Long-term outcome of the use of intravesical botulinum toxin for the treatment of overactive bladder (OAB)
Amar Mohee, Ayisha Khan, Neil Harris, Ian Eardley
OBJECTIVES
• To assess the long-term compliance with repeated injections of intravesical botulinum toxin (BT) in a ‘real-life’ mixed population of patients with idiopathic detrusor overactivity and neurogenic detrusor overactivity.
• To identify the reasons why patients discontinued BT therapy and to explore the outcomes of those patients who did discontinue treatment.
PATIENTS AND METHODS
• Retrospective evaluation of the case notes of a series of patients who had received intravesical BT treatment at a large UK teaching hospital.
• No antibiotic prophylaxis was given for the procedure.
RESULTS
•Over a period of 7 years, 268 patients were initiated on intravesical BT treatment for overactive bladder (OAB) at our institution, with 137 followed up for ≥36 months, with 80 patients having ≥60 months follow-up after their first injection.
• Almost two-thirds of patients (61.3%) had discontinued intravesical BT therapy at 36 months, with a 63.8% discontinuation rate at 60 months.
• The main reasons for discontinuation were tolerability issues, mainly urinary tract infections and the need for clean intermittent self-catheterisation. Primary and secondary losses of efficacy were of secondary importance.
• Most of the patients that discontinued have remained under urology care and now receive alternative methods of treatment.
CONCLUSIONS
• Intravesical BT therapy is an effective short-term treatment for OAB.
• With time, two-thirds of patients discontinued treatment usually because of the tolerability issues associated with treatment.
