Abstract:

Objective

To evaluate the pain during and after urodynamic examination of women using 2% lidocaine gel and lubricant gel.

Methods

A randomized，controlled，double-blind study was conducted. During the examination，female patients who received urodynamic examination were randomly divided into 2% lidocaine gel group and lubricant gel group. Neither the patient nor the examining physician knows the type of gel. Patients self-reported their pain levels before the start of the examination，after the cotton swab examination，and 30 minutes after the placement of the urinary dynamic catheter. The pain was evaluated using the Wong Baker Pain Scale，with a score range of 0-10 points. After the examination is completed，the patient will use the Likert scale to assess the extent of pain compared to expectations. The examining physician scores the patient's impression of pain during the examination process after the examination is completed.

Results

A total of 75 patients were included in the study，including 38 patients in the 2% lidocaine gel group and 37 patients in the lubricant gel group. The pain scores of patients in the 2% lidocaine gel group were lower than those in the lubricant gel group after swab examination and placement of urodynamic catheter （P＜0.001）. There was no significant difference in the average pain scores between the two groups 30 minutes after the examination was completed （P＞0.05）.Both groups of patients believed that the pain during the examination was milder than expected. The examination physician's perception of pain during the examination was that the 2% lidocaine gel group was lower than the lubricant group （P＜0.001）.

Conclusion

2% lidocaine gel can alleviate the pain of catheter insertion and swab examination in urodynamic examination.
