What causes blood in the urine in women?

The phenomenon of hematuria in women is relatively common. There may be many reasons for hematuria in women, such as the existence of some renal pelvis, bladder and urethritis, ureteral stones, or kidney stones, which may cause hematuria.

1. If female hematuria occurs during the wedding or childbearing period, it is mostly caused by inflammation of the renal pelvis, bladder and urethra.

2. If hematuria is accompanied by bladder irritation symptoms such as frequent urination, urgency and pain during urination, 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 defecation or sexual intercourse, it is often posterior urethritis;

3. If hematuria occurs after severe colic, it is mostly kidney or ureteral stones; if there is pain during urination, sudden interruption of urine flow or difficulty in urination, it is mostly bladder or urethral stones;

4. If hematuria occurs when standing but disappears when lying down, renal ptosis should be considered;

5. If hematuria occurs after strenuous exercise, it may be post-exercise hematuria or kidney stones. If there is difficulty urinating for a long time followed by hematuria, prostate disease or urinary tract infection should be considered.

6. Painless hematuria is often a signal or manifestation of urinary tract malignancy.
