Summary
Air insufflation during flexible cystoscopy significantly improves patient comfort compared to water irrigation. This method offers a better view and is equally safe and effective, making it ideal for routine use.
Area of Science:
- Urology
- Minimally Invasive Procedures
Background:
- Flexible cystoscopy is a common diagnostic procedure.
- Patient tolerance and procedural outcomes are key considerations.
Purpose of the Study:
- To compare patient tolerance and outcomes of air insufflation versus water irrigation during diagnostic flexible cystoscopy.
Main Methods:
- 200 patients undergoing routine flexible cystoscopy were randomized to air insufflation or water irrigation.
- Patient tolerance and post-operative symptoms were assessed via questionnaires.
Main Results:
- Air insufflation provided a superior cystoscopic view.
- Significantly higher comfort levels were reported with air insufflation (72% comfortable vs. 44% with water, P < 0.001).
- No differences in post-operative symptoms or diagnostic yield were observed; no complications occurred.
Conclusions:
- Air insufflation cystoscopy is a safe and effective alternative to water irrigation.
- Improved patient tolerance, ease of administration, and low cost support routine use of air insufflation.
