1, lower body resistance. Female friends if there are systemic diseases such as diabetes, but also easily lead to pyelonephritis.

2, bladder and urethra reflux. This refers to the urine when the urine from the bladder through the urethra to the renal pelvis of the abnormal, such as the bladder triangle and the lower end of the lower muscle tension and other factors, is easy to cause infection.

3, poor urine flow. A female friend of bradyuria will contribute to pathogen breeding caused ascending infection, such as polycystic kidney, kidney stones, renal tumor, renal ptosis, ureter or urethral stones and other diseases, and cancer, pregnancy, neurogenic bladder, prostate hypertrophy, need attention and treatment of patients with the disease.

4, the uplink infection is the most common route of infection of the urinary tract, when the body's resistance to decline in a slight damage to the urethra mucosa, bacteria easily invade the bladder and kidney infection. Because the female urethra than male female urethral short and wide, is often the fecal pollution, so it is easy to inflammation of pathogenic bacteria up to the first invasion of mucosa caused by pelvic kidney pyelonephritis, then the calyceal papilla tubular upward invade the renal parenchyma.

5, pyelonephritis is a direct invasion by a variety of pathogenic microorganisms, caused by renal pelvis renal mucosa and renal tubular interstitial inflammation. In recent years, it has been found that there are bacterial antigens in the renal scar tissue of some patients with pyelonephritis.

6, pyelonephritis etiology and blood infection, inflammation, bacteria from the body lesions invading the blood flow to the kidney to cause pyelonephritis, blood infection bacteria first arrived in renal cortex and the formation of the majority of small abscess in the area, and then along the tubular downward diffusion into the renal papilla and pelvis.

7 pregnant women, estrogen secretion Fen increased, ureter tension decreased, peristalsis is abate, cause urinary tract smooth, urinary tract reflux period of pregnancy is a higher probability of infection of urinary tract infection ([]: translation of pathogens in urinary tract in growth and reproduction, and invade the urinary tract mucosa or tissue caused by inflammation, bacterial infection is one of the most common infection. (mostly) pyelonephritis.

8, PI renal lesions, such as glomerulonephritis, renal cysts, renal tumors and chronic tubulointerstitial disease, can cause renal local antibiotic bacteria ability drops, with the incidence of pyelonephritis.
