What is kidney infection? Kidney infection is usually secondary to lower urinary tract infection. Acute or chronic complications are easily caused by renal infection. So, what causes a kidney infection?

What is kidney infection?

General kidney infection secondary to lower urinary tract infection, because the blood supply of renal rich and flushing effect of urine, normal kidney has a strong resistance to infection, urinary tract infection and most asymptomatic bacteriuria do not develop urinary tract infection and kidney. Through the timely and effective antibiotic treatment, most of the mature kidneys of acute kidney infection can be better recovery, without scarring or damage to renal function. However, the presence of predisposing factors is more likely to lead to renal infection, and the treatment of renal infection is more difficult, and easily lead to acute or chronic complications.

What causes a kidney infection

What causes a kidney infection?

  • 1. bacteriuria: there is almost always bacteriuria in the active period of acute pyelonephritis infection.
  • 2. diabetes: the incidence of kidney infection in diabetic patients increases, and the treatment after infection is also relatively difficult. Sugar is an important nutrient for bacteria, and diabetes can increase the concentration of bacteria in urine. The immune function of diabetes patients decreased, and the killing effect of white blood cells on pathogenic bacteria was decreased. Because of the small vessel disease, the blood supply of the tissue is insufficient, which affects the inflammatory reaction and inhibits the infiltration of antibody into the inflammatory focus. Such as nerve damage, neurogenic bladder function abnormalities lead to bladder emptying abnormalities and urinary retention, is also prone to infection factors.
  • 3. urinary tract obstruction of urinary tract obstruction to urine stasis, bacteria easy hyperplasia. Increased renal pressure also causes local pathogens to develop.
  • 4. urinary calculi: whether or not combined with urinary tract obstruction, urinary calculi will create a good growth environment for pathogenic bacteria, so that drug-resistant strains grow.
  • 5. ureteral reflux: the incidence of renal infection is increased in patients with reflux of ureter and ureter.
  • 6. pregnancy: Although the bacterial content in urine of pregnant women before pregnancy is not significantly increased, but due to urinary obstruction and urinary system to pregnancy flow stasis will prone to infection.
  • 7. others: some factors that make kidney infection easy to happen and progress include analgesic drug nephropathy, uric acid nephropathy, immune system suppression and systemic debility.

The above is what is what causes a kidney infection, if you got a kidney infection, please timely treatment, lest the illness becomes heavier, if there are other problems to understand, please contact our online doctor.
