Abstract
Much of the debate over the use of transvaginal mesh for incontinence and prolapse has been conducted on social media, in the tabloid press and through a very public Senate inquiry. It has been a very emotionally charged debate with surgeons variously accused of scandalous behavior, financial impropriety, surgical experimentation and misogyny. What really happened, how did we get here and what can we learn from these complex events?

Abstract
AIMS In late-onset Pompe disease (LOPD), a lysosomal storage disorder with glycogen accumulation in several tissues, patients suffer from progressive skeletal muscle weakness. Lower urinary tract symptoms (LUTS) have rarely been reported. The aim of this study is to objectively assess LUTS in patients with LOPD for the first time using urodynamic studies and to determine differences between LOPD patients with and without LUTS. METHODS Eighteen patients with LOPD were recruited, of whom seven patients (38.9%) reported LUTS (both voiding and storage symptoms). Six of these patients underwent urodynamic studies. Medical histories and motor function tests were compared between the 7 patients with LUTS and the 11 patients without LUTS. The Student t test was used to determine an association between the two cohorts. RESULTS In the seven LOPD patients with LUTS urodynamics revealed neurogenic dysfunction, underactive detrusor, and bladder outlet obstruction. These patients had suffered from clinical symptoms for a longer period of time before starting enzyme replacement therapy (P = .017) than patients without LUTS. They also scored more poorly on muscle function tests. Urodynamic results point to neurogenic causes for LUTS in LOPD, that is, neurogenic reflex bladder or impaired filling sensation. This could be due to glycogen accumulation in the urothelium and central nervous system. Patients with LUTS also seem to be more severely affected by LOPD than patients without LUTS. CONCLUSION LUTS in LOPD requires early and specific treatment to limit the development of severe health problems. Urodynamic studies should be considered in assessing LUTS.

Urinary Incontinence in Women: Modern Methods of Physiotherapy as a Support for Surgical Treatment or Independent Therapy. J Clin Med 2020; 9:jcm9041211. [PMID: 32340194 PMCID: PMC7230757 DOI: 10.3390/jcm9041211] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 04/20/2020] [Accepted: 04/20/2020] [Indexed: 12/12/2022] Open
Abstract
Urinary incontinence (UI) is a common health problem affecting quality of life of nearly 420 million people, both women and men. Pelvic floor muscle (PFM) training and other physiotherapy techniques play an important role in non-surgical UI treatment, but their therapeutic effectiveness is limited to slight or moderate severity of UI. Higher UI severity requires surgical procedures with pre- and post-operative physiotherapy. Given that nearly 30%–40% of women without dysfunction and about 70% with pelvic floor dysfunction are unable to perform a correct PFM contraction, therefore, it is particularly important to implement physiotherapeutic techniques aimed at early activation of PFM. Presently, UI physiotherapy focuses primarily on PFM therapy and its proper cooperation with synergistic muscles, the respiratory diaphragm, and correction of improper everyday habits for better pelvic organ support and continence. The purpose of this work is a systematic review showing the possibilities of using physiotherapeutic techniques in the treatment of UI in women with attention to the techniques of PFM activation. Evidence of the effectiveness of well-known (e.g., PFM training, biofeedback, and electrostimulation) and less-known (e.g., magnetostimulation, vibration training) techniques will be presented here regarding the treatment of symptoms of urinary incontinence in women.

Abstract
Bladder exstrophy-epispadias complex (EEC) is a rare congenital defect where the abdominal muscles and bones fail to close in the mid-pelvis. It is crucial to understand the health-related quality of life (QOL) of exstrophy patients who have undergone multiple correctional surgeries. We herein discuss a case of bladder EEC that was repaired through a series of procedures at a resource-limited hospital in Karachi, Pakistan. A 21-year-old male, who was born with EEC, underwent bladder augmentation, Mitrofanoff procedure, bladder neck reconstruction, ureter implantation and a right nephrectomy in a single one-stage procedure during late childhood for urinary incontinence. However, this required a further revision because the urinary incontinence persisted, with difficulty in catheterizing the Mitrofanoff channel. On follow-up after 10 years, our patient currently describes normal QOL with near-normal sexual function. Validated questionnaires for QOL, erectile dysfunction, incontinence and prostatic function were used to assess the patient's post-operative status in these domains. Through our report, we conclude that such patients can have a normal QOL by means of a holistic multidisciplinary management, which includes timely surgical corrections along with an additional focus on the psycho-social and sexual aspects of this condition.

Abstract
Objective: The aim of this study was to determine the frequency of pelvic floor dysfunction (PFD) symptoms experienced the first year of postpartum and obstetric risk factors. Methods: This research was a cross-sectional descriptive study. The study was conducted with 408 women between 3 and 12 months postpartum, in İzmir. Results: It was found that urinary incontinence had been experienced by 33.3% of the women during pregnancy and 25.2% postpartum and 2.9% had experienced fecal incontinence. Other frequently experienced symptoms of PFD were in the order of frequency, perineal pain (53.4%), constipation (40.7%), flatulence (34.1%), dyspareunia (27.7%) and fecal incontinence (2.9%). Conclusion: PFD symptoms are common in postpartum women. Early diagnosis, treatment and preventive approaches should be made by healthcare professionals for perinatal pelvic floor health. Impact statement: Healthcare professionals should acknowledge the importance of PFD after birth and identify the problems early period. Our study emphasizes the size of the problem and improvement for PFD.

Abstract
An artificial sphincter is a device that replaces the function of the biological sphincter by occluding the relative biological lumen. The investigation of occlusion methods for artificial sphincters is crucial for a reliable and effective design of such devices. The compression induced onto the tissue by a certain pressure depends on the biomechanical and physiological features of the lumen and on the specific occlusion method. A numerical model and an experimental evaluation are presented here to assess the efficiency of different occlusion methods. Numerical models of circumferential occlusion and clamping occlusion methods to simulate the compression of the biological lumen were developed. Results revealed a relationship between the efficiency of the occlusion method and the physiological condition of the lumen. With differences related to the testing setup, this relationship was also confirmed experimentally by conducting tests on biological simulators. We analyzed the occlusion method to adopt as the physiological pressure (ie, leakage pressure values) changed. In particular, we focused on the urinary incontinence, which is a dysfunction involving the external sphincter surrounding the urethra. In this scenario, we demonstrated that a clamping occlusion is an efficient method to compress the urethra, whose physiological pressures range between 4 and 12 kPa. The clamping occlusion method resulted up to 35% more efficient in terms of sealing pressure than the circumferential one for a closing pressure varying between 2.3 and 11.5 kPa.

Abstract
Purpose For successful long-term rehabilitation of patients with neurogenic lower urinary tract dysfunction (NLUTD), it is necessary to define the objective requirement for urological aids based on a scientifically validated basis. Methods This was a cross-sectional multicenter study, based on a questionnaire. Data concerning bladder management and daily consumption of urological appliances for patients with NLUTD in a community setting were collected through a standardized survey. Results Seven hundred and sixty-seven records were analyzed: 543 males, 221 females (N/A = 3). Patients using intermittent catheterization (n= 608) required 5.06 (mean) single-use catheters per day. Out of them, 94 (15.5%) required additional pads (mean: 2.29 per day), 34 patients (5.6%) additionally used pants (mean: 2.55 per day) and 46 patients (7.6%) utilized condom catheters (mean: 3.81 per day) between catheterizations. Among all, 126 patients (16.4%) used pads (mean: 5.03 per day), and 51 patients (6.6%) used pants (mean: 3.03 per day). Women needed both pads (p < 0.0001) and diapers (p = 0.0084) significantly more frequently than men. Eighty-two of the male patients (15.1%) applied condom catheters (mean: 2.8 per day). The target value of the objective daily requirement of incontinence aids for adult patients with NLUTD (based on the upper twofold standard deviation from the mean value) was defined as follows: up to nine single-use catheters, seven condom catheters, nine pads and/or seven pants. A “mixed supply” of different incontinence aids is part of the daily supply for many patients. Conclusion For the first time, these results allow a reasonable regulation of urological aids and appliances based on scientific data for patients with neurogenic bladder.

Abstract
Background: Surgical therapy for benign prostatic obstruction is indicated after failure of medical therapy or in the presence of secondary side effects. Transurethral resection of the prostate (TURP) is the most well-established intervention. Urinary incontinence is the most distressing complication after TURP and may occur secondary to transient stress incontinence, unmasked neurogenic dysfunction, or iatrogenic injury to the external sphincter. Case Presentation: We present a 71-year-old man with total incontinence after TURP from a retained urethral Foley catheter after attempted self-extraction. Conclusion: The transected catheter was removed under general anesthesia with a larger grasper through a rigid cystoscope.

Abstract
Evidence on laparoscopic sacrocolpopexy (LSC) is lacking. Herein, we describe the complications and outcomes of LSC. This single-centre, retrospective cohort study included women with pelvic organ prolapse (POP) who underwent LSC between 2015 and 2017. Preoperative, intraoperative, postoperative, and demographic data were collected. We evaluated patients using the Pelvic Organ Prolapse Quantification system and questionnaires. The primary outcomes were operative characteristics, perioperative complications, early postoperative complications, and anatomical results at 12 months. Forty-six patients (median age: 71 years) underwent LSC. The median follow-up period was 12.0 ± 5.0 (range: 11-26) months. The perioperative complications were bladder perforation and vaginal injury (2.2%). Two (4.3%) patients required reoperation for port-site hernia. One (2.2%) patient developed a retroperitoneal abscess, and one (2.2%) had worsened stress urinary incontinence after LSC. Three (6.5%) patients presented with recurrence of prolapse. LSC is safe and effective for POP.IMPACT STATEMENTWhat is already known on this subject? Laparoscopic sacrocolpopexy (LSC) has become a widely used intervention strategy during the last decade; nevertheless, few studies have reported its outcomes and complications.What do the results of this study add? We demonstrate that LSC for pelvic organ prolapse (POP) has favourable anatomical and voiding functional results, and few perioperative complications. However, it is important to preoperatively inform patients regarding the incidence of mesh-related postoperative complications, although they are not life-threatening, and secure their informed consent.What are the implications of these findings for clinical practice and/or further research? We believe that the LSC procedure, because of its short-term and functional outcomes in the lower urinary tract discussed here, will be more commonly available in clinical practice as a feasible and safe surgical option for POP. However, prospective, large-sample studies should be performed to verify the efficacy of LSC, as further evaluation of the procedure is required.

Abstract
AIMS We compared brain activation patterns between female multiple sclerosis (MS) patients with voiding dysfunction (VD) and those without. We aim to expand current knowledge of supraspinal correlates of voiding initiation within a cohort of female MS patients with and without VD. MATERIALS AND METHODS Twenty-eight ambulatory female MS patients with stable disease and lower urinary tract dysfunction were recruited for this study. Subjects were divided into group 1, without VD (n = 14), and group 2, with VD (n = 14), defined as postvoid residual urine of ≥40% of maximum cystometric capacity or need for self-catheterization. We recorded brain activity via functional magnetic resonance imaging (fMRI) with simultaneous urodynamic testing. Average fMRI activation maps (the Student t test) were created for both groups, and areas of significant activation were identified (P < .05). A priori regions of interest (ROIs), identified by prior meta-analysis to be involved in voiding, were selected. RESULTS Group-averaged blood-oxygen level-dependent (BOLD) activation maps demonstrated significant differences between groups 1 and 2 during initiation of voiding with group 2 showing significantly lower levels of activation in all ROIs except for the left cerebellum and right cingulate gyrus. Interestingly, group 2 displayed negative BOLD signals, while group 1 displayed positive signals in the right and left pontine micturition center, right periaqueductal gray, left thalamus, and left cingulate gyrus. The activation map of group 1 was similar to healthy controls. CONCLUSIONS Our results support the hypothesis that distinct supraspinal activation patterns exist between female MS patients with VD and those without.

Abstract
The authors review urologic dysfunction, including urine retention, incontinence, and recurrent and resistant urinary tract infection, in dogs as a sequela to acute spinal cord injury. Urologic sequelae to acute spinal cord injury (SCI) pose significant complications in human and canine patients impacting quality of life and long-term cost of treatment. Dogs with intervertebral disc extrusion may serve as a natural disease model of acute SCI for investigating translational interventions, both prophylactic and therapeutic, for urologic dysfunction in human SCI patients.

Abstract
Aims Two phase 1 trials were performed in healthy women with the overactive bladder (OAB) syndrome and urodynamically demonstrated detrusor overactivity (DO), with the aim to demonstrate the safety and potential efficacy of URO‐902, which comprises a gene therapy plasmid vector expressing the human big potassium channel α subunit. Methods ION‐02 (intravesical instillation) and ION‐03 (direct injection) were double‐blind, placebo‐controlled, multicenter studies without overlap in enrollment between studies. Active doses were administered and evaluated sequentially (lowest dose first) for safety. ION‐02 participants received either 5000 µg or 10 000 µg URO‐902, or placebo. ION‐03 participants received either 16 000 or 24 000 µg URO‐902, or placebo, injected directly into the bladder wall using cystoscopy. Primary outcome variables were safety parameters occurring subsequent to URO‐902 administration; secondary efficacy variables also were evaluated. Results Among the safety outcomes, there were no dose‐limiting toxicities or significant adverse events (AEs) preventing dose escalation during either trial, and no participants withdrew due to AEs. For efficacy, in ION‐02 (N = 21), involuntary detrusor contractions on urodynamics at 24 weeks in patients receiving URO‐902 (P < .0508 vs placebo) and mean urgency incontinence episodes in the 5000 µg group (P = .0812 vs placebo) each showed a downward trend. In ION‐03 (N = 13), significant reduction versus placebo in urgency episodes (16 000 µg, P = .036; 24 000 µg, P = .046) and number of voids (16 000 µg, −2.16, P = .044; 24 000 µg, −2.73, P = .047) were observed 1 week after injection. Conclusion Promising safety and efficacy results in these preliminary phase 1 studies suggest gene transfer may be a promising therapy for OAB/DO, warranting further investigation.

Abstract
Objectives The aim of this study was to evaluate the frequency and course of post-stroke lower urinary tract dysfunction (LUTD) from early term up to a period of six months and to investigate the relation of LUTD with functional and mental status and quality of life (QoL) in stroke patients. Patients and methods This prospective study included a total of 70 stroke patients (44 males, 26 females; mean age 62.7±7.0 years; range, 46 to 79 years) from five different centers across Turkey between June 2015 and January 2017. The patients were questioned using the Danish Prostatic Symptom Score (DAN-PSS) to evaluate LUTD and evaluated using the Modified Barthel Index (MBI), Incontinence QoL Questionnaire (I-QOL), and Mini-Mental State Examination (MMSE) at one, three, and six months. Results At least one symptom of LUTD was observed in 64 (91.4%), 58 (82.9%), and 56 (80%) of the patients according to the DAN-PSS at one, three, and six months, respectively. A statistically significant improvement was found in the DAN-PSS, MBI, MMSE, I-QOL total scores, avoidance and psychosocial subgroup scores at six months compared to the first month scores (p<0.05). There was a significant negative correlation between the DAN-PSS symptom score at one month and the MBI, MMSE, and QoL scores at six months. The DAN-PSS bother and total scores were found to be significantly and negatively correlated only with the subscales of the QoL questionnaire. Conclusion Based on our study results, LUTD was very common and the prevalence of LUTD findings decreased constantly during six-month follow-up, showing an association with a poor cognitive and functional status and QoL in stroke patients with LUTD.

Abstract
Some patients continue to have obstructive symptoms and/or incontinence after pullthrough surgery for Hirschsprung disease. Incontinence can be due to injury to the anal sphincter and/or dentate line, abnormal colonic motility (nonretentive), or a chronic large stool burden (retentive). A diagnostic algorithm based on clinical and pathological evaluations can be applied to distinguish potential etiologies for obstructive symptoms, which segregate into anatomic (mechanical or histopathological) or physiologic subgroups. Valuable clinical information may be obtained by anorectal examination under anesthesia, radiographic studies, and anorectal or colonic manometry. In addition, histopathological review of a patient's original resection specimen(s) as well as postoperative biopsies of the neorectum usually are an important component of the diagnostic workup. Goals for the surgical pathologist are to exclude incomplete resection of the aganglionic segment or transition zone and to identify other neuromuscular pathology that might explain the patient's dysmotility. Diagnoses established from a combination of clinical and pathological data dramatically alter management strategies. In rare instances, reoperative pullthrough surgery is required, in which case the pathologist must be aware of histopathological features specific to redo pullthrough resection specimens.

Abstract
Diabetic bladder dysfunction is a frequent complication of diabetes. Although many mouse models of diabetes now exist, there has been little systematic effort to characterize them for the timing of onset and severity of bladder dysfunction. We monitored metabolic status and tested bladder function by void spot assay and limited anesthetized cystometry in both male and female mice of three models of obesity and diabetes: a type 1 diabetes model (the Akita mouse) and two type 2 diabetes models [the diet-induced obese (DIO) model and the ob/ob mouse]. Akita mice had insulin pellets implanted subcutaneously every 3 mo to mimic poorly controlled type 1 diabetes in humans. Mice were hyperglycemic by 48 days after implants. Female mice exhibited no bladder dysfunction at any age up to 20 mo and gained weight normally. In contrast, by 7 mo, male Akita mice developed a profound polyuria and failed to show normal weight gain. There were no observable signs of bladder dysfunction in either sex. DIO mice on high/low-fat diets for 16 mo exhibited mild hyperglycemia in female mice (not in male mice), mild weight gain, and no evidence of bladder dysfunction. Ob/ob mice were followed for 8 mo and became extremely obese. Male and female mice were glucose intolerant, insulin intolerant, and hyperinsulinemic at 4 mo. By 8 mo, their metabolic status had improved but was still abnormal. Urine volume increased in male mice but not in female mice. Bladder dysfunction was observed in the spotting patterns of female mice at 4 and 6 mo of age, resolving by 8 mo. We conclude there are dramatic sex-related differences in lower urinary tract function in these models. Male Akita mice may be a good model for polyuria-related bladder remodeling, whereas female ob/ob mice may better mimic storage problems related to loss of outlet control in a setting of type 2 diabetes complicated by obesity.

Abstract
Mesh was a promising, minimally invasive, and 'gold standard' treatment for urinary stress incontinence. Time has shown that complications from these devices can happen early, or even several years, after mesh placement and can be catastrophic. Pain, erosion, voiding dysfunction, infection, recurrent UTIs [urinary tract infections (UTIs)], fistulae, organ perforation, bleeding, vaginal scarring, neuromuscular alterations, LUTS (lower urinary tract symptoms), bowel complications and even immune disorders have been linked to mesh. Various tools, such as imaging, endoscopic and functional studies, are available for diagnosis of mesh complications. Since the spectrum of complications is wide, involvement of other specialties is usually beneficial in the diagnosis and management of these complications. There is still much to learn on the accuracy and utility of diagnostic studies in each type of complication. Evidence on the best diagnostic and treatment pathways for these complications is scarce but continuously growing as information is being reported, and we continue to gain expertise in dealing with patients affected by mesh. Treatment options include conservative and medical management initially and then open or minimally invasive surgical procedure approaches. This article will describe diagnostic and treatment pathways for mesh complications.

Yamashiro J, de Riese W, de Riese C. New Implantable Tibial Nerve Stimulation Devices: Review of Published Clinical Results in Comparison to Established Neuromodulation Devices. Res Rep Urol 2019; 11:351-357. [PMID: 31921712 PMCID: PMC6934123 DOI: 10.2147/rru.s231954] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Accepted: 11/26/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose The purpose of this review is to offer an update for medical providers practicing general urology and urogynecology in evolving and new promising technologies for neuromodulation in patients with OAB. Patients and Methods A focused literature search for the years 2015 through 2019 was conducted on PubMed/Medline for the terms: “new techniques” AND “neuromodulation” AND “tibial nerve stimulation” AND “overactive bladder”. We limited our search to publications in English, for the last five years and with patient follow-up of at least 3 months. Results Clinical success, safety based on adverse events, and quality of life improvement criteria were evaluated and compared to sacral nerve stimulation (SNS) devices and older, non-implantable percutaneous tibial nerve stimulation (PTNS) treatment devices. Considering the limited number of participants with up to 6 months follow-up data currently available, overall the clinical response rates suggest that the new implantable devices stimulating the tibial nerve have a promising clinical outlook, are less invasive upon implantation than SNS, less expensive, and less of a burden on patients compared to the older non-implantable PTNS devices. Conclusion Practicing urologists should be aware of this new treatment option when counseling their patients regarding treatment for OAB.

Abstract
AIM To translate the International Consultation on Incontinence Questionnaire (ICIQ) Long-Term Catheter Quality of Life (LTCqol) questionnaire (ICIQ-LTCqol) from English to Arabic and evaluate its psychometric properties. BACKGROUND Currently, no tool for Arabic-speaking patients is available to measure the quality of life in patients using long-term urinary catheters. DESIGN Translation and psychometric assessment of questionnaire. METHODS The internal consistency and construct validity of the translated Arabic version of the ICIQ-LTCqol were evaluated in a convenience sample of 141 participants recruited from a hospital in Egypt from April to September 2017. Test-retest reliability was assessed for a sample of 15 participants who completed this version at two time points. Construct validity was assessed by factor analysis. RESULTS The translated Arabic version of the ICIQ-LTCqol showed satisfactory test-retest reliability and internal consistency, with the Cronbach α = .75. Confirmatory factor analysis confirmed the same two factors ("catheter function" and "lifestyle") structure as found in the English version of the tool supporting the construct validity of the translated questionnaire. CONCLUSION This original and significant study allows, for the first time, researchers and clinicians working with Arabic-speaking patients, the opportunity to evaluate the quality of life in long-term urinary catheter users.

Abstract
Urgency, defined as "a sudden, compelling desire to pass urine which is difficult to defer", is not always reported by patients with overactive bladder, and is not usually described in these words. Urgency is known to have a strong negative impact on patients' quality of life and requires attention from healthcare professionals, as they play a key role in establishing the diagnosis and in deciding, together with the patient, the most appropriate treatment. This topic was debated during the symposium "Urinary Urgency: A Symptom in Need of a Cure?", held at the 11th Annual Meeting of the European Urogynaecology Association (EUGA) in October 2018 in Milan, Italy. The presentation of two clinical cases, those of a young, active woman and a retired teacher, illustrated the importance of this cornerstone symptom and demonstrated how fesoterodine may represent an important option in the management of this condition. The experts concluded that the physician should not leave urgency undeclared or untreated; that the patient should be involved in the choice of treatment; and that fesoterodine, which offers flexible dosing and has proven, consistent positive results on urgency episodes and urgency urinary incontinence, with very low/no risk of impairment of cognitive function, appears to be one of the good choices in the treatment of this symptom.

Abstract
Objectives To assess and compare the effect of transcutaneous Dorsal Genital Nerve Stimulation (DGNS), Tibial Nerve Stimulation (TNS), Sacral Nerve Stimulation (SNS), and Spinal Stimulation (SS) on Neurogenic Detrusor Overactivity (NDO) and bladder capacity in people with Spinal Cord Injuries (SCI). Materials and Methods Seven male participants with supra-sacral SCI were tested. Standard cystometry (CMG) was performed to assess bladder activity at baseline and with stimulation applied at each site. This was conducted over four separate sessions. All stimulation was monophasic, 15 Hz, 200 μS pulses and applied at maximum tolerable amplitude. Results were analysed against individual control results from within the same session. Results Dorsal Genital Nerve Stimulation increased bladder capacity by 153 ± 146 ml (p = 0.016) or 117 ± 201%. DGNS, TNS and SNS all increased the volume held following the first reflex contraction, by 161 ± 175, 46 ± 62, and 34 ± 33 ml (p = 0.016, p = 0.031, p = 0.016), respectively. SS results showed small reduction of 33 ± 26 ml (p = 0.063) from baseline bladder capacity in five participants. Maximum Detrusor Pressure before leakage was increased during TNS, by 10 ± 13 cmH2O (p = 0.031) but was unchanged during stimulation of other sites. DGNS only was able to suppress at least one detrusor contraction in five participants and reduced first peak detrusor pressure below 40 cmH2O in these 5. Continuous TNS, SNS, and SS produced non-significant changes in bladder capacity from baseline, comparable to conditional stimulation. Increase in bladder capacity correlated with stimulation amplitude for DGNS but not TNS, SNS or SS. Conclusion In this pilot study DGNS acutely suppressed detrusor contractions and increased bladder capacity whereas TNS, SNS, and SS did not. This is the first within individual comparison of surface stimulation sites for management of NDO in SCI individuals.

Abstract
The function of the lower urinary tract is mainly storage and voiding of urine, which is coordinated by the nervous system. Various diseases of the nervous system may cause neuro-urological symptoms. Neuro-urological symptoms depend on the localization of the disease and the extension of the neurological lesion. About 80% of multiple sclerosis (MS) patients have neuro-urological symptoms within 10 years after diagnosis. In addition, 10% of MS patients may even present with voiding dysfunction at disease onset. In this review, different types of neuromodulation are discussed. The available studies suggest that sacral neuromodulation (SNM) and percutaneous tibial nerve stimulation (PTNS) may be helpful in the neuromodulation of MS-related overactive bladder symptoms. These techniques may not only decrease the severity of symptoms but also significantly improve the quality of life of affected patients. Exploring the role of implantable tibial nerve stimulation devices in patients with MS could open new doors in the management of urgency and urgency incontinence in this patient group.

Abstract
Introduction: Due to the high prevalence of anal fistulas and the recurrence of the disease following surgery, different methods have been suggested for appropriate treatment of this disease. In this study, the effects of rectal advancement flap surgery and seton placement on the recurrence rate, incontinence and wound infection were compared. Methods: In this interventional, prospective and quasi-experimental study, 45 patients with anal fistulas including 28 males and 17 females were studied for 2 years (2015-2017). Patients were divided into two groups and mucosal advancement flap and seton placement techniques were used for each of them. Descriptive analysis of data was performed by SPSS software. Results: 24 patients (54%) had seton placement surgery and 21 patients (46%) underwent rectal advancement flap surgery. Recurrence was significantly higher in patients who underwent seton placement surgery than the group that underwent rectal advancement flap surgery. Twelve patients (57%) who underwent rectal advancement flap surgery showed improvement in sphincter tone while 11 patients (45%) showed improvements with seton placement. Conclusion: The overall results of this study showed that rectal advancement flap surgery reduces recurrence and wound infection more significantly than seton placement in patients with anal fistula.

Abstract
Objectives: Third line treatment of urge urinary incontinence (UUI) and/or reduced bladder capacity is bladder augmentation. The aim of this study was to investigate whether clam enterocystoplasty (CECP) was an efficient treatment for patients who were refractory to conservative treatments of UUI and small functional bladder capacity and secondly if there was a difference in outcome in patients with neurogenic and non-neurogenic bladders.Methods: We evaluated 118 patients retrospectively treated in the period 2006-2018 at a single university hospital. Data were collected retrospectively. Patient groups were compared with Wilcoxon signed-rank test and Fisher's exact test.Results: Overall, 76% became continent with 92% using clean intermittent self-catherization (CISC) of patients with neurogenic bladder, 82% became continent and 100% were using CISC, whereas of patients with non-neurogenic bladder 64% became continence and 77% were using CISC. The median overall improvement of capacity was 296.5 mL (IQR: 142-440), 310 mL (186-467) in the neurogenic group and 214 mL (IQR: 126.8-361.5) in non-neurogenic (p = 0.01).Conclusion: CECP is an efficient treatment in UUI and reduced bladder capacity. Difference in outcome was seen with neurogenic patients having a bigger functional capacity and a higher rate of continence compared to the non-neurogenic.

Abstract
OBJECTIVES To consider the provision of post-radical prostatectomy (RP) continence surgery in England. MATERIALS AND METHODS Patients with an Office of Population Census and Surveys Classification of Interventions and Procedures, version 4 code for an artificial urinary sphincter (AUS) or male sling between 1 January 2010 and 31 March 2018 were searched for within the Hospital Episode Statistics (HES) dataset. Those without previous RP were excluded. Multivariable logistic regressions for repeat AUS and sling procedures were built in stata. Further descriptive analysis of provision of procedures was performed. RESULTS A total of 1414 patients had received index AUS, 10.3% of whom had undergone prior radiotherapy; their median follow-up was 3.55 years. The sling cohort contained 816 patients; 6.7% of these had received prior radiotherapy and the median follow-up was 3.23 years. Whilst the number of AUS devices implanted had increased each year, male slings peaked in 2014/2015. AUS redo/removal was performed in 11.2% of patients. Patients in low-volume centres were more likely to require redo/removal (odds ratio [OR] 2.23 95% confidence interval [CI] 1.02-4.86; P = 0.045). A total of 12.0% patients with a sling progressed to AUS implantation and 1.3% had a second sling. Patients with previous radiotherapy were more likely to require a second operation (OR 2.03 95% CI 1.01-4.06; P = 0.046). Emergency re-admissions within 30 days of index operation were 3.9% and 3.6% fewer in high-volume centres, for AUS and slings respectively. The median time to initial continence surgery from RP was 2.8 years. Increased time from RP conferred no reduced risk of redo surgery for either procedure. CONCLUSION There is a volume effect for outcomes of AUS procedures, suggesting that they should only be performed in high-volume centres. Given the known impact of incontinence on quality of life, patients should be referred sooner for post-prostatectomy continence surgery.

Abstract
BACKGROUND Metabolic syndrome (MetS) has a negative impact on functional recovery and complications after many surgical procedures. AIM To assess the role of Mets on functional outcomes and complications after radical prostatectomy (RP) for prostate cancer. PATIENTS AND METHODS Complete data were collected from 5758 patients, undergoing RP at a single referral centers in a 10-year period and the presence of MetS before surgery was ascertained in 17.7% of them using a modified version of the IDF-AHA/NHLBI criteria. Outcomes included 1-year continence and potency rates, early (≤90 days) and late (>90 days) complications. RESULTS Postoperative continence (no pads) was significantly less likely in MetS patients (75.4% vs 82.6%, P < .01), despite no difference in preoperative continence. Erections with or without therapy were reached in 55.8% of non-MetS and 41.8% of MetS patients (P < .01), in this case a significant difference in preoperative function was seen. No differences in early and late complications, except for wound infections (5.8% vs 3.9%, P < .01) were observed. CONCLUSIONS In the present study RP was safe from the complications standpoint in MetS patients, but the presence of the syndrome was a significant risk factor for post-RP incontinence and impotence.
