summary

Before, I didn't know much about pyelonephritis. I only knew it was a kind of disease. But recently, I have gained some basic knowledge about this kind of disease, because my family has relatives suffering from this kind of disease. Let's talk about the symptoms of pyelonephritis.

What is the symptom of pyelonephritis

First: pyelonephritis is a common disease of urinary tract infection. Inflammation of renal pelvis, calyces and parenchyma directly caused by pathogenic bacteria infection. Urinary tract infection includes upper urinary tract infection (pyelonephritis) and lower urinary tract infection (urethritis, cystitis), the latter can exist alone, and pyelonephritis is generally accompanied by lower urinary tract infection.

Second: pyelonephritis is divided into two types: acute pyelonephritis and chronic pyelonephritis. The former is mainly characterized by fever, frequent micturition, urgency of micturition, urination pain and low back pain. Routine urination examination can detect white blood cells (pus cells) and bacteria. The latter symptom is lighter generally, can come from acute pyelonephritis protracted; or although acute pyelonephritis gets control, but come through repeated attack evolution.

Third: in normal people, there are a small amount of bacteria at 1-2 cm inside the urethral orifice, but it generally does not cause infection, because the urethral mucosa has a certain antibacterial ability; the urine can dilute the bacteria and discharge them out of the body; the urine also contains some antibacterial substances. When the body's resistance decreases or urethral mucosa is slightly damaged (such as menstruation, after sex, etc.) and urinary tract circulation is not smooth, bacteria take advantage of the situation.
