PURPOSE: Of the various treatments proposed for urge incontinence, frequency and urgency electrostimulation has been widely tested. Different techniques have been used with the necessity of surgical implantation (S3 neuromodulation or sacral root stimulation) or without requiring surgery (perineal transcutaneous electrostimulation). Recently peripheral electrical stimulation of the posterior tibial nerve was proposed for irritative symptoms in first intention or for intractable incontinence. Clinical studies have demonstrated good results and urodynamic parameters were improved after chronic treatment. However, to our knowledge no data concerning acute stimulation and immediate cystometry modifications have been reported. We verified urodynamic changes during acute posterior tibial nerve stimulation. MATERIALS AND METHODS: A total of 44 consecutive patients with urge incontinence, frequency and urgency secondary to overactive bladder were studied. There were 29 women and 15 men with a mean age +/-SD of 53.3 +/- 18.2 years. Of the patients 37 had detrusor hyperreflexia due to multiple sclerosis (13), spinal cord injury (15) or Parkinson's disease (9), and 7 had idiopathic detrusor instability. Routine cystometry at 50 ml. per minute was done to select the patients with involuntary detrusor contractions appearing before 400 ml. maximum filling volume. Repeat cystometry was performed immediately after the first study during left posterior tibial nerve stimulation using a surface self-adhesive electrode on the ankle skin behind the internal malleolus with shocks in continuous mode at 10 Hz. frequency and 200 milliseconds wide. Volume comparison was done at the first involuntary detrusor contraction and at maximum cystometric capacity. The test was considered positive if volume at the first involuntary detrusor contraction and/or at maximum cystometric capacity increased 100 ml. or 50% during stimulation in compared with standard cystometry volumes. RESULTS: Mean first involuntary detrusor contraction volume on standard cystometry was 162.9 +/- 96.4 ml. and it was 232.1 +/- 115.3 ml. during posterior tibial nerve stimulation. Mean maximum cystometric capacity on standard cystometry was 221 +/- 129.5 ml. and it was 277.4 +/- 117.9 ml. during stimulation. Posterior tibial nerve stimulation was associated with significant improvement in first involuntary detrusor contraction volume (p <0.0001) and significant improvement in maximum cystometric capacity (p <0.0001). The test was considered positive in 22 of the 44 patients. CONCLUSIONS: These results suggest an objective acute effect of posterior tibial nerve stimulation on urodynamic parameters. Improved bladder overactivity is an encouraging argument to propose posterior tibial nerve stimulation as a noninvasive treatment modality in clinical practice. 相似文献

Pharmacotherapy is the first-line treatment for overactive bladder, but many patients discontinue drug therapy because of intolerable side effects, expense, or lack of longterm adherence. Alternative treatments are needed for patients who are unable to tolerate pharmacotherapy or who do not derive the desired benefits. Sacral nerve stimulation therapy has evolved into one of the most widely accepted treatment modalities in the arena of neurourology. Sacral nerve stimulation activates or "resets" the somatic afferent inputs that play a pivotal role in the modulation of sensory processing for micturition reflex pathways in the spinal cord. This minimally invasive technology offers a safe, reliable, and durable treatment for lower urinary tract dysfunction. 相似文献

AIM: The aim of this study was to evaluate urodynamic changes after percutaneous tibial nerve stimulation (PTNS) for the treatment of complaints related to overactive bladder syndrome and to search for urodynamic-based predictive factors. METHODS: Ninety consecutive patients with symptoms related to overactive bladder syndrome were enrolled in this study. Patients underwent 12 PTNS sessions. For evaluating objective success, the primary outcome measure was a reduction in number of urinary leakage episodes of 50% or more per 24 hours. Patients' request for continuation of therapy was considered subjective success. This study focussed on urodynamic features at baseline and on changes found after 12 PTNS treatments. RESULTS: The objective success rate was 56% (leakages/24 hours). Subjective success rate was 64%. Frequency/volume chart data and quality of life scores improved significantly (P < 0.01). Pre- and posturodynamic data were available from 46 participants. Detrusor instabilities (DI) could be abolished in a few cases only. Increments in cystometric bladder capacity and in volume at DI were significant (P = 0.043 and 0.012, respectively). Subjects without detrusor instabilities at baseline were 1.7 times more prone to respond to PTNS (odds ratio, 1.75; 95% confidence interval [CI], 0.67-4.6). The more the bladder overactivity was pronounced, the less these patients were found to respond to PTNS, the area under the receiver operating curve was 0.644 (95% CI, 0.48-0.804). CONCLUSION: PTNS could not abolish DI. PTNS increased cystometric capacity and delayed the onset of DI. Cystometry seemed useful to select good candidates: patients without DI or with late DI onset proved to be the best candidates for PTNS. 相似文献

OBJECTIVE: In sacral as well as tibial nerve stimulation test stimulation is the main prognostic factor for success. In our study we tried to identify prognostic patient characteristics to improve patient selection for neuromodulation therapy. METHODS: PTNS was applied to 132 patients in 8 study centers (51 men, 81 women, mean age of 53 years (range: 21-82)). 83 patients were treated for overactive bladder, 16 for non-obstructive urinary retention and 33 for chronic pelvic pain. All patients had to fill out micturition or pain diaries, as well as quality of life questionnaires before and after treatment. Patient characteristics were evaluated for their prognostic value for successful outcome of neuromodulation therapy with use of logistic regression. RESULTS: Objective success was seen in 32.6% of patients, subjective success in 51.5%. Most evaluated clinical parameters proved not to be of prognostic value. A history of sexual and/or physical abuse was found in 12 of 103 interviewed patients, but did not alter PTNS treatment outcome. However, a low total score at baseline in the SF-36 questionnaire proved to be predictive for not obtaining objective (OR 0.444 [95% CI: 0.198-0.996], p = 0.04) or subjective success (OR 0.424 [CI: 0.203-0.887], p = 0.02). Especially patients with a low SF-36 Mental Component Summary were prone to fail neuromodulation therapy: OR 0.123 (95% CI: 0.273-0.552), p = 0.006 for objective success. These patients also scored worse on disease-specific quality of life questionnaires, although they had no different disease severity compared to patients with good mental health. CONCLUSION: Bad mental health as measured with the SF-36 Mental Component Summary does not depend on symptom severity and is a negative predictive factor for success of percutaneous tibial nerve stimulation. It therefore might be used as a tool for better patient selection in neuromodulation therapy. 相似文献

Introduction and hypothesis
Posterior tibial nerve stimulation (PTNS) is a percutaneous method of peripheral, sacral neuromodulation. Its current use is limited; however, published data suggest PTNS may be an effective treatment for overactive bladder (OAB).Methods
We systematically reviewed the literature on PTNS for treatment of idiopathic OAB in women from January 2000 to August 2010 published in English in MEDLINE/PubMed, Embase, and Cochrane databases. We included randomized controlled trials or observational studies reporting objective outcome measures with the use of either the Urgent PC or Stoller Afferent Nerve Stimulator (SANS) for PTNS. Studies were considered “good quality” if results from objective measures were provided for ≥20 women, results distinguished between type of OAB symptom, and data were reported separately for female subjects.Results
Of the 136 identified articles, 17 met inclusion criteria for data abstraction; 4 of the 17 studies met our criteria for good quality and reported success rates of 54–93?%. Recurrent limitations in the literature were pooling of results for male and female subjects and lack of differentiation in the data on specific symptoms of OAB treated. Short-term follow-up and infrequent use of a control arm were also noted shortcomings of reviewed studies.Conclusions
Limited high quality data exist on PTNS for OAB in women. Although initial studies have demonstrated promise, more comprehensive evaluation of PTNS is needed to support its universal use for the treatment of OAB in women. 相似文献18.
