Lower urinary tract symptoms represent a significant public health problem worldwide, impairing patients' quality of life, especially in elderly people. Among LUTS, nocturia is assessed as the most experienced entity related to several disorders such as sleep disorders and/or obstructive sleep apnea syndrome (OSAS). Among OSAS patients, nocturia stands as a bothersome symptom that increases alongside with the OSAS severity. However, despite the nocturia and OSAS shared a long-acknowledged link, the causes, and the pathophysiology for development of nocturia in OSAS have remained largely unexamined. Generally, the patients with OSAS experienced nocturia due to easy waking or increased bladder filling. However, nor the effect of treatment on management of nocturia in OSAS patients are well-established.

Nocturnal polyuria (NP), characterized by overproduction of urine at night (greater than 20%-33% of total 24-hour urine volume depending on age), is a major contributing factor in most nocturia cases. Nocturia can be caused by intake, urological, nephrological, hormonal, sleep, and cardiovascular factors. It is therefore important to accurately diagnose both the type of nocturia and the potentially associated medical conditions to determine appropriate treatment. Diagnostic tools, in addition to a thorough history and physical examination, include voiding/bladder diary analyses and questionnaires to diagnose nocturia type (NP, diminished nocturnal/global bladder capacity, global polyuria) and causative factors. Lifestyle modifications are the first intervention implemented for the management of nocturia and NP but, as symptoms progress, such measures may be insufficient, and pharmacotherapy may be initiated. While drugs for benign prostatic hyperplasia and overactive bladder have demonstrated statistically significant reductions in nocturnal voids, patients often fail to achieve a clinically meaningful response. Antidiuretic treatment is warranted for patients with nocturia due to NP because, in many patients, it treats the underlying cause (ie, insufficient secretion of antidiuretic hormone arginine vasopressin) that leads to overproduction of urine at night and has been shown to provide statistically significant reductions in nocturnal voids. Desmopressin, a synthetic analog of arginine vasopressin, is the only antidiuretic treatment indicated specifically for nocturia due to NP. Overall, the pathophysiology of NP is complex and differs from that of other types of nocturia. A multidisciplinary approach is necessary to effectively diagnose and manage this bothersome condition.

BACKGROUND

Overactive bladder (OAB) symptoms of frequency, urgency and urge incontinence are frequently associated with known neurological diseases like multiple sclerosis (MS), spinal cord injury (SCI), Parkinson's disease (PD), stroke.

OBJECTIVE

The aim of our study was to review the efficacy of pharmacological and non-pharmacological treatments for neurogenic overactive bladder.

MATERIALS AND METHODS

We searched two electronic databases (PubMed and EMBASE) for randomized controlled trials focusing on pharmacological and non-pharmacological medical treatments for overactive bladder symptoms associated with neurological diseases published up to 30 April 2022.

RESULTS

A total of 157 articles were retrieved; 94 were selected by title and abstract screening; after removal of 17 duplicates, 77 records were evaluated by full-text examination. Sixty-two studies were finally selected. The articles selected for review focused on the following interventions: anticholinergics (n = 9), mirabegron (n = 5), comparison of different drugs (n = 3), cannabinoids (n = 2), intravesical instillations (n = 3), botulinum toxin (n = 16), transcutaneous tibial nerve stimulation (TTNS) (n = 6), acupuncture (n = 2), transcutaneous electrical nerve stimulation TENS (n = 4), pelvic floor muscle training (PFMT) (n = 10), others (n = 2). Anticholinergics were more effective than placebo in decreasing the number of daily voids in patients with PD (mean difference [MD]- 1.16, 95 % CI - 1.80 to - 0.52, 2 trials, 86 patients, p < 0.004), but no significant difference from baseline was found for incontinence episodes and nocturia. Mirabegron was more effective than placebo in increasing the cystometric capacity in patients with MS (mean difference [MD] 89.89 mL, 95 % CI 29.76 to 150.01, 2 trials, 98 patients, p < 0.003) but no significant difference was observed for symptom scores and bladder diary parameters. TTNS was more effective than its sham-control in decreasing the number of nocturia episodes (MD -1.40, 95 % CI -2.39 to -0.42, 2 trials, 53 patients, p < 0.005) but no significant changes of OAB symptom scores were reported. PFMT was more effective than conservative advice in decreasing the ICIQ symptom score (MD, -1.12, 95 % CI -2.13 to -0.11, 2 trials, 91 patients, p = 0.03), although the number of incontinence episodes was not significantly different between groups.

CONCLUSIONS

The results of the meta-analysis demonstrate a moderate efficacy of all considered treatments without proving the superiority of one therapy over the others. Combination treatment using different pharmacological and non-pharmacological therapies could achieve the best clinical efficacy due to the favorable combination of the different mechanisms of action. This could be associated with fewer side effects due to drug dosage reduction. These data are only provisional and should be considered with caution, due to the few studies included in metaanalysis and to the small number of patients.

Review

Overactive bladder syndrome is highly prevalent, and increasingly so with aging. It is characterized by the presence of urinary urgency, and can be associated with incontinence, increased voiding frequency, and nocturia. Assessment needs to exclude serious medical disorders that might present with similar symptoms, and a bladder diary is an invaluable part of understanding the presentation. Initial management is conservative, comprising education, bladder training, and advice on fluid intake. Drug therapy options include antimuscarinic medications and beta-3 adrenergic receptor agonists. Persistent overactive bladder syndrome, despite initial therapy, requires a review of the patient's understanding of conservative management and compliance, and adjustment of medications. For refractory cases, specialist review and urodynamic testing should be considered; this may identify detrusor overactivity or increased filling sensation, and needs to exclude additional factors, such as stress incontinence and voiding dysfunction. Botulinum neurotoxin-A bladder injections can be used in severe overactivity, provided the patient is able and willing to do intermittent self-catheterisation, which is necessary in about 5% of treated patients. Sacral nerve stimulation and tibial nerve stimulation are other approaches. Major reconstructive surgery, such as augmentation cystoplasty, is rarely undertaken in modern practice but remains a possibility in extreme cases.

BACKGROUND

Many studies have explored the association between diabetes and nocturia, but it remains unclear. This article systematically analyses existing evidence of the relationship between diabetes and nocturia, including subgroup analysis based on the number of voids, gender, and continent, in the hope of reaching more reliable clinical conclusions relating to diabetes and nocturia.

METHODS

PubMed, Web of Science, and Cochrane Library were searched for identifying studies relating to diabetes and nocturia prior to July 2021. Literature quality evaluation was performed using the Newcastle Ottawa Scale. A random effect meta-analysis was used for pooled odds ratios (ORs) and confidence intervals (CIs) as a means of evaluating the relationship between diabetes and nocturia.

RESULTS

In total, 29 of 781 potentially relevant studies were proven to be eligible. The overall pooled OR demonstrated that diabetes increases the risk of nocturia (OR: 1.49; 95% CI: 1.38, 1.61; < 0.00001). The association was found to be more robust among subjects ≥ 1 void than ≥ 2 void (OR: 1.74; 95% CI: 1.41, 2.14; < 0.00001 vs. OR: 1.45; 95% CI: 1.33, 1.59; < 0.00001), in males than females (OR: 1.59; 95% CI: 1.41, 1.79; < 0.00001 vs. OR: 1.41; 95% CI: 1.20, 1.66; < 0.0001) and in Asia than Europe or North America (OR: 1.54; 95% CI: 1.36, 1.75; < 0.00001 vs. OR: 1.43; 95% CI: 1.19, 1.72; = 0.0001 vs. OR: 1.45; 95% CI: 1.22, 1.73; < 0.0001).

CONCLUSIONS

Diabetes has an association with a 1.49-fold higher risk of nocturia. This association is more robust for Asian and male subjects or those at a lower nocturia cut-off.

PURPOSE OF REVIEW

To assess current pharmacological principles used for treatment of nocturia/nocturnal polyuria.

RECENT FINDINGS

The pathophysiology of nocturia is often multifactorial, but two main mechanisms have been identified, occurring alone or in combination: low functional bladder capacity and nocturnal polyuria. The multifactorial pathophysiology not only implies several possible targets for therapeutic intervention but also means that it is unlikely that one treatment modality including drugs will be successful in all patients. Drugs approved for the treatment of male LUTS and male and female OAB are known to be far more effective for treatment of the daytime symptoms than for nocturia. Several pharmacological principles have been tested with varying success. The treatment of choice should depend upon the main underlying cause, thus aiming primarily to increase bladder capacity by counteracting detrusor overactivity and/or reducing nocturnal polyuria. Using current available agents, effective, personalized treatment should be designed taking into account gender, co-morbidities, and identified etiological factors. However, there is a medical need for new, approved drugs for treatments for patients with nocturia.

Nocturia causes lack of sleep and excessive daytime somnolence, reducing overall well-being, vitality, productivity, and mental health. Nocturia is significantly associated with testosterone deficiency, lower urinary tract symptoms (LUTS), and sleep disorders. The development of LUTS is commonly associated with testosterone deficiency in elderly men, and recent studies have suggested that testosterone has an ameliorative effect on nocturia. In hypogonadal men with nocturia, a negative feedback cycle can arise, in which testosterone deficiency leads to the development of nocturia, and nocturia contributes to the decline in testosterone levels. Therefore, patients with nocturia should receive appropriate treatment in order to improve their quality of life. Nocturia is generally treated by restricting nighttime water intake, as well as by the administration of medications, such as alpha-1 blockers, anticholinergic drugs, and desmopressin. Testosterone replacement therapy (TRT) is used worldwide as a treatment for many hypogonadal conditions. TRT represents an alternative treatment option for nocturia in hypogonadal men. However, limited information is currently available regarding the effects of TRT on nocturia in hypogonadal men, and further studies are required to reach more definitive conclusions.

BACKGROUND

Nocturia is one of the commonest nonmotor symptoms in Parkinson's disease (PD) and has a significant impact on quality of life both for patients and their carers. There exists a relation between nocturia and poor sleep quality, falls, and institutionalization. Nocturia may manifest as a result of reduced functional bladder capacity or nocturnal polyuria; however, most often the cause is multifactorial. Disorders of circadian rhythm regulation are known to occur with sleep disturbances in PD may also contribute to nocturia.

METHODS AND RESULTS

In this review, an overview of the assessment and management of nocturia in patients with PD is presented. History taking, medication review, and a bladder diary form the cornerstone of the evaluation. Urinalysis, ultrasonography, and urodynamic studies help to assess the cause for lower urinary tract symptoms and exclude concomitant pathologies, such as bladder outlet obstruction. Antimuscarinic medications are the first-line treatment for the overactive bladder; however, caution is needed when using these medications in individuals predisposed to cognitive impairment. Desmopressin is effective for managing nocturnal polyuria.

CONCLUSIONS

An individualized approach is recommended to optimize the management of nocturia in PD.

Review

Nocturia is defined as the nocturnal frequency of one or more voiding episodes per night. It increases with aging and has an impact on sleep quality and the risks of falling and mortality. Nocturia disorder involves nighttime frequency, nocturnal polyuria, and nocturnal enuresis. In older adults with nocturia disorder, multiple factors could contribute to nocturia severity and characteristics, including poor sleep quality, lower urinary tract dysfunction, and excessive fluid output. Several nonurological medical diseases have been found to result in nocturia, such as hypertension, congestive heart failure, chronic kidney disease, chronic obstructive pulmonary disease, metabolic syndrome, and diabetes. Urological and medical assessments should be performed to diagnose nocturia disorder. A frequency volume chart to evaluate the nocturnal polyuria index, functional bladder capacity, and urodynamic study can reveal the presence of nocturnal polyuria and lower urinary tract dysfunction. Treatment should be based on multiple nocturia etiologies, and a combination of multiple therapies for individual pathophysiology will achieve a better treatment outcome.
