ABSTRACT
Background: Overactive bladder is a clinical entity with a high prevalence that causes a great impact on the quality of life. Botulinum toxin has been shown to be effective in the treatment of this pathology, improving the symptoms and life of patients.Objective: The objective of this study is to evaluate the outcome, complications and impact of quality of life in patients with refractory overactive bladder after intravesical application of botulinum toxin.
Material and methods: It is carried out a prospective study of 85 patients with overactive bladder refractory to medical treatment and in whom intravesical injection of 100 UI of botulinum toxin was performed between 2016 and 2018. The characteristics of the patients, complications and the results of the questionnaires OAB-V8 (Overactive Bladder), ICIQ-SF (Urinary incontinence) and the SF-36 Health Questionnaire (Quality of life) before and after the application of the treatment have been reviewed. For the comparison of results, the Student’s t-test for paired data or Wilcoxon was used. A value of p < 0.05 was considered statistically significant.
Results: The most frequent complication was to present a high postvoid residual in 16.47% of the patients, followed by a positive urine culture in 9.41%. The changes in the parameters of the questionnaires after the month of application, compared to the pre-application assessment, were statistically significant for OAB-V8 scale and for ICIQ-SF questionnaire, but not for the Health Questionnaire SF-36. The most affected dimensions were the physical and social function and the physical and emotional role.
Conclusions: The intravesical application of botulinum toxin is a safe and well tolerated procedure, with minimal complications, which reduces episodes of urgency and urinary incontinence, improving the quality of life of patients.
