The external urethral orifice is the opening of the urethra located at the tip of the penis in men and above the vaginal opening in women. Cancer in this region, though rare, can occur and is known as external urethral orifice cancer. This article will provide a comprehensive guide to understanding the disease, its causes, symptoms, diagnosis, treatment options, and preventive measures, using simple language to make it accessible and easy to understand.
External urethral orifice cancer is a type of cancer that occurs in the urethra’s external opening. The urethra is the tube through which urine passes from the bladder to the outside of the body. Cancer in this area can affect both men and women, although it is more common in women. It is often classified as a rare and aggressive cancer that requires immediate medical attention and treatment.
Pathophysiology (Structure, Blood, Nerve Supply)
Structure of the Urethra:
- The urethra is divided into different parts: the bladder neck, prostatic urethra, membranous urethra, spongy (penile) urethra, and external urethral orifice. The external opening is located at the end of the spongy urethra.
Blood Supply:
- The blood supply to the urethra comes from small branches of the internal pudendal artery, the inferior vesical artery, and other smaller arteries.
Nerve Supply:
- The urethra is innervated by the autonomic nervous system, including the parasympathetic and sympathetic nerves, as well as sensory nerves from the pelvic region.
Types of External Urethral Orifice Cancer
External urethral orifice cancer can be classified into different types based on the cells affected:
- Squamous Cell Carcinoma: The most common type, originating in the squamous cells that line the urethra.
- Adenocarcinoma: A rarer type that begins in the glandular cells.
- Transitional Cell Carcinoma: Occurs when the cancer forms in the transitional cells that line the urethra.
Causes of External Urethral Orifice Cancer
Although the exact cause is not always clear, several factors are known to increase the risk of developing cancer in the external urethral orifice. These include:

- Trauma to the urethra.
- Smoking and tobacco use.
- Age (more common in older adults).

Diagnostic Tests for External Urethral Orifice Cancer
To diagnose external urethral orifice cancer, doctors may use the following tests:
- Physical examination.

- Cystoscopy (a camera inserted into the urethra to examine the urinary tract).
- Biopsy (removal of tissue to test for cancer cells).
- MRI (Magnetic Resonance Imaging) of the pelvis.
- CT scan (Computerized Tomography) for detailed imaging.
- Ultrasound of the pelvic region.
- Urethroscopy (a detailed examination of the urethra).
- Urine cytology (testing urine for abnormal cells).
- Blood tests (for markers of infection or cancer).
- Chest X-ray to check for spread of cancer.
- Lymph node biopsy.
- PET scan (Positron Emission Tomography).
- Genetic testing for hereditary cancers.
- Flow cytometry for cell analysis.
- Urodynamics (testing the bladder’s ability to hold and release urine).
- Electromyography to assess nerve function.
- Endoscopic examination.
- Laparoscopy to examine internal organs.
- X-ray of the bones to check for metastasis.
Non-Pharmacological Treatments for External Urethral Orifice Cancer
Non-pharmacological treatments aim to alleviate symptoms and support recovery. These treatments include:
- Lifestyle changes (quit smoking).

- Palliative care for advanced cancer.
- Heat therapy for pain management.
- Avoidance of irritants (e.g., certain soaps or chemicals).
- Supportive therapies like acupuncture.
- Stress management through yoga or meditation.
- Skin care around the urethral opening.
