Acute Renal Failure: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate acute renal failure (ANV):

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

Three parameters provide initial clues to impending renal failure:

1. Increased heart rate (if heart rate had increased by ten beats at a time; OR: 1.12).
2. Cold extremities (arms and legs; OR: 1.52).
3. Prolonged capillary revascularization time over the sternum (OR: 1.89)

In manifest ANV, the following forms can be distinguished:

• Oliguric course – < 500 ml urine production/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.
