Urethral nodule

Introduction The urethral nodule is one of the symptoms of paraurethral adenocarcinoma. Early symptoms of paraurethral adenocarcinoma are dysuria, urethral bleeding, frequent urination, and dysuria. A nodular or red hemorrhagic mass appears in the distal urethra or urethra, and local swelling of the urethra can reach the mass. When the tumor is enlarged, it can block the urethra or expand into the vestibular vestibule and vaginal opening, and there are obvious ulcers and hemorrhagic masses, accompanied by pain and possible metastasis of the groin and pelvic lymph nodes. Some scholars believe that urinary tract irritation caused by urination, sexual intercourse, pregnancy or repeated urinary tract infection may be the cause of some urinary tract cancer.

Cause

The etiology of paraurethral adenocarcinoma is not very clear. Some scholars believe that urinary tract irritation may be a cause of urinary tract cancer caused by urination, sexual intercourse, pregnancy or repeated urinary tract infection. Proliferative diseases such as meat mites, papillomas, adenomas, and polyps are secondary to malignant transformation. Urethral leukoplakia is considered a precancerous lesion.

Urine routine urethral function test urethral opening examination

Urine routine examination generally includes 10 items: PRO (protein), RLD or ERY (red blood cells), LEU (leukocyte) is mainly used to diagnose nephritis, kidney stones, urinary tract infection and other diseases, SG (specific gravity), PH (pH) To assess renal tubular function (concentration function and acidification function), GLU (glucose) is used to check renal tubular function and diabetes, NIT (nitrite) positive means bacterial infection in the urinary tract, and KET (ketone body) is used to find diabetic ketone. Acidosis and starvation, BIL (urinary bilirubin), UBG (urinary gallbladder quality) is an auxiliary examination of jaundice, used to identify hemolytic, hepatic and obstructive jaundice. It is necessary to pay special attention to the fact that there is an error in the RLD and LEU measured by the automatic urine tester. Generally, the municipal large hospitals are subject to manual microscopic examination.

Urine color: The color of normal urine is mainly caused by urinary pigment. The daily excretion is generally constant, so the depth of urine color changes with the amount of urine. Normal urine is grassy yellow, and abnormal urine color can be changed by factors such as food, drugs, pigments, and blood.

Transparency: Normal fresh urine, except for women's urine, which is slightly turbid, most of them are clear and transparent. If placed for too long, there will be mild turbidity. This is due to the change of pH in urine, mucus protein and nuclear protein in urine. Gradually precipitated.

If there is an abnormality in the urine routine examination, it is necessary to pay attention to it in a timely manner, and actively seek medical treatment to check the possibility of kidney disease.

Differential diagnosis

1. Early paraurethral adenocarcinoma should be distinguished from urethral meat emulsion. For urethral meat fistula with suspected malignant transformation, biopsy should be performed to confirm the diagnosis.

2. Middle and advanced paraurethral adenocarcinoma should exclude whether the primary lesion is from the vestibule, but the former is adenocarcinoma and the latter is squamous cell carcinoma.

Adenocarcinoma of the urethra can be initially diagnosed according to the symptoms and signs of clinical manifestations; it can be diagnosed when the urethral mass biopsy is adenocarcinoma. The time from symptom onset to diagnosis may be several days, or may be several years, usually 3 to 12 months. In a few cases, patients may have no symptoms. They often find urinary tract cancer by accident to check other diseases. .
