Factors predicting the treatment success of bladder training for urgency urinary incontinence.

Objective: To evaluate the efficacy of bladder training (BT) for urgency urinary incontinence (UUI) and to determine women characteristics that are predictors for success.

Methods: Clinical data of 110 women with UUI who had received BT over 8 weeks were analyzed retrospectively. Patients were evaluated in terms of incontinence severity (24-h pad test), 3-day voiding diary (frequency of voiding, nocturia, incontinence episodes, and the number of pads), symptom severity (OAB-V8), incontinence-related QoL (IIQ-7) and treatment success. Treatment success was evaluated at a ≥50% reduction in incontinence episodes at the end of the treatment.

Results: A statistically significant improvement was found in all parameters (incontinence severity, frequency of voiding, nocturia, incontinence episodes and the number of pads, symptom severity, and incontinence-related QoL) at the end of the treatment compared to the baseline values in women with UUI who had received BT (p < 0.001). The treatment success rate was 35.5%. In the multivariate analysis (OR, 95% CI), the treatment was found to be more successful in women with higher education levels (p = 0.012, p = 0.029) and of younger ages (p = 0.004).

Conclusion: It can be concluded that the BT given to women with UUI is effective in reducing incontinence severity, frequency, nocturia, incontinence episodes, number of pads, symptom severity, and improving QoL. Young age and high education levels are the predictive factors in the treatment success of BT in women with UUI. For this reason, these predictive factors should be considered in determining the treatment strategy for women with UUI.
