As an antimitotic agent, paclitaxel functions by inhibiting cellular proliferation and migration. The objective of this study is to assess the safety and efficacy of this DCB in managing bulbar urethral strictures. Methods: This study is a retrospective study, involving 19 patients who underwent treatment with DCB for bulbar strictures. Patients' characteristics, preoperative and postoperative maximum flow rates (Qmax), and the duration until recurrence were recorded. Postoperative complications were also noted. Results: Success was achieved in 15 out of 19 patients (78.9%) with a median follow up period of 352 days. The mean maximum urine flow rate preoperatively was 5 mL/s (with a range of 4.00-6.50 mL/s). Subsequent mean flow rates at 3 months, 6 months, 12 months, and 24 months post-treatment were 32 mL/s, 32 mL/s, 24 mL/s, and 20 mL/s, respectively. Notably, there was no recurrence among the 7 patients without previous surgical interventions (47%, P-value .01). The mean duration of stricture-free survival following surgery was 648 days (approximately 21.6 months) (95% CI 500.4-700.2). Importantly, no complications were reported throughout the study. Conclusion: The use of DCB for managing bulbar urethral stricture demonstrated a success rate of 78.9%. Patients without a history of urethral surgery exhibited significantly improved treatment outcomes. Furthermore, the study reported no significant complications associated with the use of DCB.","PeriodicalId":101337,"journal":{"name":"Urology research & practice","volume":"51 2","pages":"66-69"},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12208927/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies suggest a potential role of the endothelin (ET) system, particu- larly ET receptors A (ETAR) and B (ETBR), in male reproductive physiology. Moreover, antiestrogens such as tamoxifen and clomiphene, which are commonly used empiri- cally in this context, may influence ET signaling pathways. However, the relationship between ET receptor expression and specific subtypes of male infertility remains poorly understood. Methods: Semen samples were collected from 56 men: 15 fertile controls with normo- zoospermia and 41 infertile men with abnormal semen parameters, including 22 with OAT syndrome and 19 with isolated teratozoospermia. Men with identifiable female- factor infertility were excluded. Seminal ETAR and ETBR expression were analyzed using immunofluorescence microscopy, Western blotting, enzyme-linked immunosor- bent assay (ELISA), and flow cytometry. Results: The ETAR expression was significantly reduced in infertile men compared to fertile controls (P < .05). The ETBR was undetectable in all samples from patients with OAT syndrome. Notably, 2 distinct ETAR expression profiles were observed within the OAT group: one subgroup with ETAR levels comparable to controls and another with markedly diminished expression, indicating potential phenotypic heterogeneity within OAT syndrome. Conclusion: Altered ETAR expression and the absence of ETBR in men with idiopathic infertility, particularly those with OAT syndrome, highlight a potential role for ET sig- naling in male reproductive dysfunction. Stratification based on ETAR expression may support individualized therapeutic strategies, including ET-targeted or antiestrogen- based therapies, to improve fertility outcomes in this population.","PeriodicalId":101337,"journal":{"name":"Urology research & practice","volume":"51 1","pages":"27-32"},"PeriodicalIF":0.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12128351/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NSC632839 is a dual deubiquitination and desumoylation inhibitor. The desumoylation enzyme SENP2 is one of the targets of NSC632839. This study aimed to evaluate NSC632839 as an antiproliferative agent in prostate cancer (PCa). Methods: The IC50 values for NSC632839 were determined in PCa cell lines PC3 and LNCaP and normal fibroblast cells CCD-1072Sk by crystal violet staining. The colony- formation ability of PC3 and LNCaP cells upon NSC632839 treatment was evaluated by a 2D colony-formation assay. The expression level of SENP2 and its correlation with androgen receptor (AR) were investigated in PCa tissue samples using publicly avail- able datasets. Results: The IC50 values of NSC632839 were 3.1, 1.9, and 17.7 for LNCaP, PC3, and CCD- 1072Sk, respectively. In this IC50 concentration, NSC632839 completely abolished the colony-formation ability of PC3 cells. The expression level of SENP2 was elevated in metastatic PCa tissue samples and was correlated with the AR. Conclusion: NSC632839 was an antiproliferative agent in PCa cells at low doses.

The staining intensity was semi- quantitatively analyzed using a histological scoring system. Results: Microvessel density was significantly higher in the inner prepuce than the outer prepuce in both cases and controls (P < .05), suggesting a potential advantage of inner prepuce tissue in hypospadias repair. Conversely, VEGFR levels were significantly higher in the outer prepuce in cases (P < .05), indicating different healing potentials between these layers.

This study compares postoperative uro- logical infection rates between supine and prone PCNL and identifies associated risk factors. Methods: A retrospective study was conducted on 290 patients who underwent PCNL between January 2014 and August 2023 in the Thammasat University Hospital. Patients were allocated into 2 groups in a 1 : 2 ratio, with 87 patients in the supine group and 203 patients in the prone group.

Participants were given the Androgen Deficiency in the Aging Male (ADAM) and 36-Item Short Form Health Survey questionnaires, and underwent labs including testosterone, follicle-stimulating hormone (FSH), luteinizing hormone, and estradiol levels.Results: Of the 651 male trainees, 27 residents were interested in participating for a response rate of 4.1%. Sixty-seven percent (18/27) completed the surveys and 22% (6/27) completed lab work. Two-thirds of the participants who completed the lab work had total testosterone levels below 400 ng/dL, and half of the participants scored positively on the ADAM questionnaire. A total of 44.4% of participants reported that their health was worse compared to a year prior.Conclusion: Male resident physicians are an at-risk population for symptoms and signs of hypogonadism. This population may benefit from screening and interventions aimed at reducing the impact of hypogonadism. The findings of this study underscore the need for further research to confirm these results and explore potential interventions.","PeriodicalId":101337,"journal":{"name":"Urology research & practice","volume":"50 6","pages":"351-354"},"PeriodicalIF":0.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12015748/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144061441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
