Oliguria y Anuria

EmDocs - March 29, 2021 By Daniel A. Weidner and Michael J. Yoo
Reviewed by Alex Koyfman and Brit Long
“Take Home Points
  • Oliguria has a broad differential: rule out obstruction first.
  • Consider neurogenic causes of acute urinary retention such as cauda equina syndrome.
  • Search for and avoid nephrotoxins if possible: NSAIDs, ACEi/ARB, antibiotics, antivirals, diuretics, and drugs of abuse.
  • Prerenal etiologies are the most common cause of oliguria and are often caused by hypovolemia or infection; however, can’t miss causes include cardiorenal syndrome, hepatorenal syndrome, and abdominal compartment syndrome.
  • Relieve obstructions with a Foley catheter, and consider a Coude catheter in patients with large prostates and a three-way catheter in patients with bleeding and clots.”
