Male Urinary Incontinence: Prevalence, Risk Factors, and Preventive Interventions

Systematic Review

Robert L KaneTimothy J WiltRyan PingJean F WymanTatyana A Shamliyan

Urinary incontinence (UI) in community-dwelling men affects quality of lifeand increases the risk of institutionalization. Observational studies and randomized,controlled trials published in English from 1990 to November 2007on the epidemiology and prevention of UI were identified in several databasesto abstract rates and adjusted odds ratios (OR) of incontinence, calculateabsolute risk difference (ARD) after clinical interventions, and synthesizeevidence with random-effects models. Of 1083 articles identified, 126 wereeligible for analysis. Pooled prevalence of UI increased with age to 21% to32% in elderly men. Poor general health, comorbidities, severe physicallimitations, cognitive impairment, stroke (pooled OR 1.54; 95% confidenceinterval [CI], 1.14-2.1), urinary tract infections (pooled OR 3.49; 95%CI, 2.33-5.23), prostate diseases, and diabetes (pooled OR 1.36; 95% CI,1.14-1.61) were associated with UI. Treatment with tolterodine alone (ARD0.17; 95% CI, 0.02-0.32) or combined with tamsulosin (ARD 0.17; 95% CI,0.08-0.25) resulted in greater self-reported benefit compared with placebo.Radical prostatectomy or radiotherapy for prostate cancer compared withwatchful waiting increased UI. Short-term prevention of UI with pelvic floormuscle rehabilitation after prostatectomy was not consistently seen acrossrandomized, controlled trials. The prevalence of incontinence increased with ageand functional dependency. Stroke, diabetes, poor general health, radiation, andsurgery for prostate cancer were associated with UI in community-dwellingmen. Men reported overall benefit from drug treatments. Limited evidence ofpreventive effects of pelvic floor rehabilitation requires future investigation.[Rev Urol. 2009;11(3):145-165 doi:10.3909/riu0416]© 2009 MedReviews, LLC

The prevalence of nocturia in patients with multiple sclerosis (MS) is high, ranging from 20.9% to 48.8% in this population. Its underlying pathophysiology is complex and different from the non-neurogenic population. In the MS population, the pathophysiology may involve neurogenic lower urinary tract dysfunction (NLUTD) such as detrusor overactivity (NDO), detrusor-sphincter dyssynergia, or detrusor underactivity resulting in reduced bladder capacity. Nocturnal polyuria is also a significant contributor to the pathogenesis of nocturia in MS patients and may be the result of specific mechanisms such as nocturnal hypertension through autonomic cardiovascular dysfunction or lack of diurnal variation of antidiuretic hormone production (ADH) due to demyelinating lesions of the spinal cord. Nocturia might be particularly burdensome in MS patients by contributing to fatigue, a common and highly debilitating symptom in this population. There is likely a complex and multidirectional relationship between nocturia, other sleep disorders, and fatigue in the MS population that has yet to be explored. The assessment of nocturia in MS should rely upon a thorough history and physical examination. Urinalysis should be done to rule out urinary tract infection, a frequency-volume chart might help elucidating the underlying mechanisms, and post-void residual volume may be of interest to screen for urinary retention that could be asymptomatic in MS patients. Other tests such as urodynamics or polysomnography are indicated in selected patients. The treatment should be tailored to the underlying cause. The first steps involve behavioral interventions and treatment of cofactors. When possible, the predominant mechanism should be addressed first. In case of predominant NDO, antimuscarinics and beta-3 agonists should be offered as a first-line treatment and intradetrusor injections of botulinum toxin as a second-line treatment. In cases of incomplete bladder emptying, clean-intermittent self-catheterization is often used as part of multiple other interventions. In cases of nocturnal polyuria, desmopressin may be offered, inclusive of use of newer formulations (desmopressin acetate nasal spray, desmopressin orally disintegrated tablet) in countries where they are approved.

The Effect of Local Antibiogram–based Augmented Antibiotic Prophylaxis on Infection-related Complications Following Prostate Biopsy

Original Research

Neal D ShoreJeffrey A ScottEdward M SchaefferRaoul S ConcepcionGary M KirshDeepak A Kapoor

Given the number of prostate biopsies performed annually in the United States and associated infectious events as a result, we sought to determine if implementation of a standardized biopsy protocol utilizing antibiotic prophylaxis based on locally derived antibiograms would result in a decrease, relative to a contemporary control population, in the incidence of infection-related complications among community-based practices. A total of nine member groups of LUGPA participated in both a retrospective review and a prospective study of infection-related complications following prostate biopsy. Historic infectious complications, defined as chills/rigor, temperature higher than 101 °F, or documented positive blood or urine cultures, were self-reported by a retrospective review of patients undergoing prostate biopsy under the practice’s current protocol in the year prior to the study. The prospective phase of the study required each group to develop a locally derived augmented prophylaxis regimen (>2 antibiotics) based on local antibiograms. After implementation, the practices enrolled patients undergoing prostate biopsy over an 8-week period. Monitoring for infection-related complication took place over the ensuing 3 weeks post-biopsy. Seven hundred fifty-nine patients over nine practices were enrolled into the study utilizing the augmented locally determined prophylaxis protocol. There was a 53% reduction in the incidence of infection-related complication, relative to the historical rate. By developing a standardized biopsy protocol with specific emphasis on incorporating an augmented antibiotic prophylactic regimen based upon local antibiograms, we were able to demonstrate in a prospective trial across nine geographically distinct community practices a significant reduction in the incidence of infection-related complications.

Use of the 4Kscore Test to Predict the Risk of Aggressive Prostate Cancer Prior to Prostate Biopsy: Overall Cost Savings and Improved Quality of Care to the US Healthcare System

Health Economics

Stephen ZappalaVincent LinderYan DongJeffrey D Voigt

The 4Kscore® Test (BioReference Laboratories, Elmwood Park, NJ) is a blood test that accurately determines the risk of aggressive prostate cancer and significantly reduces prostate biopsies and associated overdiagnosis and overtreatment of indolent cancer. A budget impact model was developed to test the hypothesis that the 4Kscore Test can improve quality of care and deliver cost savings for patients who are suspected of having prostate cancer and would otherwise undergo prostate biopsy under the current standard of care (SOC) in the United States. The direct costs (diagnosis plus treatment) utilized in the model are based on Medicare payment data and were calculated over a 1-year time horizon. The model compares SOC, in which all patients have prostate biopsy, to a “4Kscore strategy,” in which the 4Kscore Test is used to guide the decision to biopsy the prostate. A set of one-way sensitivity analyses was conducted to examine the robustness of the findings. Savings of more than $169 million (15.6% of total SOC costs) were realized in the 4Kscore strategy versus SOC ($917 M versus $1,086 M, respectively) in a cohort of 100,000 patients. Sensitivity analyses demonstrated that the findings are robust. Most cost savings for the 4Kscore strategy were realized in patients who, when managed by SOC, are found to have no prostate cancer or Gleason score 6 pathology. The patients with Gleason score 6 exhibited the greatest benefits from the 4Kscore strategy, avoiding both an unnecessary prostate biopsy and subsequent overtreatment. The 4Kscore Test was shown to significantly reduce costs to the healthcare system while improving patients’ quality of care. Providers and their patients suspected of having prostate cancer should consider using the 4Kscore Test prior to proceeding with prostate biopsy.

Current Concepts in Ejaculatory Dysfunction

Advances in Alpha-Blocker Therapy in the Management of Urological Disorders

Wayne JG HellstromJeffrey P Wolters

Although erectile dysfunction has recently become the most well-known aspect of male sexual dysfunction, the most prevalent male sexual disorders are ejaculatory dysfunctions. Ejaculatory disorders are divided into 4 categories: premature ejaculation (PE), delayed ejaculation, retrograde ejaculation, and anejaculation/anorgasmia. Pharmacologic treatment for certain ejaculatory disorders exists, for example the off-label use of selective serotonin reuptake inhibitors for PE. Unfortunately, the other ejaculatory disorders are less studied and not as well understood. This review revisits the physiology of the normal ejaculatory response, specifically explores the mechanisms of anejaculation, and presents emerging data. The neurophysiology of the ejaculatory reflex is complex, making classification of the role of individual neurotransmitters extremely difficult. However, recent research has elucidated more about the role of serotonin and dopamine at the central level in the physiology of both arousal and orgasm. Other recent studies that look at differing pharmacokinetic profiles and binding affinities of the 1-antagonists serve as an indication of the centrally mediated role of ejaculation and orgasm. As our understanding of the interaction between central and peripheral modulations and regulation of the process of ejaculation increases, the probability of developing centrally acting pharmaceutical agents for the treatment of sexual dysfunction approaches reality.

There is significant concern regarding prostate cancer screening because of the potential for overdiagnosis and overtreatment of men who are discovered to have abnormal prostate specific antigen (PSA) levels and/or digital rectal examination (DRE) results. The 4Kscore® Test (OPKO Diagnostics, LLC) is a blood test that utilizes four kallikrein levels plus clinical information in an algorithm to calculate an individual’s percentage risk (< 1% to > 95%) for aggressive prostate cancer (Gleason score ≥ 7) on prostate biopsy. The 4Kscore Test, as a follow-up test after abnormal PSA and/or DRE test results, has been shown to improve the specificity for predicting the risk of aggressive prostate cancer and reduce unnecessary prostate biopsies. A clinical utility study was conducted to assess the influence of the 4Kscore Test on the decision to perform prostate biopsies in men referred to urologists for abnormal PSA and/or DRE results. The study population included 611 patients seen by 35 academic and community urologists in the United States. Urologists ordered the 4Kscore Test as part of their assessment of men referred for abnormal PSA and/or DRE test results. Results for the patients were stratified into low risk (< 7.5%), intermediate risk (7.5%-19.9%), and high risk (≥ 20%) for aggressive prostate cancer. The 4Kscore Test results influenced biopsy decisions in 88.7% of the men. Performing the 4Kscore Test resulted in a 64.6% reduction in prostate biopsies in patients; the actual percentage of cases not proceeding to biopsy were 94.0%, 52.9%, and 19.0% for men who had low-, intermediate-, and high-risk 4Kscore Test results, respectively. A higher 4Kscore Test was associated with greater likelihood of having a prostate biopsy (P < 0.001). Among the 171 patients who had a biopsy, the 4Kscore risk category is strongly associated with biopsy pathology. The 4Kscore Test, as a follow-up test for an abnormal PSA and/or DRE results, significantly influenced the physician and patient shared decision in clinical practice, which led to a reduction in prostate biopsies while increasing the probability of detecting aggressive cancer.
