    OBJECTIVES: To examine the cross-sectional relationship of age, urinary and depressive symptoms and partner status on pain intensity and quality of life (QoL) in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

    PATIENTS AND METHODS: In all, 463 men enrolled in the National Institutes of Health (NIH) Chronic Prostatitis Cohort Study from seven clinical centres (six in the USA and one in Canada) reported baseline screening symptoms using the NIH Chronic Prostatitis Symptom Index ...

    OBJECTIVES: To determine the prevalence and importance of pain/discomfort on ejaculation (prostatitis-like symptom) in men with lower urinary tract symptoms (LUTS) diagnosed with clinical benign prostatic hyperplasia (BPH).

    PATIENTS AND METHODS: Baseline data from 5096 men reporting LUTS suggestive of BPH, and enrolled in the ALF-ONE study by general practitioners and urologists in Europe, Asia, Latin America, the Middle East and Canada, were analysed to determine the prevalence and ...

    OBJECTIVE: • To examine how the introduction of medical therapy for symptomatic benign prostatic hyperplasia (BPH) might have changed the indications, patient characteristics and outcomes in men undergoing transurethral resection of the prostate (TURP) over two decades (1988-2008).

    PATIENTS AND METHODS: • All patients who underwent TURP for symptomatic BPH in a geographically defined area at our institution in 1988 (before the introduction of medical therapy for BPH), 1998 (when medical ...

    PURPOSE: We characterized and compared the impact of clinical phenotypic associations between interstitial cystitis/painful bladder syndrome and controls in relation to potentially related conditions, particularly irritable bowel syndrome, fibromyalgia and chronic fatigue syndrome.

    MATERIALS AND METHODS: Female patients with interstitial cystitis/painful bladder syndrome and controls with no interstitial cystitis/painful bladder syndrome completed a biopsychosocial phenotyping ...

    OBJECTIVES: To perform a prospective, placebo-controlled study to examine the long-term efficacy of alfuzosin compared with placebo and standard therapy in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), because alpha-blockers have been suggested for the treatment of CP/CPPS.

    METHODS: One hundred twenty consecutive men diagnosed with CP/CPPS were prospectively screened and then asked to participate in a prostatitis treatment trial. Patients who agreed to be ...

    BACKGROUND: The current study was performed to evaluate whether baseline acute and chronic prostate inflammation among men with an initial negative biopsy for prostate cancer (PCa) increased the risk of subsequent PCa detection in a clinical trial with systematic biopsies.

    METHODS: A retrospective analysis was performed of 6238 men aged 50 years to 75 years with prostate-specific antigen levels between 2.5 ng/mL and 10 ng/mL and a prior negative biopsy in the REduction by DUtasteride of ...

    PURPOSE: We examine whether leukocytes and bacteria correlate with symptom severity in men with chronic prostatitis/chronic pelvic pain syndrome.

    MATERIALS AND METHODS: All 488 men screened into the National Institutes of Health Chronic Prostatitis Cohort Study before close of recruitment on August 22, 2001 were selected for analysis. The National Institutes of Health Chronic Prostatitis Symptom Index, including subscores, were used to measure symptoms. Urethral inflammation was defined ...

    PURPOSE: Identifying Hunner lesions in patients with interstitial cystitis/bladder pain syndrome presents an opportunity for objective classification into Hunner lesion interstitial cystitis/bladder pain syndrome (classic interstitial cystitis) and nonHunner lesion bladder pain syndrome. While currently the former diagnosis requires cystoscopy, limited data suggest that these subtypes can be distinguished without endoscopy based on the degree of bladder focused centricity and the ...

    PURPOSE: We determine the effects of treatment with rofecoxib and placebo in patients with chronic prostatitis.

    MATERIALS AND METHODS: Patients diagnosed with chronic nonbacterial prostatitis were randomized to 6 weeks of 25 or 50 mg., rofecoxib or placebo in a double-blind multicenter study with a 1-week run in of placebo. End points included the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (average pain score item 4 primary end point), and patient global ...

    CONTEXT: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is common, but trial evidence is conflicting and therapeutic options are controversial.

    OBJECTIVE: To conduct a systematic review and network meta-analysis comparing mean symptom scores and treatment response among α-blockers, antibiotics, anti-inflammatory drugs, other active drugs (phytotherapy, glycosaminoglycans, finasteride, and neuromodulators), and placebo.

    DATA SOURCES: We searched MEDLINE from 1949 and EMBASE ...

    BACKGROUND: The assessment of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in everyday practice and clinical studies relies on National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores for symptom appraisal, inclusion criteria for clinical trials, follow-up, and response evaluation.

    OBJECTIVE: We investigated multiple databases of CP/CPPS patients to determine the prevalence and impact of pain locations and types to improve our strategy ...

    Study Type - Therapy (systematic review) Level of Evidence 1a. What's known on the subject? and What does the study add? Individual clinical trials evaluating antibiotics, anti-inflammatories and α-blockers for the treatment of chronic prostatitis/chronic pelvic pain syndrome have shown only modest or even no benefits for patients compared with placebo, yet we continue to use these agents in selected patients with some success in clinical practice. This network meta-analysis of current ...

    OBJECTIVES: To propose a clinical phenotype system (urinary, psychosocial, organ specific, infection, neurologic/systemic, and tenderness [UPOINT]) to classify patients with urologic pelvic pain to help understand the etiology and guide therapy. We wished to validate this system in men with chronic pelvic pain syndrome (CPPS). CPPS is a heterogeneous syndrome with a variable treatment response.

    METHODS: A total of 90 men with CPPS were retrospectively classified in each domain of our ...

    OBJECTIVES: To study the association of sexual dysfunction with quality of life (QOL) while simultaneously examining the shared influence of empirically supported variables that are also associated with diminished interstitial cystitis/painful bladder syndrome (IC/PBS) QOL (ie, pain, catastrophizing, depression). Previous research has indicated that sexual dysfunction is prevalent, bothersome, and an important predictor of diminished QOL in patients with IC/PBS. However, the deleterious ...
