Primary enuresis in adults: pathogenesis, clinical course and modern approaches to treatment: A review

The review article presents current data on the epidemiology, classification, pathogenesis, risk factors, diagnosis, and features of the clinical course of primary enuresis in adults. The main methods of treatment of patients with primary enuresis are described in detail. It has been shown that in the treatment of this category of patients, the leading role is given to the use of a synthetic analogue of the antidiuretic hormone desmopressin. A detailed analysis of the pharmacological properties and clinical use of desmopressin in patients with primary enuresis is presented. The advantages of prescribing a sublingual form of desmopressin, which ensures its high efficiency and good tolerability of therapy.

The relative importance of different consequences of nocturnal enuresis among older women: A conjoint analysis experiment

INTRODUCTION

Adult nocturnal enuresis (NE) is an understudied and bothersome condition. Our objective was to conduct a conjoint analysis experiment to better understand the relative importance of NE consequences in older women.

METHODS

We developed a conjoint analysis survey that included four attributes related to NE (awakening at night, feeling rested in the morning, restricting fluid before bed, and wet perineal skin). We performed a prospective cross-sectional online study of women >62 years of age with NE using Sawtooth Software. Patients completed baseline questions, the International Consultation on Incontinence Questionnaire-nocturia Quality of Life (ICIQ-NqoL), and the conjoint analysis experiment. Hierarchical Bayes random effects regression analysis was used to determine the relative importance of the four attributes.

RESULTS

A total of 200 women with a mean age of 71 years completed the study. The most common management of NE was diapers/pads (132/200). Approximately half of the participants experienced NE several times a week or nightly (101/200). The most important attribute was the frequency of being awakened at night (34, standard deviation [SD]: 16) and the frequency of feeling rested in the morning (32, SD: 15). Limiting drinking before bed (18, SD: 12) and wet groin skin (16, SD: 10) had significantly lower importance scores (p < 0.05). Age, sleeping with a partner in bed, body mass index, NE severity score, and the ICIQ-NqOL score were not significantly associated with any of the importance scores.

CONCLUSIONS

Older women with NE place significantly more importance on the frequency of awakening at night, and feeling rested in the morning and lesser importance on associated lifestyle or physical manifestations of NE.

The Clinical Features and Predictive Factors of Nocturnal Enuresis in Adult Women

Objective

Our current knowledge on nocturnal enuresis (NE) in adults is scarce due to its uncommon nature. The present study was designed to investigate symptom characteristics and risk factors of NE in adult women to improve the current clinical understanding and management of this rare disease.

Methods

Over a 3-year period, we enrolled 70 adult women who complained of bedwetting, with a frequency of at least once per week and a symptom duration of 3 months or longer. Patients were excluded if they had known pregnancy, current urinary tract infection, untreated malignancies, anatomical abnormalities, and irregular sleep cycle. The International Consultation on Incontinence Modular Questionnaire—female lower urinary tract symptoms and bladder diary were employed to appraise lower urinary tract symptoms and voiding behavior. Urodynamics was performed to assess the bladder function. A linear regression analysis was applied to determine potential risk factors for NE frequency.

Results

Among the recruited subjects, comorbidities and lower urinary tract symptoms were frequently reported. On bladder diary, patients commonly presented with nocturnal polyuria (NP), reduced nocturnal voided volumes (RNVVs), or both. Urodynamics revealed multiple dysfunctions, namely, detrusor overactivity (DO), urodynamic stress incontinence (USI), reduced compliance, bladder outlet obstruction, detrusor underactivity (DU), and simultaneous DO and DU. Patients with more frequent NE (≥4/week) demonstrated markedly increased body mass index, more comorbid conditions, worse incontinence symptoms, NP or NP plus RNVVs, reduced compliance, and poorer voiding possibly owing to DU. Whereas, RNVVs alone and worse overactive bladder-related parameters were associated with milder NE. Multivariate analysis indicated that frequency/urgency quality of life, incontinence symptom, NP + RNVVs, poor flow, increased bladder sensation, USI, and simultaneous detrusor overactivity plus DU were independent risk factors for NE severity.

Conclusion

NE in adult women may have both urological and non-urological pathophysiology. Imbalanced circadian urine production, jeopardized continence mechanisms, overactive bladder, and DU-induced poor voiding are major factors that contribute to the pathogenesis of NE in adult women. Focused treatments on restoring these functions should be individually considered.

Assessment and Treatment of Nocturia in Neurological Disease in a Primary Care Setting: Systematic Review and Nominal Group Technique Consensus

CONTEXT

Neurological disease can affect the rate of urine production and bladder storage function, increasing nocturia severity, with additional risks if mobility or cognition is impaired.

OBJECTIVE

To conduct a systematic review (SR) of nocturia in neurological diseases and achieve expert consensus for management in clinics without neurologist input.

EVIDENCE ACQUISITION

Four databases were searched from January 2000 to April 2020. A total of 6262 titles and abstracts were screened and 43 studies were included for full-text screening. Eleven of these met the inclusion criteria and two studies were identified through other sources. The nominal group technique (NGT) was used to develop consensus in panel comprising experts and public representation.

EVIDENCE SYNTHESIS

Thirteen studies (seven in Parkinson's disease, five in multiple sclerosis) were included, all undertaken in secondary care. Neurological disease severity was incompletely described, and nocturia severity was generally measured subjectively. NGT consensus supported basic neurological assessment, and the use of bladder diaries where neurological impairment permits. Treatments include pelvic-floor muscle training, review of medications, risk mitigation, improving bowel function, therapy for overactive bladder syndrome (if urgency is reported in association with nocturia episodes), treatment of postvoid residual and desmopressin according to licence. Measures to improve mobility and mitigate risk when using the toilet overnight should be considered. Multifactorial issues such as obstructive sleep apnoea and hypoventilation must be considered.

CONCLUSIONS

Nocturia in neurological disease is complex and lacks a robust evidence base, with very little research done in the primary care context. Guidance should be pragmatic, with reduction of risk a key requirement, until a multidisciplinary evidence base can be developed.

PATIENT SUMMARY

People with a neurological disease can suffer severe sleep disturbance because of the need to pass urine several times overnight (called nocturia). We looked at published research and found very little information to help general practitioners in managing this condition. We assembled a group of experts to develop practical approaches for assessing and treating nocturia in neurological disease.

Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition)

The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

The clinical features and predictive factors of nocturnal enuresis in adult men

OBJECTIVES

To characterise the clinical features and to discover predictive factors of adult males with nocturnal enuresis (NE).

PATIENTS AND METHODS

A total of 43 eligible adult male patients (mean age was 57.8 years) were recruited prospectively over a 2-year period. After documentation of medical history, lower urinary tract symptoms (LUTS) were assessed using the International Consultation on Incontinence Modular Questionnaire-male LUTS (ICIQ-MLUTS), and a 3-day ICIQ-bladder diary (ICIQ-BD). Video-urodynamic studies (VUDS) were conducted conforming to the International Continence Society standards. Univariate and multivariate linear regressions were performed to determine potential predictive factors.

RESULTS

Patients with NE had a variety of LUTS and had a high incidence of obesity and comorbidities. On the ICIQ-BD, NE was associated with nocturnal polyuria (NP), reduced nocturnal bladder capacity (NBC), or a combination of both. Subgroup analysis indicated that patients with more frequent NE had: higher body mass index (BMI); more comorbidities; reduced daytime urinary frequency and urgency quality of life (QoL) sub-scores; and increased stress urinary incontinence (SUI) and nocturnal bedwetting sub-scores. Patients with reduced NBC only, had fewer NE episodes, while patients with NP, or with both NP and reduced NBC were more likely have frequent NE. Multivariate analysis confirmed that: BMI; neurogenic causes; sub-scores of SUI QoL and bedwetting domain; the presence of reduced NBC, and both NP and reduced NBC; and bladder outlet obstruction, were all independent predictive factors for the severity of NE.

CONCLUSIONS

NE n the adult male should be systemically assessed and treated, as obesity, neurogenic disorders, excessive urine production, bladder storage and emptying dysfunctions are risk factors. Bladder diaries and VUDS provide valuable information on potential pathophysiological causes, which could assist clinical evaluation and selection of focussed treatment.

Does smoking exposure affect response to treatment in children with primary monosymptomatic nocturnal enuresis?

BACKGROUND

There are many variables affecting the success of treatment in children with primary monosymptomatic nocturnal enuresis (PMNE). This study investigates the possible effect of cigarette smoke exposure on desmopressin treatment response in children with PMNE.

METHOD

The medical records of pediatric patients with PMNE between February 2018 and December 2018 were retrospectively reviewed. Those who had moderate (3-5 wet nights/week) and severe (>5 wet nights/week) PMNE were included in the study. All patients received 120 mcg of sublingual desmopressin. After 3 months of therapy, treatment response was classified as complete response (100% dry night), partial response (between 50% and 99%) and non-responsiveness (<49% improvement). Partial response or non-responsiveness is considered as treatment failure. The relationship between treatment response to desmopressin and exposure to cigarette smoke was evaluated. Moreover, the other risk factors for treatment failure were investigated.

RESULTS

A total of 81 children with the diagnosis of PMNE, with a mean age of 9.98 ± 2.62 years, were included in the study. The frequency of passive smoke exposure at home was 53.1%. Sixty-two patients (76.5%) had severe PMNE, and the response to desmopressin decreased with severity of symptoms. Non-responsiveness to treatment, partial response, and complete response were observed in 11 (13.6%), 23 (28.4%), and 47 (58.0%) of patients, respectively. Treatment failure (n = 34, 42%) was 55.8% in children exposed to smoke and 26.4% in those who were not (p = 0.001). Although univariate analysis revealed that the severity of symptoms and smoke exposure were associated with treatment failure, in multivariate analysis, the presence of smoke exposure was the only independent risk factor (OR = 3.214, 95% CI: 0.125-0.888; p = 0.024) (Summary Table 1).

CONCLUSION

Exposure to cigarette smoke is a changeable and important risk factor that reduces the success of desmopressin treatment in children with PMNE.

One and the Same? Nocturnal Enuresis and Overactive Bladder in the Female Veteran Population: Evaluation of a Large National Database

OBJECTIVES

The aims of this study were to describe relationships between women given a diagnosis of nocturnal enuresis (NE) and controls without any urinary complaints and to compare women with NE with those with overactive bladder (OAB). We hypothesized that NE has unique associations with demographics and medical and psychosocial diagnoses.

METHODS

This is a secondary analysis of a database that included all female veterans who established care with a primary care provider from 1997 to 2015. International Classification of Diseases, Ninth Revision, codes identified women with a diagnosis of NE or OAB. Patient characteristics, medical diagnoses, and psychosocial factors previously described as relating to NE and/or OAB were compared between the 2 distinct comparative groups, with significance set at P < 0.05. Stepwise logistic regression was used to assess all significant findings.

RESULTS

A total of 596,815 women were identified; controls totaled 570,049, the group with OAB totaled 26,446 (4.4%), and the group with NE totaled 301 (0.05%).Multivariable analysis compared the group with NE with controls; all measured psychosocial characteristics remained significantly associated with an NE diagnosis (all Ps < 0.05), as well as obstructive sleep apnea history, stroke, self-identification as "minority," smoking, hypertension, and a body mass index higher than those of the general control population (all Ps < 0.05).When the populations with NE and OAB were compared, a diagnosis of posttraumatic stress disorder, an overdose history, depression, military sexual trauma, increasing body mass index, and younger age remained significantly associated with NE (all Ps < 0.05).

CONCLUSIONS

The association of NE with psychosocial characteristics and psychiatric illnesses persisted irrespective of the comparison population. Practitioners should investigate the diagnosis of NE in those female veterans with psychosocial issues.

A comprehensive review of adult enuresis

Nocturnal enuresis (NE) is a combined symptom of nocturia and urinary incontinence. In this review, we aim to summarize the current literature on NE in terms of its definition, diagnosis, and management. Recommended diagnostic evaluation of NE includes a focused history and physical examination, urinalysis, and when indicated, ultrasound examination, flow rate, urine volume chart, urodynamics, and cystoscopy. Therapeutic options include lifestyle modification and medications (i.e., desmopressin and anticholinergics).

Urological disease and tobacco. A review for raising the awareness of urologists

CONTEXT

Smoking is the leading cause of preventable death in our community. Its relationship with urological disease is well documented.

OBJECTIVE

To present an updated review on the relationship between urological disease and tobacco consumption and the importance of involving urologists in smoking prevention.

ACQUISITION AND SYNTHESIS OF EVIDENCE

We conducted a review of current literature, primarily by searching PubMed and using as the main base the report on the consequences of smoking on health performed by the Surgeon General.

CONCLUSION

Urologists play an essential role in informing patients of the relationship between smoking and urological disease. It is the duty of every urologist to play a more active role in educating patients and promoting smoking cessation.

Nocturnal enuresis: prevalence and associated LUTS in adult women attending a urogynaecology clinic

INTRODUCTION

Nocturnal enuresis (NE) is an underreported symptom with a profound impact on quality of life. The primary objective of this study was to investigate the prevalence of NE and its association with other lower urinary tract symptoms (LUTS).

METHODS

A validated pelvic floor questionnaire [electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF)] was completed by 2302 women attending a urogynaecology clinic over a 3-year period. Association between NE and overactive bladder (OAB), stress incontinence (SUI) and nocturia was assessed using logistic regression. Subgroup analysis was performed on women with NE undergoing transvaginal tape (TVT). Ethical approval was acquired from the University of Sheffield and statistical analysis performed using SPSS version 22.

RESULTS

The overall prevalence of NE reported in the cohort was 23 % (536 women). The reporting of NE was significantly associated with OAB (p < 0.005), SUI (p < 0.005) and nocturia (p < 0.005). Of 84 women undergoing TVT, 49 % reported NE preoperatively. These women reported significantly more severe symptoms of SUI and OAB (p < 0.05). Sixty percent reported improvement or cure of NE postoperatively, and this was dependent on improvement or cure of SUI (p < 0.005). The presence of NE was a negative predictor for improvement in symptoms of SUI following TVT (p = 0.037).

CONCLUSION

This study provides insight into NE, a commonly reported symptom in women attending urogynaecology clinics. To our knowledge, this is the first study to implicate stress incontinence as an important aetiological factor in women with NE. Further studies are required to better understand the aetiology of NE in adult women and relate this to management and outcome.
