Why does a woman’s urine test appear normal but she still has pain when urinating?

When we suspect that there is a problem with our urinary system, we can go to the hospital for relevant examinations. The simplest and most commonly used examination is the urine test. A routine urine test can effectively determine whether we have any disease. However, some women said that they had taken urine tests and the results showed normal, so why did they still feel very painful when urinating? Let's briefly analyze the reasons for this.

Causes of painful urination in women:

First of all, the female urethra and vagina are adjacent to each other, and bacteria can easily invade the vagina, especially after sexual intercourse. This is why "honeymoon cystitis" occurs.

Secondly, the female vagina is close to the intestines and anus, and many large intestinal bacteria can enter the vagina, causing urinary tract infection and leading to painful urination.

Third, although the surface of the female urinary tract is covered with a layer of mucus like a protective film, under normal circumstances, the vaginal mucosa will breed a kind of lactobacillus, making the vagina acidic and inhibiting bacterial invasion. However, when these natural defense functions are congenitally deficient or acquiredly changed, they can easily cause vaginal or urinary tract infections.

Diseases that may cause urinary pain:

1. Urethritis Urethritis directly affects urination. Its inflammatory bacteria can spread in the urethra and is one of the main factors causing urinary pain.

2. Endocervicitis

Endocervicitis in women causes congestion and edema of the cervix, easy bleeding when touched, increased yellow mucus and purulent secretions, and lower abdominal discomfort. These parts are closely related to the urethra and are all factors that cause urinary pain.

3. Nonspecific vaginitis

The main symptoms of nonspecific vaginitis are massive shedding of the vaginal epithelium, congestion of the vaginal mucosa, obvious tenderness, and in severe cases, general fatigue and lower abdominal discomfort. The discharge is excessive and purulent or serous. The outflow of discharge irritates the urethra and causes severe urinary pain.

4. Fungal vaginitis

The prominent symptoms of this disease are increased vaginal discharge and severe itching of the vulva and vagina, severe edema of the vaginal membrane, and the adhesion of white flaky films that are easy to peel off. In addition, the eroded base of the damaged mucosa or the formation of shallow ulcers can irritate the urethra and cause urinary pain.

5. Uterine fibroids are a common benign genital tumor in women aged 30 to 50. The symptom is a lump in the lower abdomen. Bacteria on these lumps may invade the urethra through the reproductive tract and cause painful urination.
