The treatment of overactive bladder syndrome with onabotulinumtoxinA therapy

Introduction: Overactive bladder syndrome is an endemic phenomenon, which has a significant impact on the quality of life. In cases where conservative treatment fails, intradetrusor onabotulinumioxin A injection can be used as second-line therapy. Objective: To assess the safety and efficacy of onabotulinu.mtoxin A treatment in the management of non-neurogenic detrusor overactivity among our patients. Also, to examine the influence of perioperative factors on the effects of the efficacy. Method: We have retrospectively collected the perioperative data of 33 patients treated with intradetrusor BOTOX (R). The assessment of the efficacy and complications was done by the examination of patient files and questionnaires. The results obtained during the statistical analysis were considered significant for p<0.05. Results: We have not experienced notable complications after the procedures. Only 6 patients had residual urine (p = 0.024), none of them needed to be catheterized. We have observed significant decrease in the incidence of frequency, nocturia, urgency and incontinence, just as in the number of pads needed daily (p<0.01). Quality of life and general health were significantly improved (p<0.001). We have not found any significant connection between preoperative factors and efficacy (72.7%). Discussion: Our results considering the relief of symptoms are well in line with international data. The fact that our rate of complications is - in international comparison - outstanding can be explained by a more careful patient selection and thorough preoperative assessment. Conclusion: Onabotulinumtoxin A therapy is a safe and effective solution of therapy-refractory overactive bladder. We could not identify any perioperative factor to predict postoperative efficacy of therapy.
