Overview

Acute renal failure always occurs in connection with some other medical condition or event. Being hospitalized with a serious condition requiring intensive care is the biggest risk factor. The risk factors for acute renal failure is divided into three major categories, namely pre-renal factors, renal factors and post-renal factors.

Risk Factors

Pre-renal Factors

Pre-renal risk factors are those that cause reduced blood supply to the renal nephrons. Most common risk factors are as follows:

Renal or Intrinsic Factors

These are risk factors that directly cause damage to the kidneys and cause renal failure. Common renal risk factors include:

Post-renal Factors

Post-renal risk factors are those that cause obstruction to the urinary outflow tract. Some common post-renal risk factors are as follows:

Other common causes
