What are the reasons for the infection of acute nephritis?2018-06-13 08:40
Because acute pyelonephritis is harmful, to avoid unnecessary injury caused by the disease, we need to actively grasp the cause of infection of acute pyelonephritis, and on this basis to find targeted treatment programs, then what is the cause of infection of acute pyelonephritis?The following aspects are the specific analysis given by the experts.
Infectious causes of acute pyelonephritis:
1, reduce the body's low resistance. If a female friend has a systemic disease, such as diabetes, it is also easy to cause pyelonephritis.
2, bladder - urethral reflux. This refers to the urination urine from the bladder through the urethral reflux to the anomalies of the renal pelvis, such as the lower triangular trigone and ureteral muscles under the influence of lower muscle tension is easily induced infection.
3, poor urinary flow. The poor urine flow of a female friend contributes to the propagation of the pathogen and causes the upper infection, such as polycystic kidney disease, kidney stones, kidney tumors, renal ptosis, ureteral or lower urinary tract stones and other diseases, as well as cancer, pregnancy, neurogenic bladder, prostatic hypertrophy , Requires more attention and treatment of patients with the disease.
4, the upward infection is the most common way of infection of pyelonephritis, when the body resistance decreased urethral mucosa slight damage, the bacteria are easy to invade the bladder and kidneys cause infection. Because the female urethra is much shorter and wider than the male, the female urethra is often contaminated by the feces, so the pathogenic bacteria up to the kidney first invades the pyelonephritis causing inflammation of the pyelonephritis, and then through the renal calyx renal tubule upstream invasion of the kidney substance.
5, pyelonephritis is a direct invasion by a variety of pathogenic microorganisms, caused by renal pelvis and renal calyceal mucosa and renal tubulointerstitial inflammation. In recent years, it has been found that some bacterial antigens exist in kidney scar tissue of some patients with pyelonephritis, indicating that the damage of immune renal tissue may also be one of the causes of inflammation in the pathogenesis of pyelonephritis.
6, the cause of pyelonephritis and blood infection, bacteria invade the blood flow from the body lesions to reach the kidney pyelonephritis caused by inflammation of blood infection bacteria first reach the renal cortex and the formation of the majority of small abscess there, and then along the tubular direction Descend to the renal papilla and renal pelvis.
7, pregnant women with urinary estrogen Fen increased, ureter tension decreased peristalsis is abate, cause urinary tract poor urinary reflux with higher probability of urinary tract infection during pregnancy is (urinary tract infection: refers to pathogens in the urinary tract growth and reproduction, and invade the urinary tract or tissue caused by inflammation, is a the most common infection of bacterial infections. ), most of the pyelonephritis.
