The use of electrical devices for the treatment of bladder dysfunction: a review of methods.

Contains fulltext : 59295.pdf (publisher's version ) (Closed access)PURPOSE: We reviewed the literature on the application of various devices and techniques for the electrical stimulation treatment of lower urinary tract dysfunction with respect to mechanism of action and clinical outcome. MATERIALS AND METHODS: A systematic review was done in PubMed of publications on intravesical stimulation, direct bladder stimulation, stimulation of the pelvic and pudendal nerves, transcutaneous-electrical nerve stimulation, stimulation of the sacral spine and roots, and lower limb stimulation. RESULTS: It is difficult truly to compare different treatment modalities because there are hardly any randomized placebo controlled studies. Also, there is considerable variety in treatment parameters and schedules reported as well as in criteria for success. Nevertheless, it can be said that electrical neurostimulation and neuromodulation result in a 30% to 50% clinical success on an intent to treat basis. Influencing lower urinary tract innervation at the level of sacral roots seems successful in neurological and nonneurological cases. It has the advantage of pretesting possibilities to improve patient selection and treatment outcome with the obvious drawback of invasiveness. Noninvasive techniques lack screening tests, making patient selection a matter of trial and error, and when there is success patients almost always need maintenance therapy. CONCLUSIONS: Randomized clinical trials to compare different techniques and evaluate placebo effects are urgently needed, as are further studies to elucidate modes of action to improve stimulation application and therapy results. The introduction of new stimulation methods may provide treatment alternatives as well as help answer more basic questions on electrical neurostimulation and neuromodulation

Long-term real-life adherence of percutaneous tibial nerve stimulation in over 400 patients

Contains fulltext : 219864.pdf (Publisher’s version ) (Open Access)BACKGROUND: Percutaneous tibial nerve stimulation (PTNS) is used as a treatment to reduce the complaints of overactive bladder (OAB). Although it is rewarding therapy patients need maintenance treatment to preserve the beneficial effect. AIM: This real-life retrospective study was performed to assess the feasibility of PTNS adherence. MATERIALS & METHODS: All patients who underwent PTNS were retrospectively included. We analyzed the following: indication, kind of treatments (pharmacologic and third-line therapy) before and after PTNS treatment, time and reason for quitting therapy. Statistical analysis was done by performing competitive-risk analysis and Kaplan-Meier curves. Patients were categorized into four groups. Group 1: all patients; group 2: all patients on maintenance PTNS therapy (continuing after 12 weeks); group 3: patients on maintenance PTNS therapy excluding the following: (a) patients with initial good response who seized treatment due to death, (b) patient who successfully switched to transcutaneous stimulation, (c) patients who were cured of their OAB symptoms, or (d) patients who relocated; and group 4: group 3 but excluding those who stopped treatment because of nonmedical reasons (physical strain, inconveniencies associated with visiting the hospital). RESULTS: Four-hundred two patients (70% female) with a median age of 70 years underwent PTNS. Underlying treatment indications were: OAB-wet (54%) and OAB-dry (29%). The median follow-up (FU) of group 1 was 4 months. Fifty-seven percent (N = 228) of the patients received maintenance PTNS therapy. Median FU in group 4 was 46 months (range, 3-111 months). Over 40% of the maintenance patients stopped PTNS because of logistic reasons and physical strain during an FU time of 6 years. CONCLUSION: The real-world data described here with is in line with earlier published work in terms of the success rate of OAB treatment. However, over 40% quit their therapy due to nonmedical reasons

Tibial nerve stimulation in the treatment of overactive bladder syndrome: technical features of latest applications

Contains fulltext : 220577.pdf (Publisher’s version ) (Open Access)PURPOSE OF REVIEW: Overactive bladder syndrome (OAB) is a chronic condition, which can be treated by tibial nerve stimulation. The present review will focus on the technical aspects, advantages, drawbacks, and limitations of the latest available applications of posterior tibial nerve stimulation. RECENT FINDINGS: We describe the technical aspects of recent developed implants and techniques of tibial nerve stimulation in a transcutaneous, percutaneous, and minimal invasive way. All different treatment options have advantages and disadvantages based on type of surgery, energy transfer, impedance, treatment setting options, risk of migration, and patient usability, which are described in this review. Only devices with data that are publicly available were included. SUMMARY: New technologies are on their way in the field of tibial nerve stimulation for the treatment of OAB. Technical aspects are important to demonstrate safety and efficacy and user friendliness in order to obtain high acceptance of the various devices

Correlation between quality of life and voiding variables in patients treated with percutaneous tibial nerve stimulation.

Contains fulltext : 51186.pdf (publisher's version ) (Closed access)OBJECTIVE: To investigate the relationship between quality of life (QoL) and voiding variables in patients with lower urinary tract dysfunction treated with percutaneous tibial nerve stimulation (PTNS), as it is assumed that improvements in voiding will lead to a better QoL in such patients. PATIENTS AND METHODS: The study included 30 patients with urge urinary incontinence who were treated with PTNS; 24-h bladder diaries and QoL questionnaires (Short Form, SF-36, and incontinence-specific QoL) were completed at baseline and after PTNS. RESULTS: There was a significant correlation (P or = two pads/day before their QoL improves, and this might be the best definition of successful therapy for patients with urge urinary incontinence
