The smell of urine is not necessarily due to UTI, but may be related to lack of personal hygiene, so in this case there is no need to panic and patients should pay attention to cleanliness. However, if there is a urine odor and other symptoms, then the patient should go to a regular hospital in time. The diagnosis of UTI itself is not clear from the body odor, but should be concluded through several aspects of laboratory tests, and the urine should be examined. Urine tests include urine routine, which should be done by retaining at least 10ml of urine from the middle of the first morning urine for testing. Kidney function can also be tested by drawing blood, and at the very least, blood creatinine and urea nitrogen should be checked to observe whether the laboratory test results are normal. In addition, patients can also be examined by kidney imaging, such as the simplest kidney ultrasound. Therefore, patients can determine whether there are any kidney problems through a series of tests such as urine routine, kidney function, kidney ultrasound and imaging. Uremia, on the other hand, is the diagnosis of the end stage of chronic kidney disease, so the diagnosis of uremia cannot be confirmed simply by the body odor on the body.
