What causes bleeding in urine after sex?

The cause of hematuria can be analyzed by whether it is accompanied by other symptoms. The possibility of urinary tract tumors should be considered first for hematuria without symptoms. If hematuria is accompanied by pain, especially severe pain, urethral stones should be considered. If accompanied by urinary pain and interrupted urine stream, bladder stones should be considered. If accompanied by obvious bladder irritation symptoms, urinary tract infection, urinary tract tuberculosis and bladder tumors are more common. In addition, the cause of hematuria should be comprehensively identified in combination with the patient's medical history, age, color and level of hematuria.

Prevention of urinary tract infection

1. General measures: drink more water to lower blood pressure, the daily intake should be above 2000ml, and urinate every 2-3 hours. Patients with high blood pressure should urinate immediately after sex, and should consult an obstetrician and gynecologist if necessary and choose a suitable contraceptive method. Add and minimize the use of urethral devices. Drink cranberry juice, experimental research shows that cranberry juice can prevent Escherichia coli from adhering to the squamous epithelial cells of the urethra, which can help prevent urinary tract infections.

2. Antibiotic prevention: Antibiotic prevention can significantly reduce the chance of urinary tract infection in women. For female patients who have urinary tract infection 2 or more times within 6 months, or 3 or more times within 1 year, antibiotic treatment (A grade) is strongly recommended. The prevention plan includes continuous medication and post-sexual medication, and the treatment course is 6 to 12 months. This plan must be used after the original urinary tract infection is cured (urine culture is negative after 1 to 2 weeks of discontinuation of medication), and antibiotics can be selected based on past drug sensitivity test results and the patient's drug hypersensitivity. Compared with the continuous medication method, the medication method after sex is more convenient and more acceptable to patients who have sex. Cefuroxime, ciprofloxacin or nitrofurantoin can be taken within 2 hours of sexual intercourse.

3. Prevention for postmenopausal female patients: Applying estrogen ointment into the vagina can repair the natural environment inside the vagina and reduce the chance of urinary tract infection (Grade A).

4. For patients with frequent recurrent urinary complaints, their urogenital system should be carefully examined for anatomical malformations, basic diseases (such as stones, polycystic kidney disease, medullary spongiosophagus, etc.) and overall abnormalities of the human immune system.
