A Comparison of Intraurethral Lidocaine Lubricant and Plain Lubricant in Reducing Urethral Discomfort during Rigid Cystoscopy
Keywords:
Lidocaine Lubricant, Plain Lubricant, Rigid CystoscopyAbstract
Introduction: There is no clear evidence that intraurethral lidocaine jelly decreases pain and/or makes rigid cystoscopy more tolerable for patients. Since lidocaine jelly is significantly more expensive than plain lubricant, this research was conducted to assess the true benefit of this agent.
Materials and methods: This prospectively randomized study was conducted to compare the anesthetic effects of intraurethral lidocaine lubricant against plain lubricant in 156 patients undergoing rigid cystoscopy. 156 Patients were divided into two groups. Patients in group 1 were treated with 10 ml of 2% lidocaine lubricant, and those in group 2 were treated with 10 ml of plain lubricant. Cystoscopy was performed by only one urologist using a 17Fr rigid instrument. The groups were compared according to postprocedural data including pain score, indications, cystoscopy history, anxiety level, procedure time, and age of patients.
Result: A total of 156 patients were enrolled. The male and female allocation ratio was 2:1. The mean of pain scores in lidocaine lubricant and plain lubricant were 3.23 (SD=1.58) and 3.22 (SD=1.66), respectively. The pain scores were statistically equivalent with a mean difference of -0.01 (95%CI: -0.52, 0.50). Ages, indication, cystoscopy history, duration of procedure, and anxiety prior to a cystoscopy were found not to significantly affect the reported pain.
Conclusions: Lidocaine lubricant offered no advantage over plain lubricant in regard to pain control during rigid cystoscopy.
