Recurrent vesicourethral anastomotic stenosis following treatment for prostate cancer: an effective endoscopic treatment using bipolar plasma button and triamcinolone. Int Urol Nephrol 2022; 54:1001-1008. [PMID: 35235110 DOI: 10.1007/s11255-022-03153-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 02/19/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE To evaluate the efficacy of deep bladder neck incision plus adjuvant Triamcinolone in the treatment of recurrent vesicourethral anastomotic stenosis following surgical treatment for prostate cancer. MATERIALS AND METHODS A retrospective review of patients undergoing bladder neck incision from 2013 to 2019 was conducted. Patients who had previously undergone surgical treatment for prostate cancer and had failed treatment for bladder neck contracture were included. RESULTS Twenty patients underwent deep bladder neck incision (BNI) with plasma button and adjuvant injection with a patency rate of 85%. Complete obliteration portended worst prognosis with 100% recurrence. CONCLUSIONS Deep BNI with triamcinolone is a minimally morbid alternative for treatment of refractory vesicourethral anastomotic contractures.

Genetic Polymorphisms of IFNG, IFNGR1, and Androgen Receptor and Chronic Prostatitis/Chronic Pelvic Pain Syndrome in a Chinese Han Population. DISEASE MARKERS 2021; 2021:2898336. [PMID: 34646402 PMCID: PMC8505099 DOI: 10.1155/2021/2898336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/22/2021] [Accepted: 09/11/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) refers to a common disorder with unclear etiology and unsatisfactory treatment, which reduces the male's quality of life. OBJECTIVE To examine the effects of genetic polymorphisms of IFNG, IFNGR1, and androgen receptor (AR) on CP/CPPS. METHODS The single nucleotide polymorphisms (SNPs) of IFNG, IFNGR1, and AR were genotyped with the improved multiplex ligation detection reaction. The GTEx, RegulomeDB, HaploReg, and 3DSNP databases were adopted to predict the regulatory functions of the genotyped SNPs. The correlation between SNPs and CP/CPPS was analyzed with the χ 2 test, logistic regression, and two genetic models (codominant and log-additive models). The nomogram was built to predict the risk of CP/CPPS occurrence. RESULTS On the whole, 130 CP/CPPS patients and 125 healthy controls were recruited in the study, and 18 SNPs of IFNG, IFNGR1, and AR were genotyped. The results of functional annotation indicated that the 18 genotyped SNPs might have regulatory effects in the whole blood. The rs144488434 was correlated with the elevated CP/CPPS risk (odds ratio (OR): 2.40, 95% confidence interval (CI): 1.12-5.13, χ 2 = 5.37, and P = 0.021) by the χ 2 test. In the built genetic models, rs10457655 was correlated with the elevated National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores (codominant model: GA/GG: crude mean difference (MD) = 0.98, 95% CI: -1.71-3.67 and AA/GG: crude MD = 9.10, 95% CI: 0.58-17.62, P = 0.10). In subgroup analysis, rs2069718 was correlated with the elevated CP/CPPS risk (log-additive model: crude OR = 2.18, 95% CI: 1.03-4.64, and P = 0.034) in patients ≥ 35 years. The nomogram integrating age, rs2069718, rs10457655, and rs144488434 showed good performance to predict the risk of CP/CPPS. CONCLUSIONS Genetic polymorphisms of IFNG, IFNGR1, and AR might act as the genetic factors for CP/CPPS susceptibility, which deserved further explorations.

Efficacy and safety evaluation of low-intensity extracorporeal shock wave therapy on prostatitis-like symptoms: An open-label, single-arm trial. Andrologia 2021; 54:e14260. [PMID: 34585431 DOI: 10.1111/and.14260] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 09/11/2021] [Accepted: 09/21/2021] [Indexed: 12/13/2022] Open
Abstract
The present work aims to evaluate the clinical efficacy and safety of low-intensity extracorporeal shock wave therapy (Li-ESWT) on patients with prostatitis-like symptoms (PLS). Patients with PLS were recruited and received four-week Li-ESWT (once per week), which was conducted at a frequency of 3 Hz with a preferred energy flow density of 0.25 mJ/mm2 . The scores of the National Institute of Health Chronic Prostatitis Symptoms Index (NIH-CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF-5), and Visual Analogue Scale (VAS) were recorded to assess the remission of disease in the 0, 1st, 2nd, 3rd, 4th, 5th, 8th and 16th weeks. A decrease of the NIH-CPSI score ≥6 was regarded as the effectiveness standard of Li-ESWT. Among 91 enrolled patients, the scores of all validated questionnaires presented significant improvements in the 4th week (p < .05) compared with that in baseline, except for IIEF-5. The treatment effective rates in the 1st, 2nd, 3rd, 4th, 5th, 8th and 16th weeks were 28.57%, 38.46%, 47.25%, 51.65%, 57.30%, 68.18% and 69.44%, respectively. No pronounced undesirable side effect has occurred. Li-ESWT is effective and safe in treating PLS. The efficacy can be maintained within three months.

Does weather trigger urologic chronic pelvic pain syndrome flares? A case-crossover analysis in the multidisciplinary approach to the study of the chronic pelvic pain research network. Neurourol Urodyn 2020; 39:1494-1504. [PMID: 32893408 DOI: 10.1002/nau.24381] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 04/19/2020] [Accepted: 04/21/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND To investigate whether meteorological factors (temperature, barometric pressure, relative humidity, ultraviolet index [UVI], and seasons) trigger flares in male and female urologic chronic pelvic pain patients. METHODS We assessed flare status every 2 weeks in our case-crossover study of flare triggers in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain 1-year longitudinal study. Flare symptoms, flare start date, and exposures in the 3 days preceding a flare or the date of questionnaire completion were assessed for the first three flares and at three randomly selected nonflare times. We linked these data to daily temperature, barometric pressure, relative humidity, and UVI values by participants' first 3 zip code digits. Values in the 3 days before and the day of a flare, as well as changes in these values, were compared to nonflare values by conditional logistic regression. Differences in flare rates by astronomical and growing seasons were investigated by Poisson regression in the full study population. RESULTS A total of 574 flare and 792 nonflare assessments (290 participants) were included in the case-crossover analysis, and 966 flare and 5389 nonflare (409 participants) were included in the full study analysis. Overall, no statistically significant associations were observed for daily weather, no patterns of associations were observed for weather changes, and no differences in flare rates were observed by season. CONCLUSIONS We found minimal evidence to suggest that weather triggers flares, although we cannot rule out the possibility that a small subset of patients is susceptible.

Research Trends in Agenda-setting for Climate Change Adaptation Policy in the Public Health Sector in Korea. J Prev Med Public Health 2020; 53:3-14. [PMID: 32023669 PMCID: PMC7002993 DOI: 10.3961/jpmph.19.326] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Accepted: 01/10/2020] [Indexed: 11/18/2022] Open
Abstract
Many studies have been conducted to assess the health effects of climate change in Korea. However, there has been a lack of consideration regarding how the results of these studies can be applied to relevant policies. The current study aims to examine research trends at the agenda-setting stage and to review future ways in which health-related adaptation to climate change can be addressed within national public health policy. A systematic review of previous studies of the health effects of climate change in Korea was conducted. Many studies have evaluated the effect of ambient temperature on health. A large number of studies have examined the effects on deaths and cardio-cerebrovascular diseases, but a limitation of these studies is that it is difficult to apply their findings to climate change adaptation policy in the health sector. Many infectious disease studies were also identified, but these mainly focused on malaria. Regarding climate change-related factors other than ambient temperature, studies of the health effects of these factors (with the exception of air pollution) are limited. In Korea, it can be concluded that studies conducted as part of the agenda-setting stage are insufficient, both because studies on the health effects of climate change have not ventured beyond defining the problem and because health adaptation to climate change has not been set as an important agenda item. In the future, the sharing and development of relevant databases is necessary. In addition, the priority of agenda items should be determined as part of a government initiative.

Association between ambient temperature and lower urinary tract symptoms: a community-based survey. Int Braz J Urol 2017; 42:521-30. [PMID: 27286116 PMCID: PMC4920570 DOI: 10.1590/s1677-5538.ibju.2015.0159] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2015] [Accepted: 08/10/2015] [Indexed: 12/11/2022] Open
Abstract
Purpose The aim of this study was to evaluate the individual change of International prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS) in each patient by temperature conditions. Materials and Methods The severity of lower urinary tract symptoms (LUTS) was explored using the IPSS and OABSS questionnaires that were completed by 2.486 subjects (923 males and 1.563 females) aged 60 years and older. Korea Meteorological Administration data was used to determine daily average temperature and daily temperature difference on the interview dates at each site. Results The mean IPSS and mean age for males was 13.45±8.24 and 75.03±6.20 years, respectively. The mean OABSS and mean age for females was 4.41±3.10 and 73.74±6.03years, respectively. Daily average temperature and daily temperature difference ranged from-3.4-28.3oC and 2.2-16.9oC, respectively. Age was a significantly risk factor for IPSS, OABSS, and QoL (P<0.001, <0.001, and 0.005, respectively). After multiple regression analysis, daily average temperatures did not show a statistically significant change in IPSS and OABSS. Only daily temperature differences were associated with male LUTS. Conclusions While LUTS could be worsened in low temperatures generally, IPSS and OABSS were not affected by daily average temperature conditions. Daily temperature differences may be more influential than daily average temperatures.

The mediation of interleukin-17 and chemokine ligand 2 in pelvic pain of experimental autoimmune prostatitis. Exp Ther Med 2017; 14:51-58. [PMID: 28672892 PMCID: PMC5488646 DOI: 10.3892/etm.2017.4448] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2016] [Accepted: 01/13/2017] [Indexed: 01/13/2023] Open
Abstract
The present study aimed to determine the expression and mediation of interleukin-17 (IL-17) and chemokine ligand 2 (CCL2) in a rat model with experimental autoimmune prostatitis (EAP). A total of 44 Sprague Dawley (SD) rats were used in the present study. Of these, a total of 20 two-month-old SD rats were randomly divided into a normal control (n=10) and a model group (EAP group, n=10). The remaining 24 two-month old SD rats were treated in the same way as EAP rats and subsequently randomly divided into a tacrolimus group (n=8), a celecoxib group (n=8) and a normal saline (NS) control group (n=8). Rats in the EAP and normal control groups underwent the Von Frey filaments behavioral test; rats in the tacrolimus, celecoxib and normal saline groups received a pain test following intervention treatment. Prostate tissues of SD rats in each group were harvested for reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis to observe the expression of IL-17 and CCL2. In the pain-reaction test, the occurrence of abnormal pain in the EAP group was significantly higher compared with the control group (P<0.001). The celecoxib group experienced a significant decrease in pain at day 10 compared with the NS group (P<0.01), while the decrease in pain experienced by the tacrolimus group was only significant at day 30 (P<0.001) and the pain experienced by the NS group decreased slightly over this same period. Results of RT-qPCR and western blot analysis indicated that, compared with the control group, the expression of IL-17 and CCL2 in the prostate tissue of EAP rats was significantly upregulated 50 days following modeling (P<0.05). On day 30 following intervention, the expression of IL-17 and CCL2 in the prostate of rats in the tacrolimus and celecoxib groups was significantly downregulated compared with the NS group (P<0.05). Therefore, the results of the current study demonstrate that IL-17 and CCL2 serve a vital role in the morbidity of the experimental autoimmune prostatitis and may also have a mediation effect on pelvic pain associated with chronic prostatitis.

Association Between Ambient Temperature and Lower Urinary Tract Symptoms: A Hospital-Based Cross-Sectional Analysis. Low Urin Tract Symptoms 2016; 10:38-44. [PMID: 27438480 DOI: 10.1111/luts.12138] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 04/03/2016] [Accepted: 04/10/2016] [Indexed: 01/02/2023]
Abstract
OBJECTIVES To date, there is no overall agreement as to risk of ambient temperature for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Thus, we focused on ambient temperature as an environmental factor affecting LUTS and attempted to explain the temperature differences in LUTS severity in cases in real clinical practice. METHODS This was a multicenter, cross-sectional survey. The study involved 1612 men aged 40 years and older who visited 23 university hospitals in 10 major areas in South Korea between September 2010 and December 2011. The participants who had good overall mental and physical health, and complaint of LUTS were included. Korea Meteorological Administration data were used to determine daily average temperatures and daily temperatures on the interview dates at each site. RESULTS The average age of the 1612 men was 66.57 ± 10.03 years. The mean International Prostate Symptom Score (IPSS) and symptom duration were 18.51 ± 6.77 and 3.79 ± 3.89 years, respectively. Daily average temperature and temperature difference ranged from -13.1 to 28.5 °C and 0 to 20.6 °C, respectively. Age was a significant risk factor for IPSS, symptom duration, prostate volume (PV), maximal urinary flow rate (Qmax), average urinary flow rate (Qave) and total voiding volume (P < 0.001) but not QOL. Logistic regression analysis after adjustment for age and PV revealed that Qave and total voiding volume were increased as the temperature declined. However, IPSS and Qmax did not show a statistically significant difference as the temperature declined. CONCLUSION Our findings did not demonstrate an increased clinically significant risk of LUTS severity in connection with ambient temperature in clinical practice.

Abstract
OBJECTIVE The aim of this study was to evaluate whether seasonal changes aggravate the symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), by serial administration of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) questionnaire for an extended period. MATERIAL AND METHODS Seventy-seven men with CP/CPPS were serially evaluated with the Korean version of the NIH-CPSI questionnaire every 2-3 months from October 2008 to October 2012. The mean duration of follow-up was 27.11 ± 10.00 months and the mean number of visits per patient was 14.68 ± 5.33 times during the study. RESULTS The number of patients complaining of breakthrough pain during the study was 31 in spring and autumn, nine in summer and 18 in winter. However, there were no significant differences in the mean NIH-CPSI scores across the seasons. In spring, summer and autumn, only urination symptoms correlated with quality of life (QoL) (r(2) = 0.277, p < 0.001). In winter, both pain items and urination symptoms correlated with QoL (pain: r(2) = 0.522, p < 0.001; urination symptoms: r(2) = 0.250, p < 0.001). CONCLUSION Although fewer severe pain attacks occurred in summer, the mean NIH-CPSI scores did not differ across seasons. The pain from CP/CPPS had a greater impact on QoL during winter than it did in the other seasons. In addition, pain was a more significant determinant of QoL than urination symptoms during winter.

Abstract
INTRODUCTION A better understanding of ejaculatory disorders has led to an increasing interest in nonpremature ejaculatory dysfunction (non-PE EjD). Current reviews on the subject use a symptom-based classification to describe ejaculatory dysfunction even when it is a single case report. While these reviews provide important information on the disorder, a clearer picture of the prevalence of non-PE EjD in relation to the community and various pathophysiologic states is needed. OBJECTIVES The objective of this study was to provide a systematic review of studies of non-PE EjD excluding single case reports. METHODS A systematic review of Medline for terms including ejaculation, orgasm or hematospermia. Association with terms delay, pain or headache was made. The search was restricted to male gender and articles written in English. Abstracts were reviewed and those mainly concerned with premature ejaculation were excluded. RESULTS A total of 333 articles on non-PE EjD were identified. The condition was reported in community-based studies. In certain patient populations, non-PE EjD was commonly reported in association with antidepressant and antipsychotic treatments, in patients with chronic prostatitis/chronic pelvic pain syndrome, patients with lower urinary tract symptoms particularly in association with medical or surgical treatment, patients with retroperitoneal surgery and in patients with neurological diseases. Few articles were concerned with treatment options. CONCLUSION There is a significant prevalence of non-PE EjD in the community and in association with particular disease states or as a side effect of medical or surgical interventions. There is a need to direct efforts to prevent and treat these conditions.

Abstract
AIM Chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS) is a common disabling condition that is primarily associated with pain in the urogenital region and disturbances in urinary and sexual function. Chronic pelvic pain symptoms are the most common presentation, especially perineal, lower abdominal, testicular, penile as well as ejaculatory pain. Other genitourinary tract complaints include voiding disorders and sexual dysfunction. We aimed in the study at examining the prevalence rates of premature ejaculation and erectile dysfunction in patients with chronic pelvic pain syndrome and comparing these rates with those of healthy control subjects. MATERIALS AND METHODS Between November 2006 and January 2008, 85 patients with the diagnosis of CP/CPPS were chosen for the study; 30 patients without regular sexual activity and 12 patients without inclusion criteria were excluded from the study. A total of 43 patients were included in the study. Twenty healthy volunteers without prostatitis-like syndromes were used as a control group. The sexual function of the patients and the healthy volunteers were evaluated using Arizona Sexual Function Questionary Form and International Index of Erectile Function (IIEF). Erectile dysfunction (ED), ejaculatio precox (EP) and pain on ejaculation (PEP) were investigated as sexual dysfunction. RESULTS The mean age of the patients was 33.7 (22-48) years; the mean symptom period was 37.7 (6-120) months, while the mean age of the control group was 32.4 (24-48) years. The mean NIH-CPSI score of the patient group was 26.1 (16-34). Patient group was classified as CPPS type IIIa and CPPS type IIIb. Mild and moderate erectile dysfunction (ED) was found in [9] 23.2% patients at the patient group and [2] 10% at the control group (P: 0.185). Severe erectile dysfunction was not found in both groups. Ejaculatio Precox (EP) was found at (29) 67.4% of the patient group and [7] 40% of the control group. Pain on ejaculation (PEP) was detected in [15] 37.2% of the patient group, while none of the control group had pain on ejaculation. More than one sexual dysfunction was found in [17] 41.8% of the patient group and none of the control group. Comparing patient group versus control group, ejaculation disorders (EP and PEP) and more than one sexual dysfunction disorder were statistically significant. According to ED, there is no statistical difference between the groups (P > 0.05). CONCLUSION Sexual function disorders, especially ejaculation disorders (EP and PEP), are frequently seen in CP/CPPS patients versus normal population. Age, symptoms period, symptom score and CP/CPPS subgroups are not risk factors for sexual function disorders. Patients with the diagnosis of CP/CPPS should be evaluated for sexual function disorders.

Abstract
OBJECTIVES Chronic pelvic pain syndrome is a common and serious health problem affecting the quality of life of men. We evaluated the prevalence of premature ejaculation (PE) in Chinese men with chronic pelvic pain syndrome and studied its correlation to chronic prostatitis. METHODS A total of 15,000 men (aged 15-60 years) were randomly recruited to take part in a survey to provide questionnaire-elicited information for sociodemographics, sexual function, National Institutes of Health-Chronic Prostatitis Symptom Index, and International Index of Erectile Function 5-item questionnaire. The eligible subjects of the present investigation were married with sexual activity. RESULTS Responses were collected from 12 743 men (84.95%). Of these men, 1071 (8.4%) reported having prostatitis-like symptoms. The incidence of chronic prostatitis was 4.5% (n = 571) for the entire group. Of the 7372 eligible men, the incidence of prostatitis-like symptoms, chronic prostatitis, and PE was 10.5% (n = 771), 5.0% (n = 370), and 15.3% (n = 1127), respectively. The group with PE had worse National Institutes of Health-Chronic Prostatitis Symptom Index scores (P < .05) and lower International Index of Erectile Function 5-item questionnaire scores (P < .05) than the patients without PE. Also, the percentage of prostatitis-like symptoms in the PE group was greater than that in the non-PE group (P < .05). The prevalence of PE was 64.1% and 36.9% in the prostatitis-like symptom and chronic prostatitis group, respectively, of the 7372 eligible men. CONCLUSIONS The results of our study showed a high prevalence of PE in patients with chronic prostatitis. An examination of the prostate, physically and microbiologically, should be considered during the assessment of patients with PE.

Abstract
OBJECTIVE To determine whether subjective or objective seasonal changes occur in patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH). MATERIAL AND METHODS A total of 31 patients with LUTS were observed for >5 years. Their International Prostate Symptom Score (IPSS), quality of life (QOL) score, maximum flow rate (Qmax), voided volume (VV) a nd post-void residual (PVR) we re measured every month. RESULTS Total IPSS, QOL, VV or PVR did not show any seasonal changes between the three seasons: summer (hot season: June to September); winter (cold season: December to March); and spring and fall (comfortable season: April, May, October and November). Furthermore, when the IPSS was examined by dividing it into storage symptoms (frequency, urgency and nocturia) and voiding symptoms (incomplete emptying, intermittency, weak stream and straining), no significant seasonal changes were detected. Only Qmax showed a significant seasonal change, being higher in both the cold season (median 10.4 ml/s) and the comfortable season (median 10.1 ml/s) than in the hot season (median 9.4 ml/s). CONCLUSIONS It has generally been thought that LUTS worsen in winter. Our results indicate that the IPSS and the QOL score remain nearly constant if they are determined regularly over an extended period of time. Qmax may however be influenced by seasonal changes in temperature.

Abstract
INTRODUCTION Prostatitis is a common, yet ill-defined condition without clear diagnostic criteria and treatment strategies. Previous studies examining the prevalence and correlates of prostatitis are limited in their inclusion of primarily white populations. The objective of the current study was to identify prevalence of and risk factors for prostatitis in a population-based sample of African-American men. METHODS In 1996, a probability sample of 703 African-American men, aged 40-79, residing in Genesee County, Michigan without a prior history of prostate cancer/surgery provided responses to a structured interview-administered questionnaire which elicited information regarding sociodemographics, current stress and health ratings, and past medical history, including history of physician diagnosed prostatitis, BPH and sexually transmitted diseases. Logistic regression was used to identify predictors of prostatitis after adjustment for age. RESULTS Forty-seven (6.7%) of the 703 men reported a history of prostatitis. Increased frequency of sexual activity and physical activity were significantly associated with decreased odds of disease. Moderate to severe lower urinary tract symptoms (LUTS) and a history of BPH were significantly associated with prostatitis after adjustment for age. CONCLUSION After adjustment for age, LUTS severity and history of BPH were associated with increased odds of prostatitis. BMI, physical activity and sexual frequency were associated with decreased odds of prostatitis. Finally, poor emotional and physical health, high perceived stress and low social support were associated with an increased risk of prostatitis history. Importantly, these findings suggest that the primary risk factors for this condition are largely modifiable and highlight potential targets for future prevention.

Prevalence of asymptomatic inflammatory (National Institutes of Health Category IV) prostatitis in young men according to semen analysis. Urology 2008; 71:1010-5. [PMID: 18455767 DOI: 10.1016/j.urology.2007.12.082] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2007] [Revised: 12/13/2007] [Accepted: 12/19/2007] [Indexed: 10/22/2022]
Abstract
OBJECTIVES To determine the prevalence of asymptomatic inflammatory (National Institutes of Health category IV) prostatitis in a cross-sectional community sample of young men. METHODS The study group consisted of 565 men aged 18.9 +/- 1.8 years (mean +/- standard deviation). Cytologic examination of all ejaculates (using Bryan-Leishman stained slides), as well as analysis for basic semen parameters (volume, concentration, and motility) and clinical examination for possible pathologies in the genital region, were performed. Subjects with any clinical symptoms of inflammation were excluded. Levels of prostate-specific antigen in blood serum and interleukin-6 in seminal plasma were determined as well. RESULTS The prevalence of asymptomatic inflammatory prostatitis (greater than 1 x 10(6) white blood cells [WBC]/mL in semen, according to World Health Organization guidelines) was 6.0%, but when we used a lower threshold suggested by our previous studies (greater than 0.2 x 10(6) WBC/mL), the prevalence was 19.0%. In this study the analysis did not show any significant effect of leukocytospermia on sperm quality, except higher sperm concentration in subjects with moderate leukocytospermia (0.2-1 x 10(6) WBC/mL). We did not detect any seasonal differences in the prevalence of asymptomatic inflammatory prostatitis. Interleukin-6 and prostate-specific antigen levels were significantly higher in leukocytospermic subjects than in those without leukocytospermia. CONCLUSIONS Asymptomatic inflammatory prostatitis has a notable prevalence among healthy young men, suggesting the need for further studies to investigate pathogenetic mechanisms of the disease. Lack of negative effect of leukocytospermia on basic semen parameters may indicate higher functional reserve of accessory sex glands in this age group.

Abstract
UNLABELLED OBJECTIVE OF THE SURVEY: To determine the usual practice of French urologists in relation to the diagnostic and therapeutic management of chronic prostatitis. MATERIAL AND METHODS A questionnaire on the diagnostic and therapeutic management of chronic prostatitis was sent by mail in June 2003 to 810 urologists, members of the Association Française d'Urologie and working in France. RESULTS 124 (15%) urologists returned the questionnaire. 61% of these urologists diagnosed less than 11 new cases of chronic prostatitis per year and 65% were not familiar with the new classification proposed in 1995 in the USA by the NIH (National Institutes of Heath) designed to remove this disease from the strict context of the prostate, placing greater emphasis on the concept of pain and introducing the concept of male chronic pelvic pain syndrome. 83% of urologists performed microbiological investigations often or always, but only 10% often or always performed a Meares and Stamey test comprising analysis of prostatic secretions after massage and 68% never performed this test. On the other hand, 76% of urologists ordered a first-stream urine culture, 61% ordered a second-stream urine culture and 76% ordered semen culture. 73% often or always prescribed antibiotics (82% used fluoroquinolones and 43% used the trimethoprim-sulfmethoxazole combination). Even in the absence of microbiological proof of infection, 41% of urologists often or always prescribed antibiotics, 89% sometimes or often prescribed an alpha-blocking agent, 89% sometimes, often or always prescribed a non-steroidal anti-inflammatory drug, 81% sometimes, often or always prescribed analgesics, 52% sometimes or often prescribed anxiolytics, and 66% sometimes or often referred the patient to another specialist. CONCLUSION This survey shows that chronic prostatitis, now generally referred to as "chronic pelvic pain syndrome", continues to raise diagnostic and therapeutic problems for French urologists.

Abstract
OBJECTIVE To investigate the features of chronic prostatitis (CP) during puberty and the effects of biofeedback on young males with this disease. PATIENTS AND METHODS In all, 40 patients were divided into two groups; group 1 included 25 pubertal patients with CP (mean age 16.5 years, sd 1.1) and group 2 was a control group including 15 patients (mean age 16.2 years, sd 1.2) with a normal lower urinary tract. National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) scores (three parts) were assessed individually in both groups. Expressed prostatic secretions and urine samples after prostate massage from group 1 were cultured to determine whether patients were infected with bacteria, and group 1 was categorized into various NIH types. Each patients in the two groups underwent urodynamics and group 1 were treated with biofeedback. RESULTS In group 1, there were one, three and 21 patients with type II, IIIA and IIIB prostatitis. The incidence of staccato voiding and detrusor-sphincter dyssynergia (DSD), and the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), maximum detrusor pressure (Pdetmax) and maximum urethral closure pressure (MUCP) between the groups were significantly different (P < 0.05). The total NIH-CPSI scores and all the subdomains between the groups before biofeedback were significantly different (P < 0.001). In group 1 the difference in NIH-CPSI scores and Qmax before and after biofeedback was significant (P < 0.05). CONCLUSIONS The main type of CP during puberty is IIIB; the dominating symptom is a voiding disorder. The impact on life and psychological effects are substantial. Pubertal boys with CP have pelvic floor dysfunction and several abnormal urodynamic values, i.e. staccato voiding, DSD, decreasing Qmax, and increasing Pdetmax and MUCP. The effect of biofeedback strategies for treating pubertal CP is satisfactory.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome is a multifactorial problem, which affects men of all ages and in all demographics. Recent studies have shown that the prevalence of prostatitis is approximately 2-10% among unselected men in North America, Europe and Asia. This data clearly indicates that chronic prostatitis constitutes an important problem in international health care. Nevertheless, the aetiology and pathogenesis of chronic prostatitis have yet to be clearly delineated, despite the numerous efforts which have been made, with regard to both basic and clinical research. In fact, factors other than leucocytes and bacteria have been shown to contribute to the symptoms typically associated with prostatitis. Studies of the epidemiology and determinants of prostatitis risk factors may also provide clues to the general aetiology of prostatitis. Other epidemiological data appears to indicate that certain as-yet-unknown factors might be associated with an increased tendency towards the development of chronic prostatitis. However, findings from most studies are considered to represent only preliminary data, because of the small sample sizes or lack of generalizability inherent to most of the studies. The identification and characterization of these relevant risk factors might accelerate or augment the development of preventive, diagnostic, and therapeutic strategies for the treatment of these syndromes.

Abstract
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 (CPSI). The CPSI provides scores for pain, urinary symptoms and QoL. In addition, a demographic profile, including age and partner (living with another) status, and a depressive symptom score were obtained. Regression modelling of QoL, adjusting for between-centre variability, examined the unique effects of age, partner status, urological symptoms, depressive symptoms and pain. RESULTS Urinary scores, depressive symptoms and pain intensity scores significantly predicted QoL for patients with CP/CPPS (higher CPSI QoL scores indicated more impairment; median 8.0, range 0-12). On average, for every 1-point increase in urinary scores, there was a corresponding increase in QoL score of 0.118 points (P = 0.001); for every 1-point increase in pain intensity score, there was a corresponding increase in QoL score of 0.722 points (P < 0.001); and for every 1-point decrease in depressive symptoms (lower scores equal poorer mood), the QoL score increased (poorer quality of life) by 0.381 points (P < 0.001). Age and partner status did not significantly contribute to poorer QoL. Urinary scores and depressive symptoms were significant predictors (P < 0.001) of pain in patients with CP/CPPS. CONCLUSIONS These data show that depressive symptoms and pain intensity significantly predict a poorer QoL in patients with CP/CPPS, and that these effects are independent of partner status, age and urinary status. In particular, pain intensity was the most robust predictor of a poorer QoL. Further data relating pain and psychological factors to CP/CPPS are highly recommended, to aid in determining specific factors for pain and its impact on QoL. These data are essential if empirically guided efforts to manage pain are to progress.

Abstract
OBJECTIVE To define lower urinary tract symptoms (LUTS) and their relationship to general practitioner (GP) visits and ethnicity among men in the New Zealand (NZ) population-based Wellington Region Community Prostate Study. SUBJECTS AND METHODS In 2001-2002 NZ European, Maori and Pacific Island participants were selected from the Wellington region of NZ. Demographic questions, the International Prostate Symptom Score and yearly GP attendance questions were completed by 862 subjects with no history of prostate cancer. RESULTS There were no significant differences in LUTS among the ethnic groups (P = 0.80) but symptom scores were positively correlated with age only for NZ Europeans (P < 0.001, r = 0.179). Overall, NZ populations have a lower prevalence of LUTS than is evident for ethnic groups in other countries. Pacific Islanders attended the GP more often than both NZ Europeans and Maori. CONCLUSION Ethnic differences in age-related urinary symptoms and visits to the GP are important for informing culturally appropriate clinical practice and prostate health promotion with minority groups.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is the most common of the prostatitis syndromes. It is characterised by pelvic pain, with or without voiding symptoms. CP/CPPS accounts for 2 million office visits in the US alone. Recent epidemiological studies have shown that CP/CPPS can affect men at any age, including those in their 80s. The aetiology is unknown but proposals include infectious, autoimmune, neurologic and psychiatric causes. Men with CP/CPPS are much more likely to have had a past medical history of cardiovascular, neurologic, psychiatric or infectious disease (particularly sinusitis) as compared with asymptomatic individuals. Although leucocytes are commonly found in the prostatic fluid of these men, they do not correlate with the symptoms. The clinical evaluation now includes a validated, self administered symptom score, the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), which was designed as an outcome measure for treatment trials. This can aid in diagnosis and follow-up of patients' response to therapy. Treatment for CP/CPPS is empiric and limited by a lack of randomised, placebo-controlled clinical trials. Antimicrobials are commonly used to treat the symptoms of CP/CPPS. However, the finding that asymptomatic men have equal or greater numbers of bacteria which localise to the prostatic fluid, compared with men with CP/CPPS, has raised doubts about the contribution of infection to the symptoms. Other commonly used drugs include alpha-adrenoceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents. The adverse effects of these medications are a concern in older men with CP/CPPS. Other therapies available include minimally invasive procedures such as microwave thermotherapy and transurethral needle ablation, and now neuromodulation devices.Although much progress has been made, particularly in the last 7 years, considerable work still remains to be done to determine the aetiology and pathogenesis of CP/CPPS, and to develop mechanism based therapy that is shown to be effective in controlled trials.

Abstract
PURPOSE We evaluate the agreement between self-reported physician diagnosed prostatitis and pain questions from the National Institutes of Health Chronic Prostatitis Symptom Index (CPSI). MATERIALS AND METHODS A randomly selected cohort of white men 47 to 90 years old from Olmsted County, Minnesota completed a study questionnaire on a history of physician diagnosed prostatitis in the preceding 2 years, including the CPSI questions. The medical records were also reviewed for physician diagnosis of chronic prostatitis during the preceding 10 years. RESULTS Of 1,543 men 27 (1.7%) reported a physician diagnosis of prostatitis in the preceding 2 years. There were strong associations between self-reported prostatitis and pain at the tip of the penis (OR 6.3, 95% CI 1.4, 28.5), ejaculatory (5.9, CI 1.3, 26.6) and testicular (3.6, 1.2, 10.8) pain. The chance corrected agreement between self-reported prostatitis and pain symptoms was low at 0.01 (pubic pain) to 0.07 (pain at the tip of the penis, ejaculatory pain and testicular pain). Agreement in positive responses was also low at 3.7% (perineal pain) to 8% (pain at the tip of the penis, ejaculatory pain and testicular pain). The predictive value of the modified total CPSI score for prostatitis was 0.67, which was better than chance (0.5). Associations based on medical record ascertainment of prostatitis during followup were weak, and the area under the curve was 0.57, which was no better than chance. CONCLUSIONS These findings demonstrate low agreement between CPSI-like pain measures and self-reported physician diagnosed prostatitis. The stronger associations between pain symptoms and self-reported diagnosed prostatitis, and the moderate predictive ability of the modified total CPSI score measures for self-reported prostatitis compared to medical record ascertainment demonstrate the sensitivity of the CPSI to prevalent symptoms. Thus, the tool may be best used to evaluate the severity of current symptoms rather than to assess the presence or absence of prostatitis.

Abstract
PURPOSE OF REVIEW This review covers recent developments in the classification, epidemiology, aetiology, diagnosis and treatment of patients diagnosed with chronic prostatitis (NIH classification types II, IIIa/IIIb and IV prostatitis) in the period of review (2001-2002). RECENT FINDINGS Recent studies highlight some of the problems with the 1995 NIH classification. Epidemiological studies have confirmed that "prostatitis" is common, with a prevalence of 10-15%. Associations of prostatitis include benign prostatic hyperplasia, sexually transmitted disease, lower urinary tract symptoms, stress, and reduced sunlight exposure. Elevated levels of cytokines in the seminal plasma and prostatic secretions have been detected in men with chronic prostatitis compared with normal individuals, suggesting an active inflammatory process in the male genital tract. This inflammatory reaction may be mediated by an adaptive immune response directed against a genital tract antigen(s) (autoimmunity). Increased levels of bacterial 16S ribosomal DNA in the prostates of men with chronic prostatitis compared with controls are compatible with the notion that a bacterial inflammatory event initiates an auto-immune process; however, the role of bacteria in the continuation of symptoms is unknown. SUMMARY The aetiology of chronic pelvic pain syndrome is still not certain, although an auto-immune process is favoured. Further research is required to determine the putative auto-antigen, the immune responses of patients, the role of bacteria in the inflammatory process, and the patients' pain response to genitourinary insults. As yet no diagnostic tests (other than to eliminate other pathology) and few treatments for chronic prostatitis can be recommended on the basis of scientific evidence.

Abstract
OBJECTIVES To examine the impact of urinary symptoms on bothersomeness and quality of life among young men in a community. METHODS The National Institutes of Health-Chronic Prostatitis Symptom Index was used to identify men with urinary symptoms. The questionnaire also queried about sociodemographic characteristics. A total of 15,264 men without pain or discomfort suggestive of prostatitis were included in this study. RESULTS Of the 15,264 subjects, 43.6% reported that they experienced urinary symptoms. With regard to symptom severity, 3.4% did not believe their bladder emptied fully after urinating more than one time in five, and 9.7% had to urinate again within 2 hours more than one time in five. Men in major towns had more severe symptoms, including incomplete emptying and frequency, than those in other areas. Men with a high educational level were less likely to report that they experienced severe frequency. Multivariate logistic regression analyses indicated that urinary symptoms significantly affected bothersomeness and quality of life of young men. CONCLUSIONS In a community-based population of healthy 20-year-old Korean men, the prevalence of urinary symptoms was 43.6%. The results of the study indicated that demographic variables might influence the prevalence of urinary symptoms in young men. In addition, our findings suggest that young men with urinary symptoms experience a negative impact on their quality of life.

Abstract
Prostatitis reflects a broad spectrum of prostatic infections, both acute and chronic. Chronic prostatitis, known as National Institutes of Health category III or chronic pelvic pain syndrome, broadly defines a disease that is still poorly understood, and as a consequence, difficult to treat. Typical symptoms include pelvic pain and voiding dysfunction. Infection is often cited as the cause of this condition, despite frequent negative cultures. A close look at the local prostatic microenvironment may yield clues. The role of inflammatory mediators and what stimulates them can point to potential sites of prevention. A genetic link or relationship to other diseases may prove to be part of the cause. Furthermore, a neurologic source, whether anatomic or psychologic, has been strongly debated. Ultimately, it may become clear that chronic prostatitis represents the final common result of a disease that originates from a cascade of multiple stimuli.
