Small Blisters at the Urethral Opening: Causes and Treatments

Urethral meatus small blister?

Hello Doctor: About four days ago, after having sexual intercourse, I noticed many small red spots on the glans.
They are not painful or itchy.
Later, I went to a urologist for an examination, and he said it was glans inflammation and that I shouldn't worry.
He prescribed me the following medications and ointment: DEXAZONE 0.5 gm (oral), VITAMIN B COMPLEX (oral), DELAMINE 2 gm (oral), KMT (oral), and CLOBETASOL 5 gm (topical).
After two days of using the medication, my red spots disappeared, and there were no other secretions.
However, I noticed two or three small blisters at the opening of the urethra, resembling tiny burns (white and very small), only at the urethral opening and nowhere else.
What should I do? Is this a sexually transmitted infection? I went to see the doctor again, and he just said to continue applying the medication and not to worry, without conducting any further tests.
I hope you can help me.

Itching of the penis and small red rashes on the glans may be early signs of some skin inflammation, or it could be genital herpes.
In young males, balanitis (inflammation of the glans) is often related to sexual activity, so it is important to rule out sexually transmitted infections (STIs).
Not all STIs can be confirmed through testing; clinical evaluation through visual inspection and palpation is often necessary to determine the possible causes of skin changes.
Other causes may be related to hygiene practices, dermatitis, or allergic skin conditions.
However, the condition can vary significantly among different patients, and it is important to note that a simple description cannot determine the diagnosis.
Physicians typically require a thorough medical history, visual examination, palpation, and tests to establish a diagnosis and treatment plan.
Since you have already sought medical attention, please consult your physician if there are any changes.
Additionally, it is advisable to have a stable sexual partner and to consistently use condoms to reduce the risk of STI transmission; prevention is better than treatment.

More Info

The appearance of small blisters at the urethral opening, especially following a recent sexual encounter, can understandably cause concern. Based on the information provided, it seems that you have already consulted a urologist who diagnosed you with glans inflammation and prescribed a treatment regimen. The fact that the red rash on the glans has resolved is a positive sign, indicating that the initial inflammation may have been effectively managed.

However, the development of small blisters at the urethral opening warrants further attention. Here are some potential causes and considerations regarding your symptoms:
1. Irritation or Allergic Reaction: The blisters could be a result of irritation from soaps, lotions, or even from friction during sexual activity. Allergic reactions to latex condoms or lubricants can also manifest as localized skin changes.

2. Infection: While the initial diagnosis was glans inflammation, the presence of blisters could suggest a viral infection, such as herpes simplex virus (HSV), or a bacterial infection. Herpes can present as small, painful blisters, but it can also be asymptomatic in some cases. Other sexually transmitted infections (STIs) could also cause similar symptoms.

3. Pearly Penile Papules: These are small, harmless bumps that can appear around the glans and are often mistaken for lesions. They are normal anatomical variations and do not require treatment.

4. Folliculitis: This is an inflammation of the hair follicles that can occur in the genital area, leading to small, red, pus-filled bumps.

Given that your urologist has advised you to continue the prescribed treatment and not to worry, it is essential to monitor the situation closely. If the blisters do not resolve or if you experience additional symptoms such as pain, itching, or discharge, it would be prudent to seek a follow-up appointment.
In terms of treatment, the medications you have been prescribed, including dexamethasone (DEXAZONE), vitamin B complex, and clobetasol, are aimed at reducing inflammation and promoting healing. Clobetasol is a potent topical steroid that can help with inflammatory skin conditions.
If the blisters persist or worsen, further diagnostic tests may be warranted, such as a swab for culture or PCR testing to rule out viral infections like HSV.
In summary, while the initial diagnosis and treatment seem appropriate, the appearance of new symptoms should not be ignored. Continuous monitoring and open communication with your healthcare provider are crucial. If you have any doubts or concerns, seeking a second opinion from another urologist or dermatologist specializing in genital conditions may provide additional reassurance and clarity.
