How does adhesion at the urethral meatus occur after circumcision?

Introduction
Postoperative urethrocutaneous adhesion after circumcision is caused by factors such as urine residue and secretions, congenital urethral developmental abnormalities, surgical trauma, postoperative scar tissue formation, and wound infection. Some patients may have abnormal ureral meatus position or urethral stricture, which increases the risk of postoperative adhesion. Depending on the specific situation, urethroplasty may be required to reconstruct the normal urethral structure.

Generally, urethral adhesion after circumcision is caused by residual urine and secretions, congenital urethral developmental abnormalities, surgical trauma, postoperative scar tissue formation, or wound infection. If discomfort occurs, seek medical attention promptly. Detailed explanations are as follows:

1. Residual Urine and Secretions

After surgery, residual urine, wound exudate, or skin secretions may accumulate near the urethral opening. If not cleaned promptly, these substances may cause adhesion. It is important to maintain local hygiene, change underwear regularly, and clean the wound as instructed.

2. Congenital Urethral Developmental Abnormalities

Some patients may have abnormal positioning of the urethral opening or urethral stricture, which increases the risk of postoperative adhesion. Depending on the specific condition, urethroplasty may be required to reconstruct the normal urethral structure.

3. Surgical Trauma

Circumcision itself causes some degree of trauma to surrounding tissues, which may lead to adhesion around the urethral opening. During surgery, procedures such as cutting and suturing may damage the mucosa and skin near the urethral opening, resulting in adhesion. Urethral adhesion caused by surgical trauma can generally be prevented by maintaining local hygiene and avoiding infection.

4. Postoperative Scar Tissue Formation

During wound healing, excessive activation of fibroblasts may lead to overproduction of collagen and the formation of scar tissue. If this occurs near the urethral opening, it may cause adhesion, possibly accompanied by symptoms such as discomfort during urination or a narrowed urine stream. It is recommended to use medications such as heparin sodium ointment, vitamin E capsules, or asiaticoside tablets as directed by a physician.

5. Surgical Wound Infection

After circumcision, improper wound care or poor personal hygiene may lead to bacterial infection, causing inflammation of tissues around the urethral opening and subsequent adhesion, which may present with symptoms such as redness, swelling, and pain. It is necessary to use antibiotics such as amoxicillin capsules, penicillin V potassium tablets, or azithromycin dispersible tablets as directed by a physician.

Wear loose-fitting underwear to avoid pressure on the surgical site, which may interfere with postoperative recovery.

Is premature ejaculation related to phimosis?
Premature ejaculation is associated with phimosis to some extent, but there is no direct cause-and-effect relationship. Phimosis may be one of the contributing factors for premature ejaculation, but it is not a determining factor. If phimosis is present along with premature ejaculation, it is recommended to seek medical evaluation to identify the specific cause of premature ejaculation before deciding whether circumcision or other targeted treatments are needed. Avoid attributing the condition solely to phimosis or attempting self-treatment.

What causes bleeding from the frenulum of the foreskin, and what should be done?
Bleeding from the frenulum of the prepuce may be caused by excessive sexual activity, frenulum tear, frenulum inflammation, frenulum cyst, or penile ulceration. Immediate hemostasis and wound cleaning are necessary. Depending on the severity of the injury, management options may include sterile gauze dressing, application of cold or warm compresses, oral antibiotics, or topical ointments. If necessary, seek prompt medical attention for wound suturing or surgical treatment.

What should be done about adhesion between the foreskin and the glans?
In general, adhesions between the foreskin and the glans penis can be managed through methods such as proper hygiene, manual separation, topical application of ointments, circumcision, and appropriate post-operative care and observation. After treatment for foreskin and glans adhesion, patients should also avoid sexual stimulation that may cause penile erection. Adequate rest and avoidance of strenuous physical activities are recommended to facilitate recovery.

What should be done about a child's phimosis?
In general, phimosis in children may be caused by congenital narrowing of the preputial opening, physiological phimosis before puberty, balanitis, incarcerated prepuce, or external urethral orifice stenosis. It is recommended to seek timely medical attention, identify the underlying cause, and then improve the condition under a doctor's guidance through general care, medication, or surgical treatment. In daily life, children should wear loose, breathable cotton underwear.

What are the differences between redundant foreskin and phimosis?
Under normal circumstances, although both phimosis and redundant prepuce involve the foreskin covering the glans, there are clear differences between the two. The main distinctions are体现在 the retractability of the foreskin, exposure of the glans, difficulty in cleaning, symptom presentation, and risk levels. It is recommended to regularly examine the genital area and maintain local hygiene. If phimosis causes discomfort or affects daily life, timely treatment is necessary.

What are the differences between phimosis and redundant foreskin?
In general, the main differences between phimosis and redundant foreskin are reflected in aspects such as their definition and nature, the condition of the foreskin opening, glans exposure, difficulty of daily hygiene, and associated health risks. It is important to distinguish between the two in daily life. If phimosis is present, maintaining local cleanliness is essential to reduce problems caused by accumulation of debris. Additionally, a professional evaluation can help determine whether intervention is necessary.

What causes balanitis (inflammation of the glans penis)?
Balanitis is mainly caused by excessive friction, trauma, candidiasis, eczema, contact dermatitis, and other factors. Underwear that is too stiff or tight, frequent or overly vigorous sexual activity may all lead to prolonged friction on the foreskin, resulting in local damage and subsequent ulceration. To prevent this, avoid excessive friction, choose soft and loose-fitting underwear, and reduce the frequency and intensity of sexual activity.

Is it normal for the foreskin to be connected to a string-like structure?
Under normal circumstances, whether the presence of a line connected to the foreskin is normal needs to be determined based on accompanying symptoms. If there are no discomfort symptoms, it is usually considered normal; however, if pain or bleeding during sexual intercourse is experienced, it may indicate an abnormal condition. If discomfort symptoms occur, it is recommended to seek timely medical consultation at a hospital and undergo standardized treatment under the guidance of a physician.
