Abstract
PURPOSE Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses. MATERIALS AND METHODS Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted. RESULTS UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients. CONCLUSION Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.

Abstract
Importance The antiandrogenic effect of the 5α-reductase inhibitor (5-ARI) has been investigated for its role in preventing male-predominant cancers. Although 5-ARI has been widely associated with prostate cancer, its association with urothelial bladder cancer (BC), another cancer experienced predominantly by males, has been less explored. Objective To assess the association between 5-ARI prescription prior to BC diagnosis and reduced risk of BC progression. Design, Setting, and Participants This cohort study analyzed patient claims data from the Korean National Health Insurance Service database. The nationwide cohort included all male patients with BC diagnosis in this database from January 1, 2008, to December 31, 2019. Propensity score matching was conducted to balance the covariates between 2 treatment groups: α-blocker only group and 5-ARI plus α-blocker group. Data were analyzed from April 2021 to March 2023. Exposure Newly dispensed prescriptions of 5-ARIs at least 12 months prior to cohort entry (BC diagnosis), with a minimum of 2 prescriptions filled. Main Outcomes and Measures The primary outcomes were the risks of bladder instillation and radical cystectomy, and the secondary outcome was all-cause mortality. To compare the risk of outcomes, the hazard ratio (HR) was estimated using a Cox proportional hazards regression model and difference in restricted mean survival time analysis. Results The study cohort initially included 22 845 males with BC. After propensity score matching, 5300 patients each were assigned to the α-blocker only group (mean [SD] age, 68.3 [8.8] years) and 5-ARI plus α-blocker group (mean [SD] age, 67.8 [8.6] years). Compared with the α-blocker only group, the 5-ARI plus α-blocker group had a lower risk of mortality (adjusted HR [AHR], 0.83; 95% CI, 0.75-0.91), bladder instillation (crude HR, 0.84; 95% CI, 0.77-0.92), and radical cystectomy (AHR, 0.74; 95% CI, 0.62-0.88). The differences in restricted mean survival time were 92.6 (95% CI, 25.7-159.4) days for all-cause mortality, 88.1 (95% CI, 25.2-150.9) days for bladder instillation, and 68.0 (95% CI, 31.6-104.3) days for radical cystectomy. The incidence rates per 1000 person-years were 85.59 (95% CI, 80.53-90.88) for bladder instillation and 19.57 (95% CI, 17.41-21.91) for radical cystectomy in the α-blocker only group and 66.43 (95% CI, 62.22-70.84) for bladder instillation and 13.56 (95% CI, 11.86-15.45) for radical cystectomy in the 5-ARI plus α-blocker group. Conclusions and relevance Results of this study suggest an association between prediagnostic prescription of 5-ARI and reduced risk of BC progression.

Abstract
RATIONALE & OBJECTIVE Microscopic hematuria is an uncertain risk factor for chronic kidney disease (CKD). We investigated the association between persistent or single episodes of microscopic hematuria and the development of incident CKD, overall and separately among men and women. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS A total of 232,220 Korean adults without CKD at baseline who underwent repeated regular health examinations at Kangbuk Samsung Health Study formed the study cohort. EXPOSURE Microscopic hematuria was defined by≥5 red blood cells per high-power field. Participants were categorized into 1 of 4 groups according to the presence of hematuria at 2 consecutive examinations: (1) no hematuria at both examinations (reference group); (2) hematuria followed by no hematuria (regressed hematuria group); (3) no hematuria followed by hematuria (developed hematuria group); and (4) hematuria at both examinations (persistent hematuria group). OUTCOME CKD was defined as an estimated glomerular filtration rate<60mL/min/1.73m2 or proteinuria (1+or more on dipstick examination). ANALYTICAL APPROACH Semiparametric proportional hazards models were used to estimate hazard ratios. RESULTS During a 4.8-year median follow-up period, 2,392 participants developed CKD. Multivariable-adjusted hazard ratios for incident CKD, comparing the regressed, developed, and persistent hematuria groups to the no-hematuria group were 1.85 (95% CI, 1.35-2.53), 3.18 (95% CI, 2.54-3.98), and 5.23 (95% CI, 4.15-6.59), respectively. The association between persistent hematuria and incident CKD was stronger in men than women (P for interaction<0.001), although a statistically significant association was observed in both sexes. LIMITATIONS Lack of albuminuria and inability to consider specific glomerular diseases. CONCLUSIONS Men and women with microscopic hematuria, especially persistent hematuria, may be at increased risk of CKD.

Abstract
The role of the gut microbiome in the development of renal stone diseases has not been well characterized. This study focused on the taxonomic and functional profiles of gut microbiomes according to the prevalence and incidence of nephrolithiasis. Stool samples from 915 Korean adults were collected at baseline. Participants were followed for a median of 4.0 years. We evaluated the biodiversity of the gut microbiota and taxonomic profiles associated with nephrolithiasis status, using 16S rRNA gene sequencing. Nephrolithiasis status was categorized into three groups: control (no-stone at both baseline and follow-up visits), incidental nephrolithiasis, and prevalent nephrolithiasis. Compared to the control and incidental nephrolithiasis, the prevalent nephrolithiasis showed a reduced evenness in alpha diversity. Nephrolithiasis was associated with a reduced abundance of some key taxa involved in short-chain fatty acid production. Moreover, the abundance of Bifidobacterium, which possess oxalate-degrading ability, was higher in the control. Conversely, there was no significant difference in the bacterial composition between the incidental and prevalent nephrolithiasis. In our study with repeated nephrolithiasis measurements, prevalent renal stones were associated with an altered gut microbiota composition compared to the control. Besides the known oxalate degradation pathway, other functional pathways inferred in this study require further investigation.

Abstract
BACKGROUND Intractable bladder hemorrhage from pelvic malignancy can be potentially life-threatening and its management can be a challenging clinical problem. PURPOSE To evaluate safety, efficacy, and clinical outcome of superselective vesical artery embolization for the control of intractable bladder hemorrhage from pelvic malignancy. MATERIAL AND METHODS Between January 2010 and September 2018, 20 patients underwent superselective vesical artery embolization for intractable hematuria secondary to pelvic malignancy arising from or invading the bladder. Treatment details and clinical outcomes were obtained. RESULTS There were 12 men and 8 women (mean age = 77 years). Bilateral embolization was performed in 10 patients and unilateral approach in 10 patients. Two patients died within four days after embolization due to underlying heart failure and systemic metastasis, respectively. The remaining 18 patients had a follow-up of >30 days. Bleeding was controlled after the first embolization in 17/18 patients and after a repeat embolization in the remaining one patient. The mean follow-up period of 18 patients was 10.6 months (range = 1-77 months). Late recurrent hemorrhage (≥ 30 days after embolization) was reported in 6 (33.3%) patients. Five of these six patients underwent repeat embolization. There were no major complications related to embolization. CONCLUSION Palliative superselective vesical artery embolization is a feasible, effective, and safe procedure to control intractable hematuria in patients with pelvic malignancy.

Abstract
Aim This study evaluated the prognosis and survival predictors for bladder urachal carcinoma (UC), based on large scale multicenter cohort with long term follow-up database. Methods A total 203 patients with bladder UC treated at 19 hospitals were enrolled. Clinical parameters on carcinoma presentation, diagnosis, and therapeutic methods were reviewed for the primary cancer and for all subsequent recurrences. The stage of UC was stratified by Mayo and Sheldon pathological staging system. Oncological outcomes and the possible clinicopathological parameters associated with survival outcomes were investigated. Results The mean age of the patients was 54.2 years. Among the total of 203 patients, stages I, II, III, and IV (Mayo stage) were 48 (23.8%), 108 (53.5%), 23 (11.4%), and 23 (11.4%), respectively. Gross hematuria and bladder irritation symptoms were the two most common initial symptoms. The mean follow-up period was 65 months, and 5-year overall survival rates (OS), cancer-specific survival rates (CSS), and recurrence-free survival rates (RFS) were 88.3, 83.1, and 63.9%, respectively. For the patients with Mayo stage ≥III, OS, CSS, and RFS were significantly decreased to 38.0, 35.2, and 28.4%, respectively. The higher pathological stage (Mayo stage ≥III, Sheldon stage ≥IIIc), positive surgical margin (PSM), and positive lymphovascular invasion (PLM) were independent predictors of shorter OS, CSS, and RFS. Conclusion The pathological stage, PSM, and PLM were significantly associated with the survival of UC patients, emphasizing an importance of the complete surgical resection of tumor lesion.

Purpose To analyze the efficacy and safety of standard-dose antimuscarinic treatment on male patients with overactive bladder (OAB) symptoms showing poor efficacy after low-dose antimuscarinics. Materials and Methods We retrospectively reviewed the data of 566 male patients aged ≥40 with OAB symptoms between January 2017 and June 2018. They were treated with low-dose antimuscarinics for at least 4 weeks and showed poor efficacy; therefore, they were switched to standard dose antimuscarinic treatment (5 mg of solifenacin) for ≥12 weeks. The international prostate symptom score (IPSS) and overactive bladder symptom score (OABSS) at baseline (V0), 4 weeks (V1), and 12 weeks (V2) were analyzed. Post void residual urine volume (PVR) was also recorded. Results The median age, body mass index, and prostate-specific antigen levels were 69.0 years, 24.2 kg/m2, and 1.24 ng/dL, respectively. The mean value of the total IPSS and OABSS significantly decreased between V0 and V2 (from 16.73 to 13.69 and 7.33 to 5.34, respectively, all p<0.001). All component scores from each questionnaire demonstrated a significant decrease except for numbers three and six on the IPSS questionnaire. PVR was increased from V0 to V2 (36.40 to 68.90 mL, p=0.015). Four and nine patients experienced constipation and thirst, respectively, and all adverse effects were graded as ≤2. Conclusions Standard dose antimuscarinic treatment using solifenacin (5 mg) may be a safe and effective treatment for patients with OAB symptoms refractory to low-dose antimuscarinic treatment.

Abstract
RATIONALE & OBJECTIVE The effect of glycemic status on nephrolithiasis risk remains controversial. This study sought to examine the association of glycemic status and insulin resistance with incident nephrolithiasis. STUDY DESIGN A retrospective cohort study. SETTING & PARTICIPANTS 278,628 Korean adults without nephrolithiasis who underwent a comprehensive health examination between 2011 and 2017. EXPOSURES Glucose level, glycated hemoglobin level, and Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). OUTCOME Nephrolithiasis ascertained using abdominal ultrasound. ANALYTICAL APPROACH A parametric proportional hazard model was used to estimate adjusted HRs and 95% CIs. We explored prespecified potential sex differences in the association of glycemic status and incident nephrolithiasis. RESULTS During a median follow-up of 4.2 years, 6,904 participants developed nephrolithiasis. Associations between levels of glycemic status and incident nephrolithiasis were examined separately in men and women (P for interaction = 0.003). Among men, multivariable-adjusted HRs for incident nephrolithiasis comparing glucose levels of 90-99, 100-125, and ≥ 126 mg/dL were 1.10 (95% CI, 1.01-1.19), 1.11 (95% CI, 1.02-1.21), and 1.27 (95% CI, 1.10-1.46), respectively, while HRs for incident nephrolithiasis comparing glycated hemoglobin levels of 5.7%-5.9%, 6.0%-6.4%, and 6.5%-<5.7% were 1.03 (95% CI, 0.96-1.10), 1.18 (95% CI, 1.07-1.31), and 1.20 (95% CI, 1.06-1.37), respectively. The HR for incident nephrolithiasis comparing the highest HOMA-IR quintile to the lowest quintile was 1.18 (95% CI, 1.06-1.31). Among women, no apparent association was found between glycemic status and nephrolithiasis risk. LIMITATIONS Glucose tolerance testing and computed tomography assessment for nephrolithiasis were not available. CONCLUSIONS Higher glycemic values, even within the normoglycemic range, and HOMA-IR were positively associated with increased risk for nephrolithiasis, associations that were only observed among men. Insulin resistance and hyperglycemia may contribute to the development of nephrolithiasis, particularly among men.

Abstract
We aimed to evaluate the current nationwide trend, efficacy, safety, and quality of life (QoL) profiles of hormone treatment in real-world practice settings for prostate cancer (PCa) patients in Korea. A total of 292 men with any biopsy-proven PCa (TanyNanyMany) from 12 institutions in Korea were included in this multi-institutional, observational study of prospectively collected data. All luteinizing hormone-releasing hormone (LHRH) agonists were allowed to be investigational drugs. Efficacy was defined as (1) the rate of castration (serum testosterone ≤50 ng dl−1) at 4-week visit and (2) breakthrough (serum testosterone >50 ng dl−1 after castration). Safety assessments included routine examinations for potential adverse events, laboratory tests, blood pressure, body weight, and bone mineral density (BMD, at baseline and at the last follow-up visit). QoL was assessed using the Expanded Prostate Cancer Index Composite-26 (EPIC-26). The most common initial therapeutic regimen was LHRH agonist with anti-androgen (78.0%), and the most commonly used LHRH agonist for combination and monotherapy was leuprolide (64.0% for combination and 58.0% for monotherapy). The castration and breakthrough rates were 78.4% and 6.6%, respectively. The laboratory results related to dyslipidemia worsened after 4 weeks of hormone treatment. In addition, the mean BMD T-score was significantly lower at the last follow-up (mean: −1.950) compared to baseline (mean: −0.195). The mean total EPIC-26 score decreased from 84.8 (standard deviation [s.d.]: 12.2) to 78.3 (s.d.: 8.1), with significant deterioration only in the urinary domain (mean: 23.5 at baseline and 21.9 at the 4-week visit). These findings demonstrate the nationwide trend of current practice settings in hormone treatment for PCa in Korea.

Abstract
RATIONALE Although PSA (prostate-specific antigen)-a tumor marker for prostate cancer-has been reported to be associated with cardiovascular disease (CVD) risk factors, studies on the association of PSA with subclinical and clinical CVD remain limited. OBJECTIVE We examined the association of total serum PSA within the reference range with coronary artery calcium (CAC) score and CVD mortality. METHODS AND RESULTS A cross-sectional study was performed in 88 203 Korean men who underwent a health checkup exam including cardiac tomography estimation of CAC score. Logistic regression model was used to calculate odds ratios with 95% CIs for prevalent CAC. PSA levels were inversely associated with the presence of CAC. After adjusting for potential confounders, multivariable-adjusted odds ratio (95% CIs) for prevalent CAC comparing PSA quartiles 2, 3, and 4 to the first quartile were 0.96 (0.90-1.01), 0.88 (0.83-0.93), and 0.85 (0.80-0.90), respectively ( P for trend, <0.001). A cohort study was performed in 243 435 Korean men with a mean age of 39.3 years, PSA values of <4.0 ng/mL, and without known CVD or prostate disease who were followed up with for ≤14 years for CVD mortality (median, 7.3 years). CVD deaths were ascertained through linkage to national death records. Hazard ratios and 95% CIs for CVD mortality were estimated using Cox proportional hazards regression analyses. During 1 829 070.1 person-years of follow-up, 336 CVD deaths were identified. After adjustment for potential confounders, multivariable-adjusted hazard ratios (95% CIs) for CVD mortality comparing PSA quartiles 2, 3, and 4 to the lowest quartile were 0.90 (0.66-1.22), 0.79 (0.58-1.08), and 0.69 (0.51-0.93), respectively. CONCLUSIONS Serum total PSA levels within the reference range showed an inverse association with subclinical atherosclerosis and CVD mortality in young and middle-aged Korean men, indicating a possible role of PSA as a predictive marker for subclinical and clinical CVD.

Abstract
The renal outcome of solitary kidney remains controversial. We examined the longitudinal association of congenital or acquired solitary kidney with the development of chronic kidney disease (CKD). A cohort study was performed involving 271,171 Korean men and women free of CKD at baseline who underwent a health screening program and who were followed annually or biennially for an average of 5.4 years. Solitary kidney was determined based on ultrasonographic findings. CKD was defined as an estimated glomerular filtration rate of < 60 ml/min/1.73 m2 and/or the presence of proteinuria in two or more consecutive visits. During 1,472,519.6 person-years of follow-up, 2989 participants developed CKD (incidence rate: 2.0 per 1000 person-years). After adjustment for potential confounders, the aHR (95% CIs) for incident CKD comparing solitary kidney to the control was 3.26 (1.63-6.54). In analyses of cause-specific solitary kidney, aHR (95% CIs) for CKD comparing unilateral nephrectomy and congenital solitary kidney to the control were 6.18 (2.31-16.49) and 2.22 (0.83-5.92), respectively. The association between solitary kidney and CKD was stronger in men. Having a solitary kidney was independently associated with an increased risk of CKD development. Therefore, preventive strategies for reducing the risk of CKD are required in individuals with a solitary kidney.

Abstract
OBJECTIVES To provide surgical treatment trends for urinary stone disease in Korea. METHODS We analyzed medical service claim data of surgical treatments to urinary stone disease submitted by medical service providers from the Health Insurance Review and Assessment Service from 2009 to 2016. RESULTS There was a significantly increasing trend among outpatients and inpatients for urinary stone disease from 2009 to 2016 (R2 = 0.643, P = 0.017; R2 = 0.575, P = 0.029). The number of shock wave lithotripsy for treating urinary stone disease increased by 16% from 89 553 in 2009 to 104 013 in 2016 (R2 = 0.684). The number of ureteroscopic lithotripsy increased by 97% from 6106 in 2009 to 12 057 in 2016 (R2 = 0.99). The number of flexible ureteroscopic lithotripsy increased by 16-fold from 219 in 2009 to 3712 in 2016 (R2 = 0.756). The number of percutaneous nephrolithotomy increased by 99.7% from 919 in 2009 to 1835 in 2016 (R2 = 0.987). The use of non-contrast and contrast-enhanced computed tomography in the diagnostic codes for urinary stone disease increased by 394.8% and 263.3% from 2009 to 2016, respectively (R2 = 0.83; R2 = 0.967). Conversely, the use of intravenous pyelography decreased 26.2% over the same period (R2 = 0.945). CONCLUSIONS Outpatient and inpatient procedures for urinary stone disease have increased over the past 8 years in Korea. Shock wave lithotripsy is the most widely used treatment modality for urinary stone disease, and endoscopic surgical procedures are rapidly being implemented. There has been a steep increase in the use of computed tomography, whereas conventional intravenous pyelography is declining.

Abstract
AIMS To evaluate the efficacy and safety of mirabegron in males with overactive bladder (OAB) symptoms. METHODS In total, 464 males with OAB symptoms were enrolled from 14 institutes and were sorted into either the mirabegron 50 mg (n = 310) or placebo (n = 154) groups. The change in (i) the mean number of 24-h micturition episodes; (ii) OAB Symptom Scale (OABSS); and (iii) International Prostate Symptom Score (IPSS) from baseline to 12 weeks of treatment were compared between the two groups. Safety assessments included treatment-emergent adverse events, blood pressure, pulse rate, postvoid residual volume, and maximum urinary flow rate. After 12 weeks, the study was extended for 14 additional weeks by administering mirabegron 50 mg to both groups. RESULTS The reduction in the mean number of 24-h micturition episodes from baseline to 12 weeks of treatment was similar between the two groups. However, significantly greater changes from baseline to 12 weeks were observed in total OABSS, OABSS urgency incontinence score (Q4), IPSS storage subscore (Q2 + Q4 + Q7), and IPSS urgency score (Q4) in the mirabegron group (P = 0.01 for all). According to the extended study, the changes of all efficacy variables from baseline to 26 weeks were similar between both groups. The safety assessment results were also similar between the two groups at 12 and 26 weeks. CONCLUSION A daily 50 mg dose of mirabegron for 12 weeks reduced OAB symptoms in men, and no significant adverse events compared to the placebo group were noted.

Abstract
PURPOSE To identify the prognostic factors related to tumor recurrence and progression in Korean patients with non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS Data were collected and analyzed for 2412 NMIBC patients from 15 centers who were initially diagnosed after transurethral resection of bladder tumor (TURBT) from January 2006 to December 2010. Using univariable and multivariable Cox proportional hazards models, the prognostic value of each variable was evaluated for the time to first recurrence and progression. RESULTS With a median follow-up duration of 37 months, 866 patients (35.9%) experienced recurrence, and 137 (5.7%) experienced progression. Patients with recurrence had a median time to the first recurrence of 10 months. Multivariable analysis conducted in all patients revealed that preoperative positive urine cytology (PUC) was independently associated with worse recurrence-free survival [RFS; hazard ratio (HR) 1.56; p<0.001], and progression-free survival (PFS; HR 1.56; p=0.037). In particular, on multivariable analysis conducted for the high-risk group (T1 tumor/high-grade Ta tumor/carcinoma in situ), preoperative PUC was an independent predictor of worse RFS (HR 1.73; p<0.001) and PFS (HR 1.96; p=0.006). On multivariable analysis in patients with T1 high-grade (T1HG) cancer (n=684), better RFS (HR 0.75; p=0.033) and PFS (HR 0.33; p<0.001) were observed in association with the administration of intravesical Bacillus Calmette-Guérin (BCG) induction therapy. CONCLUSION A preoperative PUC result may adversely affect RFS and PFS, particularly in high-risk NMIBC patients. Of particular note, intravesical BCG induction therapy should be administered as an adjunct to TURBT in order to improve RFS and PFS in patients with T1HG cancer.

Abstract
Purpose: Despite recent improvements, resistance to traditional immunotherapy or chemotherapy is still common in patients with bladder cancer. We constructed an oncolytic virus from herpes simplex virus type II (HSV-2), which selectively targets tumor cells with an activated Ras signaling pathway. We evaluated the antitumor effect of this oncolytic HSV-2 (FusOn-H2) against bladder cancer, and compared with that of a first generation oncolytic virus derived from HSV-1 (Baco-1). Materials and methods: We established bladder tumor at the orthotopic site in C3H/He mice using the MBT-2 cells. Baco-1 or FusOn-H2 was instilled into the bladder through the urethra respectively. Tumor volume and weight were recorded by the end of the experiment. Animal spleens were also collected to determine if any anti-tumor immunity was elicited during virotherapy in this syngeneic bladder cancer model. Results: Two instillations of the oncolytic HSVs into bladder of tumor-bearing mice almost completely eradicated the tumor in majority of tumor bearing mice. The results of tumor-specific cytotoxic T lymphocyte activity assay showed that tumor destruction by oncolytic viruses in vivo, especially by the FusOn-H2, induced potent anti-tumor immune responses. Conclusion: Oncolytic virus derived from HSV-2 has potent anti-tumor activity against bladder cancer. Oncolytic effect of this virus in vivo induces tumor specific cellular immunity that further enhances the overall anti-tumor activity. Translating this novel virotherapy into the clinic could present an alternative intravesical therapy strategy for patients with bladder cancer.

Abstract
Purpose We investigated the impact on prostate-specific antigen (PSA) and prostate volume (PV) of statin medication for 1 year in patients with benign prostatic hyperplasia (BPH). Materials and Methods We retrospectively investigated 791 patients in whom BPH was diagnosed. For analysis, the patients were divided into four groups according to their medications: group A, α-blocker; group B, α-blocker+statin; group C, α-blocker+dutasteride; group D, α-blockers+statin+dutasteride. To investigate changes in serum PSA, PV, and total cholesterol, we analyzed the data at the time of initial treatment and after 1 year of medication. Results After 1 year, group A showed a 1.3% increase in PSA and a 1.0% increase in PV. Group B showed a 4.3% decrease in PSA and a 1.8% decrease in PV. The difference in PV reduction between groups A and B was statistically significant (p<0.001). Group C showed a 49.1% reduction in PSA and a 22.9% reduction in PV. Group D showed a 51.6% reduction in PSA and a 24.5% reduction in PV. The difference in PV reduction between groups C and D was not statistically significant (p=0.762). By use of a multivariate logistic regression model, we found that the probability of PV reduction after 1 year was more than 14.8 times in statin users than in statin nonusers (95% confidence interval, 5.8% to 37.6%; p<0.001). Conclusions Statin administration reduced PSA and PV in BPH patients. This finding may imply the improvement of lower urinary tract symptoms and prevention of cardiovascular disease and chemoprevention of prostate cancer with statin treatment.

Abstract
Background/Aims The red-blood-cell distribution width (RDW) is a newly recognized risk marker in patients with cardiovascular disease, but its role in nonalcoholic fatty liver disease (NAFLD) has not been well defined. The aim of the present study was to determine the association between RDW values and the level of fibrosis in NAFLD according to BARD and FIB-4 scores. Methods This study included 24,547 subjects who had been diagnosed with NAFLD based on abdominal ultrasonography and questionnaires about alcohol consumption. The degree of liver fibrosis was determined according to BARD and FIB-4 scores. The association between RDW values and the degree of fibrosis in NAFLD was analyzed retrospectively. Results After adjusting for age, hemoglobin level, mean corpuscular volume, history of hypertension, history of diabetes, and high-sensitivity C-reactive protein, the RDW values were 12.61±0.41% (mean±SD), 12.70±0.70%, 12.77±0.62%, 12.87±0.82%, and 13.25±0.90% for those with BARD scores of 0, 1, 2, 3, and 4, respectively, and 12.71±0.72%, 12.79±0.66%, and 13.23±1.52% for those with FIB-4 scores of <1.30, 1.31-2.66, and ≥2.67, respectively (P<0.05). The prevalence of advanced fibrosis (BARD score of 24 and FIB-4 score of ≥1.3) increased with the RDW [BARD score: 51.1% in quartile 1 (Q1) vs. 63.6% in Q4; FIB-4 score: 6.9% in Q1 vs. 10.5% in Q4; P<0.001]. After adjustments, the odds ratio of having advanced fibrosis for those in Q4 compared to Q1 were 1.76 (95%CI=1.55-2.00, P<0.001) relative to BARD score and 1.69 (95%CI=1.52-1.98, P<0.001) relative to FIB-4 score. Conclusions Elevated RDW is independently associated with advanced fibrosis in NAFLD.

Abstract
Staphylococcus infection was the most common organism found in infection of athletics, and tuberculosis (TB) was rare. Although genitourinary tuberculosis (GUTB) was the most common subtype of extrapulmonary tuberculosis (EPTB) in the past, it was recently reported to account for less than 0.5% of all patients with EPTB and 1.5% of all patients with pulmonary tuberculosis (TB). And, there are few cases reported about concomitant tuberculous infection of testis and prostate. Pubic pain is a common symptom in soccer player and its cause can be difficult to determine. A 25-yr-old male soccer player presented with persistent pubic pain of unknown origin. Incidentally, right testicular mass was detected on physical examination. Computed tomography revealed a multiple enlarged retroperitoneal lymph nodes. Under the clinical diagnosis of a right testicular tumor, right radical inguinal orchiectomy was performed. And prostate biopsy was performed due to elevated serum prostate specific antigen (PSA). Pathologic examination confirmed concomitant TB of testis and prostate.

Abstract
The incidence of horseshoe kidney is about 1 in 400 cases. The presence of Wilms' tumor with a horseshoe kidney is unusual, and the occurrence of Wilms' tumor in a horseshoe kidney is estimated at 0.4 to 0.9% of all Wilms' tumors. We report the case of a 5-year-old boy who presented with a stage IV Wilms' tumor in a horseshoe kidney. The patient was treated with preoperative chemotherapy followed by surgical resection and adjuvant chemotherapy. This case illustrates the role of preoperative chemotherapy for preserving renal function and aims to highlight the multimodality treatment of Wilms' tumor.

Abstract
Background/Aims We have a limited understanding of the effect of nonalcoholic fatty liver disease (NAFLD) on the development of type 2 diabetes. Methods The study subjects included male who had received biennial medical check-ups between 2005 and 2009 and who had been diagnosed with fatty liver disease. The subjects with sustained NAFLD (FL, n=107) and sustained non-NAFLD (NFL, n=1,054) were followed to determine the development of type 2 diabetes. Results In the FL group, there were more subjects with impaired fasting glucose (IFG), type 2 diabetes and high HOMA-IR than there were in the NFL group during the 5-year follow-up period (32.7 vs. 17.6%, 1.9 vs. 0.3%, 17.9 vs. 5.2% respectively, p<0.05). The FL group showed a higher risk than NFL group for abnormal glucose metabolism as determined using IFG (odds ratio [OR], 2.13; confidence interval [CI], 1.36 to 3.35), type 2 diabetes (OR, 7.63; 95% CI, 1.03 to 56.79) and high HOMA-IR (OR, 3.25; 95% CI, 1.79 to 5.91) and metabolic parameters such as body mass index (OR, 3.35; 95% CI, 1.87 to 6.02), triglyceride (OR, 3.05; 95% CI, 1.92 to 4.86) and fasting blood sugar (OR, 2.18; 95% CI, 1.39 to 3.41). Conclusions Sustained NAFLD appears to be associated with an increased risk for the development of type 2 diabetes and deterioration of metabolic parameters in non-obese, non-diabetic Korean men.

Abstract
PURPOSE Animal tumor models are important for the evaluation of novel therapeutic modalities. Since the initial report of an orthotopic bladder tumor model, several modifications have been proposed to improve the tumor take rate. Here we compared the HCl-pretreated and electrocauterization-pretreated orthotopic murine bladder tumor models. MATERIALS AND METHODS MBT-2 murine bladder cancer cells were transurethrally implanted in the bladder of syngeneic C3H/He mice. The mice were divided into three groups according to pretreatment methods (electrocautery, HCl, and control group) and were subjected to pretreatment before instillation of MBT-2 tumor cells into the bladder. Mice were sacrificed on day 21, and bladders were harvested, weighed, and examined histopathologically. RESULTS The tumor take rate of the control, electrocautery, and HCl groups was 0%, 54%, and 100%, respectively. The tumor take rate of the HCl group was significantly higher than that of the control group (p<0.01) and the electrocautery group (p=0.01). Pathologic reports revealed that all established bladder tumors were high-grade papillary urothelial carcinomas. CONCLUSIONS The HCl pretreatment model was a preferable murine bladder tumor model for evaluating further therapeutic interventions.

Abstract
OBJECTIVES The aim of this study was to compare the efficacy of low (0.2 mg) and intermediate (0.4 mg) dose tamsulosin in treating lower urinary tract symptoms (LUTS). METHODS Patients were treated with low-dose tamsulosin for an initial run-in period of 12 weeks, then divided into two groups based on their clinical improvement. Patients were measured for objective parameters of peak flow rate and postvoid residual urine volume, as well as subjective symptom scores and perceived patient benefit of treatment. The items were then integrated as the LUTS Outcome Score to determine dose increase or maintenance. Overall outcome was determined at 36 weeks. RESULTS One hundred and seventy-four patients were enrolled and started on 0.2 mg tamsulosin treatment. One hundred and fifty-five patients completed the 36-week study. Sixty patients required dose increase to 0.4 mg at the 12th week. Baseline characteristics showed that a patient who would benefit from 0.4 mg dosage had higher age, daytime frequency, and lower peak urine flow rate. Patients receiving both 0.2 and 0.04 mg both showed improved clinical outcome measures. Higher improvement was found in voiding component symptom scores and urine flow rate improvement in patients receiving an increased dose. CONCLUSION Both low- and intermediate-dose tamsulosin are effective treatment regimens. Increasing from low to intermediate dose should follow assessment of both objective and subjective improvements.

Abstract
AIMS To know which MS criteria best predict the presence of NAFLD and the prevalences of metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) diagnosed ultrasonographically among pre-diabetic and diabetic subjects based on three different MS criteria (IDF, ATP III, WHO). METHODS Subjects were screened and those with a fasting serum glucose level ≥100 mg/dL were further tested with a 75 g oral glucose tolerance test. And those who were newly diagnosed as having pre-diabetes or diabetes were evaluated for MS and NAFLD. We compared the risk ratios of NAFLD among three MS criteria using multivariate and multiple logistic regression analyses. RESULTS A total of 1365 subjects (977 males, mean age 48.4±9.5 years) were analyzed. The WHO criteria produced the highest prevalence of MS in both the pre-diabetic (49.8%) and diabetic (58.9%) groups. The IDF criteria produced the highest odds ratio for NAFLD in both pre-diabetic (3.89 [95% CI 2.75-5.51]) and diabetic (5.53 [95% CI 3.21-9.52]) groups. CONCLUSIONS The prevalence of MS depends on the set of diagnostic criteria used. IDF criteria best predicts the presence of NAFLD. The presence of NAFLD should be considered as a component of the diagnostic criteria for MS.

Abstract
OBJECTIVE To determine and compare autonomic dysfunction in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS The subjects were 30-60 years old and had no known systemic disease. Electrocardiographic signals in the patients in the resting state were obtained from 59 patients with CP/CPPS (age 46.5 ± 7.02 years) and 94 healthy subjects (age 48.4 ± 5.96 years), and heart rate variability parameters were compared. RESULTS The standard deviation of the N-N interval (P < .001), square root of the mean squared differences of the successive N-N intervals (P = .004), total power (P = .004), very low frequency (P = .012), and high frequency (P < .001) were lower in the patients with CP/CPPS. However, no significant differences were found in the low frequency and low frequency/high frequency ratios. CONCLUSION Patients with CP/CPPS exhibited lower heart rate variability parameters compared with normal controls, with the exception of low frequency and low frequency/high frequency ratios. Possible differences in autonomic nervous system between those with CP/CPPS and normal healthy subjects could exist and autonomic dysfunction might be 1 of the causes that aggravates CP/CPPS.

Abstract
OBJECTIVE To investigate the effects of conventional and single port laparoscopically assisted vaginal hysterectomy (LAVH) on sexual function in premenopausal women. DESIGN A prospective case-control study. SETTING University teaching hospital. Population. A total of 95 premenopausal women having LAVH from January 2009 to December 2009. METHODS Comparison of 47 premenopausal women who had single port LAVH using trans-umbilical GelPort access (SP-LAVH group) and 48 premenopausal women who had conventional multiport LAVH (conventional LAVH group). MAIN OUTCOME MEASURES Evaluation of sexual function was done prior to and six months after surgery using a validated tool, the female sexual function index (FSFI). RESULTS In terms of women's demographic characteristics and operative results, there was no significant difference between the two study groups, or between pre- and postoperative individual domain scores or total female sexual function index in women who underwent either conventional or single port LAVH. CONCLUSIONS Neither conventional nor single port LAVH affects sexual function in premenopausal women. Women can be counseled that this type of surgery is unlikely to alter sexual function.

Abstract
Purpose The metabolic syndrome (MS) has been accepted as an important cause of benign prostatic hyperplasia (BPH) in old age. However, there are no studies of the influence of MS on prostate volume in relatively young adults. We evaluated the relationship between parameters of MS and prostate volume in men under 50 years of age who visited our health promotion center. Materials and Methods A total of 968 men aged 30 to 49 years were enrolled from March 2009 to June 2010. Prostate volume by transrectal ultrasonography of the prostate, serum prostate-specific antigen, digital rectal examination, urinalysis, and MS-related parameters were investigated. We evaluated the correlations of prostate volume with MS and MS-related parameters. Results Prostate volume was not significantly larger in the MS group (18.4 cc; range: 14.3-23.1 cc) than in the non-MS group (17.8 cc; range, 13.6-21.6 cc). The prostate volumes in subjects with abnormal fasting plasma glucose (FPG) (18.9 cc; range, 14.3-22.7 cc) and abnormal waist circumference (WC) (19.5 cc; range, 15.6-23.7 cc) were significantly larger than those of subjects with normal parameters (16.9 [range, 12.7-20.4] cc and 17.5 [range, 13.3-21.2] cc, respectively; p=0.001). The logistic regression analysis showed the FPG level and WC to have a significantly positive correlation with the prostate volume (odds ratios: 1.441 [95% CI: 1.303-1.643] and 2.305 [95% CI: 1.470-3.614], respectively). Conclusions Groups with abnormal FPG and WC had larger prostate volumes than did normal groups. The abnormal FPG and WC could be more important factors than MS in prostate volume enlargement in relatively young adults.

Abstract
OBJECTIVE To increase vigilance among gynecological surgeons for the presence of accessory polar renal artery (APRA) encountered with transperitoneal systemic laparoscopic paraaortic lymphadenectomy (LPAL). METHODS A retrospective review was conducted on 156 women who underwent LPAL for various gynecologic malignancies between November 2003 and December 2009. RESULTS The median age, parity, body mass index, and number of previous abdominal surgeries, respectively, of the women were 52 years (range, 23-82 years), two (range, 0-7), 24.1 kg/m2 (range, 17.4-35.0 kg/m2), and 0 (range, 0-3). During the study period, we found four women with APRA. There were three cases of right lower APRAs arising from the abdominal aorta, caudal to the inferior mesenteric artery (IMA), terminating at the parenchyma of the lower pole of the right kidney. In the other case, the APRA arose from the abdominal aorta superior to the IMA. There were no vascular complications, such as transection or ligation of the APRA. CONCLUSION It is important for the gynecological oncologic surgeon to have knowledge of retroperitoneal vascular anatomy, experience in laparoscopic surgery, and an accurate surgical technique to avoid vascular injury during LPAL.

Abstract
BACKGROUND/AIMS This study evaluated the relationship between hyperuricemia and nonalcoholic fatty liver disease (NAFLD) by comparing the incidence rates of NAFLD in relation to serum uric acid levels in apparently healthy subjects during a 5-year period. METHODS Among 15,638 healthy Korean subjects who participated in a health-screening program in 2003 and 2008, respectively, 4954 subjects without other risk factors were enrolled in this study. We compared the incidence rates of NAFLD in 2008 with respect to baseline uric acid levels. RESULTS In 2003, serum uric acid levels were categorized into the following quartiles: 0.6-3.9, 3.9-4.8, 4.8-5.9, and 5.9-12.6 mg/dL. The incidence of NAFLD in 2008 increased with the level of baseline uric acid (5.6%, 9.8%, 16.2%, and 20.9%, respectively; p<0.05). Multiple logistic regression analysis demonstrated that hyperuricemia was associated with the development of NAFLD. When compared to the subjects in quartile 1, the odds ratio (OR) for the incidence of NAFLD for quartiles 2, 3, and 4 were 1.53 (95% confidence interval [CI], 1.09-2.16; p=0.014], 1.69 (95% CI, 1.17-2.44; p=0.005), and 1.84 (95% CI, 1.25-2.71; p=0.002), respectively. CONCLUSIONS High serum uric acid levels appear to be associated with an increased risk of the development of NAFLD.

Abstract
The B-cell lymphoma-6 (BCL6) gene was initially identified at a translocation site observed frequently in diffuse large B-cell lymphomas. In the present study, BCL6 mutations at the 5' non-coding region in 47 cases of transitional call carcinoma (TCC) were analysed using polymerase chain reaction-single-strand conformation polymorphism. The results were compared with data obtained previously by immunohistochemical staining for the BCL6 protein. Overall, BCL6 mutations were observed in 44.7% of cases. Mutation of the 5' non-coding region was not correlated with histological grade of the tumour; however, the better the histological grade, the greater the mutation rate of the E1.12 fragment. The BCL6 mutation occurred independently of over-expression of the protein. The BCL6 gene mutation and the protein expression were detectable in a large proportion of TCCs. BCL6 protein over-expression as well as BCL6 gene mutation of the E1.12 fragment may play an important role in the morphological differentiation of TCC.

Abstract
AIM Having better edge enhancement and penetrating power, refractive index radiology is suitable for the imaging of weakly absorbing objects such as tissue specimens. In this study the potential of refractive index radiology was evaluated for the imaging of renal cell carcinoma (RCC) and prostate cancer (PCA). METHODS Specimens were cut in 3 mm and 4 microm thickness for X-ray radiology and hematoxylin and eosin (HE) staining, respectively. Radiographic images of RCC and PCA were obtained using the synchrotron hard X-rays from the 7B2 beam-line of the Pohang Light Source (PLS). The imaging technique applied was phase-contrast radiology based on the refraction enhancement mechanism. The resulting radiographic images were analyzed in correlation with those of optical microscopy. RESULTS Using unmonochromatized hard X-rays, it was possible to obtain images with clear edge enhancement and relatively large field of view (6 cm x 6 cm). Even with overlapping signals from thick samples (more than 700-fold thicker than microscopic images), radiographic images clearly showed histological information of organelles in normal kidney such as glomeruli, tubules, and collecting ducts. Histological information of RCC including tumor subtypes and minute changes such as cystic degeneration could be identified without difficulty. The radiographic images of the prostate were comparable with those of low magnification optical microscopy, providing good visualization of normal microstructures such as adenoma, smooth muscle, and normal glands, or differentiation of tiny tumors from surrounding normal tissues. CONCLUSIONS These results suggest the potential of refractive index radiology to provide a new way of imaging biological tissues with low absorption contrast such as RCC and PCA.

Abstract
OBJECTIVE To measure bone mineral density (BMD) and testosterone levels in patients with non-mosaic Klinefelter's syndrome (KS), as a low BMD is common in hypogonadal men, but little is known about the relationship between BMD and serum testosterone levels in men with KS. PATIENTS, SUBJECTS AND METHODS The study included 40 patients with KS and 20 healthy fertile men recruited as controls. Serum testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were measured by radioimmunoassay. The BMD was obtained at the lumbar spine (L2-4), femoral neck and Ward's triangle, by dual-energy X-ray absorptiometry. RESULTS The serum testosterone level was lower, while FSH and LH were higher, in patients with KS than in the control group (P < 0.001). Patients with KS had a significantly lower mean (sd) BMD at the lumbar spine, femoral neck and Ward's triangle, than the controls, at 0.88 (0.13) vs 1.09 (0.10) (P < 0.001), 0.78 (0.12) vs 0.87 (0.10) (P = 0.006) and 0.65 (0.12) vs 0.76 (0.11) g/cm(2) = 0.001), respectively. There was a linear correlation between all BMD values and serum testosterone levels in men with KS who had a low serum testosterone level. CONCLUSIONS There was a relationship between a lower BMD and testosterone levels in patients with KS. These findings suggest that low testosterone levels cause inadequate bone development and a low BMD in men with KS; therefore, testosterone replacement might be necessary to prevent bone mineral deficiency and future risk of fractures in men with KS who also have low serum testosterone levels.

Abstract
Neopterin is a pyrazino-pyrimidine compound, and is known to be a marker associated with cell-mediated immunity in various diseases. We hypothesized that the levels of serum and urine neopterin would be elevated in renal disease, and would correlate with certain clinical parameters. We evaluated serum and urinary neopterin levels in patients with several renal diseases, including nephrotic syndrome (NS, n=19), chronic renal failure (CRF, n=8), end stage renal disease (ESRD, n=64) and controls (n=22). Serum neopterin was elevated in patients with CRF and ESRD, as compared to controls. Urinary neopterin levels were also found to be elevated in patients with CRF and ESRD, as compared to controls. Serum neopterin levels showed significant positive correlation with age, serum BUN and creatinine levels, and inverse correlation with WBC, hemoglobin, hematocrit, serum albumin and total iron binding capacity. Urine neopterin levels exhibited positive correlation with age and serum creatinine levels, and inverse correlation with WBC, hemoglobin, hematocrit, BUN and serum albumin. In conclusion, increased serum and urinary neopterin levels were found in some patients with renal disease and were correlated with certain clinical parameters.
