Abstract
OBJECTIVE
To determine if a modified cystoscopy technique utilizing the peak-end rule cognitive bias decreases pain and anxiety during flexible cystoscopy in patients who undergo cystoscopy.
METHODS
A total of 85 participants undergoing their first diagnostic cystoscopy were enrolled in a blinded single-center, prospective, randomized controlled trial. Patients with lower urinary tract abnormalities, prior radiation and chronic pelvic pain were excluded. Participants were randomized to a standard cystoscopy (arm A) or a modified cystoscopy (arm B) where a two-minute period at the end of the procedure was completed during which the cystoscope was left in the bladder without being manipulated. Following the cystoscopy, participants completed a standard pain and anxiety questionnaire. Differences in mean pain and anxiety score between arms were evaluated using a Mann-Whitney test with a two-sided alpha of 0.05.
RESULTS
Eighty-five patients were randomized and underwent flexible cystoscopy. Three participants were ineligible, one required secondary procedures, and two did not complete the questionnaires. Among the 82 eligible patients, 45 were randomized to standard cystoscopy (arm A) and 37 to the modified cystoscopy (arm B) with mean pain scores of 23.20 and 11.97, respectively (P = .039). Mean anxiety scores were 2.09 and 0.88 for arm A and B, respectively (P = .013).
CONCLUSION
This study demonstrated a clinically meaningful decrease in pain and anxiety for patients undergoing flexible cystoscopy when employing the modified cystoscopy technique versus the standard practice. This free and straightforward method to improve patient comfort and decrease stress during first time flexible cystoscopy should be considered by clinicians.
