Safety and Efficacy of botulinumA Toxin (BotoxA) for Treatment of Neurogenic Bladder of Parkinson's Disease
The basic nerve deficit of Parkinson's disease (PD) leads to lower urinary tract symptoms of frequency, urgency and urge urinary incontinence. Lower urinary tract symptoms tend to occur at more advanced stages of PD. In the over-65 year old age group, where 1% of men suffer from this disease, they are also prone to development of benign prostatic hyperplasia (BPH) and consequent associated lower urinary tract dysfunction. Similarly the over 65-year age group develop spontaneous overactive bladder up to a prevalence of 30% of both men and women. The urologic disorder is exceedingly devastating in reducing the quality of life in these individuals due to the lower urinary tract symptoms and ultimate urinary incontinence in a high proportion of patients.
While attempts at pharmacologic treatment are partially satisfactory many patients are intolerant of oral drugs.
Botulinum-A neurotoxin (BTX-A) has been shown in pilot trials to be quite effective in reducing overactive bladder symptoms and is specifically beneficial for a wide-variety of neurogenic bladder causes of over activity . The treatment procedure of injecting the detrusor muscle of the bladder with BTX-A is quite simple, does not impose significant risks to the patient, and can be performed as an office urologic procedure.
This pilot clinical trial intends to demonstrate the safety and efficacy of low-dose Botox-A injections into the bladder to improve urinary symptoms in 20 patients.
