Cooled (4ºC) Lidocaine during office cystoscopy improves male patient satisfaction and comfort: A prospective, randomized, double-blind, controlled study
Introduction:
In these times when there are so many different ways to ameliorate the pain associated with office cystoscopy, we devised this study to prospectively evaluate the efficacy of cooling intraurethral Lidocaine jelly to 4ºC in reducing male patient discomfort.
Materials and Methods:
A total of 600 male patients scheduled for office diagnostic cystoscopy were enrolled and randomized into three groups for a prospective controlled double-blind study. Each group received one of the three methods of intraurethral lubrication: plain room temperature lubricant (control) (CON), room temperature Lidocaine (LI), or Lidocaine at 4ºC (LI4ºC). Pain perceived was recorded on a Likert visual analog scale (VAS) of 1-10 where 0 = no pain and 10 = excruciating pain. Kruskal-Wallis test assessed the efficacy of cooling Lidocaine compared to room temperature Lidocaine and a control. Subjective pain reporting was corroborated with instantaneous objective pulse rate recording eliminating perception bias.
Results:
There was no significant difference in cystoscopy duration between all groups. Mean pain scores (M±SD) were 4.05 ± 0.91, 2.74 ± 1.01, and 1.8 ± 0.84, respectively, for groups CON, LI, and LI4ºC (p = .02). There was 32.34% reduction in the mean pain score of LI and a further reduction of 34.3% was achieved in LI4ºC when compared to CON. Body mass index and the weight of prostate had a significant positive correlation with pain score, whereas no such correlation was found with age.
Conclusion:
Cooling Lidocaine to 4ºC for office cystoscopies provides a method of giving additional analgesic benefits and increases male patient compliance.
