Efficacy of Everolimus for Treating Renal Angiomyolipoma with Inferior Vena Cava Thrombus Associated with Tuberous Sclerosis: A Case Report

Here we report a case of 57-year-old woman with renal angiomyolipoma associated with tuberous sclerosis complex involving inferior vena cava thrombus. We could perform less invasive nephrectomy with thrombectomy because everolimus administration reduced the inferior vena cava thrombus. To the best of our knowledge, this is the first report the use of everolimus before performing surgery to treat renal angiomyolipoma with inferior vena cava thrombus

Avelumab plus axitinib for translocation renal cell carcinoma: A case series and literature review

Introduction Patients with translocation renal cell carcinoma (tRCC) have a poor prognosis without standardized treatment. Case presentation The first case was of a 72‐year‐old woman who underwent robot‐assisted partial nephrectomy for a left renal tumor and was pathologically diagnosed with tRCC. Recurrence was observed in the left retroperitoneal soft tissue. After treatment with avelumab–axitinib, continued progression‐free survival was confirmed at the 90‐week follow‐up. The second case was of a 41‐year‐old woman referred to our hospital and presented with translocation renal cell carcinoma metastasis to a para‐aortic lymph node. After treatment with avelumab–axitinib, continued progression‐free survival was confirmed at the 43‐week follow‐up. Conclusion The outcomes of these cases indicate that avelumab–axitinib therapy has a long‐term antitumor effect in some patients with tRCC

Parenchymal renal rupture due to an obstructive ureteric calculus in an incompletely duplicated renal pelvis and ureter

Introduction Parenchymal renal rupture due to a ureteric calculus is extremely rare and an emergency. Case presentation A 54‐year‐old man was brought to the emergency room with left back pain without trauma. Computed tomography showed left parenchymal renal rupture with an incompletely duplicated renal pelvis, ureter, and an 11‐mm ureteric calculus in the ureterovesical junction. A ureteral stent was placed, and the patient was treated conservatively as his vital signs were stable. We performed transurethral lithotripsy after resolution of the perirenal hematoma. Conclusion To best of our knowledge, this report is the first to present a case of parenchymal renal rupture due to a ureteric calculus in an incompletely duplicated renal pelvis and ureter. Ureteric calculus within an incompletely duplicated renal pelvis and ureter is at risk of parenchymal renal rupture. Therefore, the aggressive treatment of ureteric calculus could be important
