Silly question. Urine output per hour?

I can't remember what the normal urine output per hour is?

I keep thinking 33cc/hr? (If that's wrong, why am I thinking that???)

lol, thanks :nurse:

We were told in the beginning of our nursing program that 30mL/hr was the cut off for adequate, but that's in an otherwise healthy person. If you really want to make sure the kidneys are perfused properly, it's more like 1mL/kg/hr. So, for example, if a person weighs 80kg, in order to make sure their kidney perfusion/urinary output is adequate they need to be putting out at least 80mL/hr.

Interesting. My instructor told me 0.5mL/kg/hr. I love how there are so many ideas of what "normal" is out there.

In a way they're both right - 0.5ml/kg/hr is the minimum output indicating adequate renal perfusion and function, but >1ml/kg/hr indicates optimal hydration and adequate perfusion/function.

The former is often referred to a 30ml/hr, working on 60k (142lb) as an average weight. Obviously this means that patients who weigh more than this hypothetical average may be significantly dehydrated or hypoperfused is their output is only reported/treated when it drops below 30ml/hr.

Anonymous,

That is not a silly question! I'm glad you asked when you weren't sure ? A patient's urine output can be a very important "vital sign". I ask questions every day and continue to learn new things every day. Keep up the good work ?

0.5-1 cc/kg/hour

Now that's an encompassing answer I can get behind. Thanks!

Caution: 60 kg is approximately 132 lbs, not 142.
