thickened urethra
Introduction
Introduction Caused by urethral tumors. The cause of urinary tract tumors is still unclear, and may be associated with sexual stimulation, menstrual paper friction, birth trauma, urinary tract infections, and some existing genital lesions, such as leukoplakia, urethral meat, urethral polyps, chronic urethritis, urethra Stenosis is associated with incentives such as repeated urethral dilation, and the age of onset is between 40 and 60 years old. Urethral tumors include male urethral cancer and female urethral cancer. Male urethral cancer has different primary sites, and most of them are transitional epithelial cancer and squamous cell carcinoma. Primary female urethral tumors are almost malignant, less common, but their incidence is 4-5 times higher than that of males. There are multiple middle-aged and elderly patients, which are divided into female distal urethral cancer and female proximal urethral cancer.

1. Frequent urination, difficulty urinating, fine urinary flow, tingling of the urethra and bloody secretions.
2. X-ray examination, proximal urethral cancer can directly invade the pubic bone to cause bone destruction, lymphangiography is helpful for the diagnosis of pelvic lymph node metastasis.
3. Cytological examination, take morning urine for exfoliated cell examination, or use urethral swab to extend into the urethra and rub, take exfoliated cells for examination.
4. Urethoscopy and biopsy confirmed tumors.
5. Vaginal finger examination, the urethra can be licked and lumps, the urethra becomes thicker and harder. Males can touch the urethral mass along the urethra or through the rectal examination. Urethral angiography has a urethral filling defect. If the above symptoms occur, you should go to the hospital for urinary tract tumor treatment in time to avoid more damage.
Diagnosis
Differential diagnosis
1. Before the operation, the nature of the tumor should be as clear as possible. Generally, the lower urinary tract is easier to clear than the upper urinary tract before surgery, because biopsy can often be obtained by bladder urethra. In most cases, a clear diagnosis depends mainly on postoperative pathological examination.
2. Using B-ultrasound and IVI and bladder urethroscopic and other methods of sputum surgery, such as the nature of the lesions, the location of the lesions and the impact of the lesion on the kidney function.
3. If the tumor is large or may infiltrate into the urinary tract lumen, CT or MRI should be performed to accurately understand the extent of the lesion, lymph node, tissue and surrounding blood vessels involved.
4. According to the location of the tumor in the urethra, the laser urethral tumor treatment is also different. If the tumor is confined to the distal side of the penis, the tumor site and volume are determined, and Nd:YAG quartz fiber is introduced and output laser treatment. Use power 40~50W, adjust according to the patient's cancer. When the main tumor is destroyed, the local high temperature spreads to the periphery and has an indirect killing effect on the residual cancer cells, and it is not necessary to perform partial penile resection like traditional surgery. Due to the special efficacy of the laser, the author observed many cases of malignant tumors with different clinical manifestations after laser surgery. The tumors disappeared completely and the local compensatory repairs were good. Some patients needed organ resection, which finally promoted the complete organs and functions. No change. The urethral prostate tumor is resected transurethrally under cystoscopy. Because urethral bulb tumors have been extensively expanded at the time of diagnosis, it has been reported that even radical surgery cannot be cured.
