Anuria and Oliguria: Symptoms, Complaints, Signs

Anuria is a symptom of acute renal failure (ANV).

In the initial phase, ANV usually progresses without specific symptoms.

In manifest ANV, the following forms can be distinguished:

  • Oliguric course: <500 ml urine output/day.
  • Non-oliguric course: > 500 ml urine production/day.

In the polyuric phase, there is massive urine production. Other symptoms occur depending on the specific underlying disease.

If an acute outflow obstruction occurs, then it is an ischuria (urinary retention). Severe lower abdominal pain then usually occurs.
