To evaluate overactive bladder (OAB) symptoms in patients undergoing diagnostic cystoscopy. Overall changes in the entire study population were assessed, as well as broken down by various subgroups.
A prospective multi-center study among consecutive 450 adults undergoing diagnostic cystoscopy was conducted. OAB-symptoms were evaluated with the validated eight-item OAB Screening Awareness Tool (OAB-V8) immediately before and on days 1, 4, and 7 after cystoscopy. Patients were distinguished between being OAB-negative and OAB-positive (< 8 and ≥ 8 sum-score, respectively). Average sum-scores and subdomains were evaluated.
Before cystoscopy, 44.7% of patients were screened OAB-positive and 55.3% OAB-negative. Out of those being screened negative, development of de-novo OAB was noticed in 16.8%, declining to 8.1% on day 7 (p < 0.001). In patients being OAB-positive before cystoscopy, a decline of OAB-positivity was noted during follow-up (p < 0.001). No statistically significant differences were noted when broken down by gender (p = 0.92), age (p = 0.82) and type cystoscope (rigid vs. flexible, p = 0.38). Average sum-scores declined from 8.68 before cystoscopy to 6.9 during follow-up. Flexible cystoscopy was superior over rigid in four subdomains: uncomfortable urge to urinate (p = 0.04), sudden urge to urinate with little or no warning (p = 0.02), uncontrollable urge to urinate (p = 0.03), and urine loss associated with a strong desire to void (p = 0.009).
OAB-symptoms are common in patients undergoing cystoscopy. Cystoscopy itself can cause de-novo OAB-symptoms. Controversially, a decline of OAB-symptoms was noted after cystoscopy when patients were screened OAB-positive before cystoscopy. Flexible scopes were superior in some subdomains.
