Is the Bladder a Reliable Witness for Predicting Detrusor Overactivity

PURPOSE We determined how well the symptoms of OAB syndrome correlate with urodynamic DO using International Continence Society definitions. MATERIALS AND METHODS The study included adult males and females 18 years or older who attended a tertiary referral center for urodynamics from February 2002 to February 2004. Patients were selected based on OAB syndrome symptoms (urgency, urgency urinary incontinence and frequency). The percent of patients who had symptoms alone or in combination and DO was calculated. RESULTS There was a better correlation in results between OAB symptoms and the urodynamic diagnosis of DO in men than in women. Of men 69% and 44% of women with urgency (OAB dry) had DO, while 90% of men and 58% of women with urgency and urgency urinary incontinence (OAB wet) had DO. Stress urinary incontinence seems to have accounted for the decreased rates in women since 87% of women with urgency urinary incontinence also had the symptom of stress urinary incontinence. The ICS definition does not specify what constitutes abnormal voiding frequency. Analysis of results showed that increasing voiding frequency did not have any effect on increasing the accuracy of diagnosis of DO except in women with 10 or more daytime micturition episodes. CONCLUSIONS The bladder is a better and more reliable witness in men than in women with a greater correlation between OAB symptoms and urodynamic DO, more so in the OAB wet than in OAB dry patients.

Pharmacological treatment of overactive bladder: report from the International Consultation on Incontinence

Purpose of review Treatment options for the overactive bladder were recently discussed at the 4th International Consultation on Incontinence (ICI) held in Paris, 5–8 July 2008. This article will overview current thoughts on the pharmacological and clinical basis for the different classes of drugs currently used for the treatment of lower urinary tract symptoms/overactive bladder syndrome/and detrusor overactivity. Individual drugs are not discussed in detail; particular consideration is given to therapeutic aspects of the management of the elderly patient. Recent findings An extensive literature review confirms the rationale for using antimuscarinic drugs, and that the currently used drugs are efficacius with an acceptable tolerability and safety. In patients resistant to antimuscarinics, botulinum toxin may be an alternative – the vanilloids resiniferatoxin and capsaicin have very limited use. New therapeutic options with positive proof-of-concept studies, but with limited clinical experience, are β3 adrenoceptor agonists and phosphodiesterase type 5 inhibitors. Positive signals have been found for other classes of drugs (e.g., gonadotropin-releasing hormone antagonists, neurokinin receptor-1 antagonists), but available information is not sufficient for proper assessment. Summary Antimuscarinic drugs remain the first-line treatment of the overactive bladder and a favorable efficacy/tolerability-safety ratio can be confirmed. Promising new alternatives are emerging and future controlled studies will decide their place in the therapeutic arsenal.

How should patients with an overactive bladder manipulate their fluid intake

Drug treatment of overactive bladder: efficacy, cost and quality-of-life considerations.

Overactive bladder (OAB) syndrome has been recognised by the International Continence Society as an important symptom syndrome that affects millions of people worldwide. Quality of life is affected in most people with OAB; however, the aetiology is unknown. Some researchers suggest that it is because of a damage to central inhibitory pathways or sensitisation of peripheral afferent terminals in the bladder, others suggest that it is a bladder muscle problem; the reality is probably a spectrum encompassing these two main explanations. Therefore, treatment is difficult and is aimed at alleviating symptoms (being those of urgency, with or without urge incontinence, usually with frequency and nocturia) rather than treating the cause. A thorough patient history and physical examination are required to establish a possible diagnosis. Frequency/volume charts form an important aid to the diagnosis. Once a presumptive diagnosis is made, conservative management forms the first line of treatment and includes lifestyle modifications, bladder training and pelvic floor exercises. If this fails, pharmacotherapy, in the form of anticholinergic drugs, is initiated.There are many antimuscarinic drugs, for example oxybutynin, tolterodine and trospium chloride. Each has a different specificity to bladder muscarinic receptors, thus producing different adverse effect profiles (e.g. dry mouth, blurred vision and constipation). Different individuals experience these adverse effects to different extents. New anticholinergic drugs, that have undergone phase III trials and are more specific to the muscarinic M3 human bladder receptor, are being introduced to the market in 2004 (e.g. solifenacin succinate and darifenacin). In addition to adverse effect profile, cost and improvement in quality of life are important factors in choosing treatment. Further research is being conducted on other types of drugs and different administration modalities, for example intravesical botulinum toxin A. Sacral nerve neuromodulation is emerging as a potential treatment, but if all treatments fail then surgery is the last resort.

Overactive bladder: an update.

Purpose of review Overactive bladder is an important lower urinary tract syndrome that negatively affects the quality of life of millions of people worldwide. Both sexes and all age groups may be affected; therefore many specialists, including urologists, gynaecologists, geriatricians, paediatricians, physiotherapists and continence advisors, are involved in the management of patients with overactive bladder. Recent findings There is ongoing research, both basic science and clinical trials, to establish the cause of overactive bladder and to determine the best method of managing patients who suffer from this syndrome. New theories and modified definitions of overactive bladder have been proposed, structured evidence-based management guidelines have been established, more prevalence studies have been conducted and new treatment strategies have emerged. Summary Overactive bladder is now recognized as a chronic debilitating condition that costs millions of dollars. With an ageing population these costs will increase, and it is necessary that health systems around the world recognize this. Further research into the basic science of the condition is required to identify the true cause of overactive bladder, allowing new targeted treatments to be established.

Thinking beyond the bladder: antidiuretic treatment of nocturia

Nocturia is a bothersome and highly prevalent urological condition characterised by the need to wake to void at night. Contrary to popular misconception, nocturia is equally common in men and women, and although its prevalence increases with age, a significant proportion of younger people are also affected. Nocturia leads to repeated fragmentation of sleep and consequently to a serious decline in daytime functioning and in overall quality of life and health. As such, its impact should not be underestimated by clinicians. Traditionally, nocturia has been regarded as a symptom of benign prostatic enlargement and/or overactive bladder syndrome, with treatment therefore directed towards increasing the capacity of the bladder to hold urine. Such treatments have proven largely ineffective in many patients, likely because nocturnal polyuria (NP), a condition that results in overproduction of urine at night, has been found to be present in the majority of nocturia patients. As such, the traditional belief that nocturia is attributable to some other underlying pathological factors, is now being replaced by the acknowledgment that it can be a distinct clinical entity with specific pathogenesis. Frequency‐volume charts are an invaluable tool, recommended for routine use in clinical practice, to determine whether nocturia is a result of excessive urine production at night, or of small voided volumes (indicating bladder storage problems), or indeed a combination of these factors. Given the specific antidiuretic action of desmopressin, a synthetic analogue of the body’s own antidiuretic hormone, it should be considered as first‐line therapy for patients with nocturia where NP is present.

Nocturia think tank: Focus on nocturnal polyuria: ICI‐RS 2011

The following is a report of the proceedings of the Nocturia Think Tank sessions of the annual International Consultation on Incontinence‐Research Society, which took place June 13–15, 2011 in Bristol, UK. The report is organized into sections pertaining to the main topics of discussions having occurred at that meeting, centering on the relationship of nocturnal polyuria (NP) and nocturia but also synthesizing more current evidence advancing our knowledge of the diagnosis and management of nocturia. This article is not meant to be a comprehensive review on the subject of nocturia, a number of which are available in the recent literature. All authors were physically present during, or in a preliminary session just prior to, the meeting in Bristol. Neurourol. Urodynam. 31:330–339, 2012.

An Overview of the Diagnosis and Treatment of Erectile Dysfunction

Epidemiological studies have demonstrated an age-stratified increase in the incidence and prevalence of erectile dysfunction (ED). There is a greater degree of openness today when discussing sexual matters and more information on the treatment of ED is available to the public through the media. Quality-of-life issues are now a matter of great importance to the aging population. Men and their partners are no longer prepared to merely accept ED as a natural consequence of aging. The advent of a simple and effective oral therapy for ED has also indirectly fuelled the increase in treatment-seeking behaviour among men.Despite great strides in research into ED, our knowledge and understanding of the pathophysiological mechanisms is still in its infancy. As a result, we are able to treat only the symptom of ED rather than prevent it. Common diseases found in the population, such as diabetes mellitus and coronary artery disease appear to be risk factors for the development of ED. Therefore, physicians need to identify any underlying co-existing organic diseases in their patients presenting with ED.Whenever possible, patients are encouraged to attend their consultation sessions with their partners because ED is a condition affecting ‘the couple’ and not just the man. Psychogenic aspects of ED should also be explored during the consultation. Efforts need to be made to uncover and address the presence of any psychological stressors, if necessary with the help of a psychosexual therapist.The first-line treatment of ED is oral phosphodiesterase-5 inhibitors. For those who do not respond to oral therapy, there is no defined ‘step-ladder’ escalation in alternative therapy. It is up to the physician to discuss the options with the patient or couple and reach a decision based on their preference.

Nocturia research: current status and future perspectives.

This review summarizes the status of nocturia research, highlighting the conditions distinct nature, as well as areas where further studies are needed. Unlike other LUTS, nocturia has a specific and detrimental effect on the sleep period, and when ≥2 voids per night are experienced it is associated with various sequelae including reduced QoL and productivity, and increased morbidity and perhaps mortality. Many sources suggest that nocturia is associated with chronic medical illness, but little evidence demonstrates that successful treatment of these conditions results in normalization of nocturia, or that improvement in nocturia improves QoL and overall health. To date, management algorithms for LUTS have been based upon reasonable supposition and limited evidence, rather than controlled trials. Whilst a working clinical model is useful until conclusive research is available, a healthy scepticism should be maintained. It is likely that more than one contributory factor is responsible for nocturia, and management ought to better reflect this multifactorial pathophysiology. Indeed, traditional perspectives assuming nocturia to be part of the OAB or BPE symptom complex may have helped to propagate the misconception that therapy for these conditions is sufficient to improve nocturia. In reality, improvements in nocturia with anticholinergics, α‐blockers and/or 5‐α reductase inhibitors have been consistently disappointing. Antidiuretic therapy may represent a more tailored approach to management for many nocturia patients, given the high rates of nocturnal polyuria reported. Combination therapy may be required. Further high quality research on pathophysiology, management and patient‐reported outcomes with treatment is needed to augment existing limited data. Neurourol. Urodynam. 29:623–628, 2010.
