Explore the clinical and pathophysiologic features of urinary tract malignancies through this 30-minute medical podcast episode that examines renal cell carcinoma and urothelial carcinoma of the bladder. Begin with a comprehensive patient case study of renal cell carcinoma, analyzing epidemiology and risk factors including smoking, obesity, hypertension, and inherited syndromes like von Hippel-Lindau disease. Understand the pathophysiology of clear cell RCC, focusing on VHL gene function loss and HIF pathway dysregulation that leads to increased angiogenesis. Learn to identify the classic triad of RCC symptoms—flank pain, hematuria, and palpable abdominal mass—alongside common paraneoplastic syndromes such as polycythemia and hypercalcemia. Master diagnostic evaluation techniques using CT imaging of the abdomen and pelvis, and discover treatment strategies ranging from partial or radical nephrectomy to immune checkpoint inhibitors and targeted therapies for advanced disease. Transition to examining urothelial carcinoma through another patient case, highlighting epidemiologic risks including tobacco use, occupational exposures, chronic inflammation, and cyclophosphamide exposure. Recognize clinical signs such as painless hematuria, irritative voiding symptoms, and hydronephrosis while learning the diagnostic approach through urine cytology, cystoscopy with biopsy, and CT urography. Study management strategies including TURBT, intravesical BCG, radical cystectomy, and systemic chemotherapy based on staging and risk assessment.
