What is the treatment for post-renal renal failure?

• A. Appropriate urinary drainage (IV fluids and foley)
• B. High-dose IV antibiotics
• C. Immediate nephrectomy
• D. Administer diuretics only

Answer: (A)

Post-renal failure happens when urine flow is blocked downstream of the kidneys, causing pressure build-up that reduces filtration. The most effective treatment is to relieve that obstruction and restore drainage. Placing a urinary catheter to drain the bladder, along with IV fluids if the patient’s volume status requires it, directly addresses the blockage and can allow renal function to recover quickly if the obstruction is relieved promptly. Antibiotics are not the first step unless infection is present, and removing a kidney (nephrectomy) is not the initial or typical approach for an obstruction. Diuretics alone do not fix the blockage and can worsen fluid and electrolyte balance.
