What is the reason for something growing inside the urethra?

In real life, the growth of something in the urethra is a common physical disease for many people. There are many reasons for the growth of something in the urethra. Generally, this may be caused by the tissue in the urethra. If there is no redness, swelling or itching, you can continue to observe and pay more attention to personal hygiene and cleanliness.

What causes something to grow inside the urethra?

If there is no pain, itching, redness, swelling or any other feeling, then these are normal urethral mucosal folds and are not a manifestation of disease. The normal male urethra is not a smooth structure, but a curved mucous membrane composed of wrinkles, so urine becomes a line.

Etiology and pathology

Mode of transmission

HPV infection of genital warts is transmitted through sexual contact. Small trauma to the contact site can promote infection. All three types of squamous epithelia (skin, mucosa, metaplasia) are sensitive to HPV infection. Each type of HPV is associated with specific clinical lesions and has its own predilection site on the skin or mucosal squamous epithelium. Infection may occur when shed surface cells or keratin fragments containing relatively large numbers of virus particles enter the clefts of susceptible epithelia. It may be caused by direct contact or, less commonly, automatic inoculation or infection through contaminated underwear, bathtubs, washcloths, or bedpans.

harm

After the virus infects the human body, it can lurk between the basal keratinocytes and replicate in the epidermal cell layer. HPV invades the cell nucleus, causing rapid cell division, accompanied by the reproduction and spread of viral particles, forming characteristic papilloma. In the late stage, the gene expresses structural polypeptides, that is, structural protein assembled particles appear. The virus is mainly concentrated in the cell nuclei in the granular layer. The number of concave cells in the granular layer of the epidermis increases, and histologically normal epithelial cells also have HPV. Residual DNA after treatment can often lead to recurrence of the disease.

Clinical (initial, early) symptoms and characteristics of male genital warts Early symptoms of genital warts - the incubation period is 3 weeks to 8 months, with an average of 3 months. It is more common in sexually active young and middle-aged men and women. The peak age of onset is 20-25 years old. The average course of the disease is 3-5 months for male and female patients. The disease occurs shortly after sexual contact, while the average course of the disease for male patients is 12 months, and their sexual contacts may not develop the disease. Most patients are generally asymptomatic. Lesions vary in size and shape. There may be just a few or many lesions as big as needle heads. They may grow into large tumor-like masses in the anus and vulva, causing a feeling of pressure and a foul odor. Sometimes small condyloma acuminatum may cause pain, itching and discomfort in the vulva, and the patient may have hematuria and difficulty urinating. Condyloma acuminatum in the rectum may cause pain and bloody stools, while large condyloma acuminatum in the rectum may cause a feeling of tenesmus.

In male patients, the disease is more common in the frenulum, coronal sulcus, foreskin, urethra, penis, around the anus and scrotum. At the beginning of the disease, there are light pink or dirty red millet-sized growths that are soft in nature and slightly pointed at the top. They gradually grow larger or increase in number. It can develop into a papillary or cystic shape, with a slightly wider base or bands and granules on the surface. The anus is often enlarged and cauliflower-shaped, with a moist or bleeding surface. Pus often accumulates between the grains, emitting a foul odor. Scratching may lead to secondary infection. Genital warts located in drier areas with lower humidity are often small lesions that appear as flat warts. Warts located in hot, humid areas often appear filamentous or papilloma-like and easily merge into large masses. Warts may enlarge in people with severe liver disease. Pregnancy can cause warts to recur or grow faster.

Subclinical infection refers to lesions that cannot be identified by the naked eye clinically, but topical application or wet compress of 3%-5% acetic acid solution for 5-10 minutes can cause whitening in the HPV-infected area, the so-called "acetic acid whitening phenomenon."
