Botulinum toxin type A may improve bladder function in a rat chemical cystitis model 总被引:3,自引:0,他引:3
The purpose of this study was to investigate the effect of botulinum toxin type A on bladder function and histology in a rat chemical cystitis model. The study included 41 female Sprague-Dawley rats with chemical cystitis induced by intravesical instillation of hydrochloric acid. The acid instillation was repeated monthly to maintain chronic inflammation. The treatment group (n=21) received 2-3 units of botulinum toxin type A injected into the bladder detrusor at the 3, 6, 9 and 12 o'clock positions, and the control group (n=20) underwent saline injection into the bladder detrusor at the same positions. Urodynamic studies were performed in all rats before the treatment and at death. The rats were killed at 1 week, 2 weeks, 1 month and 2 months after treatment. The bladders were removed and examined histologically for mast cells and inflammatory changes. The cystometric findings showed that, at the beginning and end of the experiment, the increases in the maximum bladder capacity and compliance were significantly higher in the treatment group than in the control group (P=0.000 and P=0.025, respectively). The histological studies revealed similar mast cell counts and leukocyte infiltration for the treatment and control groups. In conclusion, in this rat chemical cystitis model, botulinum toxin type A injected into the bladder detrusor led to a functional improvement. Thus, botulinum toxin type A injection may be an alternative, minimally invasive choice to other surgical treatment options in the treatment of a chronic inflammatory condition to improve deteriorated bladder function. 相似文献

Many papers report the clinical success of botulinum toxin A as a method of management of various bladder dysfunctions. The rationale was that botulinum toxin A was able to block the presynaptic release of acetylcholine from the parasympathetic efferent nerve. The efficacy might result not only from an inhibitory effect on detrusor muscle, but also some effects might be mediated by altering the afferent nerve input. This systematic literature review discusses the efficacy and safety of botulinum toxin A therapy for idiopathic detrusor overactivity, neurogenic detrusor overactivity, interstitial cystitis/painful bladder syndrome and benign prostatic hyperplasia. The information was gathered from a PubMed literature research for abstracts from recent urological meetings. Injection of botulinum toxin A appears to have a positive therapeutic effect in multiple urological conditions, such as refractory idiopathic detrusor overactivity, neurogenic detrusor overactivity, interstitial cystitis/painful bladder syndrome and benign prostatic hyperplasia. Because the United States Food and Drug Administration has approved botulinum toxin A (Botox) for injection for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity (e.g. spinal cord injury, multiple sclerosis) in adults who have an inadequate response to or are intolerant of an ant cholinergic medication, the use of botulinum toxin A will spread and be a more familiar therapy in the urological arena. However, further robust evidence should be awaited. We will discuss the current use of this agent within the urological field. 相似文献

PURPOSE: Treatment of interstitial cystitis is usually not successful in eradicating bladder pain and increased bladder capacity. This study was designed to evaluate the clinical effectiveness of suburothelial injection of botulinum A toxin in patients with chronic interstitial cystitis. METHODS: Eight women and 2 men with chronic interstitial cystitis who had failed conventional treatments were enrolled in this study. In 5 patients, 100 units of botulinum A toxin was injected suburothelially into 20 sites, and an additional 100 units was injected into the trigone in the other 5 patients. Therapeutic outcome including functional bladder capacity, number of daily urinations, bladder pain, and urodynamic changes were compared between baseline and 3 months after treatment. RESULTS: In 2 patients bladder pain and urinary frequency were improved 3 months after treatment. Mild difficulty in urination was reported by 7 patients. Functional bladder capacity recorded in a voiding diary was significantly increased (155+/-26.3 vs. 77+/-27.1 ml, p<0.001), and the frequency of daily urinations (18+/-7.7 vs. 24.2+/-10.3, p=0.025) and the pain score (2.4+/-1.6 vs. 3.2+/-1.1, p=0.003) were mildly but significantly reduced after treatment. Only the cystometric capacity improved significantly (287+/-115 vs. 210+/-63.8 ml, p=0.05) in urodynamic results. Trigonal injection had no therapeutic effect on symptom or urodynamic improvement. No adverse effect was reported. CONCLUSIONS: The clinical result of suburothelial botulinum A toxin injection was disappointing. None of the patients was symptom free and only a limited improvement in bladder capacity and pain score was achieved in 2 patients. 相似文献

Botulinum toxin type a injections into the trigone to treat idiopathic overactive bladder do not induce vesicoureteral reflux 总被引:2,自引:0,他引:2
Karsenty G Elzayat E Delapparent T St-Denis B Lemieux MC Corcos J 《The Journal of urology》2007,177(3):1011-1014
PURPOSE: We assessed the generation of vesicoureteral reflux before and after injection of botulinum toxin A into the trigone of patients with nonneurogenic overactive bladder, and evaluated its short-term efficacy. MATERIALS AND METHODS: Adults with nonneurogenic overactive bladder resistant to behavioral treatments, pelvic floor exercises, medication and neuromodulation were included in the study. The initial evaluation (history, physical examination, 3-day urinary diary, V8 score, flowmetry and post-void residual) was repeated 6 weeks after botulinum toxin A injection. Videourodynamic study was performed 1 hour before injection and 6 weeks later. Botulinum toxin A (200 units) was injected into the detrusor in 10 sites over the bladder base including the trigone. The primary outcome was the presence or absence of vesicoureteral reflux before and 6 weeks after botulinum toxin A injection. The secondary outcomes were clinical and urodynamic parameter changes. Values were compared using the Wilcoxon test. RESULTS: A total of 12 women were enrolled in the study (median age 76 years). The duration of symptoms was 7.5 years. One patient was excluded from analysis because of a urinary tract infection. There were 10 women with no vesicoureteral reflux at baseline and 1 had bilateral vesicoureteral reflux (grade 2 right, grade 1 left). At 6 weeks there was no induced vesicoureteral reflux and the patient with vesicoureteral reflux at baseline showed no change in vesicoureteral reflux grade. No local or systemic side effects related to botulinum toxin A were reported. In terms of efficacy, at direct questioning 6 weeks after treatment 4 of 11 patients reported an improvement that made them ask for another injection. CONCLUSIONS: Botulinum toxin A injection into the trigone does not induce de novo vesicoureteral reflux in patients with nonneurogenic overactive bladder. The therapeutic value of this approach remains to be confirmed and compared to other injection designs. 相似文献

We report one institution's six-year experience using botulinum toxin A (BONT-A) in the bladder and urethra in 110 patients for a variety of lower urinary tract dysfunction. 110 patients (age 19-82) were injected with BONT-A into the bladder (n=42) or urethra (n=68), 35 M, 75 F. Voiding dysfunction included: neurogenic detrusor overactivity and/or detrusor sphincter dyssynergia, overactive bladder (OAB), benign prostatic hyperplasia (BPH), bladder neck obstruction (BNO) and interstitial cystitis (IC). Currently, 27 patients have undergone further injections (up to 6) at intervals > 6 months. All the patients with bladder BONT-A injection had preoperative evidence of involuntary detrusor contractions during urodynamic testing. Analysis of the 110 patients indicates that 67.3% reported a decrease or absence of incontinence. Diaries indicate a decrease in both day and night voiding symptoms. Efficacy occurred within 7 days and lasted for at least 6 months. Condition specific QOL symptom scores also demonstrated improvement. There have been no long-term complications. Two MS women with mild baseline stress urinary incontinence reported increased leakage with stress after BONT-A external sphincter injection. One MS woman who had a bladder injection had an increased residual urine from 78 to 155 ml. She did not have to perform intermittent catheterization. BONT-A injection is a safe and promising treatment modality for a variety of lower urinary tract dysfunctions for both skeletal and smooth muscle dysfunction. In our series, BONT-A is equally effective in women as it is in men. Bladder injections with BONT-A are effective for not only neurogenic detrusor overactivity but also overactive bladder. BONT-A can even be considered for IC. 相似文献

Botulinum toxin A is available under three different protein complexes that are not interchangeable until appropriate comparative studies are undertaken. The best studied for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity and overactive bladder/idiopathic detrusor overactivity is onabotulinum toxin A. This brand is only approved for the treatment of urinary incontinence as a result of neurogenic detrusor overactivity at a dose of 200 U and idiopathic detrusor overactivity at a dose of 100 U. In patients with detrusor overactivity as a result of spinal cord injury or multiple sclerosis, 200 U of onabotulinum toxin A should be injected in 30 different sites above the trigone. It was shown to be highly effective in curing or decreasing urinary symptoms of incontinence, increasing quality of life, increasing bladder capacity and decreasing maximal detrusor pressure. This effect was independent of the concomitant use of oral anticholinergic drugs. Adverse events were mild, mainly urinary tract infections and high postvoid residual requiring clean intermittent catheterization. In patients with overactive bladder/idiopathic detrusor overactivity, 100 U of onabotulinum toxin A should be injected in 20 sites above the trigone. It markedly decreases urinary incontinence and improves quality of life. Frequency and urgency episodes are also decreased. Adverse events are mild, mainly urinary tract infections and urinary retention. The latter occurred in just 5% of the patients. Candidates for onabotulinum toxin A treatment should be warned that the effect of the toxin is transient and that repeated injections will be required to maintain the effect in the long term. There is no evidence that repeated injections will have a decreased efficacy. 相似文献

PURPOSE OF REVIEW: To review the most recent experience concerning the application of botulinum toxin in the human lower urinary tract. RECENT FINDINGS: Botulinum toxin was initially applied in the bladder of patients with spinal neurogenic detrusor overactivity and urinary incontinence, or in the urethra in cases of detrusor external sphincter dyssynergia. A large multicentric European study fully confirmed the initial expectancy in the former condition. In addition, the application of botulinum toxin was extended to the treatment of other urological disorders including non-neurogenic detrusor overactivity, non-relaxing urethral sphincter and detrusor underactivity. Interesting reports on the injection of botulinum toxin into the prostate of patients with benign prostatic hyperplasia are also reviewed. SUMMARY: Bladder injection of botulinum toxin is not yet an approved treatment for lower urinary tract dysfunction. Nevertheless, available data suggest that in the near future the toxin will become a standard therapeutic option in incontinent patients with neurogenic and non-neurogenic forms of overactive bladder, who do not respond to or do not tolerate anticholinergic medication. In addition, it might be expected that urethral botulinum toxin injections improve bladder emptying in patients with dysfunctional voiding problems besides detrusor external sphincter dyssynergia. 相似文献

The diagnostic criteria for interstitial cystitis considered as a subgroup of painful bladder disease (that is sensory bladder disease and chronic abacterial cystitis) are not well established. Some urologists rely on symptoms, while others rely on cystoscopic appearance or pathological findings. Among 115 patients with painful bladder disease we compared symptoms, and cystoscopic and urodynamic findings in those with and without detrusor mastocytosis (28 or more mast cells per mm.2) and attempted to elucidate possible differences between the groups. We chose the pathological anatomical criterion of detrusor mastocytosis to be diagnostic for interstitial cystitis. A total of 43 patients had detrusor mastocytosis and other pathological anatomical signs of interstitial cystitis, and 72 had no mastocytosis but the pathological diagnoses of chronic unspecific cystitis, fibrosis of the bladder, detrusor myopathy, intestinal metaplasia and normal findings. When the 2 groups of patients were compared we found no differences in regard to symptoms (pain, dysuria, frequency, nocturia and urgency), frequency of allergy and hysterectomy, duration of symptoms, petechial bleeding during cystoscopy with bladder distension and cystometric findings. The patients with mastocytosis differed from those without mastocytosis in that they were older, and had a higher frequency of hematuria, a higher frequency of a red, scarred and richly vascularized bladder at cystoscopy before distension, and a smaller cystoscopic bladder capacity. We conclude that by dividing patients with painful bladder into 2 groups according to the mast cell counts in the detrusor, certain differences in the clinical findings in the groups can be ruled out. However, in individual patients one cannot note with certainty to which pathological anatomical group the patient belongs, since great overlapping between the groups exists. Whether only patients with detrusor mastocytosis have interstitial cystitis depends on definitions and still remains an open question. 相似文献
