What’s The Difference between Kidney Infection vs Kidney Failure?


y Failure vs Kidney infectionKidney infection, medically known as Pyelonephritis, happens when bacteria make their way and proliferate inside your urinary tract. It can happen due to improper hygiene practices, the presence of renal stones and even frequent and prolonged bladder catheterization. Pregnancy and diabetes can also predispose a person to such infection.

Renal failure, on the other hand, happens when your organs have stopped functioning. Because they can no longer get the job done, you’ll have to undergo dialysis or wait for a possible match for organ transplant to avoid debilitating complications. Heart attack, drug abuse and trauma to the renal tract can cause failure.

Signs of Kidney Infection

  • Changes in urinary pattern and characteristics, including color, smell and frequency are very common in patients with this condition. Pain upon urination is also an indication of possible kidney infection.
  • There’s the presence of dull pain on the lower part of the back which typically radiates to the side and stomach.
  • Fever and chills can also appear in cases of severe infection.
  • Patients frequently complain about nausea and vomiting which can lead to poor appetite.
  • There’s a notable weakness and fatigue as well.


Signs of Renal Failure

  • Because of too much fluid in the body, patients are likely to experience shortness of breath.
  • Swelling of the legs and feet can also happen. If the swelling is severe, it can also affect the patient’s hands and even his face.
  • Patients also find it difficult to sleep which can affect their energy level throughout the day when in kidney failure.
  • Because the electrolyte levels inside the body are also affected, manifestations like muscle cramps can happen.
  • Since toxins accumulate inside the body, itching of the skin can develop. You’ll often see patients with renal failure having dry and flaky skin that can sometimes turn into rashes.
  • The presence of abdominal and back pain is also common.
  • Patients with renal failure can either pass too much or too little amount of urine, depending on the stage of his condition.
  • Metallic taste in the mouth can also develop. It alters the patient’s sense of taste and, as a result, he loses appetite and weight.


Because the signs and symptoms of renal infection and failure overlap, it’s relatively easy to mistake one from the other. This, in fact, is one of the most common reasons why a simple infection turns into failure over time.

If you happen to notice any of the following signs, make it a point to seek medical help right away. There are a lot of diagnostic procedures and laboratory assessments that can help properly differentiate the two conditions. Good prognosis can be expected in kidney patients if there’s prompt treatment.
