Chronic prostatitis/chronic pelvic pain syndrome

In the 20th century, the term "prostatitis" traditionally referred to inflammation in the prostate, often attributed to infection. Prostatitis in this century usually refers to a chronic pain syndrome for which the presence of inflammation and involvement of the prostate are not always certain. This article discusses chronic prostatitis/chronic pelvic pain syndrome and the various factors associated with diagnosis and treatment.     

Mechanisms in prostatitis/chronic pelvic pain syndrome

PURPOSE: We reviewed the current literature on mechanisms involved in the pathogenesis of prostatitis/chronic pelvic pain syndrome (CPPS). MATERIALS AND METHODS: A literature review for the years 1966 to 2003 was performed using the MEDLINE database of the United States National Library of Medicine. RESULTS: National Institutes of Health categories I and II prostatitis result from identifiable prostatic infections, whereas patients with category IV are asymptomatic. The majority of symptomatic cases are category III or chronic prostatitis (CP)/CPPS. The etiology of CP/CPPS is unknown. The traditional marker of inflammation, namely white blood cells in prostatic fluids, does not correlate with the predominant symptom of pelvic pain. An imbalance toward increased proinflammatory and decreased anti-inflammatory cytokines has been implicated and a few studies have shown some correlation of this with pelvic pain. The imbalance in some men may result from polymorphisms at the cytokine loci. An autoimmune process may be involved and experimental evidence indicates that this can be under hormonal influence. Recent findings include possible defects in the androgen receptor. The prostate may not even be the source of the symptoms. Pelvic pain also correlates with the neurotrophin nerve growth factor implicated in neurogenic inflammation and central sensitization. Finally, psychological stress may produce measurable biochemical changes and influence the other processes. The role of normal prostatic bacterial flora in inciting the inflammatory response has also been reconsidered. CONCLUSIONS: The symptoms of CP/CPPS appear to result from an interplay between psychological factors and dysfunction in the immune, neurological and endocrine systems.     

Acupuncture for chronic prostatitis/ chronic pelvic pain syndrome

Chronic prostatitis/chronic pelvic pain syndrome (CP/ CPPS) is prevalent in urological practice and has a significant impact on quality of life. Standard therapies often fail to achieve sustainable amelioration of symptoms. This article attempts to show that neuromodulatory treatment in the form of electroacupuncture can be a minimally invasive and effective treatment for CP/CPPS that is refractory to standard therapies. This neuromodulatory therapy lends support to the hypothesis that the end stage of CP/CPPS may be a neuropathic pain syndrome.     

Quercetin for chronic prostatitis/chronic pelvic pain syndrome

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition with a heterogeneous origin that responds best to multimodal therapy. The bioflavonoid quercetin has antioxidant and antiinflammatory effects that have proven useful for treating this condition. Using the clinical phenotype system UPOINT, quercetin can be helpful for those with organ-specific complaints (bladder or prostate) and pelvic floor spasm. This article discusses the current understanding of CP/CPPS and how treatment with quercetin can be used alone or as part of multimodal therapy.     

Sexual dysfunction in chronic prostatitis/chronic pelvic pain syndrome

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), or NIH category III prostatitis, is a common clinical syndrome characterized by genital/pelvic pain and lower urinary tract symptoms in the absence of urinary tract infection. There is also growing recognition of the association of sexual dysfunction with CP/CPPS including erectile dysfunction, ejaculatory pain, and premature ejaculation. In this review, we discuss the association between CP/CPPS and sexual dysfunction, potential mechanisms for sexual dysfunction, and treatment strategies for erectile dysfunction in CP/CPPS.     

Controversies in chronic abacterial prostatitis/pelvic pain syndrome

Chronic abacterial prostatitis (or prostatitis Category III according to the National Institutes of Health terminology) is subject to re-evaluation. Organizations such as the International Continence Society, the International Association for the Study of Pain and the European Association of Urology have been involved in a continuous endeavour to design a more accurate taxonomy system. The term prostate pain syndrome (PPS), as a subcategory of chronic pelvic pain syndromes, has recently been suggested as the most relevant. This condition is common, very bothersome and enigmatic. Symptoms are usually prolonged and, generally speaking, treatment results are unsatisfactory. During the last decade, research has focused on the distress caused by the condition, but although our knowledge has certainly increased there have been no real breakthroughs; controversies and many unanswered questions remain. Examples of pertinent issues are as follows: the criteria that need to be fulfilled for a diagnosis; the significance or lack of significance of leucocytes in expressed prostatic secretion; and the association between erectile dysfunction and PPS. The fundamental question remains: is the prostate really involved in the majority of men with PPS? This article focuses on some of the controversies.     

Etiologic theories of chronic prostatitis/chronic pelvic pain syndrome

The etiology of chronic prostatitis/chronic pelvic pain syndrome is unknown. Whereas infection causes category I and II prostatitis, the evidence for an ongoing infection in category III patients is lacking. Immunologic, neurologic, and psychologic factors likely play a role in the development and maintenance of symptoms in these men. The traditional concept of pain as a simple response to a noxious stimulus has some merit, but modern research indicates that the response is much more complex, and we must look at a patient’s physiology and psychology to be able to interpret each individual’s pain response. It is some advance in the field to realize that we probably need to look beyond the prostate and address the entire biopsychosocial problem to be able to offer successful treatment to these men.     

Multimodal therapy for chronic prostatitis/chronic pelvic pain syndrome

Category III chronic prostatitis/chronic pelvic pain syndrome is a syndrome rather than a specific disease and the cause can be multifactorial. In clinical practice, monotherapy often has proven ineffective. Multimodal therapy, which sequentially or simultaneously can address infection, inflammation, and neuromuscular spasm appears to have the greatest potential for symptom improvement, especially in patients with longstanding symptoms.     

Therapeutic options for chronic prostatitis/chronic pelvic pain syndrome

Chronic prostatitis/chronic pelvic pain syndrome continues to pose a treatment challenge for urologists. Most commonly prescribed medications, such as antibiotics, α-blockers, androgen inhibitors, and anti-inflammatory agents, have been shown to help some patients. However, the efficacy and durability of such treatments lack consistency among men suffering from this disorder. The rationale for such treatments is described in this article, along with possible explanations for the apparent shortcomings. Also included is a brief summary of alternative therapies, which are growing in popularity among patients and gaining acceptance in our medical communities.     

Seminal fluid analysis in chronic prostatitis/chronic pelvic pain syndrome

Prostatitis is a common cause of morbidity among adult men. There are more than 2,000,000 doctor visits per year in the United States, approximately half to urologists (Collins et al., 1998, J Urol 159:1224; Roberts et al., 1998, Urology 51:578; Krieger et al., 2003, Urology). The problem is that very few patients have obvious infections, or functional or structural abnormalities. The aim of this study is to examine our experience with seminal fluid analysis in this patient population, and to outline the potential utility of this examination in patient evaluation.     

Leukocytes and bacteria in men with chronic prostatitis/chronic pelvic pain syndrome compared to asymptomatic controls

PURPOSE: Chronic prostatitis has been traditionally characterized by inflammation and/or infection of the prostate gland, objectively categorized by white blood cells and cultured bacteria in prostate specific specimens. We compared leukocyte counts and localization rates for bacterial cultures of segmented urine samples (VB1, VB2, VB3), expressed prostatic secretion (EPS) and semen in men diagnosed with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) to men without pelvic pain (controls). MATERIALS AND METHODS: A total of 463 men enrolled in the National Institutes of Health Chronic Prostatitis Cohort study and 121 age matched men without urinary symptoms had leukocyte counts performed and 5-day bacterial cultures on specimens obtained from a standard 4-glass test (VB1, VB2, EPS, VB3) and semen. All risk factor comparisons between case and control analyses were tested using generalized Mantel-Haenszel methods, and multivariable models were developed using logistic regression methods, adjusting for clustering by clinical center within both methods. RESULTS: Men with CP/CPPS had statistically higher leukocyte counts in all segmented urine samples and EPS, but not in semen compared to asymptomatic control men. However, the control population also had a high prevalence of leukocytes. Of the men with CP/CPPS 50% and 32% had 5 or more, or 10 or more white blood cells (WBCs) per high power field, respectively, in EPS compared to 40% and 20% of the control population. Similarly, 32% and 14% of the patients with CP/CPPS had 5 or more, or 10 or more WBCs per high power field in VB3 compared to 19% and 11% in the control population. Localization of uropathogenic bacteria in EPS, VB3 and/or semen was similar in men with CP/CPPS (8.0%) and asymptomatic men (8.3%). CONCLUSIONS: Men with CP/CPPS have significantly higher leukocyte counts in all segmented urine samples and EPS but not in semen as compared to controls. There is no difference in rates of localization of bacterial cultures for men with CP/CPPS compared to control men. The high prevalence of WBCs and positive bacterial cultures in the asymptomatic control population raises questions about the clinical usefulness of the standard 4-glass test as a diagnostic tool in men with CP/CPPS.     

Acute bacterial prostatitis and chronic prostatitis/chronic pelvic pain syndrome: andrological implications

There is a consensus on the diagnostic management of bacterial prostatitis (acute and chronic). In chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) the diagnostic approach remains unclear, because inflammatory and noninflammatory CP/CPPS might be one entity with varying findings over time. The WHO definition of male accessory gland infection does not differentiate between prostatitis, epididymitis, and other inflammatory alterations of the urethral compartment. The definition therefore cannot be further accepted as a rational tool for the diagnosis of prostatitis and related diseases in urological andrology. Therapy in infectious prostatitis is standardised and antibiotics are the primary agents. Andrological implications are well defined, side-effects are minimal. CP/CPPS therapy has the goal to reduce pelvic pain. However, treatment regimens are not as standardised. Andrological side-effects are well defined and mainly due to the functional background of these agents.     

慢性前列腺炎/慢性骨盆疼痛综合征药物治疗进展

慢性前列腺炎(chronic prostatitis.CP)是泌尿外科门诊中最常见的一种疾病,流行病学调查显示:CP在男性人群发病率高达2.5%～16.0%,慢性前列腺炎/慢性骨盆疼痛综合征(CP/CPPS)是CP中最常见也是疗效最差的类型,其发病机制目前不是很清楚.治疗没有规范和标准.本文就近年来国内外有关CWCPPS药物治疗方面的新进展作一综述,并探讨目前治疗所面临的主要问题及可能原因.     

The impact of chronic prostatitis/chronic pelvic pain syndrome on patients

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition, affecting men of all ages. Since mortality and serious complications are extremely uncommon, CP/CPPS is primarily a quality-of-life disease, and, therefore, the patient's perspective is of paramount importance. As with other non-life threatening diseases, the goal of treatment is to maximize quality not quantity of life. Scientifically validated methods to measure patients' health related quality of life have been applied in other urological diseases such as benign prostatic hyperplasia and interstitial cystitis; the same process is now underway in the study of CP/CPPS. Recent studies have shown that CP/CPPS takes a substantial toll on physical and mental health. In addition to examining the health related quality of life of patients with CP/CPPS, future studies should address additional patient-centered outcomes, such as satisfaction with care and the economic burden of the illness, in order to allow a more comprehensive understanding of the impact of this condition on patients.
