I think I misspoke in class the other day. I’m not positive, but I may have used the term Oligouria incorrectly.
Regardless of what I may have said, I want to clarify here…
Oligiouria is the condition of producing small amounts of urine. Oligo- meaning ‘small, little’ + -uria, from the Gr. Ouron = urine. Clinically, oligouria is defined as the production of 100-400 ml of urine per day as opposed to the typical 400 to 2,000 mL — from about 2 liters of fluid intake.
Less than that and you’re in the realm of Anuria (a- meaning ‘no’ + -uria).
Decreased urine production can be caused by a number of conditions, but most commonly, it is an indicator of dehydration or hypovolemic shock, which may also sequelae of a variety of things. Hiking in the desert without water can do it, but so can kidney failure or a blockage – both of which can occur even with adequate hydration.
The other end of the spectrum is Polyuria, or the production of excessive urine ~more than 2.5 Liters over the course of a 24 hr day. This is essentially equivalent to Diuresis which is from the Gr. Diourein, meaning ‘to urinate’.

Nephrotoic Syndrome vs. Nephritic Syndrome
When looking for differences between these two Syndromes what I found most helpful was that Nephrotic was a loss of a lot of protein and Nephritic was a loss of a lot of blood and inflammation. I couldn’t find anywhere that it said that Nephritic Syndrome patients had polydipsia.
If you have Nephrotic Syndrome your medications will be: B/P meds, water pills, cholesterol-reducing meds, blood thinners, and immunesuppressants.
If you have Nephrotic Syndrome your medications will be: immunesuppressants, B/P decreasing meds, ACE/ARB medications can slow down progression
