Hypothesis / aims of study
Behavioral management including bladder training is the first choice of treatment for patients with overactive bladder syndrome (OABS) (1). However, there is still not enough knowledge about the proper content and best application methods of this treatment regimen. In order to explore this, we analyzed our patients’ records that were treated with bladder training (BT) in our Pelvic Floor Dysfunctions Rehabilitation Unit.
Study design, materials and methods
Data of female OABS patients’ allocated to bladder training between January, 2020-April 2021 were extracted from our rehabilitation unit database. In a routine scheme, a trained nurse supervised BT for 8 weeks. Some patients with insufficient response to treatment or who are willing to continue were continued to the same program as much as possible, until the desired 3-4 hours of micturition period is obtained. All patients were informed about OABS and were encouraged for life-style modifications. Patients were asked to void at pre-set intervals where duration of the interval was decided by the patient and the nurse as a shared decision. Then, the patients had weekly follow-up visits via phone calls led by the nurse to understand patient status during the week and to set a new voiding interval for the next week. Pre-set voiding interval was established as the longest possible duration for a patient without any urinary incontinence. All patients signed informed consents. Patients were asked to log a simple bladder diary for their urgency and incontinence episodes during this period. All patients’ age, duration of OABS symptoms, pre-treatment and post-treatment 3 day-bladder diary, Overactive Bladder-V8 Questionnaire (OAB-V8), International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), patient reported symptom severity of the last 3 days by visual analog scale (VAS-symptom severity: 0-10) and 24 hours pad test parameters were extracted from their medical records. During the SARS-CoV2-19 pandemic, we preferred phone calls instead of face-to-face visits for patient safety, so after the hospital initiation visit; consecutive visits were actualized via phone calls.
Interpretation of results
Our patients’ duration of voiding intervals almost doubled with 8 weeks of bladder training treatment (p<0.001; Table-1). Although this increase in voiding interval didn’t reflect on the voiding frequency at the same amount, bladder training was effective in reducing urgency, urinary incontinence and pad test results.
The percentage of patients achieving ≥3 hours of voiding interval at 8 weeks was relatively low (26%). This might be due to the fact that severe OABS patients were involved in bladder training treatment or due to the relatively short duration of treatment. Weekly intense follow-up for bladder training might have positively affected the outcome and patients’ adherence to treatments. However, given the non-randomized and uncontrolled nature of our study, it is impossible to make a conclusion.
