The prevalence of urinary incontinence in women in four European countries

Pelvic Floor Muscle Training Using the Perifit Device for the Treatment of Urinary Incontinence: A Pragmatic Trial Using Real-World Data

Introduction

There is a need for home-based alternatives for women to self-manage urinary incontinence (UI). Using a real-world data approach, the aim of this analysis was to evaluate whether training with the Perifit device was effective in reducing UI symptoms.

Materials and Methods

A total of 6060 women (45 ± 10 years) with UI who purchased the Perifit device, completed a validated symptoms questionnaire before training (T1) and again at one or several predefined timepoints during training: T2, after completing 40-60 games; T3, after 90-120 games; and/or T4, after 280-300 games.

Results

UI symptom score decreased progressively from 8.4 ± 4.8 points at T1; to 6.3 ± 4.7 points, 5.5 ± 4.5 points, and 4.6 ± 4.5 points at T2, T3, and T4, respectively (all p < 0.001). The percentage of respondents reporting objective improvement in UI symptoms increased from 71%, to 79%, to 85% at T2, T3, and T4, respectively. Effect size was medium (T2) to large (T3, T4). Higher symptom score at baseline was associated with higher likelihood of improvement. There was no effect of other characteristics including respondent age, menopausal status, time since childbirth, prolapse, or baseline strength on symptom improvement.

Conclusions

This analysis of responses from over 6000 real-world users suggests that home training with the Perifit may be an effective way to reduce UI symptoms in women of all ages. Given the quality of life, economic, and social burdens of living with UI symptoms, home-based pelvic floor muscle training with the Perifit may be a promising tool to allow women to self-manage UI.

Autologous Fascial Slings for Stress Urinary Incontinence: a 17-year Follow-up of a Randomised Controlled Study

INTRODUCTION AND HYPOTHESIS

Safety concerns with the use of mesh in vaginal surgery have been ongoing. Autologous fascial slings (AFS) avoid foreign body complications. We compared the long-term (17-year) outcomes of two AFS repair methods-the standard sling and short sling (sling-on-string), and assessed durability and patient satisfaction of these for the treatment of stress urinary incontinence (SUI).

METHODS

A total of 107 patients from three urogynaecology units who had participated in a randomised controlled trial assessing standard (n = 52) and short (n = 55) slings were followed up for a median period of 17 years. Primary outcomes were Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) scores to assess the impact on the quality of life and symptom distress. Logistic quantile regression was employed to compare the two methods. Secondary outcomes included long-term complications and patient satisfaction.

RESULTS

Mean scores showed no statistically significant difference between the standard and short slings at the 17-year follow-up relating to IIQ and UDI scores, leakage or urgency (p > 0.05). Improved bladder function was observed at 17 years compared with baseline (standard sling-IIQ scores mean difference [MD] 1.22 [CI: 0.69, 1.74], UDI scores MD 0.83 [CI: 0.70, 0.97]; short sling-IIQ score MD 1.14 [CI: 0.73, 1.54], UDI scores MD 0.54 [CI: 0.40, 0.67]) with age-related deterioration over time. Re-operation rates were low and patient satisfaction rates were high (67.2%) at follow-up.

CONCLUSIONS

Autologous fascial slings are an effective and durable option for management of SUI and the short sling procedure can be recommended owing to plausible surgical advantages.

Self-reported urinary incontinence in women is higher with increased age, lower educational level, lower income, number of comorbidities, and impairment of mental health. Results of a large, population-based, national survey in Portugal

PURPOSE

Urinary incontinence (UI) is a common condition in women. The aim of this study is to analyze women with self-reported UI, focusing on socio-demographic data, health-related conditions and comorbidities, and their impact on healthcare resources.

METHODS

We analyzed data from a population-based survey with a representative sample of Portuguese women aged ≥ 18 years (n = 10,465). Women with self-reported symptoms of UI were distributed according to age, education level, and household income. The comparison of comorbidities and use of healthcare resources between the UI and non-UI groups was adjusted for age, education, and body mass index. We computed weighted prevalence and adjusted prevalence ratios with 95% confidence intervals using Poisson regression.

RESULTS

Female UI prevalence was 9.9%, increasing with age (6.3% for 18- to 39-year-old, 40.8% for 75- to 85-year-old women). The prevalence decreased with education level (36.8% in women with no education, 4.6% in women with more than 12 years of education) and household income (29.8% in the 2nd quintile of income, 9.9% in the 5th quintile). Women with UI had a higher level of comorbidities, especially cardiovascular, respiratory, and mental health disorders. UI was also associated with higher consumption of healthcare resources.

CONCLUSION

UI is highly prevalent among Portuguese women. It increases with age, low education level, and low household income. The use of healthcare resources was higher, possibly related with associated comorbidities. Though obtained in a single European country, these data may be useful to design a comprehensive management of UI in other parts of the western world.

Advances in the natural history of urinary incontinence in adult females

The aim of this review is to summarise the related characteristics of the natural history of female urinary incontinence (UI) using a narrative descriptive approach. PubMed, EMBASE and Web of Science were searched for articles published from 1 January 2010 to 1 January 2020 on the natural history of female UI, which including incidence, persistence, progression, remission, and regression of a single subtype of UI and the mutual influence of different UI subtypes. This literature review includes 15 articles published, indicates that UI is highly dynamic, with symptoms varying according to disease severity and subtype and influenced by multiple factors at different disease stages. Recent studies have increased our understanding of the natural history of UI. Future research should systematically analyse the progression of each subtype of UI and interactions between subtypes to prevent the progression of UI across females life course.

Complications of Synthetic Midurethral Slings: Is There a Relevant Discrepancy Between Observational Data and Clinical Trials?

CONTEXT

The complications of synthetic midurethral slings (MUSs) in women with stress urinary incontinence (SUI) have become a globally debated issue.

OBJECTIVE

To systematically review the short- and long-term complications of mesh slings reported in observational data compared with clinical trial data, to determine whether the complication rates from clinical trials reflects "real-world" observational data.

EVIDENCE ACQUISITION

PubMed and Cochrane Library were searched. Methods as detailed in Preferred Reporting Items for Systematic Reviews and Meta-analyses and Cochrane Handbook for Systematic Reviews of Interventions were followed.

EVIDENCE SYNTHESIS

Thirty registries/databases including 709 335 MUS procedures (1-22 yr of follow-up) were identified. MUS procedures were associated with intraoperative bladder perforation in 0.86-3.6%, urethral perforation in 0-0.1%, vascular injury in 0.04-0.1%, voiding lower urinary tract symptoms (LUTS) in 1.47-3.5%, vaginal exposure in 0.2-1.9%, and reoperation in up to 9% of cases. Forty-three randomised clinical trials were identified, including 6284 women who underwent MUS procedures and 2177 women who underwent other interventions (1-10 yr of follow-up). MUS procedures were associated with urinary tract perforation in 2.58%, vaginal injury in 1.43%, de novo voiding LUTS in 4.37%, de novo storage LUTS in 5.41%, mesh extrusion/exposure (vaginal/urinary tract) in 2.54%, dyspareunia in 2.26%, pain (pelvic/suprapubic/perineal) in 2.83%, and reoperation for complications required in 1.82% of cases. Meta-analyses of the randomised controlled trials revealed that retropubic MUSs were associated with more events of urinary tract perforation (risk ratio [RR] 9.81, 95% confidence interval [CI] 5.05-19.04, high certainty of evidence [COE]) and voiding LUTS (RR 1.57, 95% CI 1.19-2.07, high COE) than transobturator MUSs. MUSs were associated with more events of pain than mini-slings (RR 1.72, 95% CI 1.04-2.87, moderate COE).

CONCLUSIONS

Short- and long-term data on complications of polypropylene mesh used for female SUI are fairly comparable when using outcome data from well-designed clinical trials or from less structured prospective or retrospective registries. Comparisons have to be made with caution since the two systems of data collection are inherently incomparable. This knowledge should be incorporated in the discussion on how to implement polypropylene mesh for female stress incontinence.

PATIENT SUMMARY

In order to know whether mesh tapes used for treating stress incontinence work well and are safe, high-quality information is important. It appears that well-designed clinical studies give similar results to large registration databases. These data should be interpreted with caution in view of the different ways the information was collected. These results will help physicians and patients understand the risks of mesh tapes.

Mobile Application Based Pelvic Floor Muscle Training for Treatment of Stress Urinary Incontinence: An Assessor-Blind, Randomized, Controlled Trial

A first-line treatment for stress urinary incontinence (SUI) is pelvic floor muscle training (PFMT) for at least three months. The key problem is that patients do not understand the importance of these exercises and their effectiveness. Mobile health apps offer new possibilities to increase treatment adherence. This study compared a reduction in SUI, exercise adherence, and quality of life in PFMT with animation vs. standard instruction. A prospective, single-blind, randomized control trial was collected. SUI patients were randomized into the application or control groups confirmed using a one-hour pad test. In the intervention group, the PFMT application was applied via mobile phone (PFMT with animations, recording system, and reminder system). The standard exercise protocol was similar in both groups. Additional follow-up was conducted at 4, 8, and 12 weeks. A total of 51 participants were randomized to the application (n = 26) and control groups (n = 25), respectively. At the 12-week follow-up, there was no significant difference between the two groups in terms of SUI cure rate, SUI severity by pad test, and daily SUI episodes from the bladder diary (p-value of 0.695, 0.472, and 0.338, respectively). The mean PFME adherence in the application group was higher than the control group at 8 weeks (66.3 ± 13.6 vs. 52.7 ± 16.6, p = 0.002) and 12 weeks (59.1 ± 13.9 vs. 37.8 ± 11.0, p = 0.001). The application group reported no difference from the conventional PFMT group in terms of improvements in SUI cure rate, symptom severity, and quality of life effects at 12-week follow-up. However, the improvement evaluated by the mean difference in SUI episodes and quality of life effects (ICIQ-UI SF) reported a better outcome in the mobile app group. The PFMT application has been proven to be an effective tool that improves PFMT adherence.

Comprehensive study of anxiety and depression in females with urinary incontinence

BACKGROUND

Anxiety and depression are commonly seen with urinary incontinence (UI) and its association is strongest for urgency and mixed UI. It affects the quality of life and functional status.

AIMS

To assess the prevalence and severity of anxiety and depression in SUI (Stress urinary incontinence) and UUI/MUI (Urge or mixed urinary incontinence), to assess the severity of SUI and UUI/MUI and its association with anxiety and depression and to identify various factors associated with anxiety and depression.

MATERIALS AND METHODS

An observational study using various tools as history regarding urinary incontinence, history of other prior events which can lead to anxiety or depression, age, educational level, BMI (Body mass index), HADS scale (Hospital anxiety and depression scale) for anxiety and depression and ICIQ-UI-SF score (International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form).

RESULTS

The Prevalence of anxiety and depression in UUI/MUI was higher. More women were overweight (BMI > 25) in the UUI/MUI group. Higher prevalence of anxiety and depression in the very severe urinary incontinence group. No association of the level of education with anxiety and depression in women with urinary incontinence.

CONCLUSION

Anxiety and depression are more in UUI/MUI patients compared to SUI. In obese ladies, UUI is more prevalent compared to SUI. Anxiety and depression are more with increasing severity of incontinence. Anxiety and depression have no association with the educational status of the patients.

Prevalence and severity of functional urinary and anorectal disorders and their impact on quality of life in cystic fibrosis

BACKGROUND

In cystic fibrosis (CF), coughing is associated with a risk of pelvic floor dysfunction. However, data on the prevalence of symptoms (stress urinary incontinence, bladder overactivity, dysuria, and faecal incontinence) are lacking in males and females with CF. The impact of incontinence on adherence to respiratory care has not been studied.

METHODS

We conducted a multicentre study in adults with CF followed in the North-West French CF network. Urinary disorders and their severity were assessed using the Urinary Symptom Profile (USP) self-report questionnaire; the impact of urinary disorders on general quality of life was measured using the SF-Qualiveen questionnaire; faecal incontinence was assessed using the Wexner self-report questionnaire; and the CFQ-R14+ questionnaire was used to assess quality of life. A self-administered questionnaire developed for the study assessed the impact of symptoms on respiratory care.

RESULTS

Of the 178 people with CF included, 34 % reported stress urinary incontinence, with a large female predominance (63.5 % of females vs. 7.5 % of males), 65 % bladder overactivity (including 16 % urge incontinence) and 50 % faecal incontinence, also with a female predominance. Neither urinary nor faecal incontinence were related to the severity of the respiratory impairment (FEV1). Quality of life was particularly affected in women. Stress urinary Incontinence symptoms affected respiratory care in both sexes.

CONCLUSION

The prevalence of functional urinary and faecal disorders was high in adults with CF and impacted on quality of life and respiratory care. Therefore, multidisciplinary teams must have knowledge of symptoms, the diagnostic tools and management strategies to provide specific treatment.

Stress Urinary Incontinence: An Unsolved Clinical Challenge

Stress urinary incontinence is still a frequent problem for women and men, which leads to pronounced impairment of the quality of life and withdrawal from the social environment. Modern diagnostics and therapy improved the situation for individuals affected. But there are still limits, including the correct diagnosis of incontinence and its pathophysiology, as well as the therapeutic algorithms. In most cases, patients are treated with a first-line regimen of drugs, possibly in combination with specific exercises and electrophysiological stimulation. When conservative options are exhausted, minimally invasive surgical therapies are indicated. However, standard surgeries, especially the application of implants, do not pursue any causal therapy. Non-absorbable meshes and ligaments have fallen into disrepute due to complications. In numerous countries, classic techniques such as colposuspension have been revived to avoid implants. Except for tapes in the treatment of stress urinary incontinence in women, the literature on randomized controlled studies is insufficient. This review provides an update on pharmacological and surgical treatment options for stress urinary incontinence; it highlights limitations and formulates wishes for the future from a clinical perspective.

Transurethral injection of autologous muscle precursor cells for treatment of female stress urinary incontinence: a prospective phase I clinical trial

INTRODUCTION AND HYPOTHESIS

The purpose was to investigate the safety and feasibility of transurethral injections of autologous muscle precursor cells (MPCs) into the external urinary sphincter (EUS) to treat stress urinary incontinence (SUI) in female patients.

METHODS

Prospective and randomised phase I clinical trial. Standardised 1-h pad test, International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), urodynamic study, and MRI of the pelvis were performed at baseline and 6 months after treatment. MPCs gained through open muscle biopsy were transported to a GMP facility for processing and cell expansion. The final product was injected into the EUS via a transurethral ultrasound-guided route. Primary outcomes were defined as any adverse events (AEs) during follow-up. Secondary outcomes were functional, questionnaire, and radiological results.

RESULTS

Ten female patients with SUI grades I-II were included in the study and 9 received treatment. Out of 8 AEs, 3 (37.5%) were potentially related to treatment and treated conservatively: 1 urinary tract infection healed with antibiotics treatment, 1 dysuria and 1 discomfort at biopsy site. Functional urethral length under stress was 25 mm at baseline compared with 30 mm at 6 months' follow-up (p=0.009). ICIQ-UI-SF scores improved from 7 points at baseline to 4 points at follow-up (p=0.035). MRI of the pelvis revealed no evidence of tumour or necrosis, whereas the diameter of the EUS muscle increased from 1.8 mm at baseline to 1.9 mm at follow-up (p=0.009).

CONCLUSION

Transurethral injections of autologous MPCs into the EUS for treatment of SUI in female patients can be regarded as safe and feasible. Only a minimal number of expected and easily treatable AEs were documented.

Impact of COVID-19 on surgical procedures for stress urinary incontinence in the Brazilian public health system

INTRODUCTION AND HYPOTHESIS

The objective was to characterize the impact of the COVID-19 pandemic on the surgical treatment of female stress urinary incontinence (FSUI) in Brazil.

METHODS

This study was conducted with population-based data from the Brazilian public health system database. We obtained data on the number of surgical procedures for FSUI in 2019 (before the coronavirus disease [COVID-19] pandemic), 2020, and 2021 (during the pandemic) in each of the 27 Brazilian states. We included official Brazilian Institute of Geography and Statistics (IBGE) data on the population, Human Development Index (HDI), and annual per capita income of each state.

RESULTS

A total of 6,718 surgical procedures for FSUI were performed in the Brazilian public health system in 2019. The number of procedures was reduced by 56.2% in 2020, and an additional reduction of 7.2% was seen in 2021. The distribution of procedures by state showed important differences, ranging from 4.4 procedures/1,000,000 inhabitants in Paraíba and Sergipe to 67.6 procedures/1,000,000 inhabitants in Paraná (p<0.01) in 2019. The number of surgical procedures was higher in states with a higher HDI (p=0.0001) and per capita income (p=0.042). The decrease in the number of surgical procedures affected the whole country and its rate did not correlate with HDI (p=0.289) or per capita income (p=0.598).

CONCLUSION

The impact of the COVID-19 pandemic on the surgical treatment of FSUI in Brazil was significant in 2020 and persisted in 2021. Access to surgical treatment of FSUI varied according to geographic region, HDI, and per capita income, even before COVID-19.

Significance of 4D US parameters for the clinical treatment of female patients with stress urinary incontinence

Background

Stress urinary incontinence (SUI) that has been associated with abnormal pelvic floor muscle function or morphology is a common condition. This research aimed to study the impact of the four-dimensional (4D) pelvic floor ultrasound on the treatment of female patients with clinical diagnosis of SUI and to evaluate its clinical significance on SUI.

Methods

We enrolled 51 women with SUI. Before transobturator suburethral tape procedures, the patients underwent 4D pelvic floor ultrasonography. The measurements include residual urine volume, bladder detrusor thickness in resting state, the vertical distance from the bladder neck to the posterior inferior edge of pubic symphysis at rest and Valsalva movement, posterior angle of bladder urethra, and urethral rotation angle. The degree of movement of the bladder neck (the difference between the vertical distance from the bladder neck to the posterior inferior edge of the pubic symphysis under the resting state and the maximum Valsalva movement) and the formation of a funnel at the internal orifice of the urethra were calculated.

Results

The mean bladder detrusor thickness was 2.6 ± 0.9 mm, the vertical distance from the bladder neck to the posterior inferior edge of pubic symphysis was 27.7 ± 4.5 mm, the posterior angle of the bladder was 122.7 ± 18.9°, the vertical distance from the rectal ampulla to the posterior inferior edge of pubic symphysis was 18.5 ± 4.6 mm, and the mean area of hiatus of the levator ani muscle was 22.1 ± 6.0 cm2. The mean posterior angle of the bladder on Valsalva was 159.3 ± 23.1°, and the mean urethral rotation angle was 67.2 ± 21.4°.

Conclusions

The 4D pelvic floor ultrasound is a reliable method in evaluating preoperational morphological characteristics of patients with SUI. With the help of the 4D pelvic floor ultrasound, the individualized treatment regimen can be developed and, more importantly, the inappropriate surgical decision can be avoided.

The Role of Gene Expression in Stress Urinary Incontinence: An Integrative Review of Evidence

Stress urinary incontinence (SUI) is defined as unintentional urine leakage occurring as a consequence of increased intraabdominal pressure due to absent or weak musculus detrusor contractility. It affects postmenopausal women more often than premenopausal and is associated with quality of life (QoL) deterioration. The complex SUI etiology is generally perceived as multifactorial; however, the overall impact of environmental and genetic influences is deficiently understood. In this research report, we have disclosed the upregulation of 15 genes and the downregulation of 2 genes in the genetic etiology of SUI according to the accessible scientific literature. The analytical methods used for the analysis of gene expression in the studies investigated were immunohistochemistry, immunofluorescence staining, PCR, and Western blot. In order to facilitate the interpretation of the results, we have used GeneMania, a potent software which describes genetic expression, co-expression, co-localization, and protein domain similarity. The importance of this review on the genetic pathophysiology of SUI lies in determining susceptibility for targeted genetic therapy, detecting clinical biomarkers, and other possible therapeutic advances. The prevention of SUI with the timely recognition of genetic factors may be important for avoiding invasive operative urogynecological methods.

Does the climacteric influence the prevalence, incidence and type of urinary incontinence?

Divergent opinions have been reported in the literature regarding the influence of the climacteric on the prevalence, incidence and types of urinary incontinence. In addition, the influence of hormonal therapy in the climacteric (HRT) on the occurrence of urinary incontinence in the perimenopausal period has been the subject of much discussion. This review evaluates the current literature regarding any possible association between the climacteric and the prevalence, incidence and types of urinary incontinence as well as illustrating the possible influence of HRT on urinary incontinence. Urinary incontinence is more common in women than in men and there is evidence to suggest that the prevalence of urinary incontinence in women increases in a linear fashion with age. There is no conclusive evidence to support a specific increase in the prevalence of urinary incontinence at the time of the menopause. Stress urinary incontinence is more common in premenopausal women and urgency urinary incontinence and mixed incontinence are more common in postmenopausal women. Women receiving systemic estrogen, with or without progestogen, are more likely to develop or experience worsening of incontinence.

Effects of Age and Multiple Vaginal Births on Lower Urinary Tract Structure and Function in Nonhuman Primates

Purpose: The relative roles of urinary sphincter damage, aging, and childbirth in stress urinary incontinence (SUI), have not been established. This study was performed to elucidate the roles of these factors.Methods: The study included: (1) 8 female cynomolgus monkeys (17–19 years of age and 7–8 vaginal births each); (2) six 5-yearold nulliparous monkeys with surgically created chronic urinary sphincter dysfunction; and (3) six 5-year-old, nulliparous, nosurgery controls. Sedated abdominal leak point pressure (ALPP) and maximum urethral sphincter pressures (MUP) were measured. Sphincters, bladders, and pelvic support muscles were quantified for collagen content. Additionally, bladders were analyzed for collagen fiber thickness, length, and angle using CT-FIRE analysis of Picrosirius red-stained tissues.Results: Resting MUP values were similar in the controls and older multiparous monkeys (P>0.05). However, aging and multiple births reduced pudendal nerve-stimulated increases in MUP (P<0.05 vs. controls). ALPP values were lower in the older multiparous versus younger groups of monkeys (P<0.05). Sphincter collagen content was greater, and muscle content less, in the injury model (P<0.05 vs. controls). However, these measures were not affected by age and childbirth (P>0.05 vs. young groups). Bladder collagen content was greater, and muscle content less, in the old multiparous monkeys (P<0.05 vs. younger groups). Additionally, collagen fibers were thicker and more angular in the bladders of the older multiparous monkeys than in the other nonhuman primate groups (P<0.05). Pelvic support muscles had higher collagen and lower muscle content in the older multiparous monkeys than in the younger groups of monkeys (P<0.05).Conclusions: SUI, associated with aging and multiple childbirths, appeared to be more strongly associated with bladder dysfunction, reduced pelvic muscle support, and the compensatory response to neural stimulation than with selective urinary sphincter dysfunction.

Long-Term Improvement in Urinary Incontinence in an Elite Female Athlete Through the Laser Treatment: A Case Report

Stress urinary incontinence (SUI) is increasing in elite female athletes (EFAs), affecting competition results and quality of life. Pelvic floor muscle training (PFMT) is the first-line treatment for SUI, and surgery is generally performed when PFMT is insufficient. However, in EFA, there are few cases in which surgery is performed and fewer reports. Therefore, there is no known general treatment strategy for EFA with SUI. In our study, a 23-year-old track-and-field medalist with severe SUI was successfully treated with a vaginal and urethral erbium-doped yttrium aluminum garnet laser (VEL + UEL). After 12 treatments over one year, urinary incontinence decreased from 300 mL or more in the 400 m track run before treatment to 0 mL. She did not experience any more problems during running or competition. There was no recurrence of SUI for three years, and the urethral pressure profile examination confirmed improvement. MRIs showed that the left puborectalis muscle was absent from the first visit. The urethra was oval with an anteroposterior outer diameter of 10 mm and a transverse outer diameter of 13 mm before treatment. However, after three years of treatment, both anteroposterior and transverse diameters became circular, measuring 11 mm. Vaginal wall thickness increased from 8 to 12 mm at the center of the height of the urethra, making it possible to support the urethra, and pretreated adipose tissue space between the urethra and vagina disappeared. It was noted that the uneven and fragile urethra/vagina, the presence of adipose tissue space, and the absence of the left puborectalis muscle may have been the cause of the SUI. One year of VEL + UEL treatment resulted in long-term improvement of SUI; MRI showed changes in the urethra and vagina.

Does the Polydimethylsiloxane Urethral Injection (Macroplastique®) Improve Sexual Function in Women, in Fertile Age, Affected by Stress Urinary Incontinence?

Background and Objectives: Stress urinary incontinence (SUI) negatively affects women’s quality of life, including sexual function. The aim of the current study was to evaluate the effect of polydimethylsiloxane (Macroplastique®) on sexual function in women of fertile age affected by SUI. Materials and Methods: Single-center prospective study. Sexually active women of fertile age with symptoms of pure SUI, which were urodynamically proven, were submitted to intraurethral Macroplastique® injection. At 6-months follow-up, their sexual function was evaluated with Female Sexual Function Index (FSFI), while the SUI cure rate was objectively assessed through a negative stress test and subjectively by a Patient Global Impression of Improvement (PGI-I) score < 3. The difference of coital incontinence prevalence was assessed between the baseline and the 6-month follow-up. Peri- and postoperative complications of Macroplastique® injection were recorded and classified according to the Clavien–Dindo system. Results: Twenty-one women fulfilled inclusion criteria and were submitted to Macroplastique® procedure. The concerning sexual function, desire, satisfaction, and overall FSFI score significantly improved. Since other domains were less impaired at the baseline, we could not assess significant improvement for all of them. We observed a complete regression of coital incontinence (0/21, 0%) in comparison with the baseline (5/21, 23.8%; p = 0.04). The objective SUI cure rate was 76% (16/21), while the subjective SUI cure rate was 80.9% (17/21). One woman developed de novo overactive bladder, and two women developed postoperative voiding dysfunction (self-solved in 24 h). Conclusions: The Macroplastique® urethral injection was demonstrated to be safe and effective in improving sexual function in sexually active women of fertile age affected by pure SUI, urodinamically proven at 6-months follow-up.

Nine years follow-up after TVT-O; the mesh still available for women suffering from urinary incontinence

OBJECTIVE

The efficacy of TVT-O is well established in patients with stress urinary incontinence (SUI). The objective of this study was to evaluate the efficacy, safety and patient satisfaction of TVT-O in patients suffering from primary or recurrent SUI or mixed urinary incontinence (MUI).

METHODS

A single-center follow-up study was conducted. All consecutive women treated by TVT-O between August 2004 and October 2011 were included. Objective treatment success was a negative stress test. Patient satisfaction was assessed by questionnaires.

RESULTS

The mean time from the surgery to the last follow-up visit was 9 years. One hundred and six patients were included in the final evaluation. Nineteen patients (18%) were previously operated on for urinary incontinence (UI). Ninety patients (85%) were objectively cured; 68 (89%) of the SUI and 22 (73%) of the MUI patients (p = 0.067). Fourteen (74%) of the previously operated patients and 76 (87%) of the patients who underwent first-time TVT-O were objectively cured (p = 0.158). Eighty-six patients (81%) achieved subjective success; 70 (92%) of the SUI and sixteen (53%) of the MUI patients (p<0.001). Eleven women (58%) who had repeat surgery and 75 women (86%) who had primary operation were subjectively cured (p = 0.008).

CONCLUSIONS

TVT-O is effective in women who suffer from SUI having 90% objective and subjective cure rate 9 years after surgery. There were no major complications, but 16% of the women suffered from groin pain and 37% had urgency symptoms. The results of TVT-O were still good, and it is a therapeutic alternative for different subgroups of UI including recurrent cases.

Single center experience and long-term outcomes of implantable devices ACT and Pro-ACT (Uromedica, Irvin, CA, USA) - Adjustable continence Therapy for treatment of stress urinary incontinence

PURPOSE

In this study, we aimed at evaluating the long-term adjustable peri-urethral balloons (PUB) durability in both male and female with neurogenic or non-neurogenic stress urinary incontinence.

MATERIAL AND METHODS

Each consecutive patient who underwent surgery for PUB placement before 2008 was included in this study. A PUB was proposed for patients with refractory to perineal reeducation stress urinary incontinence (SUI) caused by intrinsic sphincter deficiency. There were no exclusion criteria. Demographic, clinical and perioperative data were collected retrospectively from our clinical follow-up notes.

RESULTS

A total of 177 patients were included in the study. Median [IQR] follow-up was 5 years [1.8-11.2]. The 3 main causes of SUI were radical prostatectomy (n=82, 46.3%), idiopathic intrinsic sphincter deficiency (n=55, 31.1%) and neurogenic sphincter deficiency (n=32, 18.1%). Complete continence (no pad necessary) was achieved for 109 patients (61.6%). At the end of the follow-up, the PUB global survival rate was 47.5% (Fig. 1). Median [IQR] PUB survival without removal was 57.8 months [42.3-81.7]. PUB survival without failure rate was 68.4% accounting for a median [IQR] survival duration of 116.9 months [86.2-176.9] CONCLUSION: In this study, we evidenced acceptable long-term efficiency and survival of PUB in the management of SUI in both neurogenic and non-neurogenic population. Given those results it could be a good alternative to AUS on unfit or unwilling population.

Evaluation of the effectiveness of transobturator tape operation in the treatment of stress incontinence

Abstract Background/Aims:: In this study, In this study, we aimed to assess the effectiveness of Transobturator Tape Operation in the treatment of Stress İncontinence Methods: We retrospectively evaluated 454 patients who had TOT operations due to stress urinary incontinence between January 1, 2017, and December 31, 2020, at the İstanbul Kanuni Traning and Research Hospital. The basic clinical characteristics of the participants were recorded. The number of daily peds, values of Q-type test and urinary retention, and scores of urogenital disorder inventory-6 and impact of incontinence inquiry form at the clinical evaluation perioperatively and 6 months after the operation. Data analysis of the study was done with the SPSS version 24.0 package program. Kolmogorov-Smirnov test was used for normality analysis. Wilcoxon test was used for the comparisons of preop and postop data. It was considered statistically significant when the P value was below 0.05 Results: The study was conducted on 454 patients aged 26-83 years with a mean age of 50.3±10 years. The overall complication rate was 15.9. The rate of those who recovered six months after the operation was 89.6%. The number of daily peds, values of Q-tip test and urinary retention, and scores of questionnaires were significantly reduced after surgery (p=0.001). Conclusions: The TOT operation can be preferred in treating stress incontinence with acceptable success and outcome. The scales of questionnaires successfully determine patient satisfaction with surgical efficacy for SUI.

CO2 laser therapy for management of stress urinary incontinence in women: a systematic review and meta-analysis

Background

Carbon dioxide (CO2) laser therapy is an emerging treatment for women with stress urinary incontinence (SUI).

Objectives

To examine the efficacy of CO2 laser therapy for management of SUI-related symptoms in women.

Design

A systematic review and meta-analysis of randomized controlled trials and cohort studies.

Data sources and methods

Four databases were screened until January 2023. All efficacy continuous endpoints were assessed via subtraction of the posttreatment from pretreatment values. The data were summarized as mean difference (MD) with 95% confidence interval (CI) using the random-effects model.

Results

A total of 15 studies with 700 patients were analyzed. CO2 laser therapy significantly decreased the 1-h pad weights at 3 months [n = 5 studies, MD = -3.656 g, 95% CI (-5.198, -2.113), p < 0.001], 6 months [n = 6 studies, MD = -6.583 g, 95% CI (-11.158, -2.008), p = 0.005], and 12 months [n = 6 studies, MD = -3.726 g, 95% CI (-6.347, -1.106), p = 0.005]. Moreover, CO2 laser therapy significantly decreased the International Consultation of Incontinence Questionnaire-Urinary Incontinence Short Form Scores at 3 months [n = 10 studies, MD = -4.805, 95% CI (-5.985, -3.626), p < 0.001] and 12-months [n = 6 studies, MD = -3.726, 95% CI (-6.347, -1.106), p = 0.005]. Additionally, CO2 laser therapy significantly decreased the Pelvic Floor Impact Questionnaire scores at 6 months [n = 2 studies, MD = -11.268, 95% CI (-18.671, -3.865), p = 0.002] and 12 months [n = 2 studies, MD = -10.624, 95% CI (-18.145, -3.103), p = 0.006]. Besides, CO2 laser therapy significantly decreased the Urogenital Distress Inventory-6 scores at 3 months [n = 2 studies, MD = -21.997, 95% CI (-32.294, -11.699), p < 0.001], but not at 6 months [n = 3 studies, MD = -3.034, 95% CI (-7.357, 1.259), p = 0.169]. Lastly, CO2 laser therapy significantly increased the Vaginal Health Index Score at 6 months [n = 2 studies, MD = 2.826, 95% CI (0.013, 5.638), p = 0.047] and 12 months [MD = 1.553, 95% CI (0.173, 2.934), p = 0.027].

Conclusion

CO2 laser therapy improved the SUI-related symptoms in women. To obtain solid conclusions, future studies should be well-designed with standardized settings, consistent therapeutic protocols, and long-term follow-up periods.

The Transobturator Tape Versus Retropubic Tension-Free Vaginal Tape in the Treatment of Comorbid and Elderly Women With Stress Urinary Incontinence: A Retrospective Analysis of Over 800 Women

Background and objective The first-line surgical treatment for female stress urinary incontinence (SUI) involves midurethral slings (MUS), including the transobturator tape (TOT) and the retropubic tension-free vaginal tape (TVT). However, whether offering these procedures to older and comorbid women could lead to increased complications is a question that needs to be seriously addressed. In this retrospective cohort study, we aimed to compare the two procedures and evaluate the impact of age, BMI, and comorbidities on complications. Materials and methods A total of 873 procedures (306 TVTs/567 TOTs) performed between 2007 and 2017 were compared and correlated with regard to age, BMI, and comorbidities. Intraoperative complications included bleeding >50 ml, bladder injury, and anesthesia-associated complications. Postoperative complications included post-void residual volume, pain, hematoma, lower urinary tract infection, revision for loosening tape, and bladder infections. The comorbidities were evaluated based on the American Society of Anesthesiologists (ASA) and Charlson scores. Results A total of 873 MUS were conducted during the study period: 306 TVTs and 567 TOTs. Groupwise comparison between these procedures showed that women in the TOT group were older (p<0.001) with a higher BMI (p<0.001) and a higher ASA score (p<0.001) compared to the TVT group. Nevertheless, significantly more intraoperative complications, especially bladder injuries, were recorded in the TVT group. Postoperative complications occurred in 19.4% of the entire cohort, especially increased post-void residual volume. Postoperative hematoma and tape loosening were significantly more frequent in the TOT group. Age, BMI, and comorbidities showed no significant impact on intraoperative complications; however, the TOT procedure was associated with significantly fewer intraoperative complications [p=0.001, odds ratio (OR): 0.281]. Conclusions Overall, both procedures were associated with a low number of perioperative complications. The TOT technique had a lower incidence of intraoperative complications. It must be highlighted that age and comorbidities had no influence on either the intra- or postoperative complication rates. Hence, we recommend that TOT is employed to treat SUI in older, more obese, and comorbid women.

Prevalence and sociodemographic correlates of urinary incontinence in Japanese women: A web-based cross-sectional study

BACKGROUND

Epidemiological studies on urinary incontinence that used a validated international standard questionnaire are limited in Japan, and few studies have examined the sociodemographic and behavioral correlates of urinary incontinence.

OBJECTIVE

The aim of this study was to estimate the prevalence of urinary incontinence according to the Japanese version of the International Consultation on Incontinence Questionnaire-Short Form, and its sociodemographic and behavioral correlates among Japanese women.

DESIGN

A web-based cross-sectional study.

METHODS

A randomly sampled cross-sectional Internet survey was conducted in Japan among 3030 women aged 20-64 years. The International Consultation on Incontinence Questionnaire-Short Form score, sociodemographic, body mass index, medical and childbirth history, practice of pelvic floor muscle training, and medical care use were obtained. Descriptive statistics, the chi-square test, and forced-entry logistic regression analysis were used in data analysis.

RESULTS

Participants' average age was 43.4 years, and the response rate was 32.9%. The prevalence of urinary incontinence was 25.5%, and it increased with age. Stress urinary incontinence was the most common subtype (57.4%), followed by urge urinary incontinence (20.3%) and mixed urinary incontinence (16.7%). Less than 5% of those with urinary incontinence had experience with pelvic floor muscle training and medical care use. Middle-aged and older (p < 0.001), overweight and obesity (p < 0.001), vaginal delivery status (p < 0.001), low back pain (p = 0.008), and previous pelvic floor muscle training engagement (p < 0.001) were significantly associated with urinary incontinence.

CONCLUSION

Increasing population awareness of urinary incontinence from an early age and developing effective interventions for the identified at-risk groups, such as the middle-aged and older, those with overweight and obesity, and those with previous pregnancies, are urgently needed.

Impact of a Community-Based Pelvic Floor Kinesic Rehabilitation Program on the Quality of Life of Chilean Adult Women with Urinary Incontinence

The pelvic floor forms the primary bottom tissue of the pelvic cavity. It comprises muscles that play a fundamental role in bowel and bladder emptying. Alterations of pelvic floor muscles will result in dysfunctions such as urinary incontinence (UI). Given the high prevalence of UI and its impact on the quality of life (QoL) in patients with pelvic floor muscle dysfunctions, it is necessary to implement public, community, and generalized programs focused on treating these dysfunctions.

OBJECTIVE

To determine the effect of a community rehabilitation program on QoL, UI severity, and pelvic floor muscle strength in patients with UI.

PATIENTS AND METHOD

A descriptive prospective cohort study. Twenty subjects between 44 and 75 years old with a diagnosis of UI, participants of a community kinesic rehabilitation program on the pelvic floor in Maipú, Santiago, Chile, were evaluated. These volunteers were intervened for six months, and QoL was measured with the 36-Item Short-Form Health Survey (SF-36) and International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) scales, UI severity with the Sandvick test, and pelvic floor muscle strength with the Oxford scale. Patients were followed up three months post-intervention.

RESULTS

Significant improvements were observed in all scales after applying for the community kinesic rehabilitation program, and the changes were maintained at a 3-month follow-up.

CONCLUSIONS

Since the improvement in QoL, UI severity, and pelvic floor muscle strength after the intervention, it is relevant to consider the implementation of community programs aimed at education, screening, and early rehabilitation of these patients.

Is urethral pressure associated with parity and delivery mode?

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence is the most prevalent type of urinary incontinence and childbirth is a risk factor. The aim of this study is to evaluate the association between delivery mode and urethral sphincter function as measured by the maximum urethral pressure (MUP).

METHODS

A retrospective study on women seen in a tertiary urogynaecological center for urodynamic testing between January 2017 to December 2019. Women were classified into the following groups: (1) nulliparous; (2) caesarean section only; (3) at least one spontaneous vaginal delivery but no instrumental deliveries; (4) at least one vacuum delivery but no forceps; (5) at least one forceps delivery.

RESULTS

The complete data sets of 1238 women were analysed; 1112 (90%) were vaginally parous. Mean age was 58 (18-95) years. Mean parity was 2.6 (0-9); 57 (4.6%) were nulliparous, 69 (5.6%) had only been delivered by caesarean section, 762 (61.6%) had at least one spontaneous vaginal delivery but no instrumental deliveries, 41 (3.3%) had at least one vacuum but no forceps delivery, and 309 (25%) had at least one forceps delivery. Mean MUP was 41.8 cmH₂O. There was a significant association between vaginal parity and MUP (P < 0.001). On ANOVA test, delivery mode was significantly associated with MUP. This became nonsignificant on regression analysis, with only age significantly associated with MUP (P < 0.001).

CONCLUSIONS

The effect of childbirth on urethral sphincter function seems to be largely due to the first vaginal birth. We failed to show an effect of instrumental delivery.

How Urinary Incontinence Affects Sexual Activity in Polish Women: Results from a Cross-Sectional Study

Urinary incontinence (UI) in women can cause a number of sexual dysfunctions and reduce their quality of life. Sexual health is essential to the self-esteem, emotional state, and overall quality of life. We aimed to assess the quality of sexual life of women with UI. The study included a group of 145 sexually active women diagnosed with UI. The research was conducted using the diagnostic survey method with authorial and validated questionnaires. As many as 49.1% of the respondents reported a deterioration of sexual relations in comparison with the time before the onset of UI symptoms. According to the FSDS-R results, 83.45% of respondents were dissatisfied with their sex life. The higher the result obtained by respondents in the FSDS-R scale, the lower was their quality of life in the IIQ-7 scale (p ≤ 0.002, R = 0.53). The greatest impact was observed in the domains of emotional health and physical activity. The more incontinence symptoms reported by the respondent in the UDI-6 scale, the worse was her sexual satisfaction in the FSDS-R (p = 0.003, R = 0.39). UI in women contributes to the development of sexual dysfunctions, including decreased interest in sexual life, limited intercourse, and dissatisfaction with sexual life.

The efficacy and complications of retropubic tension‐free vaginal tapes after twenty years: a prospective observational study

OBJECTIVE

Long-term data regarding risks associated with tension-free vaginal tapes (TVT) are sparse, and where available are limited to small numbers. We analyse patient-reported outcomes of TVT after 16-24 years.

DESIGN

Prospective observational study.

SETTING

Single-centre study in a tertiary referral urogynaecology unit.

POPULATION

A cohort of 350 women who had a TVT inserted between 1999 and 2004, in which 96% had urodynamically proven stress incontinence.

METHODS

Postal questionnaire survey using the International Consultation on Incontinence Questionnaire, a visual analogue scale and a yes/no question as to whether they would have the procedure again.

MAIN OUTCOME MEASURES

The primary outcome was cure of stress urinary incontinence, which was assessed using the ICIQ-FLUTS questionnaire. Secondary outcomes included overactive bladder symptoms, pain, sexual dysfunction, and patient satisfaction with the procedure.

RESULTS

A total of 183/350 (52%) responses were received. The median age of women at follow up was 67 years (range 53-93 years) and the median follow up was 20 years (17-24 years). Stress urinary incontinence was denied by 39.3% of women. Urgency was reported by 42.1%. Bladder pain was reported either 'never' or 'occasionally' by 92.3% of women. The median satisfaction rate was 98/100 and 92.4% said they would have the TVT procedure again.

CONCLUSIONS

Tension-free vaginal tape has high levels of satisfaction and cure up to 24 years after placement. Pain was uncommon and its impact on quality of life was low. Symptoms of urgency were prevalent but may be related to age. TVT is an effective treatment for SUI more than 20 years after initial placement.

Laparoscopic and open burch colposuspension for stress urinary incontinence: advantages and disadvantages

OBJECTIVE

Stress urinary incontinence (SUI) causes a significant physical and psychological burden on women. The laparoscopic vaginal suspension (LC), used in the treatment of women with SUI, is known for its advantages such as smaller incisions, short hospital stays, and better aesthetic results. This article throws light upon the advantages and disadvantages of LC and open Burch vaginal (OC) incontinence along with its associated complications.

PATIENTS AND METHODS

Between December 1, 2017 and February 10, 2019, 26 women with SUI with physical, social, and psychological consequences from two hospitals were enrolled in this study. The sample was divided into two equal groups of 13 women each. Data were collected and statistically analyzed. P ≤ 0.05 is statistically significant.

RESULTS

The study showed that the operational time was significantly shorter in the OC method compared to the LC approach (59.2 ± 5.3 min and 91 ± 4.5 min, respectively). Mean blood loss was higher in the OC approach than in the LC approach (152.2 ± 30.3 and 143.3 ± 38.6, respectively). The LC approach has minimal pain and a shorter hospital stay compared to the OC approach. Patients with the LC approach required less analgesia (8.9 ± 1.3 mg vs 2.5 ± 1.8 mg) and less hospital stay (110.3 ± 11.4 h vs 70.2 ± 8.9 h) after surgery. Resumption of normal activity was faster in the LC approach [25.1 ± (12.6) days, 18.9 ± (12.5) days] than in the OC approach. There was no significant difference between the OC and LC approaches in terms of complications.

CONCLUSIONS

Although LC is a superior and less invasive approach than the OC approach in terms of hospital stay, blood loss, pain, and recovery time, the operation time is longer.

The adaptation states of women with urinary incontinence according to the Roy Adaptation Model: A qualitative study

AIMS

This study aimed to explore experiences of women with urinary incontinence (UI) according to the Roy Adaptation Model (RAM).

METHODS

A phenomenological design was used in this study, and its conceptual framework was formed by the RAM. The sample was composed of 12 women with UI. Face-to-face in-depth interviews were conducted according to data collection tools. Semi-structured interviews were recorded in audio-recording device. Thematic approach was used to assess the data.

RESULTS

The average age of the women was 52.77 ± 7.32 years, seven women had menopause, eight had vaginal birth. According to the thematic approach, four main themes emerged: physiological mode, self-esteem mode, role function mode, and interdependence mode and they had difficulties in this regard.

CONCLUSIONS

The results show that women cannot adapt to the problem of incontinence according to the dimensions of RAM. These factors are important to consider when developing strategies to address UI, diagnosis, and treatment.

Use of Magnetic Resonance Imaging in women with suspected complications following insertion of implants for pelvic organ prolapse and stress urinary incontinence surgery

OBJECTIVE

To evaluate the role of Magnetic Resonance Imaging (MRI) in women presenting with suspected implant complications following surgery for pelvic organ prolapse (POP) and stress urinary incontinence (SUI).

STUDY DESIGN

Retrospective single-centre cohort study in a designated tertiary referral centre. All women with vaginally and/or abdominally placed implants for POP or SUI who were referred with suspected mesh complications, and investigated with an MRI scan, between January 2018-October 2020 were included in the study.

RESULTS

97 women were identified over this time-period with a total of 123 implants, a median age of 55 years (Range: 34-79) and an average insertion to presentation time of 84 months (Range: 2-300). 78% (74) had one implant in situ, with the remainder having at least 2 in situ. Transobturator tapes (TVT-O/TOT) were the most common implants [35% (43)]. Chronic Pelvic or abdominal pain was the most common clinical symptom [73.2% (71/112 primary complaints)] with provoked tenderness on examination being the most common clinical finding [27.8% (32/115 clinical findings)]. MRI was more likely to detect abdominally placed implants [100% (all 30)] and Retropubic Tapes [89% (16/18)] when compared to Transvaginal POP implants [87.5% (28/32)] and TVT-O/TOT [67% (29/43)]. MRI identified both cases of Sacrocolpopexy mesh rupture as well as all 11 cases of infection (100%). In 91% (10/11) of these cases, MRI revealed the infection to be more widespread than clinical findings initially suspected. Cohen's Kappa demonstrated excellent correlation between MRI and surgical findings in cases with implant related infection, rupture and normal findings (κ = 1; z = 4.58; p = 0.00000459).

CONCLUSION(S)

MRI can be a useful tool in assessment and management of patients with complications from implants. MRI can detect infection that may be more extensive that is initially clinically apparent in the outpatient setting. Abdominal implants appear to be easier to detect than transvaginal meshes and trans obturator tapes.

The Role of Pessaries in the Treatment of Women With Stress Urinary Incontinence: A Systematic Review and Meta-Analysis

IMPORTANCE

Pessaries are an important conservative therapy for stress urinary incontinence (SUI), but few studies have comprehensively evaluated their utility.

OBJECTIVE

The objective of this study is to evaluate the existing evidence on the efficacy and safety of pessaries for the treatment of SUI.

STUDY DESIGN

We searched for the terms "stress urinary incontinence" and "pessar/y/ies/ium" in PubMed, Embase, and Cinhal on June 10, 2020. Studies that characterized subjective and/or objective data were included. Studies performed in pediatric populations, pregnancy, and use of pessaries not for SUI were excluded. Two reviewers independently screened and assessed data quality and risk of bias according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Ten studies, including 376 patients, were included. In terms of subjective outcomes, 76% of 72 patients reported feeling continent after pessary treatment compared with 0% of 86 patients surveyed before pessary use (P < 0.0001). Both Urinary Distress Inventory and Incontinence Impact Questionnaire scores decreased significantly by 46.7% (n = 155 baseline, n = 139 follow-up; P < 0.0001) and 67.8% (n = 139 baseline, n = 107 follow-up; P < 0.0001), respectively. Significant objective measures associated with pessary use included increased urethral closure pressure (n = 122; g = 0.56; 95% confidence interval [CI], -0.66 to 1.77; P < 0.049) and decreased pad weight (n = 129 baseline; n = 118 follow-up; g = -0.89; 95% CI, -1.986 to 0.19; P = 0.009). Adverse events significantly decreased at greater than 6 months follow-up compared with less than 6 months follow-up, including pain (31.5%, n = 29/92 vs 14.3%, n = 5/35; P = 0.0513) and discomfort (50%, n = 46/92 vs 29.3%, n = 12/41; P = 0.0268).

CONCLUSIONS

Based on both subjective and objective measures, pessaries are an effective conservative treatment option for SUI. This supports pessary use, though larger studies with longer-term follow-up are warranted.

Relevance of dog as an animal model for urologic diseases

We utilize animal models in urologic research to improve understanding of urinary physiology, determine the etiology of many urologic diseases, and discover and test novel therapeutic interventions. Dogs have a similar urinary tract anatomy and physiology to human and they develop many urologic diseases spontaneously. This chapter offers detailed comparisons of urinary tract anatomy, physiology, and the most common urologic diseases between humans and dogs. Dogs offer a unique opportunity for urologic research because they can be studied in research colonies and in client owned cohorts. Dogs also are among a limited number of non-human species that require continence and socially appropriate urinary behaviors (ex. going to the bathroom outside, training to not have submissive urination, etc.). These features make dogs unique in the animal kingdom and make them an ideal animal model for urologic research.

Electroacupuncture for stress-related urinary incontinence in elderly women: data analysis from two randomised controlled studies

OBJECTIVE

To compare the efficacy of electroacupuncture (EA) in elderly and non-elderly women with stress urinary incontinence (SUI) or stress-predominant mixed urinary incontinence (MUI).

METHODS

This study was a secondary analysis of two randomised controlled trials involving 252 women with SUI and 132 women with stress-predominant MUI who were treated with the same EA regimen. Elderly women were defined as those aged >60 years. The main outcome measure was the proportion of patients with ≥50% decrease in the mean 72-hour urinary incontinence episode frequency (IEF) from baseline to week 6. Overall, 1004 women were recruited in the SUI and MUI trials. In the EA group, those with urge-predominant or balanced MUI at baseline were excluded from the current study, resulting in a sample size of 384.

RESULTS

Out of 384 patients with SUI or stress-predominant MUI who were treated with EA, 371 completed the study. After 6-week treatment, the proportion of women who achieved ≥50% decrease in mean 72-hour IEF from baseline was 57.3% (51/89) in the elderly group and 60.70% (173/285) in the non-elderly group; the between-group difference was not significant (3.11%, 95% CI -9.83% to 16.05%; p=0.637). Similar outcomes were observed at weeks 4, 16 and 28. Both groups showed reduction in the 72 -hour IEF, amount of urine leakage (assessed by 1-hour pad test) and International Consultation on Incontinence Questionnaire-Short Form score from baseline with no significant between-group difference. No obvious EA-related adverse events were observed during the study.

CONCLUSION

EA may be an effective and safe alternative treatment for SUI or stress-predominant MUI in both elderly and non-elderly women. Age may not affect the treatment outcomes of acupuncture.

Home-based noninvasive pelvic floor muscle training device to assist women in performing Kegel exercise in the management of stress urinary incontinence

BACKGROUND

Stress urinary incontinence (SUI) is a major health problem affecting approximately 50% of the female population over 45 years of age. We evaluated the therapeutic effects of a home-based non-invasive wireless sensor pelvic floor muscle training (PFMT) device with assisted Kegel exercise for SUI.

METHODS

We included 60 women 40 to 60 years of age who were diagnosed with urodynamic SUI (mean pad test, 10.52 g). The PFMT device applicator was clamped on the upper inner thigh, and the patients could self-train at home. The signal was recorded and delivered to a 3G/4G smartphone via Bluetooth, which also allows guided feedback via the smartphone's voice. To evaluate the therapeutic effect, all patients completed the following questionnaires: a 3-day bladder diary, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the Urogenital Distress Inventory-Short Form, and the Incontinence Impact Questionnaire-7 (IIQ-7). One-hour pad test measurements were performed before the test (M0) and at 1 (M1), 2 months (M2), and 3 months (M3) after the PFMT device-assisted Kegel exercise.

RESULTS

The 1-hour pad test and the scores of the ICIQ-SF, UDI-6, and IIQ-7 questionnaires were improved at M1, M2, and M3, compared with the M0 values. The mean value of the post-voiding residual urine (PVR) significantly decreased at M2 and M3. The subjective and objective improvement rates at M3 were 80% and 72%, respectively.

CONCLUSION

The data demonstrated that 3 months of Kegel exercise assisted with a home-based PFMT device improved the number and severity of episodes, PVR, and quality of life in patients with SUI, suggesting that this device might serve as an alternative non-invasive therapy for mild and moderate SUI.

Molecular Processes in Stress Urinary Incontinence: A Systematic Review of Human and Animal Studies

Stress urinary incontinence (SUI) is a common and burdensome condition. Because of the large knowledge gap around the molecular processes involved in its pathophysiology, the aim of this review was to provide a systematic overview of genetic variants, gene and protein expression changes related to SUI in human and animal studies. On 5 January 2021, a systematic search was performed in Pubmed, Embase, Web of Science, and the Cochrane library. The screening process and quality assessment were performed in duplicate, using predefined inclusion criteria and different quality assessment tools for human and animal studies respectively. The extracted data were grouped in themes per outcome measure, according to their functions in cellular processes, and synthesized in a narrative review. Finally, 107 studies were included, of which 35 used animal models (rats and mice). Resulting from the most examined processes, the evidence suggests that SUI is associated with altered extracellular matrix metabolism, estrogen receptors, oxidative stress, apoptosis, inflammation, neurodegenerative processes, and muscle cell differentiation and contractility. Due to heterogeneity in the studies (e.g., in examined tissues), the precise contribution of the associated genes and proteins in relation to SUI pathophysiology remained unclear. Future research should focus on possible contributors to these alterations.

Comparison of Autologous Rectus Fascia and Synthetic Sling Methods of Transobturator Mid-Urethral Sling in Urinary Stress Incontinence

Objective: This study aims to compare the efficacy and complications between mesh obtained from the autologous rectus fascia and synthetic mesh used in transobturator tape procedure in the surgical treatment of urinary stress incontinence.

Methods: A total of 62 female patients who underwent operation due to urinary stress incontinence were included in the study. From these, 31 patients underwent autologous rectus fascia with mid-urethral sling (Group 1), and the remaining 31 patients underwent the same operation using synthetic multilaminar propylene sling (Group 2). The groups were compared preoperative and postoperative according to results of Urogenital Distress Inventory-Short Form (UDI-6) and Incontinence Impact Questionnaire-Short Form (IIQ-7). Demographic characteristics, surgical features, and complications were also compared between the groups. P < 0.05 values were considered statistically significant.

Results: The mean age was found as 54.74 ± 0.87 in Group 1 and 55.58 ± 0.76 in Group 2. There was no significant difference between the groups in terms of the preoperative and postoperative UDI-6 results ​​(p=0.258, p=0.349). Similarly, the preoperative and postoperative IIQ-7 results did not show a significant difference between the groups (p=0,483, p=0,367). There was also no significant difference in demographic characteristics and complications between the groups. Only the mean operational time was significantly longer in Group 1 (p=0.029).

Conclusion: Transobturator tape procedure with autologous rectus fascia is as effective and safe as synthetic mesh. This procedure provides an inexpensive and consumable option without posing a risk of mesh erosion and with low complication rates.

Exploratory safety study of an umbilical cord derived urethral sling in bilateral pudendal nerves injury-induced urinary incontinence in female rats

PURPOSE

Mid-urethral slings are the standard treatment for women with refractory stress urinary incontinence (SUI) but are at risk of infection or erosion due to host-prothesis interaction. In this proof-of-concept study, we aimed at evaluating umbilical vessel sling (UVS) in incontinent female rats.

MATERIAL AND METHODS

UVS was extracted from human umbilical cord lining and was placed on female rats who underwent bilateral pelvic nerve injury (PNI) to reproduce SUI (Group 3, N = 10). Two control groups were also studied: rats with no PNI (Group 1, N = 4) and rats with PNI but no UVS (Group 2, N = 10). Micturition calendar was frequently recorded using a metabolic cage, and leak point pressure (LPP) test was performed on Day 28. After the LPP test, rats were euthanized, and bladder/urethra were collected for histopathological analysis.

RESULTS

Overall, 24 rats were included, of whom 10 had both PNI and UVS placement. Compared with Group 2, Group 3 had increased maximal LPP but the difference did not reach significance (respectively 21.8 ± 2.1 mmHg vs. 28.4 ± 4.1 mmHg, p = 0.2). Micturition frequencies were similar between the groups. Total voided volume was higher in Group 3 at the end of the study compared with Group 2 (12.5 ± 1.1 ml vs. 9.4 ± 0.6 ml, respectively, p < 0.05). Histopathological findings evidenced a good local tolerance and a moderate to high tissue integration of the UVS.

CONCLUSIONS

Biological sling derived from human umbilical vessel could be safely placed with a slight improvement of LPP in a population of rats who had bilateral PNI without major modification of micturition calendar. UVS could be a promising biomaterial in the management of SUI in women. Clinical studies are needed.

A Review of Aging and the Lower Urinary Tract: The Future of Urology

Lower urinary tract symptoms (LUTS) are common among elderly people, with significant effects on individuals, caregivers, and the wider health care system. As the elderly population with multiple comorbidities is increasing, the burden of LUTS will increase. This review describes the demographic trends in the aging society, changes in lower urinary tract function with aging, and deterioration of physical and cognitive function in aging, as well as what has been done regarding geriatric urology and what urologists should do to meet the health care needs of the aging population. Frailty and dementia are unmissable factors in the evaluation of elderly patients. Numerous reports have described associations between LUTS and frailty and between LUTS and dementia. Urologists must be aware of the multiplex physical, cognitive, and social characteristics of elderly people. Maintaining a geriatric viewpoint in the diagnosis, treatment, and management of elderly individuals with LUTS will fulfill the unmet needs of elderly people. It is also essential to discuss the treatment and management goals of LUTS with patients and caregivers. Active case identification, appropriate evaluations of LUTS and comorbidities, and a multidisciplinary approach with other health-care professionals are recommended for better treatment and management.

[Urinary incontinence: a good diagnosis as a basis for treatment]

Urinary incontinence: a good diagnosis as a basis for treatment Abstract. Abtract: Everyone has experienced incontinence at an early age. However, it also affects approximately 200 million people worldwide at the adult age. This common condition is frequently underreported by patients but can dramatically limit their social life. Subject to appropriate differential diagnosis, urinary incontinence is a condition that can be treated with good results in the majority of patients. This article provides a review of the essential symptomatology and current treatments, so that clinicians confronted with the problem may adopt the appropriate management.

Perinatal mesenchymal stromal cells of the human decidua restore continence in rats with stress urinary incontinence induced by simulated birth trauma and regulate senescence of fibroblasts from women with stress urinary incontinence

Stress urinary incontinence (SUI) is a condition that causes the involuntary loss of urine when making small efforts, which seriously affects daily life of people who suffer from it. Women are more affected by this form of incontinence than men, since parity is the main risk factor. Weakening of the pelvic floor tissues is the cause of SUI, although a complete understanding of the cellular and molecular mechanisms of the pathology is still lacking. Reconstructive surgery to strengthen tissue in SUI patients is often associated with complications and/or is ineffective. Mesenchymal stromal cells from the maternal side of the placenta, i.e. the decidua, are proposed here as a therapeutic alternative based on the regenerative potential of mesenchymal cells. The animal model of SUI due to vaginal distention simulating labor has been used, and decidual mesenchymal stromal cell (DMSC) transplantation was effective in preventing a drop in pressure at the leak point in treated animals. Histological analysis of the urethras from DMSC-treated animals after VD showed recovery of the muscle fiber integrity, low or no extracellular matrix (ECM) infiltration and larger elastic fibers near the external urethral sphincter, compared to control animals. Cells isolated from the suburethral connective tissue of SUI patients were characterized as myofibroblasts, based on the expression of several specific genes and proteins, and were shown to achieve premature replicative senescence. Co-culture of SUI myofibroblasts with DMSC via transwell revealed a paracrine interaction between the cells through signals that mediated DMSC migration, SUI myofibroblast proliferation, and modulation of the proinflammatory and ECM-degrading milieu that is characteristic of senescence. In conclusion, DMSC could be an alternative therapeutic option for SUI by counteracting the effects of senescence in damaged pelvic tissue.

Efficacy evaluation of Lattice Carbon Dioxide Laser Therapy in the treatment of postmenopausal patients with mild to moderate stress urinary incontinence

Objectives

To investigate the efficacy and postoperative complications of lattice carbon dioxide laser in the treatment of postmenopausal patients with mild to moderate stress urinary incontinence.

Methods

A total of 30 postmenopausal female patients with mild to moderate stress urinary incontinence, recruited from the Affiliated Hospital of Hebei University from September to November 2019, were selected as the study subjects and treated with lattice carbon dioxide laser therapy. Treatment was given at intervals of one month. The degree of urinary incontinence, the urinary incontinence questionnaire (ICI-Q-SF) score, and the urinary incontinence quality of life scale (I-QOL)) Score, surgical satisfaction, one hour pad test and postoperative complications before treatment and after each treatment of all patients were respectively recorded and compared.

Results

Compared with those before treatment, the grade of urinary incontinence and ICI-Q-SF scores of these 30 patients after each treatment were lower, and their I-QOL scores were higher. The difference of one hour urine pad test was statistically significant (P<0.05), but the follow-up data of three months after the third treatment was close to that of one month after the first treatment. The satisfaction rate of these 30 patients was 76.67% (23/30). After treatment, only one patient presented vaginal itching discomfort on the first day after surgery and the symptoms disappeared three days later. No obvious complications occurred in the other 29 patients.

Conclusion

The treatment of mild and moderate postmenopausal patients with stress urinary incontinence with lattice carbon dioxide laser can effectively reduce the incidence of incontinence and improve the quality of life.

Stress Urinary Incontinence Among Young Nulliparous Female Athletes

Urinary incontinence (UI) is described as unintentional voiding of urine that is usually seen in post-partum and post-menopausal women due to the weakening of pelvic floor muscles (PFM). Recent studies have shown an increase in the prevalence of stress urinary incontinence (SUI) among young nulliparous female athletes. The association between UI and high-impact physical activity is due to increased intra-abdominal pressure during high-impact sports exceeding intra-urethral pressure. Usually, the levator ani muscle (LAM) helps in urethral closure. However, weakening or injury of LAM can reduce the pelvic support and cause UI in young female athletes. This study aims to assess the prevalence of SUI among young nulliparous athletes and also explore the association between SUI and athletic sports in young females. We searched PubMed and Google Scholar as databases to find specific articles about the topic. After the inclusion and exclusion criteria were applied, 52 articles were selected for this review. It is found that there is an increased UI prevalence, mainly SUI, among young nulliparous female athletes, especially in volleyball players and long-distance runners. Nulliparous athletes involved in high-impact exercises were found to have an increased cross-sectional area of LAM and puborectalis muscle width. SUI is usually under-reported and underdiagnosed due to lack of knowledge and unawareness, which can negatively affect the personal and social life of young females. PFM training is considered the first line of therapy among nulliparous athletes. However, it is unclear whether the high-impact effects of sports cause UI through PFM fatigue or PFM damage. More research is needed to better understand this effect.

Prevalence, social impact and help-seeking behaviour among women with urinary incontinence in the Gulf countries: A systematic review

BACKGROUND

Urinary incontinence (UI) in women is a common problem worldwide. It has a major impact on the physical and social activities and interpersonal relationships. The societies in the Gulf countries are conservative and favours large families, high parity and short inter-pregnancy intervals. Moreover, there is a high prevalence of gestational diabetes with many macrosomic babies. This study aimed to review the published literature on UI among women in this region.

METHODS

All published literature which investigated the prevalence, social impact and help-seeking behavior in women with UI in the Gulf countries was reviewed.

RESULTS

Nine studies met the criteria and were very heterogeneous. None of them was a true population-based study and all except one, investigated subjects from healthcare facilities. The prevalence of UI ranged from 20.3% to 54.5%. Stress UI was the main type reported. The main predisposing factors were chronic respiratory diseases and constipation. There was a large impact on the quality of life with major interference with prayers (34-90%) and sexual relationships (18-57%). The main reasons for not seeking medical advice were embarrassment to see doctors especially male doctors and the belief that UI is common, normal or incurable disease.

CONCLUSIONS

There is a need for true whole population-based studies of UI in this region with the use of validated international questionnaires. UI was shown to have a major impact on the act of prayers and sexual relationships. A large proportion of women are still embarrassed to discuss the issue with doctors especially male doctors.

Adjustable continence therapy (ACT®) balloons to treat neurogenic and non-neurogenic female urinary incontinence

AIMS

To compare efficacy and safety between neurogenic and non-neurogenic women after adjustable continence therapy (ACT®) balloons implantation to treat stress urinary incontinence (SUI) due to intrinsic sphincter deficiency.

METHODS

In the present retrospective multicentric study, all neurogenic and non-neurogenic women implanted with ACT® balloons between 2000 and 2018 were considered for inclusion. Efficacy was compared 1 year after implantation, and women were allocated in three different groups as follows. Success: maximum 1 pad per day and patient's impression of improvement assessed using a numeral rating scale (NRS) ≥8/10. Improvement: decrease of daily pad use and/or NRS ≥5/10. Failure: increase or stability of daily pad use or NRS <5/10. Overall surgical complications and explantations were compared 1 year after implantation.

RESULTS

Among the 277 included women, 51 presented with a neurologic underlying disease. Mean age at implantation was 68.5 years. There was no significant difference in efficacy between neurogenic and non-neurogenic women with a success rate of 39.2% and 36.3%, respectively (p = 0.69). Similarly, improvement rate was reported to be 31.4% and 33.6%, in neurogenic and non-neurogenic women, respectively (p = 0.92). The overall surgical complications rate (24% vs. 34.5%, p = 0.15) and the explantation rate (19.6% vs. 28.8%, p = 0.18) were not significantly different.

CONCLUSION

ACT balloons may be proposed to treat mixed or SUI in females with ISD. Efficacy and safety profiles appear to be similar in both neurogenic and non-neurogenic patients.

Stress urinary incontinence in females. Diagnosis and treatment modalities – past, present and the future

Introduction:

Stress urinary incontinence (SUI) can be defined as involuntary and unintentional loss of urine through the urethra when vesical pressure exceeds the urethral sphincter pressure during instances of coughing, sneezing or physical exercise. Stress urinary incontinence is the most common form of incontinence in females with an estimated prevalence of 4.5–53% in adult women with urinary incontinence. Yet despite its distressing nature and a negative impact on quality of life, very few women present with their symptoms to a urologist.

Materials and methods:

A literature search of the MEDLINE, Cochrane Library, Embase, NLH, ClinicalTrials.gov and Google Scholar databases was done up to November 2020, using terms related to SUI, medical therapy, surgical therapy and treatment options. The search terms included female stress urinary incontinence, mid-urethral sling, tension-free vaginal tape and trans obturator tape. The search included original articles, reviews and meta-analyses.

Conclusion:

Current guidelines for the management of stress urinary incontinence propose a step-ladder pattern, based on treatment invasiveness starting from conservative therapies, then drugs followed by minimally invasive procedures and culminating in invasive surgeries. The surgical approach is to be considered only after conservative therapies fail. The recent advances in the treatment of stress urinary incontinence have brought to light newer modalities and newer technologies that can be utilized which include laser therapy, stem cell therapy, intravesical balloon and others that show a lot of promise. This paper provides an in-depth analysis and reviews the literature on the current modalities and the future prospects of female stress urinary incontinence.

Long-term outcomes of Altis® single-incision sling procedure for stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

In women with predominant stress urinary incontinence (SUI), recent data are still controversial regarding the short-term outcomes of mini-slings and there is a lack of evidence about the outcomes in the long term. Our aim was to evaluate the long-term effectiveness and complication rates of Altis® (Coloplast).

METHODS

A total of 145 women with clinical SUI were implanted with an Altis® sling between April 2012 and December 2015. Women completed the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) before the intervention and in the following consultations. A telephone interview was performed in January 2021 and 131 women (90%) were available for re-evaluation. The main outcome was treatment success, defined as no self-reported SUI symptoms and no reintervention. Secondary outcomes included response to ICIQ-SF (cure defined as ICIQ-SF = 0) and Patient Global Impression of Improvement (PGI-I) questionnaires, de novo overactive bladder (OAB) symptoms and adverse events.

RESULTS

The overall treatment success was 73.3% at a median follow-up of 8 years. The ICIQ-SF cure rate was 66.1%. In the PGI-I, 70.4% answered that they were much better or very much better. Later postoperative complications included 2 cases (1.5%) of vaginal extrusion (requiring surgical removal of the eroded mesh segment), 3 (2.3%) cases of infravesical obstruction (which led to sling section), de novo urgency in 20 patients (15.3%), and mild dyspareunia in 2 (1.5%) patients.

CONCLUSIONS

The Altis® sling was safe and effective in a long-term follow-up, improving the quality of life in patients with SUI.

A systematic review of utility-based and disease-specific quality of life measurement instruments for women with urinary incontinence

AIM

This systematic review aims to identify disease-specific and generic quality of life (QoL) outcome measurement instruments used in populations of women with urinary incontinence (UI) and to determine the most psychometrically robust and appropriate disease-specific and generic tools for measuring the quality of life in this population.

METHODS

A systematic search was conducted of PubMed, Embase, SCIELO, and CINAHL databases for studies evaluating measurement properties of QoL instruments in women with UI. The methodological quality of studies and the quality of measurement properties were evaluated using the COnsensus-based Standards for the selection of health status Measurement INtruments (COSMIN) checklist and quality criteria. Overall, evidence for measurement properties was graded using the modified grading of recommendations, assessment, development & evaluation approach.

RESULTS

A total of 73 studies were included, and 27 specific and 6 generic instruments were identified. The Incontinence QoL questionnaire (IQoL) had the highest overall psychometric quality for English-speaking populations and was the most widely translated tool. Evidence for generic QoL tools in this population is limited. Few studies evaluated measurement error or cross-cultural validity.

CONCLUSION

The IQoL is the most psychometrically robust disease-specific tool for use in this population. More research is needed to determine the most psychometrically robust generic tool. Future studies should also evaluate measurement error and cross-cultural validity as evidence for these properties is particularly lacking.
