Retrograde bacterial infections are those in which bacteria enter the urinary system from the urethra up through the urethra to the bladder and even into the kidneys or the parametrium or prostate. Most of the bacteria come from the intestinal tract, with E. coli being the most common. This is because the urethra is shorter in women (about 3-4 cm) and the opening is quite close to the vagina and anus, so bacteria can easily enter the urinary tract and cause infection due to poor hygiene or sexual behavior. Here’s how to effectively prevent retrograde bacterial infections. 1.Practice good living habits to avoid bacterial infections. 2.Find out the cause of the disease and go to the local hospital institution for treatment. 3.Bed rest, strengthen nutrition, and take appropriate amount of vitamins. 4.Maintain water, electrolytes and acid-base balance. Give blood, plasma, albumin and gammaglobulin transfusion if necessary. 5. Give physical cooling in case of high fever, sedation in case of irritability, etc. 6, pay attention to adjust the diet reasonable exercise to improve the resistance.
