Objectives: Chemokines are inflammatory mediators directly involved in immunological mechanisms that mediate alloimmune responses; recently, gene expression analysis studies have aroused great interest in the field of transplantation. We aimed to evaluate the predictive role of chemokine gene expression in rejection in renal transplant patients.

Materials And Methods: Our study included 91 patients who underwent living-related renal transplant.

Article Synopsis
  • * Surveys conducted among healthcare providers and patients revealed that only a minority of providers regularly offer RTB, even though most acknowledge its influence on management decisions.
  • * Barriers to RTB implementation include limited availability, concerns about treatment delays, and a lack of strong evidence on the benefits of RTB, highlighting the need for further research to improve its use in kidney cancer management.

Background And Objective: The role of cytoreductive nephrectomy (CN) in the treatment of metastatic renal cell carcinoma (mRCC) has been called into question on the basis of clinical trial data from the tyrosine kinase inhibitor (TKI) era. Comparative analyses of CN for patients treated with immuno-oncology (IO) versus TKI agents are sparse. Our objective was to compare CN timing and outcomes among patients who received TKI versus IO therapy.

Article Synopsis
  • - This multi-institutional study aimed to investigate the prognostic impact of histomorphological subtyping in patients with nonmetastatic papillary renal cell carcinoma (papRCC) who underwent curative surgery, involving 1,086 patients categorized into two subtypes.
  • - Results showed that patients with type 2 papRCC were generally older, had larger tumors, and exhibited poorer survival rates, with lower 5-year recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) than type 1 patients.
  • - While type 2 was a significant predictor for RFS and CSS, it had no significant impact on OS, highlighting the need for further understanding of how these

Context: The superiority of off-clamp robot-assisted partial nephrectomy (RAPN) over the on-clamp technique has recently been questioned by randomized controlled trials comparing the two techniques.

Objective: To systematically review the recent literature and perform a quantitative synthesis of data on the comparison of off-clamp versus off-clamp hilar control during RAPN.

Evidence Acquisition: A systematic search was performed in the PubMed, Embase, Web of Science, and Scopus databases for studies comparing off-clamp versus on-clamp RAPN in terms of perioperative and functional outcomes.

Article Synopsis
  • This research aims to enhance the understanding of clear-cell renal cell carcinoma (ccRCC) with venous tumor thrombus (VTT) to better select candidates for additional therapy based on their recurrence risk.
  • The study retrospectively analyzed data from 604 patients with nonmetastatic ccRCC, finding that discrepancies in tumor grade between the primary tumor and VTT significantly influenced disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS).
  • Incorporating tumor grade discrepancy into predictive models improved their accuracy, indicating that this information can lead to more personalized and effective treatment strategies for patients.

Article Synopsis
  • Renal cell carcinoma (RCC) presents diverse histopathological features, complicating accurate diagnosis and prognosis, prompting a review of recent AI advancements in pathology to improve analysis accuracy and efficiency.
  • AI techniques are showing promise in effectively identifying and classifying RCC features, which can improve diagnosis, grading, and prognosis prediction while potentially reducing costs and the workload for pathologists.
  • Despite these benefits, challenges like standardization, performance benchmarking, and integration into clinical practices remain; developing clear methodologies and validation processes is essential for the successful adoption of AI in RCC pathology.

Renal cell carcinoma (RCC) incidence has doubled over the past few decades. However, death rates have remained stable as the number of incidental renal mass diagnoses peaked. RCC has been recognized as a European health care issue, but to date, no screening programmes have been introduced.

Article Synopsis
  • * Research indicates that outcomes of SP-robotic PN are comparable to traditional multi-arm robotic surgery, with some studies showing less postoperative pain and overall lower complexity in treated renal masses.
  • * Further prospective studies are needed to evaluate long-term effectiveness and safety, as current data suggests SP-robotic PN is feasible and safe, though cost-effectiveness remains unstudied.

Renal medullary carcinoma (RMC) is a rare form of renal cell carcinoma that has a poor prognosis. It is known to be associated with sickle cell trait or disease, although the exact underlying mechanisms are still unclear. The diagnosis is made through immunochemical staining for SMARCB1 (INI1).

Article Synopsis
  • The updated EAU Guidelines recommend adjuvant pembrolizumab for high-risk operable clear cell Renal Cell Carcinoma (ccRCC) but raise concerns about potential overtreatment and undertreatment of patients based on their risk levels.
  • The review highlights challenges in accurately identifying high-risk tumors due to interobserver variability among pathologists and discusses the need for better prognostic assessment systems.
  • It suggests that molecular biomarkers may improve patient prognostication in the future by helping to better identify those with a more severe prognosis.

Clear cell Renal Cell Carcinoma (ccRCC) is among the 10 most common cancers in both men and women and causes more than 140,000 deaths worldwide every year. In order to elucidate the underlying molecular mechanisms orchestrated by phosphorylation modifications, we performed a comprehensive quantitative phosphoproteomics characterization of ccRCC tumor and normal adjacent tissues. Here, we identified 16,253 phosphopeptides, of which more than 9000 were singly quantified.

The aim of this study is to assess the extent of the increased intracranial pressure resulting from lateral decubitus and 45° downward positioning using sonographic optic nerve sheath diameter (ONSD) in patients undergoing laparoscopic transperitoneal nephrectomy. In addition, we evaluated the effect of the carbon dioxide pneumoperitoneum (COPP) on ONSD. Twenty-four adults were enrolled in this prospective observational study.

Objective: The role of lymph node dissection (LND) is still controversial in patients with renal cell carcinoma undergoing surgery. We aimed to provide a comprehensive review of the literature about the effect of LND on survival, prognosis, surgical outcomes, as well as patient selection and available LND templates.

Methods: Recent literature (from January 2011 to December 2021) was assessed through PubMed and MEDLINE databases.

Objective: No standard strategy for diagnosis and management of positive surgical margin (PSM) and local recurrence after partial nephrectomy (PN) are reported in literature. This review aims to provide an overview of the current strategies and further perspectives on this patient setting.

Methods: A non-systematic review of the literature was completed.

Quadratus lumborum block (QLB) is a new fascial plane block that may be helpful for laparoscopic surgeries. In this present study, we aim to evaluate the analgesic efficacy of QLB in laparoscopic living related donor nephrectomy (LLRDN) applied continuously via a catheter that was placed under laparoscopic vision by the surgeon. Following the approval of the Clinical Research Ethics Committee of Istanbul University, Istanbul Medical Faculty (2019/1552), 9 study (Group QLB) and 26 control (Group M) patients that underwent LLRDN were enrolled in this retrospective study.
