Our study aims to evaluate the incidence of BPH in Testicular Cancer (TCa) survivors, focusing on the impact of chemotherapy and post TCa diagnosed hypogonadism. We conducted a retrospective cohort analysis of US veterans diagnosed with TCa between 1990 to 2021, using the Veterans affairs database. BPH was defined using International Classification of Diseases (ICD) codes, Current Procedural Terminology (CPT) codes, or a 6-month prescription of medications. Associations with BPH were analysed, stratifying the cohort by receipt of chemotherapy and presence of hypogonadism. Multivariable cox regression models were used to determine statistical significance (p-value <0.05). Our cohort included 2038 TCa survivors with a median age at diagnosis of 41 years. On multivariable cox regression analysis, receipt of chemotherapy was not significantly associated with incidence of BPH (p-value= 0.13). When stratified by diagnosis of hypogonadism prior to BPH, no significant associations were found on univariable (p=0.81) as well as multivariable (p=0.65) analyses. In the multivariable model, age at diagnosis was significantly associated with an increased incidence of BPH (Hazard ratio: 1.06, p<0.001). Our findings demonstrate that age is a significant factor associated with development of BPH in this population, while suggesting that chemotherapy for TCa and hypogonadism might not substantially alter the development of BPH.","PeriodicalId":501140,"journal":{"name":"medRxiv - Urology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142248649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incidence of synchronous metastatic PCa in Taiwan is higher than U.S. and Europe. We aim to present the latest life expectancy (LE), loss of LE, and lifetime cost associated with PCa in Taiwan. The PCa data are based on Taiwan Cancer Registry and National Health Insurance Database. Total 30,207 new cases of PCa were recorded during 2008-2019 nationwide. LE, estimated loss of LE and lifetime cost were stratified by age, cancer stage, Gleason score, grade group and serum PSA level at diagnosis. We compared LE and healthcare cost outcomes between synchronous metastatic PCa patients in 3 age groups. Among the 30,207 new cases, the low to intermediate risk groups, high-risk groups, and regional and metastatic PCa accounted for 54.1%, 13.2%, and 32.6% of cases, respectively. A considerable proportion of synchronous metastatic PCa was noted in Taiwan when compared with the U.S. For synchronous metastatic PCa, the highest LE is 9.22 years for ages 20-64 years, followed by ages 65-74 (8.29 years) and ages 75-89 years (4.58 years). The loss of LE in the three groups is 13.63, 6.75, and 3.87 years, respectively. The healthcare cost of synchronous metastatic PCa in all age groups is higher than the average cost for PCa patients in Taiwan. This study provides real-world evidence to support health care policy-making and clinical decisions regarding PCa. Due to the high proportion of synchronous metastatic PCa in Taiwan, the findings of this analysis emphasize the importance of early detection of PCa, which can save LE and decrease the total cost burden on the healthcare system.","PeriodicalId":501140,"journal":{"name":"medRxiv - Urology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OAB was defined as an urgency score of ≥2 points and a total score of ≥3 points based on the Overactive Bladder Symptom Score. OAB severity was categorized as mild (total score, ≥5 points) or moderate-to-severe (total score, 6–15 points).

Initial penile size, BMI, and other growth parameters were measured, with biannual follow-ups extending three years post-bone fusion to evaluate growth rates and influential factors.\u0000Results: Initial mean stretched penile length (SPL) was 3.22 ± 0.21 cm. Significant increases in penile size were observed across all intervals, with the highest growth rates occurring between the first- and second-years post-fusion. BMI emerged as the most significant predictor of penile growth, while initial SPL was the least influential factor. By the third-year post-fusion, all subjects achieved penile lengths within the normal range.\u0000Conclusion: Our findings indicate that most untreated micropenis patients attain normal penile size by adulthood, highlighting the importance of monitoring growth rates rather than focusing solely on initial penile size.

Methods: A systematic literature search was conducted in PubMed, Embase, Cochrane Library, and Web of Science databases from January 2009 to December 2023. Studies were selected based on predefined inclusion criteria. Data extraction and quality assessment were performed independently by two reviewers. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model. Heterogeneity was assessed using the I statistic and Q test. For the assessment of certainty were used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to assess the certainty of evidence for each outcome. The GRADE approach evaluates evidence based on five domains: risk of bias, inconsistency, indirectness, imprecision, and publication bias. Each domain can lead to downgrading the certainty of evidence by one or two levels. The overall certainty of evidence was classified as high, moderate, low, or very low. Results: This updated meta-analysis of prospective studies provides robust evidence that ED was found to be an independent risk factor for CVD outcomes, including coronary artery disease, stroke, and cardiovascular mortality. Clinicians should consider early identification and management of ED, such initiative has great potential to improve cardiovascular risk and using it as stratification criteria would help CVD prevention strategies in men.

The PSA test is commonly used in prostate cancer screening, however its high rate of false-positive results causes unnecessary mental suffering, expensive examination costs, physical injury and other adverse consequences. Therefore, there is an urgent need to find a convenient, cost-effective and non-invasive diagnostic method to reduce the false-positive rate of PSA. This study aimed to assess the diagnostic value of YiDiXie™-SS in PSA-positive patients.\u0000Patients and methods: The study finally included 465 subjects with positive PSA test (prostate cancer group, n=292; BPH group, n=173). Remaining serum samples from the subjects were collected and tested with YiDiXie™ all-cancer detection kit. The sensitivity and specificity of YiDiXie™-SS were evaluated respectively.\u0000Results: The sensitivity of YiDiXie™-SS for the malignant group was 100% (95% CI: 98.7% - 100%; 292/292), with a false negative rate of 0 (95% CI: 0 - 1.3%; 0/292). The specificity of YiDiXie™-SS for the benign group was 57.2% (95% CI: 49.8% - 64.4%; 99/173), with a false positive rate of 42.8% (95% CI: 35.6% - 50.2%; 74/173). This means that YiDiXie™-SS reduces the false positive rate by 57.2% (95% CI: 49.8% - 64.4%; 99/173) with essentially no increase in malignancy leakage.

Therefore, the goal of this study was to identify and quantify physiological, demographic, and stimulation factors that significantly affect EAS recruitment in participants receiving pudendal neuromodulation for treatment of lower urinary tract symptoms.\u0000Methods: Demographic and diagnostic information were collected from participants upon entry to the study. MRI and CT were used to capture patient pudendal nerve anatomy and register the location of the implanted lead. EAS activation by pudendal nerve stimulation at different amplitudes and pulse widths was recorded during neurostimulator lead implantation in the operating room. Linear mixed modeling was used to quantify the impact each variable had on EAS recruitment in the sixteen enrolled participants.\u0000Results: Participant sex, age, and BMI did not significantly affect EAS recruitment with pudendal nerve stimulation. Participant diagnoses had significant relationships to EAS recruitment, likely due to unbalanced group sizes. A pulse width of 210 μs required significantly less current than 60 μs (p = 0.005) to activate the EAS at threshold and significantly less charge than 450 μs (p = 0.02) to activate the EAS at threshold. Increased distance between the stimulating electrode and the pudendal nerve decreased the magnitude of the EAS response (p = 0.0011) and increased EAS activation threshold (p &lt; 0.001).\u0000Conclusions: Of the three tested pulse widths, 210 μs requires the least charge and is a good choice for stimulation. The distance between the electrode and pudendal nerve plays an important role in EAS and pudendal nerve recruitment and minimizing this distance should be a priority during lead implantation.","PeriodicalId":501140,"journal":{"name":"medRxiv - Urology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
