Introduction and hypothesis
The objective of this narrative review is to describe changes in urethral function that occur during a woman’s lifetime. Evaluation of urethral function includes ...measurements of urethral closure pressure, at rest and during stress, leak point pressure, and the detailed study of anatomical and histological changes of the urethral sphincteric mechanism.
Methods
A literature search in MEDLINE, PubMed, and relevant journals from 1960 until 2020 was performed for articles dealing with urethral function and the impact of aging, pregnancy, and childbirth, female hormones, and menopausal transition on the urethral sphincteric mechanism. Longitudinal and cross-sectional epidemiological surveys, studies on histological changes in urethral anatomy during aging, and urodynamic data obtained at different points in a woman’s lifetime, during pregnancy, after childbirth, as well as the effects of female hormones on urethral sphincter function are reviewed. Relevant studies presenting objective data are analyzed and briefly summarized.
Results and conclusions
The findings lead one to conclude that a constitutional or genetic predisposition, aging, and senescence are the most prominent etiological factors in the development of urinary incontinence and other pelvic floor disorders. Vaginal childbirth dilates and may damage the compressed pelvic supportive tissues and is invariably associated with a decline in urethral sphincter function. Pregnancy, hormonal alterations, menopausal transition, weight gain, and obesity are at best of secondary influence on the pathology of lower urinary tract dysfunction. The decline of circulating estrogens during menopausal transition may play a role in the transition of fibroblasts to cellular senescence.
Nocturia is a bothersome, multifactorial condition with many underlying causes and contributing factors. Nocturnal polyuria (NP; overproduction of urine at night) is a frequent component. The ...prevalence of nocturia increases with age; specific estimates of prevalence are influenced by frequency thresholds used to define it. There is a tendency toward higher prevalence in young women than young men, which is reversed in later life.
The association between frequency of nocturnal voiding and sleep disruption is well-documented. Nocturia correlates strongly with shorter sleep during the first part (2-4 hours) of the night, during which the first nocturnal void often occurs. A short time to first void after sleep onset (often referred to as “first uninterrupted sleep period”) is associated with increased daytime dysfunction and decreased sleep quality and/or sleep efficiency.
Adverse health consequences related to nocturia include poor sleep, depression, reduced quality of life, and increased risk of morbidity, mortality, falls, and fractures; studies have been able to establish a causal role for nocturia in only some of these.
The potential impact of nocturia on health increases with age. By age 80, 80% of people will rise at least once per night to void. Despite its associated bother, nocturia is often accepted as a natural consequence of aging and many people do not seek help. Women, in particular, may be reluctant to report nocturia.
This article reviews the prevalence of nocturia, possible impact on sleep, mortality and morbidity, and falls, and its importance in the elderly/frail population and women.
Introduction and hypothesis
Next to existing terminology of the lower urinary tract, due to its increasing complexity, the terminology for pelvic floor dysfunction in women may be better updated by a ...female-specific approach and clinically based consensus report.
Methods
This report combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS), assisted at intervals by many external referees. Appropriate core clinical categories and a subclassification were developed to give an alphanumeric coding to each definition. An extensive process of 15 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus).
Results
A terminology report for female pelvic floor dysfunction, encompassing over 250 separate definitions, has been developed. It is clinically based with the six most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Female-specific imaging (ultrasound, radiology, and MRI) has been a major addition while appropriate figures have been included to supplement and help clarify the text. Ongoing review is not only anticipated but will be required to keep the document updated and as widely acceptable as possible.
Conclusions
A consensus-based terminology report for female pelvic floor dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research.
To evaluate the safety and efficacy of the eCoin - a nickel-sized, primary battery-powered, neuromodulation device for the treatment of urgency urinary incontinence which is implanted in the lower ...leg in a 20-minute procedure under local anesthesia. A feasibility clinical trial was conducted and the results after 1 year of treatment with the eCoin are presented.
A total of 46 participants with refractory urgency urinary incontinence were included in this prospective, single-arm, open-label study. This study was conducted at 7 sites in the United States and New Zealand. Participants in this study were implanted with the eCoin in the lower leg over the tibial nerve and activated after 4 weeks. Bladder diary data and validated quality-of-life instruments, collected at 3, 6, and 12 months’ post-activation, were compared to baseline values.
Responders were defined as those who had a ≥50% reduction in reported episodes of urgency urinary incontinence. At 12 months’, 65% of participants were considered responders with 26% of participants achieving complete continence. The median number of urgency urinary incontinence episodes per day decreased from 4.2 at baseline to 1.7 at 12 months’. Seventy percent of participants reported feeling “better”, “much better”, or “very much better” on the Likert 7-point maximum scale. One participant experienced a related serious adverse event.
The eCoin is a safe and effective treatment for urgency urinary incontinence associated with overactive bladder syndrome, with significant reduction or complete resolution of symptoms and no significant safety concerns.
Purpose We evaluated the efficacy, tolerability and safety of the new antimuscarinic agent fesoterodine relative to placebo for overactive bladder syndrome. Materials and Methods This was a ...randomized, double-blind, placebo controlled, multicenter trial performed in the United States. Overall 836 subjects with urinary frequency, urinary urgency or urgency urinary incontinence were randomized to placebo (274), 4 mg fesoterodine (283) or 8 mg fesoterodine (279) once daily for 12 weeks. The primary efficacy end point was the change in the number of micturitions per 24 hours. Co-primary end points were the change in the number of urgency urinary incontinence episodes per 24 hours and the treatment response. Secondary efficacy end points were other bladder diary variables, such as the change in mean voided volume per micturition, number of continent days and number of urgency episodes per 24 hours. Tolerability and safety were assessed by evaluating adverse events, electrocardiograms, post-void residual urine volume, laboratory parameters and treatment withdrawals. Results Treatment with 4 or 8 mg fesoterodine resulted in statistically significant and clinically relevant improvements from baseline to end of treatment for the primary and co-primary end points compared with placebo (p <0.05). Results for most secondary end points, including mean voided volume per micturition, number of continent days and number of urgency episodes per 24 hours, were also significantly improved vs placebo. The adverse events reported more frequently with fesoterodine than with placebo were dry mouth, constipation and urinary tract infection. Conclusions The 2 doses of fesoterodine were well tolerated and they statistically significantly improved overactive bladder symptoms.
Purpose Previous studies suggest a lower dose of desmopressin orally disintegrating tablet may be effective in females compared to males with nocturia. We confirm the efficacy and safety of 25 μg ...desmopressin orally disintegrating tablet compared to placebo in female patients. Materials and Methods In this 3-month, randomized, double-blind, parallel group study 25 μg desmopressin once daily was compared to placebo in women with nocturia (2 or more nocturnal voids). The co-primary efficacy end points were change from baseline in mean number of nocturnal voids and proportion of patients achieving at least a 33% reduction from baseline in the mean number of nocturnal voids (33% responders). Results The full analysis set comprised 261 patients (age range 19 to 87 years). Desmopressin significantly reduced the mean number of nocturnal voids and increased the odds of a 33% or greater response compared to placebo during 3 months, assessed by longitudinal analysis (−0.22, p = 0.028 and OR 1.85, p = 0.006, respectively). Desmopressin increased the mean time to first nocturnal void by 49 minutes compared to placebo at 3 months (p = 0.003). The response to desmopressin was seen by week 1 of treatment and was sustained throughout the trial. Significant increases in health related quality of life and sleep quality were observed compared to placebo. Desmopressin was well tolerated. Serum sodium levels remained greater than 125 mmol/L throughout the trial and 3 transient decreases to less than 130 mmol/L were recorded. Conclusions At a dose of 25 μg, desmopressin orally disintegrating tablet is an effective and well tolerated treatment for women with nocturia. Treatment provides rapid and sustained improvement in nocturia and quality of life.

The Sino-Nasal Outcome Test 22 (SNOT-22) is a validated patient-reported outcome instrument to evaluate the health-related quality of life (HRQoL) in patients with chronic rhinosinusitis (CRS). There ...are no published normative SNOT-22 scores, limiting its interpretation.
Symptom scores from 1,000 SNOT-22 questionnaires were analysed by principal component analysis (PCA) and exploratory factor analyses. Data were derived from a survey with 1,000 healthy Europeans (reference cohort) who were recruited using the Respondi panel for market and social science research. This subsample was quoted to the population distribution of the German Microcensus and selected from a non-probability panel.
The overall normative SNOT-22 score can be detected to be 20.2 ± 19.44. Male (18.49 ± 19.15) and older (> 50 years old; 18.3 ± 17.49) participants had overall lower SNOT-22 mean results than females (21.8 ± 19.6) and younger (21.4 ± 20.55) participants, indicating higher levels of satisfaction. PCA proposed two SNOT-22 domains ("physiological well-being" and "psychological well-being"), which explained 65% of the variance.
These are the first published (German) normative scores for the SNOT-22 and provide a clinical reference point for the interpretation of data.
