Why does a child's genitals hurt after urination?

In general, genital pain in children after urination may be caused by factors such as urine irritation, physiological development, urethral trauma, urethral stones, or balanoposthitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Urine Irritation

During urination, a child's urine contains acidic substances that may irritate the skin or mucous membranes around the urethral opening as the urine passes through the urethra, causing discomfort or pain in the genital area. It is recommended to ensure the child drinks sufficient water to reduce irritating components in the urine.

2. Physiological Development

During growth and development, the skin and tissues in the genital area undergo stretching and adjustment, which may lead to feelings of genital pain. Usually, no special treatment is required. Maintaining cleanliness of the genital area and preventing infection are advised.

3. Urethral Trauma

Trauma can cause rupture or injury to the urethral mucosa, resulting in genital pain. Depending on the severity of the injury, appropriate treatments such as hemostasis, suturing, or anti-infective therapy should be selected.

4. Balanoposthitis

Balanoposthitis may be associated with bacterial or fungal infections, phimosis, or other factors. Inflammation causes pain in the foreskin, and contact with urine during urination may exacerbate the pain. Symptoms may also include redness, swelling, and itching of the foreskin. Under medical supervision, patients may use medications such as erythromycin ointment, clotrimazole cream, or azithromycin granules to relieve symptoms.

5. Urethral Stones

Urethral stones may result from factors such as urethral stricture or infection. When stones move within the urethra, they may scratch the urethral mucosa, causing genital pain. Symptoms may also include interrupted urine flow and hematuria. Patients should visit a reputable hospital for surgical treatment, such as ureteroscopic lithotripsy.

Choose breathable, comfortable underwear and change them regularly to keep the genital area dry. During episodes of genital pain, avoid strenuous physical activity to prevent worsening pain or additional injury.
