The cause of hematuria can be analyzed by whether it is accompanied by other symptoms. Asymptomatic hematuria should first consider the possibility of urinary tract tumors. If hematuria is accompanied by pain, especially colic, urinary tract stones should be considered. If it is accompanied by urinary pain and interrupted urinary flow, bladder stones should be considered. If it is 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 judged based on the patient's medical history, age, color and degree of hematuria, etc.

Prevention of Urinary Tract Infections

1. General measures: ① Drink more water, preferably more than 2000 ml per day, and urinate every 2 to 3 hours. ② Patients who have sexual intercourse should urinate in time after sexual intercourse. If necessary, they should consult an obstetrician and gynecologist and choose an appropriate contraceptive method. ③Try to avoid the use of urinary tract instruments. ④ Cranberry juice. Experimental studies have shown that cranberry juice can prevent Escherichia coli from adhering to urothelial cells and help prevent urinary tract infections.

2. Antibiotic prevention: Antibiotic prevention can significantly reduce the chance of recurrence of urinary tract infection in women. For female patients with recurrent urinary tract infections two or more times within six months, or three or more times within one year, antibiotic treatment is recommended (Grade A). Prevention plans include continuous medication and post-coital medication, with a course of 6 to 12 months. These regimens must be used after the original urinary tract infection is cured (urine culture is negative 1 to 2 weeks after stopping the medication), and antibiotics can be selected based on previous drug sensitivity test results and the patient's drug allergy history. Compared with the continuous dosing method, the post-coital medication method is more convenient and more easily accepted by patients who have sexual intercourse. Cephalexin, ciprofloxacin, or nitrofurantoin can be taken within 2 hours after sexual intercourse.

3. Prevention in postmenopausal women: Local application of estrogen ointment in the vagina can restore the local environment of the vagina and reduce the chance of recurrence of urinary tract infection (Grade A).

4. For patients with frequent recurring urinary urges, their urinary system should be carefully examined for anatomical malformations, underlying lesions (such as stones, polycystic kidney disease, medullary sponge kidney, etc.) and overall immune system abnormalities.
