A 48 year-old male presents to your clinic complaining of: “I am gaining weight very fast and I am not eating at all and another thing, my urine, I am not ‘peeing’ as much as before.” Past medical history is
significant for hypertension and diabetes type I. Physical exam was significant for elevated blood pressure. Laboratory work-up confirms your diagnosis. The patient was given a diagnosis of chronic renal
failure secondary to poorly controlled hypertension and diabetes. His anti-hypertensive and diabetic medications were altered to ensure compliance and efficacy. The first step in urine formation occurs
