text: Yo, check it out, this study's aim was clear,
  To analyze renal function, problems we fear.
  Major vascular surgery, acute renal failure's threat,
  Gotta dive deep into these issues, no room to forget.
  
  First, let's break down the factors causing renal damage,
  In this surgical branch, yo, it's a savage rampage.
  Then we discuss the physiological changes, you see,
  Renal injury's characteristics, that's the key.
  
  We talk techniques used to detect and monitor,
  Keep a close eye on those kidneys, we explore.
  And when it comes to therapy, we got tools in our stash,
  Preventing acute renal failure, that's the ultimate task.
  
  Now, let me share my personal experience, listen up,
  Nifedipine and low-dose dopamine, a winning combo, what's up?
  During abdominal aortic surgery, they came to play,
  Significant data, showing the impact, okay?
  
  To conclude, acute renal failure's caused by ischemic attack,
  In major vascular surgery, that's the painful fact.
  Prevention's the game, treatment falls behind,
  Managing cardiovascular function, that's the find.
  
  Invasive hemodynamic monitoring is the real deal,
  Protecting the kidneys, that's how we heal.
  Pharmacological protection, diuretics and dopamine,
  They play a role, but hemodynamics reign supreme.
  
  And calcium antagonists, they might be the key,
  Guarding the kidneys against an ischemic spree.
  So remember, in major vascular surgery's dance,
  We gotta protect those kidneys, give 'em a chance.
