RESUMEN
ABSTRACT Aim: To evaluate the efficacy of the onabotulinum toxin type A in the treatment of HTLV-1 associated overactive bladder and its impact on quality of life (QoL). Methods: Case series with 10 patients with overactive bladder refractory to conservative treatment with anticholinergic or physical therapy. They received 200Ui of onabotulinumtoxin type A intravesically and were evaluated by overactive bladder symptoms score (OABSS) and King's Health Questionnaire. Results: The mean (SD) of the age was 52 + 14.5 years and 60% were female. All of them had confirmed detrusor overactivity on urodynamic study. Seven patients had HAM/TSP. The median and range of the OABSS was 13 (12-15) before therapy and decreased to 1.0 (0-12) on day 30 and to 03 (0-14) on day 90 (p < 0.0001). There was a significant improvement in 8 of the 9 domains of the King's Health Questionnaire after the intervention. Hematuria, urinary retention and urinary infection were the complications observed in 3 out of 10 patients. The mean time to request retreatment was 465 days. Conclusion: Onabotulinum toxin type A intravesically reduced the OABSS with last long effect and improved the quality of life of HTLV-1 infected patients with severe overactive bladder.
