What Is Urethral Cancer?

Urinary tract cancer is a urethral epithelial tumor, which is relatively rare in clinical practice. Most male urethral cancers are over 40 years old, and female urethral cancers are more common in the elderly. About 50% of urinary tract cancers are secondary to bladder, ureter, or transitional epithelial cancer of the renal pelvis. Primary urethral cancer is relatively rare and occurs mainly in women.

Multiple groups

Common symptoms

Urethral obstruction, mass, periurethral abscess, urethral bleeding, and hematuria

Causes of urethral cancer

The cause of urethral cancer is not clear, but it has nothing to do with the possibility of urethral sarcoidosis. The leukoplakia may be a precancerous lesion. The early stage of urethral cancer is similar to urethral sarcoidosis, polyps and papilloma, and it should be identified. If necessary, living tissue an examination.

Clinical manifestations of urethral cancer

Male urethral cancer is usually treated with urethral obstruction, mass, periurethral abscess, extravasation, urethral fistula, and urethral discharge. Some patients have pain, hematuria, or hematoma.

Female urethral cancer is more common in older women. Common symptoms are urethral bleeding and hematuria. Other symptoms include frequent urination, dysuria, burning urination, difficulty urinating, or pain during sexual intercourse. Lumps can be seen or touched locally. Tumor necrosis, ulcers, infections can be seen in the urethra or vagina with yellow or bloody odorous secretions. Advanced symptoms are weight loss, pelvic pain, periurethral abscess, urinary incontinence, urethral vaginal fistula, or urinary retention.

Urethral cancer examination

1. The urethra bleeds and the urethra touches the mass.

2. Urethral angiography showed filling defect in the urethra.

3. The urethroscopy showed a tumor and biopsy confirmed the tumor.

4. Cancer cells were detected in urine and urethral secretions.

Urethral cancer treatment

Early

Early total urethral resection, partial or total resection of the penis and lymphadenectomy can be performed when the tumor infiltrates the urethra. Male posterior urethral and female urethral cancers require bladder and urethral resection and urinary diversion.

2. Late

(1) Chemotherapy is mostly used for palliative treatment, and the effect is not certain.

(2) Radiation therapy has external and internal irradiation. Radiotherapy for small-stage small tumors is satisfactory. Radiotherapy for large and high-stage posterior urethral cancer is not effective. Common complications include urethral stricture, local necrosis, vulvar abscess, and radiation pelvic cavity. Yan and so on.
