This word sounds terrible infection, when we are infected with some virus or other disease, our body will be much larger than in the past, the body's resistance and immunity will decline, there are a lot of kidney infection symptoms, such as frequent urination, these are stored in, because kidney infection will lead to changes in the urinary system we, the resulting other bad symptoms, then let us know about.

A urinary tract infection.

Urinary tract infection (urinary tract infection) is a large number of pathogenic microorganisms invade the urinary system growth, urinary tract inflammation caused by reproduction, generally refers to bacterial infection.

According to different parts of the lesions are often pided into:

The lower urinary tract infections: such as urethritis, prostatitis, cystitis.

The upper urinary tract infection, such as pelvic inflammation, pyelonephritis, renal abscess, renal abscess, renal inflammation. On the basis of onset urgent, and the pathological change rate pided into acute, chronic urinary tract infection; according to whether the clinical symptoms were pided into symptomatic urinary tract infection and asymptomatic bacteriuria; according to whether the functional or anatomical abnormalities into complicated and uncomplicated urinary tract infection; according to whether the initial onset is pided into primary and recurrent urinary tract infection, and then the hair can be pided into relapse and reinfection. Urinary tract infection is a common disease, according to statistics the incidence rate of China's population of 0.91%, of which the incidence rate of female is 2.37%.

Pathogens causing urinary tract infection with bacteria, fungi, viruses, mycoplasma, chlamydia and parasites. Gram negative enteric bacilli accounted for the majority, which accounts for about 80% of Escherichia coli, followed by Staphylococcus saprophyticus, few are Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and other gram negative bacilli and a few gram positive cocci.

1. routes of infection

(1) ascending infection: most urinary tract infections are caused by bacteria, namely by the urethral opening up to the bladder, ureter, renal pelvis caused by infection.

(2) blood infection: bacterial infection in vivo from the bloodstream to the kidney. For sepsis consequences.

(3) lymph infection: when pelvic organ inflammation, bacteria through the lymphatic infection of the kidney.

(4) direct infection of adjacent organs: kidney inflammatory fistula or infectious foreign body through kidney, causing infection.

2. decline in the body's defenses

(1) glycoprotein layer damage: glycosaminoglycan layer of bladder mucosa surface can inhibit the adhesion of bacteria, such as damage, easy to make bacteria and exposed epithelial binding.

(2) urinary secretory IgA decrease.

The above described renal infection symptoms in all aspects, in fact, it is not difficult to see that renal infection symptoms are more obvious, if patients in the early stage of the disease timely find their disease, and quickly into the treatment, so patients will quickly go up, does not affect their normal work and study, if found late, so, treatment of disease will become complicated.
