The regular passage of urine helps to flush pathogens out of the urinary tract. When bacteria make their way into your urinary tract and begin to multiply, UTIs occur. This can lead to symptoms. These bacteria have often come from your gastrointestinal tract and spread from your anus into your urinary tract.
Women are more likely to develop UTIs than men. This is because the female urethra is shorter than the male urethra and closer to the anus. Bacteria have a shorter distance to travel in order to establish an infection. However, sexually transmitted infections STIs such as chlamydia and gonorrhea can also cause urethritis. If left untreated, UTIs can continue to spread upward into your kidneys. A kidney infection can lead to serious complications, including kidney damage or a life threatening condition called sepsis.
Although most kidney infections occur because another UTI has spread into a kidney, there are other possible causes. A kidney infection can also occur when a kidney stone blocks the urinary tract, which traps bacteria and leads to infection. This can quickly become very serious and requires immediate medical attention, which may include a urological procedure to remove or break up the stone.
First, the doctor will ask you about your symptoms. This information will help them differentiate between a simple UTI and a kidney infection. The doctor will diagnose a UTI by analyzing a urine sample. They can test the urine sample for the presence of substances such as bacteria, blood, or pus. Additionally, bacteria may be cultured from a urine sample. If a kidney infection is not treated, it can get worse and sometimes cause permanent kidney damage.
