Introduction: Surgery for osseous metastases seems to improve the patients with renal cell carcinoma. The goal of this study is to evaluate the efficacy and safety of surgery for osseous metastases from renal cell carcinoma.
Materials: We performed 21 surgery for osseous metastases in 13 patients who have been treated for metastatic renal cell carcinoma at one institution between 2001 and 2007. The surgical procedure included curetage with cementing and or internal fixation, in bloc resection or surgical decompressive procedure. Disease-free and overall survival was calculated using Kaplan-Meïer analysis.
Results: The overall patient survival rate at one year was 84%. The overall median survival time was 23months (IC95%; 16,9-78,1%). The disease-free survival was 19 months (IC95%: 26,7%-80,9%) after surgery. Positive margins were observed in 9 patients (R2) and negative margins in 8 patients (R0). R0 and R2 resections have no impact on local relapse. Minor complications occurred in two patients. There was no intra- or postoperative hemorrhage.
Conclusion: Surgery of osseous metastases is safe and effective and seems to improve outcomes of metastatic renal cell carcinoma.

Focal segmental glomerulosclerosis (FSGS) is the morphologic manifestation of a spectrum of kidney diseases that primarily impact podocytes, cells that create the filtration barrier of the glomerulus. As its name implies, only parts of the kidney and glomeruli are affected, and only a portion of the affected glomerulus may be sclerosed. Although the diagnosis is based primarily on microscopic features, patient stratification relies on clinical data such as proteinuria and etiological criteria.

Clear cell renal cell carcinoma (KIRC) is the most prevalent subtype of renal cell carcinoma (RCC), accounting for 70% to 80% of all RCC cases. The CRYAB (αB-crystallin) gene is broadly expressed across various human tissues, yet its role in KIRC progression remains unclear. This study aims to elucidate the function of CRYAB in KIRC progression and to assess its potential as a biomarker for early diagnosis, therapeutic targeting, and prognosis.

Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

Aim: To study the effect and elucidate the underlying mechanisms of VDAC1-ΔC on autophagy in renal tubular epithelial cells injured by hypoxia/reoxygenation.
Methods: C57/BL6 mice were randomly divided into groups: sham operation group, IRI 1d group and IRI 2d group. The inner canthal blood of mice was collected to detect the levels of serum creatinine and urea nitrogen and kidney tissues were sampled, and sections were stained with Periodic acid-Schiff for morphological evaluation.
