What are the infection routes of pyelonephritis?

? Many patients with pyelonephritis are very concerned about this topic. Pyelonephritis is a male disease. If you have pyelonephritis, you must go to a regular hospital as soon as possible to prevent the disease from getting worse. So what? Let's ask the experts from Shenyang 463 andrology hospital to give us a detailed introduction. Experts from Shenyang Men's Hospital said that pyelonephritis can be divided into acute pyelonephritis and chronic pyelonephritis, and the infection route of pyelonephritis is as follows: 1. Upward infection: the most common. Most pyelonephritis is caused by bacteria rising from urethra through bladder and ureter to kidney. Under normal circumstances, the body relies on defense mechanisms such as continuous flushing of urine, integrity of urethral mucosa and lysozyme in urine to resist the invasion of foreign bacteria. 2. Direct infection: refers to the inflammation of the tissues around the kidney, and then involves the kidney, with a low incidence. 3. Blood-borne infection: usually not common. When serious infection occurs in the body, pathogenic bacteria can reach the kidney through blood circulation, causing local inflammation. 4. Lymphatic infection: It means that pathogenic bacteria in the body invade the kidney through lymphatic circulation, which is also uncommon. ? I believe I can help you!
