Hilar clamping is typically used in partial nephrectomy to control hemorrhage, which may damage the renal tissue under warm ischemia conditions. The purpose of this study was to evaluate waterjet technology in partial nephrectomy without renal hilar vascular control in a porcine model. Bilateral partial nephrectomy using waterjet was performed in 8 pigs (16 kidneys: 8 for wedge resections, 8 for pole resections). The operations were performed successfully in all animals. The mean dissection time was 30.6 ± 2.9 minutes for pole resections and 36.5 ± 3.5 minutes for wedge resections. The mean blood loss was 51.6 ± 11.7 mL for pole resections and 38.7 ± 9.2 mL for wedge resections. The novel waterjet technique provided precise and effective hydrodissection of the kidney, avoiding damage to the vascular structures or collecting system.

Novel model of the region of interest modified Mayo Adhesive Probability score.

Department of Urology, National Cancer Center Hospital East, Chiba, Japan.
Purpose: To evaluate the association between the newly developed region of interest (ROI)-modified Mayo Adhesive Probability (MAP) score, in which stranding was re-evaluated by computed tomography (CT) number, for predicting operation time in robot-assisted partial nephrectomy (RAPN).
Methods: The study participants were 119 patients who underwent transperitoneal RAPN. With regard to stranding, ROIs were evaluated, and the mean CT numbers were assigned a score ranging from 0 to 3.
Introduction: Nivolumab can cause various immune-related adverse events; it rarely induces Vogt-Koyanagi-Harada-disease-like uveitis. Vogt-Koyanagi-Harada-disease is reported to be closely associated with human leukocyte antigen-DR4.
Case Presentation: A 68-year-old man with metastatic renal cancer underwent nephrectomy.
Introduction: Renal artery pseudoaneurysm is a rare yet serious complication following percutaneous nephrolithotomy, especially in patients with solitary kidneys. Effective management is crucial to prevent further renal damage.
Case Presentation: We report a case of a 41-year-old male with a solitary kidney who experienced gross hematuria and renal insufficiency 3 months after percutaneous nephrolithotomy.

To investigate the potential association between body mass index (BMI) and the clinicopathological features of patients with clear cell renal cell carcinoma (ccRCC). We retrospectively analyzed data from 2541 patients who underwent partial or radical nephrectomy for renal masses between 2013 and 2023 in a single institution. Patients were divided into normal-weight, overweight, and obese groups based on the Chinese BMI classification.

Purpose: Immune Checkpoints Inhibitors (ICI) have changed the therapeutic landscape of metastatic renal cell carcinoma first-line treatment with complete response (CR) at metastatic sites observed in 10 to 15% of cases. Delayed nephrectomy could be discussed for patients having a clinical benefit from immunotherapy-based treatment. However, it is unclear whether prior immunotherapy exposure adversely influences the complexity of surgery.
