RESUMO
BACKGROUND: Cancer therapy has evolved from non-specific cytotoxic agents to a selective, mechanism-based approach that includes targeted agents and immunotherapy. Although the response to targeted therapies for unresectable hepatocellular carcinoma (HCC) is acceptable with the improved survival, the high tumor recurrence rate and drug-related side effects continue to be problematic. Given that immune checkpoint inhibitor alone are not robust enough to improve survival in unresectable HCC, growing evidence supports the combination of targeted therapy and immunotherapy with synergistic effect. METHODS: Online databases including PubMed, EMBASE, Cochrane Library, and Web of Science were searched for the studies that compared targeted monotherapy with the combination therapy of targeted drug and checkpoint inhibitors in unresectable HCC patients. Eligibility criteria were the presence of at least one measurable lesion as defined by the Response Evaluation Criteria in Solid Tumors (version 1.1) for unresectable HCC patients, an Eastern Cooperative Oncology Group performance status of 0-2, and a Child-Pugh score ≤ 7. Outcome measurements include overall survival (OS), progression-free survival (PFS), and treatment-related adverse event (TRAE). RESULTS: Three phase II/III randomized controlled trials were included in this study. The pooled results showed that combination therapy significantly improved survival than targeted monotherapy, in terms of OS (hazard ratio (HR) = 0.67; 95% confidence interval [CI]: 0.50-0.91) and PFS (HR = 0.58; 95% CI: 0.51-0.67), respectively. In the incidence of grade 3-5 TRAEs, the combination therapy was significantly higher than targeted monotherapy (odds ratio = 1.98; 95% CI: 1.13-3.48). CONCLUSION: For unresectable HCC, combined targeted drug and immunotherapy significantly improved survival compared with targeted monotherapy. However, the incidences of AEs of combinational therapy were higher than targeted monotherapy.

PURPOSE: Combined information on single nucleotide polymorphisms and prostate specific antigen offers opportunities to improve the performance of screening by risk stratification. We aimed to predict the risk of prostate cancer based on prostate specific antigen together with single nucleotide polymorphism information. MATERIALS AND METHODS: We performed a prospective study of 20,575 men with prostate specific antigen testing and 4,967 with a polygenic risk score for prostate cancer based on 66 single nucleotide polymorphisms from the Finnish population based screening trial of prostate cancer and 5,269 samples of 7 single nucleotide polymorphisms from the Finnish prostate cancer DNA study. A Bayesian predictive model was built to estimate the risk of prostate cancer by sequentially combining genetic information with prostate specific antigen compared with prostate specific antigen alone in study subjects limited to those with prostate specific antigen 4 ng/ml or above. RESULTS: The posterior odds of prostate cancer based on 7 single nucleotide polymorphisms together with the prostate specific antigen level ranged from 3.7 at 4 ng/ml, 14.2 at 6 and 40.7 at 8 to 98.2 at 10 ng/ml. The ROC AUC was elevated to 88.8% (95% CI 88.6-89.1) for prostate specific antigen combined with the risk score based on 7 single nucleotide polymorphisms compared with 70.1% (95% CI 69.6-70.7) for prostate specific antigen alone. It was further escalated to 96.7% (95% CI 96.5-96.9) when all prostate cancer susceptibility polygenes were combined. CONCLUSIONS: Expedient use of multiple genetic variants together with information on prostate specific antigen levels better predicts the risk of prostate cancer than prostate specific antigen alone and allows for higher prostate specific antigen cutoffs. Combined information also provides a basis for risk stratification which can be used to optimize the performance of prostate cancer screening.

BACKGROUND/PURPOSE: To evaluate the effectiveness and safety of high-power 120W Greenlight HPS laser (HPS) and compare the results to transurethral resection of the prostate (TURP), and define a subgroup of patients who had better symptom score improvement after HPS. METHODS: One hundred and twenty-five patients who underwent surgery for benign prostatic hyperplasia (BPH) (61 HPS and 64 TURP) were retrospectively followed. Improvements of International Prostate Symptom Score (IPSS), quality of life score (QoL), maximum flow rate (Qmax) and post-void residual (PVR) were assessed at 4 weeks after the procedures. Potential covariates including age, body mass index (BMI), prostate volume (PV) and serum prostate-specific antigen (PSA) were defined and further subgroup analyses were utilized. RESULTS: The HPS group had a significantly higher education level, annual household income and larger prostate size. Compared with TURP, HPS resulted in comparable IPSS, QoL, Qmax and PVR improvements, but shorter hospitalization duration, serum hemoglobin loss and blood transfusion rate. Subgroup analyses showed that men in the HPS group were younger (age<76 years), had higher BMI (≥24kg/m(2)) and greater adjusted IPSS and QoL improvements than men in the TURP group. CONCLUSION: HPS offered adequate effectiveness for symptomatic BPH versus TURP and was advantageous with regard to operative safety. Patients who are younger and have higher BMI may achieve better improvements with HPS than with TURP. Further long-term follow-up study is warranted.

PURPOSE: To evaluate the effectiveness of presence of desmopressin in treating primary enuresis (PE) for children with attention deficit-hyperactivity disorder (ADHD) symptoms. MATERIALS AND METHODS: Children aged from 5 to 12 years with the chief complaint of PE treated with desmopressin were enrolled in pediatric urology clinics. The parent-reported SNAP-IV questionnaire was used to evaluate ADHD symptoms (cut-off value: 90th percentile). Voiding symptoms were assessed by the Dysfunctional Voiding Scoring System (DVSS) questionnaire. The responses to desmopressin were analyzed in children with and without ADHD symptoms. RESULTS: The study sample comprised 68 children; 27 (39.7%) presented with ADHD symptoms and 41 (60.3%) with non-ADHD symptoms. The children collected from a tertiary referral center may explain the high prevalence of ADHD symptoms in the present study. The total DVSS score in the ADHD symptoms group was significantly higher than in the non-ADHD symptoms group (7.72 versus 5.65, P=0.05). In the ADHD symptoms group, there were significantly higher score in the "pee 1-2 times/day" and "can't wait" subscales of DVSS and lower sleep quality based on the Pediatric Sleep Quality questionnaire, as well as significantly lower peak flow rate and voided volume. The responses to desmopressin for enuresis were comparable between children with ADHD and non-ADHD symptoms. CONCLUSIONS: Approximately 39.7% of PE children presented with ADHD symptoms at urologic clinics. PE children with ADHD symptoms had higher risk of daytime LUTS and comparable response to desmopressin treatment for PE. To evaluate ADHD symptoms and daytime voiding symptoms is important in children with PE.

Background: Radiation-induced hemorrhagic cystitis (RHC) is a chronic inflammatory disease in patients undergoing radiation therapy that causes a cluster of symptoms which may have a latent period of months to years. The current non-invasive treatments include drug treatment and hyperbaric oxygen therapy (HBOT), which has been widely applied for RHC so far but with limited evidence. Thus, we conducted a systematic review and meta-analysis to clarify the effects and safety of HBOT for RHC. Methods: A systematic review and meta-analysis were utilized, searching in the databases of Embase, Pubmed, and Web of Science. The primary endpoint of the present study was complete remission of hematuria. The meta-analysis was conducted using a random effects model, and a pooled odds ratio with 95% CI was calculated. Results: A total of 317 studies were searched and fourteen articles with 556 patients were collected. The results showed that a total of 500 patients (89.9%) had symptom improvement, and the pooled results demonstrated that 55% of patients with HBOT had complete remission of hematuria (95% CI 51-59%). Conclusions: A significant improvement of symptoms when treated with HBOT was shown in this meta-analysis for patients with RHC.
RESUMO
AIM: To determine the incidence rate and characteristics in patients with testicular torsion in Taiwan using a nationwide insurance database. METHODS: This study utilizes a subset of national health insurance research database, which contains the data of all paid medical benefit claims over the period 1997-2010 for in 1 000 000 beneficiaries in 2005. We analysed claims data for all male subjects younger than 25 years with the diagnosis of testicular torsion. RESULTS: A total of 86 subjects younger than 25 years with the diagnosis of testicular torsion were included. Among them, 22 (25.6%) underwent orchiectomies and 64 (74.4%) underwent orchiopexies. The estimated incidence of testicular torsion was 3.5 per 100 000 person-years. There are two peaks in the age-specific incidence rates: the first in boys aged 10-14 years (at 7.7 per 100 000 person-years) and the second in male infants aged <1 year (at 7.6 per 100 000 person-years). There was significant difference between orchiectomy and orchiopexy groups in the Insurance fee (p = 0.032). CONCLUSION: The incidence of testicular torsion in Taiwan was similar with previous report in the United States. It is important to improve the medical access to achieve better outcomes of testicular torsion.

BACKGROUND/PURPOSE: Effective stone disintegration by extracorporeal shockwave lithotripsy (ESWL) may depend on patient- and stone-related factors. We investigated predictors of disintegration failure in ESWL for a solitary ureteral calculus. METHODS: From July 2008 to May 2010, 203 patients who underwent ESWL for a solitary ureteral calculus were enrolled. Clinical and radiologic data were collected, and factors related to ESWL failure were analyzed. RESULTS: Fifty-two patients (25.6%) showed ESWL failure, with a mean follow-up of 41 days. Forty patients (19.7%) required retreatment, including 12 who underwent repeat ESWL and 28 who underwent curative ureteroscopy. Patients with ESWL failure had significantly higher body weight, body mass index (BMI), and buttock circumference (BC) than patients for whom ESWL was successful. Univariate analysis showed that stone burden (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.03-1.06) and BC (OR, 1.06; 95% CI, 1.01-1.11) were predictors of ESWL failure, while BMI was a potential predictor with borderline significance (OR, 1.09; 95% CI, 0.99-1.20). Multivariate analysis showed that stone burden (OR, 1.04; 95% CI, 1.03-1.06) was a significant predictor for all patients. On stratifying patients according to the level of ureteral calculi, BC was found to be an independent predictor (OR, 1.35; 95% CI, 1.02-1.80) for ESWL failure for middle/lower ureteral calculi and BMI (OR, 1.47; 95% CI, 1.13-1.91) for upper ureteral calculi. CONCLUSION: Stone burden is the main predictor of ESWL failure for all patients with ureteral calculi. BC and BMI are independent predictors for ESWL failure for middle/lower and upper ureteral calculi, respectively.

BACKGROUND/PURPOSE: Children with attention deficit hyperactivity disorder (ADHD) tend to be more vulnerable to various forms of voiding dysfunction and nocturnal enuresis (NE). We attempt to compare the clinical manifestations and attentional performance between ADHD children with NE and those without NE. METHODS: We consecutively enrolled children diagnosed with ADHD in child and adolescent psychiatric clinics. The questionnaires for evaluation of ADHD symptoms and voiding dysfunction symptoms were administered to all study participants. All participants also received the Test Battery for Attention Performance (TAP) for assessment of attentional function. RESULTS: A total of 53 children were enrolled in this study, comprising 47 boys and six girls. The prevalence rate of NE was 28.3%. Children in the NE group had statistically significant higher dysfunctional voiding symptom score (5.40 ± 3.66 vs.3.16 ± 2.74; p = 0.018) and two subscales of "When I wet myself, my underwear is soaked" (p < 0.001) and "I miss having a bowel movement every day" (p = 0.047). There were no significant differences with regard to all psychiatric evaluations between the NE and non-NE groups. In the TAP test, the NE group showed a significantly shorter reaction time in the domain of inhibitory control, working memory, and auditory sustained attention than the non-NE group. CONCLUSION: Children with ADHD have a high prevalence of NE. ADHD children with NE had a significantly higher dysfunctional voiding symptom score and shorter reaction time in most domains of the TAP test. Further study is needed to discern the impact of NE on the neuropsychological function of ADHD children.

PURPOSE: We clarified correlations between symptoms of attention deficit disorder with hyperactivity and voiding dysfunction in children. MATERIALS AND METHODS: The study sample consisted of 92 boys and 38 girls 4 to 14 years old who presented at pediatric urology clinics with untreated lower urinary tract symptoms. Parents completed the Swanson, Nolan and Pelham-IV scale. Each subject with a combined score in the first 2 subscales (inattention, hyperactivity/impulsivity) at or above the 90th percentile was classified as having symptoms of attention deficit disorder with hyperactivity. All other cases were classified as nonattention deficit disorder. Voiding dysfunction symptoms were assessed by the Dysfunctional Voiding Symptom Scale. Sleep quality was assessed by the Pediatric Sleep Questionnaire. We then analyzed correlations between Dysfunctional Voiding Symptom Scale and symptoms of attention deficit disorder with hyperactivity. RESULTS: The group with symptoms of attention deficit disorder with hyperactivity had significantly higher scores on the Dysfunctional Voiding Symptom Scale overall and in the "cannot wait" subscale compared to the group without attention deficit disorder, as well as poorer sleep quality and lower voiding volumes. Overall Dysfunctional Voiding Symptom Scale scores were significantly correlated with overall Swanson, Nolan and Pelham-IV scale scores and also significantly correlated with each of the 3 Swanson, Nolan and Pelham-IV subscales (inattention, hyperactivity/impulsivity and oppositional defiant). Overall Dysfunctional Voiding Symptom Scale scores and scores on the "cannot wait" and "hurt when pee" subscales were significantly higher for males than for females. CONCLUSIONS: Boys with higher scores of attention deficit disorder with hyperactivity symptoms tend to have higher Dysfunctional Voiding Symptom Scale scores. Lower urinary tract symptoms were significantly correlated with overall Swanson, Nolan and Pelham-IV scores and significantly correlated with each of the 3 subscales. Evaluation of concomitant symptoms of attention deficit disorder with hyperactivity in children with lower urinary tract symptoms is an important clinical concern.

Background: This study investigates the prevalence of lower urinary tract symptoms (LUTS) in school-age children with Attention-Deficit/Hyperactivity Disorder (ADHD) based on hospital-based and population-based cohorts. Methods: The hospital-based sample comprised 42 children with ADHD and 65 without ADHD aged 6−12 years. Voiding dysfunction was assessed by the Dysfunctional Voiding Scoring System (DVSS) questionnaire. We compared the baseline data, DVSS score, and uroflowmetry between the two groups. For the population-based cohort in the national insurance database, we included 6526 children aged 6−12 years, whose claims record included the diagnosis of ADHD, and another 6526 control subjects matched by gender and age. We compared the presence of LUTS diagnosis codes between the two groups. Results: Our results showed that, for the hospital-based cohort, the mean total DVSS score and the proportion of significant LUTS in children in the ADHD group were significantly higher than in subjects in the non-ADHD group. The DVSS subscales showed that the item "I cannot wait when I have to pee" item was significantly higher in the ADHD group (1.62 ± 1.17 vs. 0.90 ± 1.09, p = 0.002). For the population-based cohort, children with ADHD had a significantly higher likelihood of storage symptoms (5.53% vs. 2.91%, p < 0.001) and enuresis (3.28% vs. 1.95%, p < 0.001) compared with those of the no ADHD group. Conclusions: Children with ADHD have a higher prevalence of significant LUTS, especially storage symptoms and enuresis, than children without ADHD. The observed correlations between ADHD and LUTS provided the supporting evidence to evaluate the concomitant voiding dysfunction in children with ADHD.
RESUMO
Acute urinary retention (AUR) is associated with hormone imbalance in men. However, limited studies focused on exploring the complications of AUR in patients with prostate cancer (PC) who receive androgen deprivation therapy (ADT). Therefore, we aim to evaluate the subsequent risk of AUR in ADT-treated PC patients. We collected data from 24,464 male patients who were newly diagnosed with prostate malignancy from a longitudinal health insurance database of catastrophic illness in 2000 to 2008. All PC patients were categorized into 2 cohorts, namely, ADT cohort and non-ADT cohort, based on whether or not the patient receives ADT. The patients were followed up until the occurrence of AUR. Multivariate Cox proportional hazard regression and Kaplan-Meier analysis were performed. After a 12-year follow-up, the incidence rates of AUR were 12.49 and 9.86 per 1000 person-years in ADT and non-ADT cohorts, respectively. Compared with the non-ADT cohort, the ADT cohort had a 1.21-fold increase in AUR risk based on the adjusted model (95% CIâ=â1.03-1.43). In addition, PC patients receiving early ADT treatment within 6 months or receiving only luteinizing hormone-releasing hormone treatment also had significantly increased risk of AUR. ADT was positively associated with AUR risk. PC patients receiving ADT should be informed about the risks of bladder outlet obstruction and AUR, and they may benefit from screening for related risk factors. New guidelines and treatments should be proposed in the future to manage ADT-related lower urinary tract symptoms and reduce the risk of AUR.

(1) Background: A simulation approach for prostate cancer (PrCa) with a prostate-specific antigen (PSA) test incorporating genetic information provides a new avenue for the development of personalized screening for PrCa. Going by the evidence-based principle, we use the simulation method to evaluate the effectiveness of mortality reduction resulting from PSA screening and its utilization using a personalized screening regime as opposed to a universal screening program. (2) Methods: A six-state (normal, over-detected, low-grade, and high-grade PrCa in pre-clinical phase, and low-grade and high-grade PrCa in clinical phase) Markov model with genetic and PSA information was developed after a systematic review of genetic variant studies and dose-dependent PSA studies. This geneâPSA-guided model was used for personalized risk assessment and risk stratification. A computer-based simulated randomized controlled trial was designed to estimate the reduction of mortality achieved by three different screening methods, personalized screening, universal screening, and a non-screening group. (3) Results: The effectiveness of PrCa mortality reduction for a personalized screening program compared to a non-screening group (22% (9%â33%)) was similar to that noted in the universal screening group (20% (7%â21%). However, a personalized screening program could dispense with 26% of unnecessary PSA testing, and avoid over-detection by 2%. (4) Conclusions: GeneâPSA-guided personalized screening for PrCa leads to fewer unnecessary PSA tests without compromising the benefits of mortality reduction (as happens with the universal screening program).

The prospective study is to investigate the associations between serum testosterone levels and LUTS among middle-aged men ≥40 years receiving health check-up. Lower urinary tract symptoms were evaluated by the self-administered International Prostate Symptom Score questionnaire. Serum prostate specific antigen and total testosterone level were checked in all subjects. A total of 1752 men were enrolled into the study. The mean age was 55.6 ± 9.7 years. All study subjects were stratified into low, medium and high testosterone levels by two cut-off, 3.0 and 4.11 ng/mL. We found that testosterone levels were significantly associated with metabolic syndrome and body fat components. Compared to those with low testosterone levels, subjects with high and medium testosterone had a significantly higher IPSS (5.84 ± 5.55 vs 6.71 ± 5.68 and 6.34 ± 5.66, p = 0.032) and storage score (2.76 ± 2.29 vs 3.20 ± 2.49 and 2.90 ± 2.49; p = 0.009), and a more moderate/severe LUTS (IPSS ⧠8) (26.5% vs 35.7% and 29.9%; p = 0.002). Multivariate analyses showed that high vs low testosterone levels (OR, 1.76; 95% CI, 1.26-2.45) and prostate volume â§25 vs <25 mL (OR, 1.38; 95% CI, 1.04-1.82) significantly associated with the presence of moderate/severe LUTS. Pearson correlation analyses showed significantly positive correlations between testosterone level and IPSS in whole study sample (Pearson correlation coefficient, 0.066; p < 0.01) and in the subgroup of moderate/severe LUTS (Pearson correlation coefficient, 0.038; p < 0.05). In conclusion, high testosterone and prostate volume adversely impacted LUTS in our target population.

This study aimed to investigate the risks of thromboembolic vascular disease following androgen deprivation therapy (ADT) administered to prostate cancer (PCa) patients. A total of 24,464 men with newly diagnosed PCa during 2000-2008 were recruited through a longitudinal health insurance database in Taiwan. All PCa patients were stratified into two: ADT and non-ADT groups. Patients with ADT treatment were grouped into three: surgical castration, chemical castration, and anti-androgen alone. The risks of pulmonary embolism (PE), peripheral arterial occlusion disease (PAOD), and deep vein thrombosis (DVT) were assessed in multiple Cox proportional-hazards regression with time-dependent covariates. During the 12-year follow-up period, incidence rates per 1000 person-years in ADT and non-ADT groups were 2.87 and 1.62 for DVT, 1.00 and 0.52 for PE, and 1.03 and 0.70 for PAOD, respectively. The DVT and PE risks were significantly increased in patients receiving combined androgen blockade (CAB) compared with the counterpart ADT non-recipients. After adjusting for potential risk factors, PCa patients receiving CAB had the highest PE risk (HR = 3.11), followed by DVT risk (HR = 2.53). The DVT risk remained elevated throughout the entire duration of chemical castration. However, high PE risk was observed in patients with ≤720-day treatment duration. No association was found between ADT and PAOD risks. Overall, the risks of PE and DVT were considerably heightened in Asian men subjected to CAB for PCa, whereas PAOD risk was unrelated to such treatments.

OBJECTIVE: To investigate the effects of flapless micro-osteoperforation and corticision on the rate of orthodontic tooth movement in rats. MATERIALS AND METHODS: Forty-five 8-week-old male Sprague-Dawley rats were divided into the following groups: micro-osteoperforation and orthodontic force (MOP + F), corticision and orthodontic force (C + F), and orthodontic force only (F, control). The left maxillary first molars were pulled forward with a force of 50 g. Flapless surgical interventions were conducted in the MOP + F and C + F groups. The total duration of the experiment was 6 weeks. Alveolar bone density and the number of osteoclasts were evaluated using microcomputed tomography and histologic examination, respectively. RESULTS: The tooth movement distance was significantly higher in both experimental groups than in the control group. Bone density and bone mineral density decreased in the MOP + F and C + F groups. The number of osteoclasts in the MOP + F and C + F groups was significantly higher than in the control group F. CONCLUSION: The two minimally invasive flapless surgical interventions increased bone remodeling and osteoclast activity and induced faster orthodontic tooth movement for at least 2 weeks in rats. No differences were observed between the outcome of flapless micro-osteoperforation and corticision in the rats.

OBJECTIVES: To investigate the impact of metabolic components and body composition indices on prostate volume (PV) in a population of middle-aged men receiving health check-ups. METHODS: Six hundred and sixteen men receiving health assessments were stratified to large and small prostates based on the cut-off of median PV. Their demographic data, health history, and international prostate symptoms scores (IPSS) were collected. Metabolic components and body composition indices were compared between subjects with large and small prostates. Moreover, the correlations between these parameters and PV were analyzed by multivariate logistic regression. RESULTS: The median PV was 27 mL and mean age was 54.8 years. Subjects with large PV were older (56.5 vs. 52.7 years) and had higher serum prostate specific antigen (PSA) level (1.73 vs. 0.96 ng/mL), higher IPSS score (8.37 vs. 6.16), and higher body fat, body mass, and waist circumference (all p<0.05). In multivariate analysis, age (OR, 2.45; 95%CI, 1.74-3.45), serum PSA (OR, 2.75; 95%CI, 1.96-3.86), waist circumference (OR, 1.45; 95%CI, 1.02-2.07), fatness (OR, 1.47; 95%CI, 1.04-2.09), and body fat mass (OR, 1.43; 95%CI, 1.00-2.03) were significantly correlated with PV of study subjects. In subgroup analysis, raised waist circumference (OR, 1.89; 95%CI, 1.00-3.59) was the independent predictor of PV in subjects with bothersome lower urinary tract symptoms. CONCLUSIONS: Several metabolic components and body composition indices are significantly associated with PV of middle-aged men, including raised waist circumference, fatness, and body fat mass. Raised waist circumference is the only independent predictor of PV in middle-aged men with bothersome LUTS.

To investigate the association between pelvic inflammatory disease (PID) and endometrial cancer (EC).We conducted a nationwide population-based retrospective cohort study, and data were obtained from the National Health Insurance Research Database. We defined 41,065 patients with PID as the PID cohort and 82,130 randomly selected patients as the control cohort through frequency matching by age and index year. PID and EC were diagnosed in accordance with the International Classification of Diseases, Ninth Revision, and Clinical Modification. Cox proportional hazards regression and Kaplan-Meier method were used in the analysis.Incidence rates of 16.1 and 9.6 per 100,000 person-years and mean follow-up durations of 4.84 and 6.63 years were observed in the PID and non-PID cohorts, respectively. After adjusting for potential risk factors, the PID cohort had a 1.79-fold higher risk of developing EC than the non-PID cohort. The incidence of EC increased with age, particularly for those aged >50 years (HR=2.45, 95% CI=1.29-4.65). Higher EC risk was also observed in the PID cohort with hypertension than in the non-PID cohort.The results of this large-scale population-based study showed an increased risk of EC in PID patients, particularly in older patients or those with hypertension. Future large-scale clinical trials are warranted to clarify the function of medication in PID-related EC progression.

OBJECTIVE: To investigate the correlation between prostatic calcification and lower urinary tract symptoms (LUTS) in a sample of middle-aged men receiving health checkups. METHODS: Subjects aged 40 years or older who voluntarily underwent transrectal prostate ultrasound (TRUS) and fulfilled International Prostate Symptoms Score (IPSS) as part of their medical checkup were enrolled in this study. The prostatic calcification grading and prostate volume (PV) were measured by TRUS. The medical history, demographics, and metabolic markers were also evaluated. Logistic regression was used to analyze the correlation between prostatic calcification and LUTS. RESULTS: A total of 604 men were enrolled as study subjects. The prostatic calcification grading was significantly associated with age and PV instead of metabolic markers. Compared to the nonprostatic calcification group, the moderate/marked prostatic calcification group had a significantly higher age-adjusted IPSS (8.69 vs 6.87, P <.01), quality of life (QOL) score (2.57 vs 2.17, P <.01), storage score (3.74 vs 3.06, P = .01), voiding score (4.95 vs 3.72, P <.01), and more maximum flow rate <15 mL/sec (40.4% vs 24.5%, P <.01). Prostatic calcification grading was positively correlated with age-adjusted IPSS, QOL, voiding, and storage scores (all P for trend <.05). Further multivariate analysis indicated that moderate/marked prostatic calcification was an independent risk factors for moderate to severe LUTS (odds ratio [OR] = 1.68, P = .02). CONCLUSION: Prostatic calcification worsened IPSS, QOL, storage, voiding symptoms, and maximum urine flow (Qmax) in middle-aged men receiving a health checkup. Moderate/marked prostatic calcification was an independent risk factor for moderate to severe LUTS.

OBJECTIVE: To investigate the frequency and characteristics of newly diagnosed vesicoureteral reflux (VUR) in children younger than 18 years based on a nationwide database in Taiwan. METHODS: The present study utilizes a subset of the Taiwan's National Health Insurance Research Database, known as the Longitudinal Health Insurance Database 2005, which contains the data of all paid medical benefit claims over 1997-2007 for a subset of 1,000,000 beneficiaries randomly drawn from the population of 22.72 million individuals during any part of the 2005 calendar year. Our analysis includes the data of all pediatric patients with the diagnosis of VUR. RESULTS: A total of 738 subjects with VUR diagnosis were identified, including 412 (55.8%) boys and 326 (44.2%) girls. The peak age of VUR occurrence was the first year for males and 1-4 years for females. Approximately 49.7% of all subjects presented with urinary tract infection (UTI); moreover, there were significant differences between genders concerning the presence of UTI (RR = 0.8; p = 0.002). The occurrence rate of VUR in the pediatric population ranged from 2.63 in 1998 to 3.94 in 2003 per 10,000 children during 1998-2005. The frequency of newly-diagnosed VUR in the pediatric population was significantly correlated with urbanization levels of residence. CONCLUSION: The nationwide, population-based study of pediatric VUR shows there were gender differences in age distribution and presence of UTI. Further studies are warranted to clarify the correlations between urbanization level of residence and occurrence of VUR.

The objective of this study is to evaluate the effects of solifenacin on double-J stent-related symptoms following uncomplicated ureterosocpic lithotripsy (URSL). A total of 70 patients who underwent double-J ureteral stent insertion following URSL were consecutively recruited and received solifenacin postoperatively. Another 70 age- and sex-matched subjects without solifenacin therapy were enrolled as a control group. The clinical data including stone and stent characteristics were collected. All subjects completed the brief-form Ureteral Symptom Score Questionnaire (Chinese-version) to assess the lower urinary tract symptoms, stent-related body pain and hematuria 2 weeks after operation. The severity of stent-related symptoms was compared between two groups. The mean age was 53.8 in solifenacin group and 53.4 years in the control group (p = 0.87). The stone characteristics, stent size, position and curl completeness were similar in both groups. Compared to the control group, solifenacin group had significantly lower total symptom score, urgency and urge incontinence scores. As for stent-related body pain, solifenacin group had significantly less flank, abdominal, urethral pain and hematuria scores (all p < 0.05). The solifenacin versus control group showed significant benefits in lower urinary tract symptoms, stent-related pain and hematuria in both genders (all p < 0.05). Four subjects encountered minor adverse events (5.7 %) and one had urinary retention (1.4 %) in solifenacin group. For patients undergoing URSL and double-J stent indwelling, postoperative solifenacin use was effective and well-tolerated for the treatment of lower urinary tract symptoms, stent-related body pain and hematuria irrespective of genders.
