Renal Sinus Infection: What You Need to Know

Renal sinus infection, or commonly known as kidney or upper urinary tract infection, can cause serious medical problems when not addressed immediately. It might even lead to renal sinus cyst that can cause life-threatening conditions and serious health reverses.

Our kidneys are a vital organ that needs to be taken cared of since these remove toxic materials in the body such as urine, and help in balancing electrolytes, minerals, salt and water. When the function of the kidneys are hampered by infection and stop getting rid of waste products then our bodily functions are in trouble as well. There will be electrolyte and fluid build-up in the body which might prove very hazardous to one’s health.

The renal sinus serves as the location for most nerves and calyxes that are responsible for waste disposal of the kidney. Below is a more thorough discussion of the renal sinus.

What is renal sinus? It is simply a cavity in the kidney that serves as the expansion behind the renal calyxes, renal pelvis, nerves, blood vessels and fat.

Cause of Renal Sinus Infection

It can be caused by poor nutrition, bacterial infection in the urine from the anus, skin and vagina. Unhygienic practices during sexual intercourse can also cause this type of infection.

Pregnant women are also exposed to higher risk of this type of infection since the urethra is shorter, their urethras pressured due to the enlarged uterus and frequent urination opens them to bacterial infection. Structural abnormalities in the kidney may also cause this problem.

Catheters can also cause infection since it provides the “passage” for the bacteria to get inside the kidney. Kidney stones are also culprits when it comes to causing infections that can affect the renal sinus of the kidney. Since these causes obstruction in the passage of urine, bacteria build up is not impossible thus increasing the chances of renal sinus infection.


Renal sinus infection or upper Urinary tract infections are more prevalent in women that are 50years old and below. It is also common in children especially for girls 4 years and below. The said infection is rare in men and usually affects 10% of men and 40% of women in their lifetime.

Common Bacteria that Causes Renal Sinus Infection

Most of kidney infections are caused by bacteria that attack the urinary system. The most popular is E. coli or Escherichia coli that is responsible for 80% of kidney infection cases. Others may be caused by:

  • Staphylococcus Saprophyticus
  • Pseudomonas,
  • Proteus,
  • Klebsiella,
  • Enterococcus,
