As a urologist, when we go out to the clinic, we often meet patients who come to the clinic with hematuria as the main manifestation. Some patients have red hematuria, flesh-like throughout, and blood clots, and even cannot urinate because of the blockage of hematuria and blood clots, and the patients are in great pain and the situation is very urgent. There are also some sudden back pain, followed by one hematuria, washing flesh water-like. And then the back pain disappeared, but still assured how this hematuria came. Some complain of hematuria for a while every now and then, a while dark red, a while all clear, sometimes without a little back pain and other performance, many patients do not take it seriously, and often say to the doctor that there is nothing serious, not the recent loss of weight also do not come to see it. There are also often to unit physical examination or repeated urine routine in the prompt microscopic hematuria, although not naked eye to see hematuria, but with the extension of time, patients and family members tangled very much, can not be assured, must find out. In some cases where hematuria cannot disappear in the short term after urological surgery, patients are not at ease and sometimes complain, thinking that it is caused by the surgery not being done properly, etc. All of the above indicates that there are many characteristics of hematuria, and sometimes the manifestations seen clinically often vary greatly depending on the disease and the individual. It is one of the most common diseases in clinical urology, and is one of the main symptoms of the first time thus visiting a urology clinic, and one of the main reasons why patients are easily urged to seek treatment as early as possible in a timely manner. Many patients think that hematuria is too terrible, easily causing blood loss, anemia and loss of nutrients in the body, which is very important and must be treated as soon as possible. Hematuria is really not something that you can take lightly and feel at ease about. Is hematuria really not reassuring? It is not easy to answer this question. How do urologists usually treat hematuria? There are many different manifestations of hematuria, and the causes of hematuria are also diverse, and can number in the hundreds. A urologist cannot hastily tell you a definitive diagnosis based on a simple questioning, routine ultrasound and routine urinalysis in a short time in an outpatient clinic. However, a urologist will tell you what kind of hematuria will be reassuring and what kind of hematuria should attract attention. Because of the multiple etiologies of hematuria, appropriate tests are usually taken clinically to diagnose and differentially diagnose the cause of hematuria by means of exclusion. First of all, if the cause of occult blood in urine is not clear in the short term, red blood cell morphology examination can be performed first to understand whether the hematuria is due to nephrological disease or urological disease. If the test results are homogeneous red blood cells in the urine, urological diseases are most often considered, and a specialized urological examination should be completed to assist in the diagnosis. Usually basic tests such as urological ultrasound and urinary routine are taken in the outpatient clinic, and the results of these tests will suggest a slight knowledge of the diagnosis. When patients with painless intermittent carnal hematuria undergo ultrasound, they will know the basic conditions of the kidney or bladder lesions, such as common pelvic ureteral tumors and bladder tumors, etc. CT examinations can further provide some understanding of the size of the lesion and the surrounding conditions; pyelogram can further understand the function of the kidney and the visualization of the upper urinary bladder. Cystoscopy is an invasive diagnostic tool that cannot be replaced by any of the imaging tests. It not only understands the site of hematuria such as the left and right side, but also further understands the specific situation in the bladder, which is significant for the development of the next treatment plan. At the end of the above related tests, you usually have a deep impression of the cause of hematuria basically and can basically understand the presence of urinary tumors, stones, tuberculosis, urinary tract infections, the presence of prostatic hyperplasia in male patients and many other causes. If none of the above, the presence of ruptured blood vessels of the kidney bladder bleeding, arteriovenous fistula, renal prolapse, nutcracker syndrome and other vascular aspects as well as congenital factors should also be considered. That is why some patients report spending tens of thousands of dollars on tests or not being sure of a diagnosis. Sometimes the cause of hematuria is often not a single one. The most unsettling thing for doctors is to miss the cause of hematuria, such as a combination of tumors and tuberculosis. In clinical practice, doctors often selectively and dynamically observe the progress of hematuria after they have been able to rule out the above-mentioned diseases, and take appropriate treatment measures according to the changes in hematuria. So which hematuria can be reassuring? When hematuria appears as soon as possible, especially consult with a physician who sees a urology specialist. With all of the above, hematuria is not reassuring at will. It is recommended to consult a regular hospital urology specialist as soon as possible when hematuria occurs.
