Recurrent urinary tract infection management and prevention techniques among a population-based cohort of women.

INTRODUCTION: Recurrent urinary tract infection (rUTI), defined as three or more UTIs in 12 months, has psychological, physical, and financial burden. Many women with rUTI are not satisfied with care and report only starting preventative measures after several infections. The goal of this study is to elucidate current UTI management trends and the implementation of UTI prevention strategies. METHODS: A web-based study was sent to a national sample of adult women enrolled in ResearchMatch.org. Women were recruited to participate if they had a self-reported UTI in the past 12 months. RESULTS: Of the 755 subjects, nearly 30% reported rUTI. Among women with rUTI, more than 50% reported being peri- or postmenopausal, and two-thirds reported vaginal symptoms. 15.8% of women with rUTI reported dissatisfaction with care versus 7.9% of women without rUTI. Most women see their primary care physician for UTI management and only 26% of women with rUTI follow with a urologist. More than 65% of women increase their fluid intake, wipe from front to back, and urinate after sexual activity to prevent UTIs. Significantly more women with rUTI use transvaginal estrogen, cranberry extract, and low-dose prophylactic antibiotics. These interventions appear to be driven by urologists. CONCLUSION: Most women who have had a UTI in the last 12 months implement lifestyle changes to prevent future infections. Most women see their PCP for UTI management and women with rUTI are twice as likely to report dissatisfaction with care. Despite urologists optimizing medical rUTI prevention, they appear to be underutilized.

Clinical hypnosis can reduce lower urinary tract symptoms in individuals with chronic pain.

STUDY PURPOSE: Lower urinary tract symptoms (LUTS) can occur in chronic pain populations at high rates and drastically affect quality of life. Hypnosis is a nonpharmacological treatment used in chronic pain known to have beneficial implications to health outside of pain reduction. This study evaluated the potential for hypnosis to reduce LUTS in a sample of individuals with chronic pain, if baseline LUTS severity affected outcomes, and specific LUTS that may respond to hypnosis. METHODS: Sixty-four adults with chronic pain and LUTS at a level of detectable symptom change (American Urological Association Symptom Index, AUASI 3) participated in an 8-week group hypnosis protocol. Participants completed validated assessments of LUTS, pain, and overall functioning before, after, 3- and 6-months posttreatment. Linear mixed effects models assessed improvement in LUTS over time while accounting for known factors associated with outcome (e.g., age, gender). The interaction of baseline symptom severity and treatment assessed the potential effect of baseline symptoms on change scores. RESULTS: Participants experienced significant and meaningful improvements in LUTS following group hypnosis (p = 0.006). There was a significant interaction between baseline symptom severity and treatment (p < 0.001), such that those with severe symptoms experienced the most pronounced gains over time (e.g., an 8.8 point reduction). Gains increased over time for those with moderate and severe symptoms. Changes in LUT symptoms occurred independently of pain relief. CONCLUSIONS: This pilot study suggests hypnosis has the potential to drastically improve LUTS in individuals with chronic pain, even when pain reduction does not occur. Results provide initial evidence for the treatment potential of hypnosis in urologic pain (and possibly non-pain/benign) populations, with randomized trials needed for definitive outcomes.

Surgery for urinary incontinence in women: Report from the 6th international consultation on incontinence.

Urinary incontinence is a prevalent condition worldwide and causes a tremendous impact on a woman's quality of life. While conservative and non-surgical therapies are options for treatment, surgery for stress urinary incontinence (SUI) is common. Options include colposuspension, slings (pubovaginal and midurethral), and periurethral bulking. While evidence supports each of these options in the treatment of SUI, each is associated with various rates of success and unique adverse event profiles. Urgency urinary incontinence (UUI) is initially treated with behavioral modification and pharmacologic means, with surgery reserved for those with refractory symptoms or significant complications from medication use. At present, intravesical onabotulinumtoxinA injections, percutaneous tibial nerve stimulation, and sacral neurostimulation are all viable options for refractory UUI/overactive bladder. As with surgical interventions for SUI, each of these is, likewise, associated with unique outcomes and adverse event profiles. Herein, we summarize the findings and conclusions from the 6th International Consultation on Incontinence (ICI) regarding surgical treatment of urinary incontinence in women.

Road to recovery after transvaginal surgery for urethral mesh perforation: evaluation of outcomes and subsequent procedures.

INTRODUCTION AND HYPOTHESIS: Urethral injury resulting from transvaginal mesh slings is a rare complication with an estimated incidence of <1%. Our objective was to review the surgical management and functional outcomes of women presenting with urethral mesh perforation following midurethral sling (MUS) placement. METHODS: This was a retrospective multicenter review of women who from January 2011 to March 2016 at two institutions underwent mesh sling excision for urethral perforation with Female Pelvic Medicine and Reconstructive Surgery fellowship-trained surgeons. Data comprising preoperative symptoms, operative details, and postoperative outcomes were collected by telephone (n 13) or based on their last follow-up appointment. RESULTS OBTAINED: Nineteen women underwent transvaginal sling excision for urethral mesh perforation. Eight (42%) patients had undergone previous sling revision surgery. Sixty percent of women had resolution of their pelvic pain postoperatively. At follow-up, 92% reported urinary incontinence (UI), and three had undergone five additional procedures for vaginal prolapse mesh exposure (n 1), incontinence (onabotulinum toxin injection n 1, rectus fascia autologous sling n 1), prolapse (colpopexy n 1), and pain (trigger-point injection n 1). Patient global impression of improvement data was available for 13 patients, of whom seven (54%) rated their postoperative condition as Very much better or Much better. CONCLUSIONS: The management of urethral mesh perforation is complex. Most women reported resolution of their pelvic pain and a high rate of satisfaction with their postoperative condition despite high rates of incontinence.

Cost profiles and budget impact of rechargeable versus non-rechargeable sacral neuromodulation devices in the treatment of overactive bladder syndrome.

OBJECTIVES: Sacral neuromodulation (SNM) is a guideline-recommended third-line treatment option for managing overactive bladder. Current SNM devices are not rechargeable, and require neurostimulator replacement every 3-6 years. Our study objective was to assess potential cost effects to payers of adopting a rechargeable SNM neurostimulator device. METHODS: We constructed a cost-consequence model to estimate the costs of long-term SNM-treatment with a rechargeable versus non-rechargeable device. Costs were considered from the payer perspective at 2015 reimbursement levels. Adverse events, therapy discontinuation, and programming rates were based on the latest published data. Neurostimulator longevity was assumed to be 4.4 and 10.0 years for non-rechargeable and rechargeable devices, respectively. A 15-year horizon was modeled, with costs discounted at 3% per year. Total budget impact to the United States healthcare system was estimated based on the computed per-patient cost findings. RESULTS: Over the 15-year horizon, per-patient cost of treatment with a non-rechargeable device was $64,111 versus $36,990 with a rechargeable device, resulting in estimated payer cost savings of $27,121. These cost savings were found to be robust across a wide range of scenarios. Longer analysis horizon, younger patient age, and longer rechargeable neurostimulator lifetime were associated with increased cost savings. Over a 15-year horizon, adoption of a rechargeable device strategy was projected to save the United States healthcare system up to $12 billion. CONCLUSIONS: At current reimbursement rates, our analysis suggests that rechargeable neurostimulator SNM technology for managing overactive bladder syndrome may deliver significant cost savings to payers over the course of treatment.

Evaluation of the axonics modulation technologies sacral neuromodulation system for the treatment of urinary and fecal dysfunction.

INTRODUCTION: Sacral neuromodulation (SNM) remains one of the few effective treatments for refractory bladder and bowel dysfunction. However, SNM is associated with frequent need for surgical intervention, in many cases because of a failed battery. A rechargeable SNM system, with a manufacturer-reported battery life of 15 years or more, has entered post-market clinical testing in Europe but has not yet been approved for clinical testing in the United States. Areas covered: We review existing neuromodulation technologies for the treatment of lower urinary tract and bowel dysfunction and explore the limitations of available technology. In addition, we discuss implantation technique and device specifications and programming of the rechargeable SNM system in detail. Lastly, we present existing evidence for the use of SNM in bladder and bowel dysfunction and evaluate the anticipated trajectory of neuromodulation technologies over the next five years. Expert commentary: A rechargeable system for SNM is a welcome technological advance. However surgical revision not related to battery changes is not uncommon. Therefore, while a rechargeable system would be expected to reduce costs, it will not eliminate the ongoing maintenance associated with neuromodulation. No matter the apparent benefits, all new technologies require extensive post-market monitoring to ensure safety and efficacy.

New evidence in the treatment of overactive bladder.

PURPOSE OF REVIEW: Overactive bladder (OAB) in women is highly prevalent. It can be very bothersome and affect quality of life. Treatment differs significantly depending on the clinical presentation, and includes behavioural modification, medicinal therapies and surgical procedures. New treatment options have become available in recent years, and can offer great benefit to patients with persistent, bothersome OAB. RECENT FINDINGS: First-line management for OAB consists of lifestyle and behavioural therapy, followed by antimuscarinic therapy or oral beta-3 agonists. Sacral neuromodulation, onabotulinumtoxinA and posterior tibial nerve stimulation are additional well tolerated and efficacious treatment options that should be considered in carefully selected, refractory OAB patients. These recent advances in OAB therapy are discussed in this review. SUMMARY: The treatment of OAB is often complex, and can require trials of multiple different treatment modalities. Although the treatment advances discussed in this review have augmented treatment of OAB, the condition continues to negatively impact quality of life for our ageing female population. Clinical trials and development of novel therapies continue to be paramount.

The role of electrical stimulation techniques in the management of the male patient with urgency incontinence.

PURPOSE OF REVIEW: Overactive bladder affects 10-27% of men, a significant portion of whom report urge urinary incontinence that is inadequately treated with first-line and second-line treatments. There is thus a substantial need to critically evaluate the alternative means of clinical management. RECENT FINDINGS: This review presents the current evidence for the use of sacral neuromodulation and percutaneous tibial nerve stimulation in the treatment of men with urge incontinence, as well as evaluates the financial implications of these treatments. Other alternative modes of electrical stimulation for urge incontinence are also briefly reviewed. SUMMARY: Both sacral neuromodulation and percutaneous tibial nerve stimulation prove to be viable, durable options for treating patients with refractory urge incontinence. Alternative modes of stimulation are also beginning to show promise.

Evaluation of fesoterodine fumarate for the treatment of an overactive bladder.

INTRODUCTION: Fesoterodine fumarate is an approved drug for overactive bladder. The aim of this study is to review the preclinical and most up to date clinical data on fesoterodine, with a special emphasis on its unique pharmacokinetic features and its implications on safety and tolerability in various patient populations. AREAS COVERED: In this review, the authors extensively reviewed available literature via PubMed search regarding fesoterodine, covering its mechanism of action, pharmacodynamics and pharmacokinetics, clinical efficacy, safety, and tolerability. EXPERT OPINION: Fesoterodine is an anti-muscarinic agent with a unique pharmacokinetic profile. It is a prodrug that is rapidly metabolized to its active form by nonspecific plasma esterases. Its metabolism is independent of the cytochrome P450 enzyme system. This along with its dual excretion pathways and minimal central nervous system penetration leads to less variability in drug exposure and allowance of administration in those with mild to moderate renal and hepatic insufficiency and in the geriatric population.

Pelvic organ prolapse (POP) surgery: the evidence for the repairs.

What is known on the subject? and What does the study add? Substantial experience of the outcomes has been gathered regarding the acute and sub-acute experience with various types of corrective procedures for POP. These include long-term POP correction as well as more recent recognition of improvement in functional disorders associated with POP such as UI, colorectal dysfunction, and sexual dysfunction. Long-term follow-up is available for some of the older types of interventions and current multicentre trials are being accrued with longer term follow-up for new interventions including mesh-type repairs. The study adds a condensed and summarized version of the current literature regarding the various interventions for POP and also provides an overview of the current controversies and areas where knowledge is incomplete and in need of further elaboration for definitive answers regarding optimization of surgical care for POP. Our aim is to summarise the available data on the transvaginal placement of synthetic mesh for pelvic organ prolapse (POP) repair, with a focus on the outcomes and complications of commercial POP-repair kits. As the stability and durability of autologous tissues may be questionable, nonabsorbable, synthetic materials are an attractive alternative for providing additional support during POP surgery. These materials are not novel, and most have been used for many years in surgical applications, e.g. hernia repairs. While theoretically appealing, the implantation of synthetic mesh in the pelvis may be associated with inherent adverse consequences, such as erosion, extrusion, and infection. Additionally, the routine use of these materials may carry potential long-term complications, such as dyspareunia, chronic pelvic pain, and vaginal distortion. The success and failure of mesh-augmented POP repair is related not only to the synthetic material itself, but also to patient- and surgeon-related factors. Recent warnings by the USA Food and Drug Administration and other groups regarding adverse events further complicate the decision to use synthetic mesh.

Update on the treatment of overactive bladder.

PURPOSE OF REVIEW: As overactive bladder (OAB) is a prevalent and chronic medical condition that greatly impacts an individual's quality of life, novel therapeutic options are always welcome. RECENT FINDINGS: Recent evidence suggests that newer antimuscarinic agents are not only superior to placebo, but may also have a role in treating OAB symptoms in children and men with lower urinary tract symptom. Dose escalation for trospium and fesoterodine has shown to be both efficacious and safe. Adverse events typically exceed those of placebo but infrequently lead to cessation of therapy. Long-term outcomes of sacral nerve stimulation for refractory OAB have been recently reported. Although the overall satisfaction with this therapy is high, more than 50% may experience chronic pain; however, this adverse event also does not frequently lead to device removal. Percutaneous tibial nerve stimulation continues to display superiority to sham treatment and benefits similar to antimuscarinic therapy may be observed. This therapy is well tolerated and durable outcomes have been seen at 12 months of follow-up. Recent evidence suggests that a dose of 100 U per botulinum neurotoxin type A injection may optimally balance symptom improvement and incidence of voiding difficulty. SUMMARY: Treatment modalities for OAB continue to evolve and the abundance of options can only benefit the individuals with this condition.

Refractory overactive bladder after urethrolysis for bladder outlet obstruction: management with sacral neuromodulation.

Refractory overactive bladder (OAB) after urethrolysis for iatrogenic bladder outlet obstruction (BOO) is a clinical dilemma without established guidelines for management. We sought to evaluate the efficacy of sacral neuromodulation (SNM) in the management of this complex patient population. Retrospective review identified eight patients who underwent SNM secondary to refractory OAB after urethrolysis or sling take-down. SNM was performed with the Interstim device (Medtronic, Minneapolis) using a two-stage implant technique. SNM outcomes were determined subjectively during follow-up. Validated questionnaires were completed to assess symptom bother, patient satisfaction, and quality of life. Statistical analyses were conducted using Stata version 9.0. Six patients had a favorable response to SNM during test stimulation and underwent implantation of the implantable pulse generator (IPG). With follow-up of 15.7 +/- 11.1 months (6-34), all patients significantly improved, with three patients being dry and three patients having one to two urgency incontinence episodes per week. Patient-reported outcomes indicated that patients perceived themselves as very much improved (3) or much improved (3) after SNM, while those failing test stimulation perceived no change. Quality of life and symptom bother were significantly better in SNM responders vs nonresponders. SNM appears to be an effective and viable treatment option in this complex patient population. Further work is needed to determine clinical factors predictive of outcome and durability of response.

Management of refractory urinary urge incontinence following urogynecological surgery with sacral neuromodulation.

AIMS: We sought to explore our patient outcomes utilizing sacral neuromodulation in the management of refractory urinary urge incontinence following urogynecological surgical procedures. METHODS: A total of 25 women with urinary urge incontinence following urogynecological surgery were selected for SNS therapy and retrospectively analyzed. All patients completed a comprehensive urological evaluation. Clinical data was recorded to determine outcomes and identify parameters that would be predictive of response to neuromodulation. Outcomes were determined via subjective patient questionnaire and graded as follows: significant response (> or =80% improvement), moderate response (> or =50% and <80% improvement), and poor response (<50% response). RESULTS: Nineteen patients had a previous pubovaginal sling (10 with concomitant pelvic prolapse repair), 3 a previous retropubic suspension, and 3 a transperitoneal vesicovaginal fistula repair. Urethrolysis was performed in 4 patients to alleviate bladder outlet obstruction prior to sacral neuromodulation. Mean patient age was 59.8 years and length of follow-up was 7.2 months. Twenty-two women (88%) had the IPG placed during a Stage 2 procedure. Twenty patients maintained at least a 50% improvement in clinical symptoms at last follow-up and 6 patients were continent. Overall, the number of pads/day improved from 4.2 to 1.1 (P < 0.001). There were no significant differences in response to neuromodulation based upon age, duration of symptoms, type of surgery, or urodynamic parameters. CONCLUSION: Sacral neuromodulation appears to be an effective therapy in patients with refractory urge incontinence following urogynecological surgery. Larger prospective studies with longer follow-up are needed to assess the durability of this therapeutic modality.
