Introduction
Possible causes of redness and swelling of the urethral opening include environmental factors, post-coital reactions, changes during menstruation, urinary tract infections, and balanitis. To prevent such issues, maintain a well-ventilated and dry living environment, practice good personal hygiene, frequently change and wash underwear made of breathable materials, clean the genital area after sexual activity, and use mild, breathable sanitary products during menstruation.

Under normal circumstances, redness and swelling of the urethral opening may be caused by environmental factors, post-sexual activity reactions, changes during menstruation, urinary tract infections, or balanitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified healthcare provider. Specific causes are analyzed as follows:

1. Environmental Factors

Long-term exposure to hot and humid environments, combined with poor personal hygiene, can accelerate the growth of bacteria and viruses, which may irritate the urethral opening and lead to redness and swelling. It is important to maintain a well-ventilated and dry living environment, frequently change and wash underwear, and wear properly fitting, breathable undergarments.

2. Post-Sexual Activity Reaction

During sexual activity, tissues around the urethral opening may experience minor trauma due to friction, leading to localized inflammatory response and resulting in redness and swelling. This type of swelling usually resolves on its own within a short period. It is advisable to maintain good personal hygiene, clean the external genital area with warm water, and avoid using harsh or irritating cleansers.

3. Changes During Menstruation

In women, hormonal fluctuations during menstruation, along with the use of sanitary products such as pads, may contribute to redness and swelling of the urethral opening. It is recommended to choose sanitary pads that are breathable and made of gentle materials to prevent allergic reactions and irritation. Change sanitary pads frequently and keep the external genital area clean and dry.

4. Urinary Tract Infection (UTI)

A urinary tract infection occurs when microorganisms such as bacteria or viruses invade the urethra, causing inflammation of the urethral mucosa and resulting in redness and swelling of the urethral opening. Common symptoms include frequent urination, urgency, and painful urination. Treatment should follow medical advice and may include medications such as indomethacin suppositories, diclofenac sodium sustained-release tablets, or ceftriaxone sodium for injection.

5. Balanitis

Balanitis is an inflammation specific to males, commonly caused by long foreskin, phimosis, or poor personal hygiene leading to bacterial overgrowth. In severe cases, the inflammation may spread to the urethral opening, causing redness, swelling, and pain. Symptoms may also include red patches and erosion on the glans penis. Treatment under medical supervision may include topical or oral medications such as clotrimazole cream, erythromycin ointment, or fluconazole capsules.

To prevent redness and swelling of the urethral opening, it is important to maintain a dry and well-ventilated living environment, practice good personal hygiene, frequently change and wash underwear made of breathable materials, clean the genital area after sexual activity, and use gentle, breathable sanitary products during menstruation.
