Urodynamic Parameters and Continence Outcomes in Asymptomatic Patients with Ileal Orthotopic Neobladder: A Systematic Review and Metanalysis.

INTRODUCTION: The orthotopic neobladder is the type of urinary diversion (UD) that most closely resembles the original bladder. However, in the literature the urodynamic aspects are scarcely analysed. OBJECTIVE: To provide the first systematic review (SR) on the urodynamic (UDS) outcomes of the ileal orthotopic neobladders (ONB). Continence outcomes are also presented. METHODS: A PubMed, Embase and Cochrane CENTRAL search for peer-reviewed studies on ONB published between January 2001-December 2022 was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. RESULTS AND CONCLUSION: Fifty-nine manuscripts were eligible for inclusion in this SR. A great heterogeneity of data was encountered. Concerning UDS parameters, the pooled mean was 406.2 mL (95% CI: 378.9-433.4 mL) for maximal (entero)cystometric capacity (MCC) and 21.4 cmH2O (95% CI: 17.5-25.4 cmH2O) for Pressure ONB at MCC. Postvoid-residual ranged between 4.9 and 101.6 mL. The 12-mo rates of day and night-time continence were 84.2% (95% CI: 78.7-89.1%) and 61.7% (95% CI: 51.9-71.1%), respectively.Despite data heterogeneity, the ileal ONB seems to guarantee UDS parameters that resemble those of the native bladder. Although acceptable rates of daytime continence are reported the issue of high rates of night-time incontinence remains unsolved. Adequately designed prospective trials adopting standardised postoperative care, terminology and methods of outcome evaluation as well as of conduction of the UDS in the setting of ONB are necessary to obtain homogeneous follow-up data and to establish UDS guidelines for this setting.

Antibiotic prophylaxis in invasive urodynamics, a Delphi consensus of the Italian Society of Urodynamics (SIUD).

INTRODUCTION: Although antibiotic prophylaxis (AB) demonstrated a statistically significant reduction in bacteriuria after invasive urodynamics (UDS), no significant decrease in the incidence of urinary tract infections (UTI) has been confirmed. No absolute recommendations on the use of AB in case of relevant potential risk of UTI have been reported, though some categories of patients at increased infective probability after UDS have been recognized. The aim of this study is to report the experts' consensus on the best practice for the use of AB before UDS in the main categories of patients at potential risk of developing UTI. MATERIALS AND METHODS: A systematic literature review was performed on AB before UDS in males and females. A panel of experts from the Italian Society of Urodynamics, Continence, Neuro-Urology, and Pelvic Floor (SIUD) assessed the review data and decided by a modified Delphi method on 16 statements proposed and discussed by the panel. The cut-off percentage for the consensus was a ≥70% of positive responses to the survey. The study was a Delphi consensus with experts' opinions, not a clinical trial involving directly patients. RESULTS: The panel group was composed of 57 experts in functional urology and UDS, mainly urologists, likewise gynaecologists, physiatrists, infectivologists, pediatric urologists, and nurses. A positive consensus was achieved on 9/16 (56.25%) of the statements, especially on the need for performing AB before UD in patients with neurogenic bladder and immunosuppression. Urine analysis and urine culture before UDS are mandatory, and in the event of their positivity, UDS should be postponed. A consensus was reached on avoiding AB in menopausal status, diabetes, age, gender, bladder outlet obstruction, high postvoid residual, chronic catheterization, previous urological surgery, lack of urological abnormalities, pelvic organ prolapse, and negative urine analysis. CONCLUSIONS: Antibiotic prophylaxis is not recommended for patients without notable risk factors and with a negative urine test due to the potential morbidities that may result from antibiotic administration. However, AB can be used for risk categories such as neurogenic bladder and immunosuppression. The evaluation of urine analysis and urine culture and postponing UDS in cases of positive tests were considered good practices, as well as performing AB in the neurogenic bladder and immunosuppression.

Open questions on lower urinary tract infections: Results of a Delphi consensus study.

BACKGROUND AND OBJECTIVE: This is a Delphi study that aims to explore expert consensus regarding open questions in current literature evidence on lower urinary tract infections (UTIs). This manuscript deals with adults and analyzed the most recent guidelines and meta-analysis on the topic. METHODS: A panel of leading urologists and urogynaecologists participated in a consensus-forming project using a Delphi method to reach consensus on gray zone issues on recurrent lower UTIns (rUTIs), asymptomatic bacteriuria (AB) in pregnant women, and catheter-associated UTIs (CAUTI) in adults. All the panelists were invited to participate the four phases consensus. Consensus was defined as ≥75% agreement. An ordinal scale (0-10) was used. A systematic literature review was analyzed for diagnostic workup and prevention of rUTIs, AB, and CAUTI. RESULTS: In total, 37 experts participated. All panelists participated in the four phases of the consensus process. Consensus was reached if ≥75% of the experts agreed on the proposed topic. Online meetings and a face-to-face consensus meeting was held in Milan in March 2023. Formal consensus was achieved for 12/13 items. CONCLUSIONS: This manuscript is a Delphi survey of experts that showed interest on some debated points on rUTIs, AB in pregnancy, and prevention of CAUTI. There is still little data on nonantibiotic prevention of UTIs and CAUTI; quite old studies have been reported on AB in pregnancy. The emerging problem of antibiotic resistance is relevant and nonantibiotic prophylaxis may play a role in its prevention.

How do we make progress in phenotyping patients with lower urinary tract such as overactive bladder and underactive detrusor, including using urine markers and microbiome data, to personalize therapy? ICI-RS 2023-Part 2.

INTRODUCTION: Overactive bladder (OAB) and underactive bladder (UAB) could be associated with metabolic syndrome, affective disorders, sex hormone deficiency, changes in urinary microbiota, functional gastrointestinal disorders, or autonomic nervous system dysfunction. OBJECTIVES: The aim of this Think Tank was to provide a guide on how to investigate OAB and/or detrusor underactivity (DU) patients to better clarify the underlying pathophysiology and possibly personalize the treatment. METHODS: A compendium of discussion based on the current evidence related to phenotyping patients with OAB or DU using urodynamic tests, functional neuro-imaging, urinary markers, and microbiome. RESULTS AND CONCLUSIONS: The article emphasizes the critical significance of adopting a comprehensive yet tailored approach to phenotyping patients with lower urinary tract (LUT) symptoms, such as OAB and UAB. The intricate interplay between the LUT and various factors, metabolic, neurological, psychological, and gastrointestinal can define unique LUT profiles, enabling personalized therapies to replace the one-size-fits-all approach.

Robot-Assisted Sacrocolpopexy versus Trans-Vaginal Multicompartment Prolapse Repair: Impact on Lower Bowel Tract Function.

BACKGROUND: This study evaluated the effectiveness, safety, and possible changes in bowel symptoms after multicompartment prolapse surgery by comparing two different surgical approaches, transvaginal mesh surgery with levatorplasty (TVMLP) and robot-assisted sacrocolpopexy (RSC). METHODS: All patients underwent pelvic (POP-Q staging system) and rectal examination to evaluate anal sphincter tone in the lithotomy position with the appropriate Valsalva test. The preoperative evaluation included urodynamics and pelvic magnetic resonance defecography. Patient Global Impression of Improvement (PGI-I) at follow-up measured subjective improvement. All patients completed Agachan-Wexner's questionnaire at 0 and 12 months of follow-up to evaluate bowel symptoms. RESULTS: A total of 73 cases were randomized into the RSC group (36 cases) and TVMLP group (37 cases). After surgery, the main POP-Q stage in both groups was stage I (RCS 80.5% vs. TVMLP 82%). There was a significant difference (p < 0.05) in postoperative anal sphincter tone: 35%. The TVMLP group experienced a hypertonic anal sphincter, while none of the RSC group did. Regarding subjective improvement, the median PGI-I was 1 in both groups. At 12 months of follow-up, both groups exhibited a significant improvement in bowel symptoms. CONCLUSIONS: RSC and TVMLP successfully corrected multicompartment POP. RSC showed a greater improvement in the total Agachan-Wexner score and lower bowel symptoms.

Continence-Sparing Techniques in Radical Prostatectomy: A Systematic Review of Randomized Controlled Trials.

Background: Numerous continence-sparing radical prostatectomy techniques have been developed to enhance postoperative early continence (EC) recovery; however, evidence regarding the best approach remains controversial. The objectives are to provide a critical appraisal of various prostatectomy techniques, based on the evidence of quality-assessed randomized control trials (RCTs); to summarize the immediate continence and the EC reported; and to propose a new standardization for continence outcomes reporting. Methods: Data acquired from five medical registries were reported to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Evidence from published, English, full-text RCTs reporting postoperative urinary continence outcomes within 6 months from surgery was included. The heterogeneity of surgical techniques and continence definitions did not allow a meta-analysis. All RCTs were critically appraised, and quality assessed. Results: In total, 39 RCTs were included: 19 of 39 studies were low-quality RCTs, presenting small cohort, monocentric, or single-surgeon data. The best RCT-supported evidence is in favor of robot-assisted radical prostatectomy (RARP) compared with laparoscopic radical prostatectomy (LRP) and of the Retzius-sparing (RS) technique over the traditional prostatectomy. Other techniques such as bladder neck and puboprostatic ligament (PPL) preservation, posterior reconstruction with or without combination of anterior suspension technique, and nerve-sparing (NS) approach seem to enhance EC. Oppositely, the endopelvic fascia preservation, bladder neck mucosa eversion/plication/slings, and the selective ligature of dorsal venous complex (DVC) were not significantly associated with EC improvements. RCTs are lacking on pubovesical complex-sparing, seminal vesicle preservation, anterior reconstruction of the puboprostatic collar, musculofascial reconstruction, and DVC suspension to the periosteum of the pubic bone techniques. Conclusions: RARP and RS have high-quality evidence supporting their ability to enhance postoperative EC recovery. NS, bladder neck, and PPL preservation may contribute to better EC recovery, although the evidence level is low. Further multicenter RCTs are needed to establish the optimal combination of standard surgical techniques. A new continence outcome-reporting standardization was proposed.

How should prospective research be designed to legitimately assess the value of urodynamic studies in female urinary incontinence?

AIMS: Since formal evidence demonstrating the value of urodynamic studies (UDS) in functional urology remains elusive, we aimed to consider how best to design robust research for this purpose in female urinary incontinence. METHODS: An expert group was convened to debate the following considerations: (a) precedents for formally proving the value of a gold standard diagnostic test, (b) key research principles, (c) defining a study population, (d) selecting endpoints, (e) defining interventional and controls arms, (f) blinding, (g) powering the study, and (h) duration of follow-up. In each case, we considered the strengths and weaknesses of different approaches in terms of scientific validity, ethical acceptability, practicality, and likelihood of bias. RESULTS: We agreed that unlike evaluating therapies, attempting to judge the value of a diagnostic test based on eventual treatment success is conceptually flawed. Nonetheless, we explored the design of a hypothetical randomized controlled trial for this purpose, agreeing that: (1) the study population must sufficiently reflect its real-world counterpart; (2) clinical endpoints should include not only continence status but also other lower urinary tract symptoms and risks of management; (3) participants in the interventional arm should receive individualized management based on their UDS findings; (4) the most scientifically valid approach to the control arm-empiric treatment-is ethically problematic; (5) sufficient statistical power is imperative; and (6) ≥ 2 years' follow-up is needed to assess the long-term impact of management. CONCLUSIONS: Although a perfect protocol does not exist, we recommend careful consideration of our observations when reflecting on past studies or planning new prospective research.

Percutaneous tibial nerve stimulation in the treatment of neurogenic detrusor overactivity in multiple sclerosis patients: a historically controlled study.

Background: Percutaneous tibial nerve stimulation (PTNS) is widely used in the treatment of neurogenic detrusor overactivity (NDO) in multiple sclerosis (MS); however, controlled studies are still lacking.Objective:: To assess effectiveness of PTNS in MS patients with NDO unresponsive to pharmacological and behavioural therapies. Methods: MS patients with NDO were enrolled. Inclusion criteria were NDO not responding to pharmacological and behavioural therapies. Exclusion criteria were the presence of relevant comorbidities and urinary tract infections. Patients were evaluated using 3-day bladder diaries and validated questionnaires at baseline, after 4 weeks of educational therapy and after 12 PTNS sessions. The primary outcome measure was the percentage of patients considered responders after the behavioural therapy and after the PTNS in a historical controlled fashion (definition of 'responder' was reduction ⩾50% of urgency episodes). Results: A total of 33 patients (26 women, 7 men) were enrolled. Two patients dropped out for reasons not related to the protocol. Two out of 31 patients (6.5%) and 21/29 (72.4%) were considered responders at visits 1 and 2, respectively. In PTNS responders, a statistically significant improvement in both bladder diary results and standardized questionnaire scores was recorded, compared with that obtained with behavioural therapy alone. No serious adverse events were reported. Conclusion: This historically controlled study suggests that PTNS may be effective in improving NDO in MS patients.

ZNF750: A Novel Prognostic Biomarker in Metastatic Prostate Cancer.

Prostate cancer is the most frequently diagnosed cancer and the fifth leading cause of cancer death among men in 2020. The clinical decision making for prostate cancer patients is based on the stratification of the patients according to both clinical and pathological parameters such as Gleason score and prostate-specific antigen levels. However, these tools still do not adequately predict patient outcome. The aim of this study was to investigate whether ZNF750 could have a role in better stratifying patients, identifying those with a higher risk of metastasis and with the poorest prognosis. The data reported here revealed that ZNF750 protein levels are reduced in human prostate cancer samples, and this reduction is even higher in metastatic samples. Interestingly, nuclear positivity is significantly reduced in patients with metastatic prostate cancer, regardless of both Gleason score and grade group. More importantly, the bioinformatics analysis indicates that ZNF750 expression is positively correlated with better prognosis. Overall, our findings suggest that nuclear expression of ZNF750 may be a reliable prognostic biomarker for metastatic prostate cancer, which lays the foundation for the development of new biological therapies.

External Validation of the "Tor Vergata" 3D Printed Models of the Upper Urinary Tract and Stones for High-Fidelity Simulation of Retrograde Intrarenal Surgery.

Introduction: Novel training modalities are being investigated to overcome the challenges associated with learning retrograde intrarenal surgery (RIRS). Consequently, a series of 3D printed models of the upper urinary tract and stones designed for ex vivo surgical simulation was introduced in 2021. This study aims to provide external validation of the training model and assess its role in the development of surgical skills. Materials and Methods: A mixed cohort of 20 urologists at different levels of expertise participated in a whole-day live simulation event to examine the model and perform a timed simulation of intrarenal navigation, stone relocation, and laser fragmentation. Operative times were recorded and two independent expert endourologists scored the simulations according to a modified "Objective Structured Assessment of Technical Skills" (OSATS) scale. Five novice urologists from the cohort performed three further simulations in a subsequent event to assess improvement in surgical skills. Results: Face validity was demonstrated with a median score of ≥4/5 in each of the 11 items investigated. Content validity was also effectively reached, with 100% positive impressions with regard to the usefulness for the acquisition of surgical skills. Significant differences were observed among operative times stratified per surgeon experience (all p < 0.0050), thus providing construct validity. Median total OSATS score for novices was 14 (range 8, 25) and was found to be significantly different from expected expert performance (p = 0.0010). Repeated simulations by novices led to a progressive reduction of operative times (p = 0.0313) and increase in median total OSATS (p = 0.0625). Conclusion: The 3D printed models of upper urinary tract and synthetic training stones for the high-fidelity simulation of each phase of RIRS were validated by this study. The results encourage the usage of the models in simulation courses and the evaluation of their potential role in standardized training curricula.

The bladder contractility and bladder outlet obstruction indices in children. Results of a global Delphi consensus study.

AIMS: This Delphi study was planned to examine global expert consensus with regard to utility, accuracy, and categorization of Bladder Contractility Index (BCI), Bladder Outlet Obstruction Index (BOOI), and the related evidence. This manuscript deals with children and follows previous manuscripts reporting on adult men and women. METHODS: Eighteen experts were invited to answer the two-round survey including three foundation questions and four survey questions. Consensus was defined as ≥75% agreement. The ordinal scale (0-10) in Round 1 was classified into "strongly agree," "agree," "neutral," "disagree," and "strongly disagree" for the final round. A systematic search for evidence was conducted for therapeutic studies that have examined outcome stratified by the indices in children. RESULTS: Eleven experts participated in the survey with 100% completion. Consensus was not noted with regard to any of the questions. There was a general trend toward disagreement with the utility of the BCI and BOOI in children. Systematic search yielded one publication pertaining the value of the indices in predicting long-term outcome in boys treated for posterior urethral valves. CONCLUSIONS: This global Delphi survey of experts showed a general disinclination to use numerical indices for bladder contractility and bladder outflow obstruction in children. There is very little data on the use of the BCI and BOOI indices in children. The establishment of urodynamic indices in children might help refine the treatment of functional urological disorders in children.

The bladder contractility and bladder outlet obstruction indices in adult women. Results of a global Delphi consensus study.

AIMS: This Delphi study was planned to examine global expert consensus with regard to utility, accuracy, and categorization of the bladder contractility index (BCI), bladder outlet obstruction index (BOOI), and the related evidence. This manuscript deals with adult women and follows a previous manuscript reporting on adult men. METHODS: Twenty-nine experts were invited to answer the two-round survey including three foundation questions and 12 survey questions. Consensus was defined as ≥75% agreement. The ordinal scale (0-10) in round 1 was classified into "strongly agree," "agree," "neutral," "disagree," and "strongly disagree" for the final round. A systematic search for evidence was conducted for therapeutic studies that have examined outcome stratified by the indices in women. RESULTS: Eighteen experts participated in the survey with 100% completion. Consensus was noted with regard to 2 of 12 questions, both in the negative. The experts had a consensus that BOOI was neither accurate nor useful and a similar negative trend was noted with regard to BCI. However, there was support, short of consensus, for the utility on an index of bladder contractility and bladder outflow obstruction. Systematic search yielded eight publications pertaining to stress urinary incontinence (n = 6), pelvic organ prolapse (n = 1), and intra-sphincteric botulinum toxin (n = 1). CONCLUSIONS: Experts had significant concerns with regard to the use of the male BCI and BOOI in adult women despite a general recognition of the need for numerical indices of contractility and obstruction. Systematic search showed a striking lack of evidence in this regard.

The bladder contractility and bladder outlet obstruction indices in adult men: Results of a global Delphi consensus study.

AIMS: This Delphi study was planned to examine global expert consensus with regard to utility, accuracy, and categorization of Bladder Contractility Index (BCI) and Bladder Outlet Obstruction Index (BOOI) and the related evidence. METHODS: Twenty-eight experts were invited to answer the two-round survey including three foundation questions and 15 survey questions. Consensus was defined as ≥75% agreement. The ordinal scale (0-10) in round 1 was classified into "strongly agree," "agree," "neutral," "disagree," and "strongly disagree" for the final round. A systematic search for evidence was conducted for therapeutic studies that have examined outcome stratified by the indices in men. RESULTS: Nineteen experts participated in the survey with 100% completion. Consensus was noted with regard to 6 of 19 questions. Experts strongly agreed with utility of quantifying bladder contractility and bladder outflow obstruction with near unanimity regarding the latter. There was consensus that BCI and BOOI were accurate, that BCI was clinically useful, and for defining severe bladder outflow obstruction as BOOI > 80. Systematic search yielded 69 publications (BCI 45; BOOI 50). Most studies examined the indices as a continuous variable or by standard cutoffs (BCI 100, 150; BOOI 20, 40). CONCLUSION: There is general agreement among experts on need for indices to quantify bladder contractility and bladder outflow obstruction as well as with regard to accuracy and utility of BCI and BOOI indices. Few studies have examined the discriminant power of existing cutoffs or explored new ones. This is an extraordinary knowledge gap in the field of urology.

Update on Italian-validated questionnaires for pelvic floor disorders.

INTRODUCTION: Pelvic floor disorders (PFDs), which include urinary incontinence, pelvic organ prolapse, sexual dysfunction and gastrointestinal disorders, affect over 20% of the adult population. Prevalence may also be underestimated, since a certain portion of patients may be reluctant to talk to physicians about PFDs due to embarrassment. Consequently, there is a need for self-assessed diagnostic tools with the capability to screen population and collect clinical information. Symptom and quality of life (QoL) questionnaires - also identified as patient-reported outcomes (PROs) - have been developed with this purpose. Despite the large number of questionnaires available for the assessment of PFDs and QoL-related issues in the English language, few of them have been validated for the Italian language. The objective of this article is to update the list of Italian-validated PROs for PFDs along with practical information concerning literature references and suggestions on how to obtain every single questionnaire. EVIDENCE ACQUISITION: PubMed/MEDLINE databases and websites were used to update the list of available Italian-validated questionnaires about PFDs. Once identified, the possibility to get a copy of the questionnaire was verified and steps to obtain it are reported in the tables. EVIDENCE SYNTHESIS: Eight additional questionnaires validated into the Italian language, for diagnosis and overall management of common urinary, vaginal, sexual and bowel conditions, were retrieved. The complete list of PFDs PROS is reported in a modular format for consultation. CONCLUSIONS: This format is intended to serve as a tool to promote appropriateness in PROs adoption while investigating PFDs in Italian patients.

Percutaneous Tibial Nerve Stimulation Improves Lower Urinary Tract Dysfunction and Infection Rate in a Kidney Transplant Recipient With Augmentation Cystoplasty: A Case Report and Literature Review.

Almost 20% of patients with congenital posterior urethral valves (PUV) reach end-stage kidney disease requiring kidney transplantation (KT). An augmentation cystoplasty (AC) is performed to treat significant lower urinary tract dysfunction (LUTD) which can persist afterwards due to residual valve bladder and lead to recurrent urinary tract infections (UTIs) and a worse graft survival. Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive second-line neuromodulation therapy approved for the treatment of non-neurogenic LUTD performed in the outpatient setting. Herein, we reported the case of significant improvement of bladder voiding pattern and yearly UTI rates through PTNS in a 32-year-old male KT recipient with a history of congenital PUV and AC. The patient was referred to our institution at the beginning of 2019 for urgency, high post-void residual volume (PVR) and recurrent clinically significant UTIs (3 to 4/y). After assessment, the patient attended once-weekly 30-minute sessions of PTNS for 12 consecutive weeks. A significant improvement of urodynamic and infectious outcomes was observed through 3-day bladder diaries, questionnaires, and laboratory exams during the subsequent 3 years of regular follow-up. The present results might be significant for the prevention of antibiotic resistance and for better graft survival in KT recipients. We successfully treated a patient with AC, implying that the technique may be appliable also in this case. Neuromodulation in KT is still an unexplored field of research, we advocate for prospective assessment of the efficacy of PTNS in these patients, as reproducible results might lead to life-changing improvements.

Randomised Controlled Trials Assessing the Clinical Value of Urodynamic Studies: A Systematic Review and Meta-analysis.

Context: The role of urodynamic studies (UDSs) in the diagnosis of lower urinary tract symptoms (LUTS) is crucial. Although expert statements and guidelines underline their value for clinical decision-making in various clinical settings, the academic debate as to their impact on patient outcomes continues. Objective: To summarise the evidence from all randomised controlled trials assessing the clinical usefulness of UDS in the management of LUTS. Evidence acquisition: For this systematic review, searches were performed without language restrictions in three electronic databases until November 18, 2020. The inclusion criteria were randomised controlled study design and allocation to receive UDS or not prior to any clinical management. Quality assessment was performed by two reviewers independently, using the Cochrane Collaboration's tool for assessing the risk of bias. A random-effect meta-analysis was performed on the uniformly reported outcome parameters. Evidence synthesis: Eight trials were included, and all but two focused on women with pure or predominant stress urinary incontinence (SUI). A meta-analysis of six studies including 942 female patients was possible for treatment success, as defined by the authors (relative risk 1.00, 95% confidence interval: 0.93-1.07), indicating no difference in efficacy when managing women with UDS. Conclusions: Although UDSs are not replaceable in diagnostics, since there is no other equivalent method to find out exactly what the lower urinary tract problem is, there are little data supporting its impact on outcomes. Randomised controlled trials have focussed on a small group of women with uncomplicated SUI and showed no added value, but these findings cannot be extrapolated to the overall patient population with LUTS, warranting further well-designed trials. Patient summary: Despite urodynamics being the gold standard to assess lower urinary tract symptoms (LUTS), as it is the only method that can specify lower urinary tract dysfunction, more studies assessing the clinical usefulness of urodynamic studies (UDSs) in the management of LUTS are needed. UDS investigation is not increasing the probability of success in the treatment of stress urinary incontinence.

Antimuscarinics for neurogenic overactive bladder in multiple sclerosis: real-life data.

Background: Antimuscarinics (AMs) represent the mainstay of treatment for storage lower urinary tract symptoms (LUTS) but few data are available on their impact in multiple sclerosis (MS) patients. Objective: To assess effectiveness and tolerability of AMs in MS patients with neurogenic detrusor overactivity (NDO). Methods: Sixty consecutive outpatients, who started treatment with AMs at one centre, were recruited. The primary endpoint was change in Patient's Perception of Intensity of Urgency Scale (PPIUS) at 6 months; secondary endpoints were post-void residual urine (PVR) and pads used daily. Incidence and severity of adverse events (AEs) were recorded. Results: Significant reduction (p < 0.001) of mean PPIUS and pads use were detected, as well as a significant increase (p < 0.001) of PVR (143 ±â€„42 ml).AEs, recorded in 53% of patients, were frequently multiple and caused suspension of AM in 10% of cases, mainly for xerostomia, which has been the commonest AE (26.6%). Neurological AEs appeared in 11.7% of subjects, mostly with oxybutynin. Worsening/onset of voiding LUTS, reported by 8.3% of MS, resulted to be the unique AE correlated to AM dosage. Conclusion: This study suggests that AMs are effective in MS patients, but their use should be tailored on every patient as even low dosages can be poorly tolerated. AEs, including neurological ones, are common.
