Urinary Tract Infection There are several ways?

Generally believed that the way to a urinary tract infection uplink infections, blood infections, lymphatic infections and direct infection in four ways. (1) Upstream infections: the vast majority of urine flu is caused by infection of the uplink. Under normal circumstances, and around the urethra is a parasitic bacteria, but do not normally cause infection. When the body resistance decreased urethral mucosa or minor injury, or bacterial virulence, adhesion urethral mucosa and the uplink, and a strong ability easy invasion bladder and kidney, causing infection. The female urethra and around the anus, and the female urethra is shorter than men and width, whose urethra often faecal contamination, the more pathogenic. (2) blood infections: bacteria from the body's Ganranzao (such as tonsillitis, sinusitis, dental caries or skin infections, etc.) invade the bloodstream, kidney arrived first in the renal cortex of multiple small abscess caused, and then along the tubular downward and spread to the renal papillary renal calyceal, pelvis mucosa, but also from inflammation of the renal papilla minor injury nipple collecting duct (such as the crystallization of injury in urine), and then down the spread upward. Blood infection means more rare, less than 10 per cent. Comparison of blood was particularly prevalent in the neonatal infection, or sepsis patients with Staphylococcus aureus the blood of kidney infection. (3) lymphatic infections: lower abdomen and pelvic lymphatic organs and renal peripheral lymphoid possession of the majority of traffic branch, or between the right kidney and colon also lymphatic communication. When pelvic organ inflammation, appendicitis and colitis, the bacteria are available from lymphatic kidney infection. This means more rare infection, or even the existence of this infection means, and there is also controversy. (4) Direct infections: trauma or adjacent organs kidney infection, invasive bacteria can be directly caused kidney infection, but this clinical situation is extremely rare.
