Unlabelled: The current study aimed to evaluate short- and long-term complication rates and functional outcomes in a substantial cohort of patients undergoing ileal ureter interposition at two high-volume medical centres.

Materials And Methods: A retrospective single-arm analysis was conducted on patients who underwent ureter reconstruction using ileum between 2003 and 2022 at the University Clinic of Cologne and the National Cancer Institute of Ukraine. Data on aetiology, surgical techniques, pre- and postoperative kidney function changes, readmission rates and complication management were collected.

Article Synopsis
  • The study aimed to identify key factors influencing the choice of surgical treatment for patients with localized Renal-Cell Carcinoma (RCC) using clinical and nephrometry data.
  • It involved a retrospective analysis of patients who underwent surgery for localized RCC between 2010 and 2017 and used multivariate predictive modeling to assess risks associated with surgical options.
  • Results indicated that the risks for partial nephrectomy (PN) were linked to remaining functioning kidney tissue volumes for polar and lateral tumors, while tumor size was the main factor for medial tumors, with the predictive model showing high sensitivity (95.2%) and specificity (95.4%).

Purpose: This study aimed to estimate the difference between peripheral and central small renal lesions in terms of their oncologic potential.

Methods: Cross-sectional retrospective analysis of patients with small renal masses (T1a) who underwent surgical treatment between January 2008 and July 2019 at the affiliated hospital. Only patients with ccRCC pathology were included.

In this study, we investigated the relationship between the tumor immune microenvironment (TIME), histological differentiation and hypoxia in patients with muscular-invasive urothelial carcinomas (MIUC) after radical cystectomy. Forty-two cases of pT2-3N0M0 MIUCs underwent clinical, histological and immunohistochemical evaluation by counting CD8+, FOXP3+, CD68+, CD163+ cells and polymorphonuclear leukocytes (PMN) in intra-tumoral and peritumoral areas, assessing PD-L1 and GLUT1 expression for defining the impact of tumor immune contexture on patients' outcomes. Five-year survival rates and overall survival were calculated.

Purpose Of Review: Percutaneous biopsy has an emerging role in the diagnosis and management of small renal masses. The increasing importance of percutaneous biopsy is related to both a better understanding of the natural history of these tumors as well as new developments in treatment strategies.

Recent Findings: We discuss the emerging role of biopsy in the current practice setting.

Objective: Small renal mass is a new distinct clinical entity. Detection of these tumors has increased with increased use of imaging.

Conclusion: We know that a proportion of these tumors are not renal cell carcinoma, and imaging-guided biopsy is being increasingly used for treatment planning.
