Abstract

Objective: The objective is to measure the change in overactive bladder (OAB) symptoms in patients undergoing flexible cystoscopy in the early postoperative period using a validated OAB-V8 tool.
Patients and methods: It was a prospective, cross-sectional, observational study conducted by a section of Urology at the Aga Khan University Hospital, Karachi. The total duration of the study was 12 months (July 2022 to June 2023). All adult patients who underwent flexible cystoscopy under local anesthesia for diagnostic and surveillance purposes were included in the study. OAB symptoms were evaluated using the validated eight-item OAB-V8 tool just before the cystoscopy and on postoperative days 1 and 4. Patients were categorized as either OAB-negative (<8) or OAB-positive (≥8) based on their sum scores. Mean sum scores of different variables and OAB subdomains were assessed.
Results: Sixty-three patients were included in the final analysis with a predominantly male population. The mean pre-cystoscopy (screen) score was 7.46 + 5.58, which increased to 9.89 + 6.82 on day 1 (p<0.01) before decreasing back to 7.68 + 5.7 on day 4 (p=0.08). Twenty-one patients (33.3%) were labeled OAB positive on day 0. Following cystoscopy, this number increased to 32 patients (50.8%) as 11 patients (26.2 %) developed de-novo OAB symptoms. The sub-group analysis showed an insignificant impact of age (p=0.5), gender (p=0.51), indication (p=0.22), and use of alpha-blocker (p= 0.30) on change in OAB score.
Conclusion: OAB symptoms are frequently encountered in patients undergoing awake (flexible) cystoscopy. This procedure can also trigger de novo OAB symptoms, albeit transiently, which typically resolve over time. This information could help in patient counseling, management, and the need for intervention in the future.
