Why does it hurt for women to urinate after having sex?

Pain during urination in women after intercourse may be related to urethral irritation, urinary tract infection, vaginitis and other factors. Common causes include urethral mucosal damage caused by intercourse friction, urinary tract infection caused by bacterial invasion, and vaginal secretions irritating the urethra. If symptoms persist or worsen, it is recommended to seek medical treatment promptly to investigate the specific cause.

1. Urethral mucosal injury

Mechanical friction during intercourse may cause minor damage to the urethral opening or surrounding mucosa, manifesting as a burning sensation or stinging during urination. There is usually no abnormal discharge in this case, and it will resolve on its own after 1-2 days of rest. It is recommended to clean the perineum before and after intercourse, avoid excessive violent movements, and rinse with warm water after urination to relieve discomfort.

2. Urinary tract infection

Retrograde infection of bacteria through the urethra may cause cystitis or urethritis, often accompanied by frequent urination and urgency. Escherichia coli is the most common pathogenic bacteria, which may be related to bacterial translocation during intercourse. Routine urine examination is required to confirm the diagnosis. For treatment, antibiotics such as levofloxacin hydrochloride tablets and cefixime dispersible tablets can be used as directed by the doctor. At the same time, you need to drink more water to promote the elimination of bacteria.

3. Secondary irritation from vaginitis

Abnormal secretions produced by trichomonas vaginitis or bacterial vaginosis may irritate the urethral opening and cause pain during urination. Such patients are often accompanied by vaginal itching, odor and other symptoms. The pathogen needs to be identified through routine examination of leucorrhea, and drugs such as metronidazole vaginal effervescent tablets and clotrimazole vaginal tablets can be used to treat the primary disease.

4. Allergic reaction

If you are allergic to condoms, lubricants and other products, it may cause redness, swelling and stinging in the urethral orifice. It is usually accompanied by skin pimples or itching, and symptoms gradually subside after cessation of exposure to the allergen. If necessary, oral loratadine tablets can be taken to treat allergies. It is recommended to change hypoallergenic products and avoid using sanitary products containing fragrance ingredients.

5. Urinary system stones

Small stones in the bladder or urethra move when the sexual position changes, which may scratch the urinary tract mucosa and cause pain. This type of pain is often knife-like and may be accompanied by hematuria. Diagnosis needs to be confirmed by urinary tract ultrasound. Smaller stones can be treated with Paishi granules and plenty of drinking water. Larger stones require extracorporeal shock wave lithotripsy.

On a daily basis, you should pay attention to urinating in time to flush the urethra before and after having sex, choose cotton breathable underwear and change it every day. Avoid over-cleaning the perineum, which may disrupt the balance of bacterial flora. It is recommended to use warm water instead of lotion when cleaning. If pain on urination occurs repeatedly or is accompanied by fever, hematuria and other symptoms, you need to go to a urology department or gynecology department as soon as possible to complete a clear diagnosis such as urine culture and vaginal microecological testing. Sexual intercourse should be prohibited during treatment, and medication should be prescribed according to the treatment course to prevent recurrence.
