Objectives: To develop the use of Thiel soft embalmed human cadavers (TeC) in open radical cystectomy (ORC) training for the first time, to investigate the effect of cadaveric training on surgical trainees' technical skills/performance and to determine how trainees perceive the use of cadaveric workshops. Methods: A 3‐day hands‐on workshop was organised. Ten trainees performed ORC on five TeC, supervised by five experts. Feedback from trainees and mentors was evaluated on a five‐point Likert scale. All procedures were completed in a fully equipped surgical environment and complied with the principles outlined in the Declaration of Helsinki. Results: The workshop participants evaluated the anatomical and manipulation characteristics of the TeC as similar to real‐life conditions. The colour and consistency of the urethra and ureter differed little from those in live patients. The trainees stated that the TeC were beneficial for learning the stages of ORC and urinary diversion (UD), while their self‐confidence increased. In terms of realism, all steps of radical cystectomy (RC) were rated 4 out of 5 or higher on the Likert scale by both trainees and faculty. Conclusions: The use of TeC for RC und UD was perceived as favourable by trainees and faculty. The TeC demonstrated a surprising ability to mimic real‐life anatomy and represent a new and effective surgical training tool. [ABSTRACT FROM AUTHOR]

Objectives To investigate the relationship between single nucleotide polymorphism (SNP) of excision repair cross-complementation group 1 (ERCC1) rs11615 and the safety outcomes of cisplatin-based adjuvant chemotherapy in post-cystectomy bladder cancer patients. Methods This pilot single-center retrospective cohort research study involved 25 patients with muscle-invasive bladder cancer who were admitted to the Urology and Nephrology Center (UNC), Mansoura University, Egypt between January and December 2016. The study tried to reveal the association between SNP rs11615 in ERCC1 gene and the change from baseline characteristics in a median of 96 weeks follow-up in blood, renal, and hepatic biochemical parameters. Results Univariate analysis of the association between rs11615 and post-chemotherapy changes in uric acid and hemoglobin levels showed a statistically significant relationship. Conclusion These findings hint at possible genetic influences in response to chemotherapy, necessitating further research to understand the mechanisms and potential clinical implications. This could lead to personalized treatment plans enhancing patient care and outcomes. [ABSTRACT FROM AUTHOR]

Urothelial bladder carcinoma (UBC) is usually detected during work-up for hematuria. Cystoscopy and/or contrast-enhanced imaging are the gold standard tools for UBC diagnosis, despite limited by being invasive, expensive and low yield in small flat tumors. To assess the diagnostic performance of urine-based DNA methylation of six genes (GATA4, P16, P14, APC, CDH1 and CD99) for UBC detection in patients with hematuria. Voided urine was collected from consecutive patients presented with hematuria for urine cytology and DNA methylation assay of the assigned genes using methylation-specific Polymerase Chain Reaction (PCR). Further assessment by office cystoscopy and imaging with subsequent inpatient cystoscopic biopsy for positive findings was done. The diagnostic characteristics of DNA methylation and urine cytology were assessed based on its capability to predict UBC. We included 246 patients in the study with identified macroscopic hematuria in 204 (82.9%) patients. Positive cytology was found in 78 (31.7%) patients. DNA methylation of GATA4, P16, P14, APC, CDH1 and CD99 genes was identified in 127 (51.6%), 52 (21.1%), 117 (47.6%), 106 (43.1%), 90 (36.6%) and 71 (28.9%) patients, respectively. The sensitivity of the assigned genes for UBC detection ranges from 35% (95%CI: 31–39) to 83% (95%CI: 79–87). Optimal specificity (SP) (100%) was noted for P16, APC and CDH1 genes. While for the other genes (GATA4, P14 and CD99), the SP was 95% (95%CI: 92–98), 96% (95%CI: 92–99) and 97% (95%CI: 93–99), respectively. On multivariate logistic regression analysis, all genes exclusively demonstrated independent prediction of UBC. On receiver operator characteristic (ROC) analysis, all tested genes methylation showed superior area under the curve (AUC) when compared to urine cytology. We have developed a novel urine-based DNA methylation assay for detection of UBC in patients with hematuria with superior diagnostic performance and independent predictive capacity over urine cytology.
