Abstract
The objective of the article is to review key guidelines on the management of urinary incontinence (UI) to guide clinical management in a practical way. Guidelines produced by the European Association of Urology (updated in 2014), the Canadian Urological Association (updated in 2012), the International Consultation on Incontinence (updated in 2012), and the National Collaborating Centre for Women's and Children's Health (updated in 2013) were examined and their recommendations compared. In addition, specialised guidelines produced by the collaboration between the American Urological Association and the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction on overactive bladder and the use of urodynamics were reviewed. The Appraisal of Guidelines for Research and Evaluation II (AGREE) instrument was used to evaluate the quality of these guidelines. There is general agreement between the groups on the recommended initial evaluation and the use of conservative therapies for first-line treatment, with a limited role for imaging or invasive testing in the uncomplicated patient. These groups have greater variability in their recommendations for invasive procedures; however, generally the mid-urethral sling is recommended for uncomplicated stress UI, with different recommendations on the approach, as well as the comparability to other treatments, such as the autologous fascial sling. This 'Guideline of Guidelines' provides a summary of the salient similarities and differences between prominent groups on the management of UI.

Abstract
INTRODUCTON Sacral neuromodulation (SNM) has become an established therapy for voiding dysfunction. Additional benefits, such as improved bowel functions and bladder pain, have been reported. Improvement in female sexual function after SNM treatment has been suggested; however, reports examining the effects of SNM on female sexual functions are scarce. We evaluate the effects of SNM on female sexual function and its impact on quality of life and analyze any correlation. METHODS Data were collected from January 2010 to May 2012 for all female patients who underwent SNM InterStim (Medtronic, Minneapolis, MN) therapy at a single centre in Canada. They were treated for voiding dysfunction, including refractory over-active bladder, frequency-urgency syndrome and non-obstructive urinary retention. Patients were screened by percutaneous nerve evaluation (PNE) to assess their response to therapy using a 4-day voiding diary. Patients who experienced 50% or more improvement in their voiding parameters were permanently implanted. All patients completed the Female Sexual Function Index (FSFI), Short-Form Health Survey (SF-36), and incontinence questionnaires (Urinary Distress Inventory [UDI]-6) preoperatively and 4 months postoperatively. RESULTS A total of 33 female patients had SNM therapy; 10 were excluded from the study because they were not sexually active. The indications were: refractory overactive bladder in 19, frequency-urgency syndrome in 2, and non-obstructive urinary retention in another 2 patients. SNM therapy significantly improved the total FSFI score (p = 0.011); the components of desire and orgasm showed significant improvement (p = 0.014 and p = 0.035, respectively). Age, body mass index, diagnosis, and urinary symptoms did not show significant correlation with FSFI score improvement. Quality of life showed significant improvement after SNM treatment in 5 categories. There was no correlation between improvement in quality of life and FSFI. CONCLUSION SNM may improve female sexual function and quality of life, yet there is no correlation between the improvement in FSFI and quality of life.

Abstract
Urinary incontinence is a common condition, which, although not life-threatening, impairs the health-related quality of life of affected individuals. All women complaining of incontinence require a basic assessment and those with complex or refractory symptoms may benefit from urodynamic studies. Initial treatment includes lifestyle advice, behavioral modifications, bladder retraining and pelvic floor muscle training. For those women with persistent stress urinary incontinence following conservative therapy, surgical management might be considered. The development of the minimally invasive, retropubic, synthetic, mid-urethral sling procedures has revolutionized stress incontinence surgery and reduced the popularity of 'traditional' procedures, such as colposuspension and autologous fascial sling. In an attempt to reduce further the morbidity, transobturator and single-incision slings have been introduced. While antimuscarinic agents are the mainstay of the current medical management of urgency urinary incontinence, a recently developed selective β3-adrenergic receptor agonist (mirabegron) offers an alternative pharmacological option. Modalities such as intravesical botulinum toxin and neuromodulation (peripheral or sacral) are available to women with refractory urgency incontinence. Finally, when all other options have been explored and proven unsuccessful, inappropriate or not feasible, reconstructive surgery or catheter insertion might be considered as a last resort. The aim of this paper is to review conservative, medical and surgical management for urinary incontinence by using the best available evidence in the literature.

Abstract
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.

Abstract
OnabotulinumtoxinA injection is a safe and effective treatment for adults with refractory overactive bladder. There is sufficient level 1 evidence to support offering onabotulinumtoxinA injections as a second-line treatment to patients who have failed behavioral therapy and oral medications such as antimuscarinics and β3 agonists. An intradetrusor injection of 100 U of onabotulinumtoxinA is likely the optimal dose to balance risks and benefits, and this is the dose approved by the US Food and Drug Administration. Improvement in urgency urinary incontinence episodes, as well as symptom scores and quality of life, were seen in around 60%-65% of patients, and were significantly improved compared with those on placebo. Most studies have reported a duration of symptom relief ranging from 6 to 12 months, with repeat injections being safe and efficacious. Overall, the risk of urinary retention was around 6% across the study populations.

Abstract
Overactive bladder (OAB) is a symptom complex of urinary frequency, nocturia and urgency with or without urgency incontinence that adversely impacts patient's quality of life. Conservative management begins in the outpatient clinic, often with significant improvement and patient satisfaction. In this review we will discuss the evaluation of OAB and review treatment options focusing on behavioral modification, medical therapy, and neuromodulation. These treatment options are offered in a stepwise fashion, remembering that more than one may be needed and can be used concomitantly.

Abstract
OBJECTIVE To report our long-term experience of sacral neuromodulation (SNM) for various lower urinary tract dysfunctions but with a focus on efficacy, safety, re-interventions and degree of success. PATIENTS AND METHODS This is a single tertiary referral centre study that included 217 patients (86% female) who received an implantable pulse generator (IPG) (Interstim™, Medtronic, Minneapolis, USA) between 1996 and 2010. Success was considered if the initial ≥50% improvement in any of primary voiding diary variables persisted compared with baseline, but was further stratified. RESULTS The mean duration of follow-up was 46.88 months. Success and cure rates were ≈70% and 20% for urgency incontinence, 68% and 33% for urgency frequency syndrome and 73% and 58% for idiopathic retention. In those patients with an unsuccessful therapy outcome, the mean time to failure was 24.6 months after implantation. There were 88 (41%) patients who had at least one device or treatment related surgical re-intervention. The re-intervention rate was 1.7 per patient with most of them (47%) occurring ≤2 years of follow-up. CONCLUSIONS SNM appears effective in the long-term with a success rate after definitive IPG implant of ≈70% and complete cure rates ranging between 20% and 58% depending on indication. Patients with idiopathic retention appear to do best. The re-intervention rate is high with most occurring ≤2 years of implantation. It is likely that with the newer techniques used, efficacy and re-intervention rates will improve.

Abstract
INTRODUCTION Neural stimulation has become an established minimally invasive treatment for various lower urinary tract symptoms. The results both short- and long-term are encouraging, however, there is still a lack of knowledge of obvious risk factors, which may affect the outcome of treatment. Although neural stimulation has been embraced by healthcare professionals and patients, the exact mechanism by which neural stimulation works is still unclear. DISCUSSION A condense review of knowledge available on this topic is presented. Several research questions are raised. Outlines of research studies, both clinical and basic science, are suggested. CONCLUSIONS Further studies are necessary to understand mechanism of action of neural stimulation and its implications on treatment outcomes.

Abstract
Urinary incontinence is a common and distressing condition, which, although not life-threatening, is known to have a significant effect on quality of life. The incidence of urinary incontinence increases with age and while stress urinary incontinence is more common in younger women, symptoms suggestive of overactive bladder are more common with increasing age. All women complaining of incontinence require simple investigation, and many will benefit from conservative and medical treatments, which may be instituted in primary care. Further investigation in the secondary-care setting should be reserved for those women with refractory or unusual symptoms. The aim of this paper is to review the epidemiology and pathophysiology of common causes of urinary incontinence in younger, premenopausal women, and to review the current algorithms for investigation and management. In addition, treatment paradigms covering conservative, medical and surgical treatment for stress urinary incontinence and overactive bladder will be reviewed.

Abstract
PURPOSE We evaluated whether patients with overactive bladder and incontinence who discontinued intravesical botulinum toxin therapy can be successfully treated with sacral neuromodulation. MATERIALS AND METHODS All patients who were referred to our center after discontinuation of botulinum toxin-A between 2005 and 2010 were included in this observational study. All patients underwent test stimulation with sacral neuromodulation and were evaluated with voiding diaries. Success was defined as more than 50% improvement in leakage episodes. Successful test stimulation was subsequently followed by a definitive implant. Patient satisfaction with sacral neuromodulation therapy was evaluated 1 year after the definitive implant. RESULTS A total of 20 patients were included in the study. Of these patients 17 (85%) had discontinued botulinum toxin-A because of lack of efficacy and 3 had been treated successfully with botulinum toxin-A but requested a more permanent solution. The mean interval between the botulinum toxin-A and the sacral neuromodulation test stimulation was 23 months. In 14 patients (70%) the test stimulation was successful and they received a definitive implant. Of the 14 patients 5 even showed a decrease of greater than 90% in leakage episodes. One year after implantation 11 patients (79%) were satisfied with the sacral neuromodulation treatment. CONCLUSIONS Despite the small sample size, this study indicates that patients who are dissatisfied with or in whom botulinum toxin-A treatment fails can respond successfully to sacral neuromodulation. The success rate of the test stimulation was comparable to that of patients who have never been treated with botulinum toxin-A. The 1-year satisfaction rate was comparable that of patients without a history of botulinum toxin-A treatment.

Abstract
Overactive bladder (OAB) affects millions of people worldwide yet first-line treatments are often poorly tolerated and compliance rates are low. Neuromodulation works via afferent nerve modulation and offers a minimally invasive and reversible alternative treatment option for patients with OAB who have failed first-line therapy. Neuromodulation has revolutionized the management of OAB and is now well established as a safe and effective treatment for those refractory to conservative treatments. Multiple neuroanatomical pathways have been described for sacral neuromodulation including the S3 nerve root, pudendal nerve and tibial nerve. The S3 nerve root is currently the main treatment target and has the most long-term data on safety and efficacy to support its use. However, studies on neuromodulation at the pudendal nerve or posterior tibial nerve have been positive and their role in treatment continues to evolve. Most urologists who are experienced in voiding dysfunction can become proficient in each technique. Patient selection, surgical techniques and postoperative management differ slightly between approaches and urologists should familiarize themselves with these differences. Treatment of OAB should progress from the least to most invasive modality, and neuromodulation provides an attractive option owing to its minimally invasive approach, tolerability, positive outcomes and reversibility.

Abstract
Sacral nerve stimulation (SNS) has become an established treatment option for patients with intractable detrusor overactivity and non-obstructive urinary retention. The Scottish Sacral Nerve Stimulation service was established in April 2010 to provide a service for the population of Scotland. We report our experience from the first year of this new national service. All patients referred for SNS from the inception of the service in April 2010 until the end of March 2011 were studied. During the one-year period, there were 50 referrals. Thirty-three percutaneous nerve evaluations, eight tined lead tests and 16 permanent implantation procedures were performed during this period. Morbidity was low and both incontinence and quality-of-life questionnaires demonstrated statistically significant improvements (International Consultation on Incontinence Questionnaire [ICIQ-SF], P = 0.005; Incontinence Impact Questionnaire [IIQ 7], P = 0.0007; Urogenital Distress Inventory [UDI 6], P = 0.0002). Referral pattern was skewed towards the west of Scotland with some health boards producing no referrals during the year. Results from the first year of the service have shown that it is a safe and efficient procedure with significant improvement in incontinence, voluntary voiding and quality-of-life parameters. The limitation of funding for permanent implants inevitably impacts on the role of the technique as a management option in these patients.

Abstract
Overactive bladder (OAB) is a clinical syndrome describing the symptom complex of urgency, with or without urgency incontinence and is usually associated with frequency and nocturia. Whilst many women may be initially managed using a clinical diagnosis alone a number will fail primary therapy and will require further investigation. Those women with refractory symptoms following initial conservative and medical therapy may benefit from alternative treatment modalities including intravesical Botulinum toxin, neuromodulation or reconstructive surgery. This review, the second of two covering the treatment of intractable OAB symptoms in women, will focus on management following the failure of medical therapy. It will principally focus on the role of Botulinum toxin, neuromodulation and reconstructive surgery.

Abstract
BACKGROUND Sacral nerve stimulation is a recognized treatment for fecal and urinary incontinence. Few articles have been published about patients presenting with both types of incontinence. OBJECTIVE The aim of this study was to report the functional results in patients operated on for simultaneous fecal and urinary incontinence by the use of sacral nerve stimulation. DESIGN This study is a retrospective analysis of prospectively collected data. SETTINGS The investigation was conducted in the academic departments of colorectal surgery and urology. PATIENTS Between January 2001 and March 2010, 57 consecutive patients (54 women) with a mean age of 58 years (range, 16-76) were included. INTERVENTIONS Two-stage sacral nerve modulation (test and implant) was performed. MAIN OUTCOME MEASURES Functional study before testing, at 6 months, and at the end of follow-up after implantation included the use of the Cleveland Clinic incontinence score, Urinary Symptoms Profile, Fecal Incontinence Quality of Life score, and the Ditrovie score. Patient satisfaction with the technique was evaluated at a median follow-up of 62.8 months. RESULTS : Fecal incontinence improved from 14.1/20 to 7.2/20 at 6 months and 6.9/20 at the end of follow-up. Urinary incontinence, mainly urge incontinence (47% of patients), and urgency frequency (34% of patients) improved at 6 months and end of follow-up, but not retention and dysuria. Specific quality of life was improved for fecal and urinary incontinence at 6 months and end of follow-up. At the end of follow-up, 73% patients were highly satisfied with the technique, but 9% felt their condition had deteriorated. The reoperation rate was 29%, of which 12% were indicated because of a complication. LIMITATIONS This study was limited by its retrospective nature and the multiple causes of incontinence. CONCLUSION Fecal and urinary incontinence, studied by symptoms scores and specific quality-of-life scores, are improved in patients receiving sacral nerve stimulation for double incontinence.

Abstract
BACKGROUND Neurogenic bladder associated with spinal cord injury (SCI) often results in serious disruption of lower urinary tract function. Compared to conventional therapies, sacral neuromodulation (SNM) may offer an alternative, non-destructive treatment for SCI patients with bladder dysfunction. Understanding bladder reflex changes following SCI and the effects of SNM may yield new insights for innovative use of this promising technique. Using a SCI rat model developed in this study, we investigated: 1) the bladder responses with different grades of bladder filling in intact and SCI rats; and 2) the effects of acute SNM on bladder reflex responses in SCI rats. METHODS An SCI rat model with overactive bladder was developed and evaluated in this study to examine the effects of acute SNM on bladder reflex in complete SCI rats. Twelve adult female Sprague-Dawley rats were divided into three groups; group I: spinally intact rats (N = 4), group II: transected (T9-T10) rats (N = 4), i.e., SCI rats, and group III: SCI rats with SNM treatment (N = 4). All rats were anesthetized and set up for continuous saline infusion. Cystometric parameters, including contraction period, contraction duration, bladder peak pressure, and number of uninhibited contractions, were analyzed and compared between groups and between conditions with and without SNM treatment for SCI rats. RESULTS In the intact rats, the frequency of bladder contraction was dependent upon the rate of bladder filling, while the spinal transected rats exhibited large fluctuation and demonstrated different patterns in response to saline infusion. Moreover, the bladder in SCI rats demonstrated an increased contraction period and a decreased contraction strength compared to the intact rats (all p < 0.05). In SCI rats under acute SNM treatment, bladder contraction period and duration tended to become longer, and the bladder peak pressure was decreased. The accumulating evidence indicated that acute SNM had inhibiting effects for bladder overactivity following SCI. CONCLUSION The spinal rat model developed in this study was suitable to investigate the effect of sacral neural stimulation on micturition reflex. The results of present study demonstrated that the micturition reflex can be modulated by sacral neural stimulation.
