Objective: To evaluate the feasibility of kidney biopsy by transgastric and transvesical combined approach in the porcine model.
Methods: Five female pigs (20 to 30 kg) were included in this study. All procedures were performed with pigs under general anesthesia. The transvesical access was established by the ureteroscope. Then monitored by ureteroscopy, the transgastric access was established by a needle knife with cautery. The puncture dilation was performed with balloon through the gastroscope. The vesical hole was enlarged with the dilator of ureteroscope sheath. The kidney biopsy was finished by the scissor from the transvesical access and the grasping forcep from the work channel of gastroscope.
Results: Among five cases the procedure were successful in three cases with 380 min, 180 min, 78 min respectively. Establishment of transvesical and transgastric accesses took place without complications. The exposure and biopsy of the kidney were easily achieved during operation. The transgastric and transvesical access were not closed in the end.
Conclusions: This new method is a technically feasible procedure in a porcine model. But the safety and the clinical future of it needs more study.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer with a high metastatic rate and high mortality rate. The molecular mechanism of ccRCC development, however, needs further study. Aurora kinase B (AURKB) functions as an important oncogene in various tumors; therefore, in the present study, we aimed to explore the mechanism by which AURKB affects ccRCC development.

Viremia defined as detectable SARS-CoV-2 RNA in the blood is a potential marker of disease severity and prognosis in COVID-19 patients. Here, we determined the frequency of viremia in serum of two independent COVID-19 patient cohorts within the German National Pandemic Cohort Network (German: tionales andemie horten etzwerk, NAPKON) with diagnostic RT-PCR against SARS-CoV-2. A cross-sectional cohort with 1,122 COVID-19 patients (German: , SUEP) and 299 patients recruited in a high-resolution platform with patients at high risk to develop severe courses (German: , HAP) were tested for viremia.

Diabetes nephropathy (DN) is a severe diabetic chronic microvascular complication and the major cause of end-stage renal disease (ESRD). Our study aimed to investigate the effects of isoliquiritigenin (ISL) a natural flavonoid compound on DN and to explore the underlying mechanisms. The db/db mice were received intragastric treatments of ISL (5, 10, or 20 mg/kg), vehicle or positive drug metformin (300 mg/kg) once a day for 12 weeks, and the db/m mice treated with vehicle were used as controls.

Mixed epithelial and stromal tumor (MEST) of the kidney is a rare benign neoplasm composed of both stromal and epithelial components. MEST is mainly seen in adults with a strong predilection for perimenopausal women with history of hormone replacement therapy. While MEST is generally benign, there are reported cases of malignant transformation and adverse clinical outcomes.

Obesity is a rapidly growing health problem worldwide, affecting both adults and children and increasing the risk of chronic diseases such as type 2 diabetes, hypertension and cardiovascular disease (CVD). In addition, obesity is closely linked to chronic kidney disease (CKD) by either exacerbating diabetic complications or directly causing kidney damage. Obesity-related CKD is characterized by proteinuria, lipid accumulation, fibrosis and glomerulosclerosis, which can gradually impair kidney function.
