Many men will find a little blood in their urine when they go to the toilet. At this time, men will feel panic, because after all, blood in urine is a kind of inflammatory disease, so it is easy for men to pay attention to it. They are especially afraid that there is something wrong with their prostate. So what is the cause of men's blood in urine? The following editor will give you a detailed introduction.

There are three types of hematuria: initial hematuria, terminal hematuria and complete hematuria. Initial hematuria means hematuria only occurs at the beginning of urination, and the lesions are mostly in the urethra. Terminal hematuria means hematuria occurs at the end of urination, and the lesions are mostly in the bladder trigone, bladder neck or posterior urethra. Complete hematuria means hematuria occurs throughout the entire process of urination, and the bleeding sites are mostly in the bladder, ureter or kidney.

Possible causes of hematuria are as follows: Urinary tract inflammation. If hematuria is accompanied by facial and body swelling, increased blood pressure and other symptoms, it may be acute nephritis; if hematuria is accompanied by difficulty urinating and pain in the urethra, it is mostly a symptom of prostatitis. Cystitis. If hematuria is accompanied by severe urinary frequency, urgency and pain, it is mostly acute cystitis. The most common symptom of cystitis is hematuria that can be seen with the naked eye without any feeling. Kidney or ureteral stones. If hematuria is accompanied by low back pain, sometimes severe paroxysmal low back pain and renal colic, it is likely to be kidney and ureteral stones. Urinary tract tumors. If hematuria is accompanied by prolonged frequent urination, urgency, and pain, it is more likely to be renal tuberculosis. If a person over 40 years old has pain and hematuria without obvious symptoms, it may be due to a urinary tract tumor.
