PURPOSE: The purpose of this study was to determine whether histologic inflammation (HI) in initial and repeat prostate biopsy specimens was significantly associated with the detection of prostate cancer. MATERIALS AND METHODS: Between 2005 and 2017, the clinicopathological records of patients with high prostate-specific antigen (PSA) levels who underwent initial and repeat prostate biopsies were retrospectively reviewed. The presence of HI and its degree in each biopsied specimen were interpreted by one uropathologist with 20 years of experience. The association between HI and cancer diagnosis was statistically assessed, with p < 0.05 considered significant, and the cancer and non-cancer groups were compared. RESULTS: Among the 522 patients with a median PSA levels of 6.5 ng/dL, including 258 (49.4%) whose cancer was diagnosed following repeat biopsy, the median degrees of HI in the initial and repeat biopsies were 25.0% and 41.7%, respectively. Furthermore, 211 (40.4%) and 247 (47.3%) patients had HI (> 0%) on biopsied specimens, respectively. Comparison of the cancer and noncancer groups revealed that a greater rate of HI specimens in the initial biopsy was associated with fewer prostate cancer diagnoses following repeat biopsy (p < 0.001). Other comparisons between the cancer and non-cancer groups showed that the cancer group had a significantly higher rate of hypertension, whereas those non-cancer group had a significantly higher rate of benign prostatic hyperplasia and prostatitis (p < 0.05). CONCLUSION: A finding of a lesser degree of HI in the initial and a greater degree of HI in the repeat biopsied specimens was associated with the higher probability of cancer diagnosis in patients with high PSA levels.

Prostate cancer (CaP) is the most common cancer diagnosed among men in the United States and the fifth most common cancer among men in Korea. Unfortunately, the early stages of CaP may have no symptoms. Thus, early detection is very important and physicians managing voiding dysfunction must have awareness about CaP. The traditional tests used for early detection of CaP are the prostate-specific antigen (PSA) blood test and digital rectal examination. However, a high PSA level is not specific for CaP. Benign prostatic hyperplasia, prostatitis, urinary tract infection, and urinary retention can all cause a high PSA level. Thus, no test shows sufficient accuracy to truly be useful for screening men for CaP. A prostate biopsy is the only method that yields a definitive diagnosis of CaP; however, this test is invasive and uncomfortable. Recently, new biomarkers for CaP detection have been proposed to improve the accuracy of the PSA test. In this review, we summarize our knowledge of various new biomarkers, including PSA-associated biomarkers (the prostate health index and 4Kscore), molecular biomarkers (PCA3, TMPRSS2: ERG fusion gene, and various miRNAs), and proteomics-associated biomarkers, and the ways in which they may improve the detection rate of CaP. Accordingly, this review can raise awareness about CaP to physicians managing voiding dysfunction and be a good reference for them.

Urinary tract infections (UTIs) are infectious diseases that commonly occur in communities. Although several international guidelines for the management of UTIs have been available, clinical characteristics, etiology and antimicrobial susceptibility patterns may differ from country to country. This work represents an update of the 2011 Korean guideline for UTIs. The current guideline was developed by the update and adaptation method. This clinical practice guideline provides recommendations for the diagnosis and management of UTIs, including asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, complicated pyelonephritis related to urinary tract obstruction, and acute bacterial prostatitis. This guideline targets community-acquired UTIs occurring among adult patients. Healthcare-associated UTIs, catheter-associated UTIs, and infections in immunocompromised patients were not included in this guideline.

Prostatic calculi often occur in middle-aged and old men. Prostatic calculi are usually classified as primary/endogenous stones or secondary/extrinsic stones. Endogenous stones are commonly caused by obstruction of the prostatic ducts around the enlarged prostate by benign prostatic hyperplasia (BPH) or by chronic inflammation. Extrinsic stones occur mainly around the urethra, because they are caused by urine reflux. The exact prevalence of prostatic calculi is not known, and it has been reported to vary widely, from 7% to 70%. Most cases of prostatic calculi are not accompanied by symptoms. Therefore, most cases are found incidentally during the diagnosis of BPH using transrectal ultrasonography (TRUS). However, prostatic calculi associated with chronic prostatitis may be accompanied by chronic pelvic pain. Rare cases have been reported in which extrinsic prostatic calculi caused by urine reflux have led to voiding difficulty due to their size. More than 80% of prostatic calculi are composed of calcium phosphate. Prostatic calculi can be easily diagnosed using TRUS or computed tomography. Treatment is often unnecessary, but if an individual experiences difficulty in urination or chronic pain, prostatic calculi can be easily removed using a transurethral electroresection loop or holmium laser.

We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent. Prostatitis was the highest diagnosis made in the outpatient service, while varicocele was ranked the highest in the inpatient service. The incidence rates of urologic disease varied from 12.3 to 34.2 cases per 1,000 person-years. The urologic disease in conscripted men showed different distribution when we separated the population into conscripted and professional soldiers. Epididymoorchitis was the highest disease followed by urolithiasis, dysuresia, and balanoposthitis in 2013. This study underscores that the urologic disease has spent significant amount of health care resources in the Korean military. This calls for further study to find any significant difference and contributing factors of the urologic disease in the military and the civilian population.

Objective: To investigate the correlation between the syndrome types of traditional Chinese medicine (TCM) and clinical symptoms of benign prostatic hyperplasia (BPH) with chronic prostatitis (BPH-CP). METHODS: We selected 150 cases of BPH-CP in this study and divided them into 7 TCM syndrome types. Using univariate and multivariate logistic regression analyses, we studied the correlation of each TCM syndrome type with the age, disease course, prostate volume, postvoid residual urine volume (PVR), prostate-specific antigen (PSA) level, maximum urinary flow rate (Qmax), and International Prostate Symptoms Score (IPSS). RESULTS: Kidney-yin deficiency was correlated positively with the prostate volume but negatively with Qmax and IPSS; kidney-yang deficiency positively with the age and prostate volume but negatively with IPSS; the damp heat syndrome positively with the PSA level but negatively with the disease course, prostate volume and Qmax; the spleen-qi deficiency syndrome positively with the prostate volume but negatively with the disease course; liver-qi stagnation positively with the disease course but negatively with the age, prostate volume and PVR; the syndrome of qi stagnation and blood stasis positively with the disease course and IPSS but negatively with PVR; the syndrome of lung-heat and qi blockage positively with the age, Qmax and IPSS but negatively with the disease course. CONCLUSIONS The TCM syndrome types of BPH-CP are closely correlated to their clinical symptoms. The analysis of the clinical objective indexes of BPH-CP can provide some reliable evidence for accurate identification of the TCM syndrome type of the disease.

Objective: To investigate the value of the content of neutrophil elastase (NE) in the expressed prostatic secretion (EPS) and seminal plasma (SP) as a combined predictor in the diagnosis of type IIIA prostatitis with secondary infertility. METHODS: This study included 62 fathers (group A) and 67 infertile men (group B), all with type IIIA prostatitis, and another 57 controls with no genitourinary tract disease (group C). We measured the NE contents in the EPS and SP, obtained the results of routine semen and EPS examinations and Chronic Prostatitis Symptom Index (CPSI), and calculated the ratio of EPS NE/SP NE by binary logistic regression analysis. RESULTS: The combined predictor of type IIIA prostatitis with secondary infertility was SP NE-2 × EPS NE. Among the 129 patients with type IIIA prostatitis, the combined predictor was correlated strongly negatively with the WBC count in the EPS (r = －0.914, P <0.01), negatively with CPSI, sperm concentration, sperm mobility and sperm viability (P <0.01), but not significantly with the WBC count or pH value in the SP (P >0.05). The mean values of the combined predictor in groups A, B, and C were －2 238 (95% CI: －2 595 to －2 054), －1 511 (95% CI: －1 778 to －1 307), and －148 (95% CI: －181 to －118), respectively, with statistically significant differences between the cases and controls as well as between groups A and B (P <0.01). The area under the ROC curve of the combined predictor for the diagnosis of type IIIA prostatitis with secondary infertility was 0.71 (P <0.001). CONCLUSIONS The content of neutrophil elastase in the EPS combined with that in the seminal plasma contributes to the diagnosis of type IIIA prostatitis with secondary infertility, which is superior to either the neutrophil elastase content in the EPS or that in the seminal plasma used alone.

OBJECTIVETo investigate the correlation of the levels of interleukin-8 (IL-8) and IL-6 in the prostatic fluid with serum levels of serum prostate-specific antigen (PSA) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.

METHODSA series of 211 patients undergoing surgery of BPH were divided into BPH group (n=75) and BPH with prostatitis group (n=136) according to the white blood cell count in the prostatic fluid. The clinical and laboratory findings were compared between the two groups, and stepwise regression analysis was used to assess the association of IL-8 and IL-6 with serum PSA level.

RESULTSNo significant differences were found in age, BMI, blood pressure, blood glucose, blood lipids, IPSS score, PSA-Ratio, or prostate volume between the two groups (P<0.05). The patients with prostatitis had significantly increased serum PSA and prostate fluid IL-8 and IL-6 levels compared with those without prostatitis (P<0.001). Multiple linear regression analysis showed that IL-8 and IL-6 levels and white blood cell count in the prostatic fluid were all positively correlated with serum PSA level.

CONCLUSIONProstatitis is an important risk factor for elevated serum PSA level in patients with BPH, and both IL-8 and IL-6 levels in the prostatic fluid are correlated with serum PSA level.
