fixation(group3). Results There were 28 patients enrolled in each group, and the mean ages were: 62.82 ± 15.59, 66.14 ± 8.63, 63 ± 16.78 years, respectively. MCC, BC, Qmax, Pdet.Qmax, BCI and BOO in 3 different catheter fixation methods had no statistical difference (P > 0.05). The total incidence of catheter displacement in group1, group2 and group3 was 35.71%, 0, 14.29%, respectively. There was a statistically significant difference between the Comfort-B scale of Group 1 and Group 2, Group 2 and Group 3 (p < 0.000). Regarding the visual analogue scores, there was a statistically significant difference between Group 1 and Group 2, Group 2 and Group 3 (p < 0.000). Conclusions We conducted a preliminary verification and found that three different methods of catheter fixation during UDS had no significant impact on the test results. However, it is important to note that patient-manual fixation, as well as the other two fixation methods, may result in decreased comfort and increased pain for patients during the UDS process.
