Why is the baby's urine blood

There are many causes of hematuria, including urinary tract infection, kidney stones, nephritis, etc. B-ultrasound and urine red blood cell morphology can be further performed to clarify the source of hematuria. If the proportion of abnormal red blood cell morphology exceeds 70%, glomerular hematuria can be diagnosed. If the proportion does not reach more than three types of abnormal red blood cell morphology, glomerular hematuria can also be diagnosed. So let's take a look at what is going on when babies urinate blood!

Hematuria in children is often seen in acute nephritis; hematuria in adolescents or middle-aged people should be considered for nonspecific bacterial infection of the urinary system, tuberculosis and stones; if hematuria occurs in women during the newly married or childbearing period, it is mostly due to inflammation of the renal pelvis, bladder and urethra. If hematuria is accompanied by bladder irritation symptoms such as frequent urination, urgency and pain when urinating, urinary tract infection should be considered; if accompanied by low back pain, percussion pain in the kidney area or fever, it is mostly pyelonephritis; if there are only bladder irritation symptoms and no systemic infection symptoms, it is mostly cystitis; if hematuria occurs after severe colic, it is mostly kidney or ureteral stones; pain during urination, sudden interruption of urine flow or difficulty in urination are mostly bladder or urethral stones; hematuria occurring after defecation or sexual intercourse is often posterior urethritis; hematuria occurring when standing but disappears when lying down, renal ptosis should be considered; hematuria occurring after strenuous exercise is post-exercise hematuria or kidney stones; if there is difficulty urinating for a long time first and then hematuria, prostate disease or urinary tract infection should be considered.

Among the countless causes of hematuria, we should be alert to painless hematuria, which refers to the sudden appearance of macroscopic hematuria without obvious inducement, but without pain and other manifestations. It is clinically called "painless macroscopic hematuria. Painless macroscopic hematuria is more common in elderly patients and is usually regarded as an important warning sign of urinary system tumors. It should be taken seriously. The elderly are a high-risk group for tumors. Common urinary system tumors include bladder cancer, kidney cancer, ureteral cancer, prostate cancer, etc.

Among them, bladder cancer is the most common, often manifested as gross hematuria throughout urination. Many patients have long-term hematuria symptoms, and some have hematuria 2-3 times a year. They think, "It doesn't hurt, it doesn't itch, just take some anti-inflammatory drugs and it will be fine." They don't pay much attention to it, and don't go to the hospital for examination. However, they don't go to the hospital for examination until the frequency of hematuria increases significantly. Often, it is late-stage urinary tract tumors, and many have lost the opportunity for surgery, which is very regrettable. Therefore, we remind everyone to pay attention to painless gross hematuria. Therefore, when people over 40 years old experience painless intermittent hematuria, they should first consider whether they have urinary tract tumors.
