Urethral Cancer

Urethral cancer is a malignant tumor that occurs when the cells lining the inner surface of the tube-shaped channel that carries urine from the bladder outside the body, the urethra, multiply uncontrollably. This rare disease, which develops at the final point of the urinary system, has the potential to progress into surrounding tissues when timely intervention is not provided. Its generally insidious nature during the initial period requires us to be much more attentive even to the smallest changes our body produces in order to protect our overall health. Thanks to early diagnosis and modern medical approaches planned by experienced urology specialists, this disease can be treated with a very high level of success.

What Is Urethral Cancer and Where Does It Begin in Our Body?

Urethral cancer is an important health problem that is quite rare within the broad spectrum of urological cancers but requires a multidisciplinary treatment approach when diagnosed. While kidney, bladder, or prostate cancers are heard of much more frequently in the general population, this disease constitutes only a very small proportion of all urological malignancies. Age is a highly determining factor in the development of the disease; particularly in individuals over the age of sixty, its incidence increases due to cellular aging and the wear and tear tissues are exposed to over the years, and this risk reaches its highest levels in the group over the age of seventy-five. The disease begins with deterioration in the structure of the cells in the thin membrane layer lining the inside of the urethra.

There are cell groups with different structures and characteristics on the inner surface of this channel. When current medical statistics and large-scale databases are examined, it is seen that the disease most commonly originates from cells called urothelial cells, which line a large part of the urinary tract. In addition, there are different types originating from squamous cells resembling the cells that form the skin or from glandular cells capable of producing secretions. The cell type from which the cancer begins is one of the most critical factors determining how rapidly the tumor will grow and which treatment methods it will respond to more positively. Therefore, knowing only the name of the disease is not sufficient; its cellular identity must also be analyzed in detail.

Why Does Urethral Cancer Differ Anatomically in Women and Men?

Human anatomy contains very distinct differences between the sexes in terms of the urinary and reproductive systems. These differences directly affect where the disease begins, how it progresses, and the treatment steps to be planned. In men, the urethra has a much more complex course beyond being merely a urinary channel. This channel, which is approximately twenty centimeters long, first passes directly through the center of the prostate gland immediately after leaving the bladder, then crosses the muscular layer beneath the pelvis and extends along the penis before opening outside the body. In men, this channel is also part of the reproductive system and plays a role in expelling semen from the body. This length and passage through different regions cause cancer to develop in different subregions in men. Tumors with different characteristics may arise in the part passing through the prostate and in the part passing through the penis.

In women, the anatomy is much simpler and shorter. The female urethra is approximately four centimeters long and ends immediately above the vaginal opening, serving only to expel urine from the body. This shortness divides the location of the disease into two main regions: the distal portion opening to the outside and the proximal portion close to the bladder. Tumors developing in the outer portion generally tend to produce symptoms earlier and progress more slowly, whereas tumors developing in the inner portion close to the bladder have the potential to spread more rapidly to surrounding tissues, particularly the anterior wall of the vagina and the pelvic region. These fundamental differences in anatomical structure completely alter the extent and technique of the surgical operations to be performed.

What Are the Main Risk Factors That Lead to the Development of Urethral Cancer?

Although the disease does not have a definite “single cause,” it is scientifically accepted that the primary mechanism initiating cellular deterioration is the exposure of the tissues in the region to chronic irritation and inflammation over many years. When human tissues enter a continuous cycle of damage and wound healing, the likelihood of errors occurring during cell division increases significantly. As these errors accumulate, the process of cancer development begins. In men, urinary tract strictures experienced in the past and repeated medical interventions to open these strictures create serious damage to the urethral wall. In women, benign masses in the urinary tract, skin-tag-like structures, or small pouches in the urinary tract cause urine to stagnate in those areas and continuously produce infection, placing stress on the cellular structure.

In addition, lifestyle habits and environmental exposures deeply affect cellular health. Tobacco use in particular is one of the greatest dangers because toxic substances taken into the body are filtered through the kidneys, pass into the urine, and come into contact with the urethral wall while being expelled through the urinary tract. Furthermore, some sexually transmitted virus types classified as high risk may integrate directly into cellular DNA and force the tissues toward cancerous transformation.

The main risk factors that may trigger the development of the disease are as follows:

• Advanced age
• Smoking
• Chronic urethral stricture
• Frequently recurring urinary tract infections
• Human Papillomavirus (HPV)
• History of radiotherapy to the pelvic region
• Continuous urinary catheter use
• Urethral diverticula
• Urethral caruncles
• History of other urological cancers

What Symptoms Does Our Body Produce in the Early Stages of Urethral Cancer?

One of the most challenging aspects of the disease is that it does not cause pain or obvious discomfort severe enough to compel the person to visit a doctor during the initial stage. While the tumor is still very small, it begins to grow silently inside the urinary channel. Most people tend to ignore minor changes related to the urinary system by attributing them to a temporary chill, insufficient water intake, or a simple infection. However, our body always sends signals when something is going wrong internally. Reading these signals correctly and undergoing medical evaluation without delay is the key to detecting the disease at its earliest treatable stage.

The first finding that requires the greatest attention and should never be neglected is blood in the urine. This bleeding may sometimes be bright red or brown and clearly visible in the toilet, while at other times it may be microscopic, invisible to the naked eye, and detected only in a routine laboratory test. Bloody or purulent discharge noticed in the underwear independently of urination is also a very important warning sign. As the tumor gradually grows and begins to narrow the diameter of the urinary channel, mechanical changes occur in urinary habits. The person notices that urination is no longer as comfortable or forceful as before. The inability to empty the bladder, the sensation that urine remains inside, and the resulting increase in the frequency of toilet visits begin to reduce quality of daily life.

The most common early-stage symptoms encountered during the initial stages of the disease are as follows:

• Blood in the urine
• Bloody discharge from the urinary opening
• Weakening of the urine stream
• Split urine stream
• Intermittent urination
• Frequent urination
• Waking at night to urinate
• Sudden urinary urgency
• Urinary incontinence

What Are the Clinical Symptoms of Advanced-Stage Urethral Cancer?

If the disease cannot be detected during the early period and the tumor continues to grow uncontrollably, it begins to extend beyond its narrow boundaries into the surrounding muscles, connective tissues, and organs. At this stage, the symptoms are no longer limited to difficulty urinating; visible and palpable physical changes are also added to the condition. In men, unusual hardness in the shaft of the penis, thickening of the tissue, or palpable masses in the perineal region may appear. In women, firm swellings that may be painful when touched or sometimes completely painless become apparent immediately around the vaginal opening.

The more the tumor tissue infiltrates the surrounding tissues, the greater the pressure it places on the nerve endings in that region. This pressure may cause deep and severe pain in the pelvic region, particularly during or after sexual intercourse in women. The next route followed by cancer cells is the body’s lymphatic system. Cells entering the lymphatic vessels around the urethra reach the lymph nodes in the groin region, their first destination. These nodes, which are the body’s defense stations, begin to swell when invaded by cancer cells. Lumps appearing in the groin that are generally painless but gradually enlarge and feel hard as stone are among the clearest indicators that the disease has exceeded its local boundaries and requires a more systemic approach.

Advanced-stage symptoms that may occur when the disease progresses and spreads to surrounding tissues are as follows:

• Hardness in the shaft of the penis
• Sensation of a mass in the perineal region
• Painful swelling around the vagina
• Pelvic pain during sexual intercourse
• Enlarged lymph nodes in the groin region
• Painless lumps in the groin

Which Benign Diseases Can the Symptoms of Urethral Cancer Be Confused With?

The vast majority of urinary tract problems arise from benign causes other than cancer. Although this is reassuring for patients, it requires great attention during the diagnostic stage. This is because complaints caused by urethral cancer, such as bleeding, frequent toilet visits, burning during urination, or weakening of the urine stream, are identical to complaints caused by prostate enlargement, cystitis related to a chill, or simple urinary tract inflammation. When the patient experiences these symptoms, they generally expect the problem to resolve by using antibiotics or similar medications. If the complaints persist stubbornly despite standard infection or prostate treatments, a more serious underlying condition should be suspected.

There are some rare conditions that must be considered very carefully in the differential diagnosis and that perfectly mimic cancer. The accumulation of certain protein structures in the urinary channel that have no relationship with cancer may form a mass and be confused with a tumor in terms of both the patient’s complaints and examination findings. Even when examined internally with a camera, the true nature of these masses that resemble cancer can only be revealed through detailed pathological examination at the cellular level. Major and irreversible surgical procedures performed without making the correct distinction, meaning without obtaining definitive evidence, may unnecessarily cause major losses in the patient’s life.

The main benign conditions considered in the differential diagnosis that cause similar complaints are as follows:

• Benign prostatic enlargement
• Urinary tract infections
• Urethritis (inflammation of the urinary tract)
• Benign urinary tract strictures
• Primary localized urethral amyloidosis

What Diagnostic Methods Are Used for the Definitive Diagnosis of Urethral Cancer?

When a person presents with persistent and unresolved complaints, a systematic diagnostic process progressing step by step is initiated to establish the exact name of the disease. The aim of this process is to obtain the most accurate data in the shortest possible time without exhausting or frightening the patient. The process begins with the physician listening to the patient and performing a detailed physical evaluation. During external manual examinations, hardness in the surrounding tissues, the condition of the lymph nodes, and the health of the area where the urinary tract opens outside the body are checked. Organ functions are evaluated through routine blood and urine tests. Cellular debris shed into the urine is even examined under a microscope to determine whether there is any trace of cancer.

However, all these procedures are only clues that strengthen suspicion. The way to reach a definitive diagnosis is to directly observe the inside of the urinary tract. Using very thin, flexible instruments equipped with high-resolution cameras at their tips, the entire inner surface of the channel is examined in detail on large screens by entering through the urinary opening. Since the procedure is performed with gels that provide local anesthesia, it is quite comfortable. If an abnormal, reddened, raised, or mass-like suspicious area is seen inside, tiny tissue samples approximately the size of a lentil are taken from that area using special fine instruments. These tissues are analyzed at the microscopic level in the pathology laboratory. The presence of the tumor, cell type, and degree of aggressiveness become clear only as a result of this examination.

The basic steps applied during the diagnostic process are as follows:

• Detailed physical examination
• Blood tests
• Urine cytology
• Cystourethroscopy
• Tissue biopsy
• Pathological examination

How Are the Staging and Radiological Imaging Processes of Urethral Cancer Performed?

After the definitive diagnosis is established, determining whether the disease has remained confined only within the urethra or has traveled to other parts of the body is of vital importance. This determination process is called staging and is the most important stage in drawing the treatment map. Advanced imaging devices are used to understand the size of the cancer and the depth it has reached. Advanced magnetic resonance imaging (MRI) devices are used to determine with millimetric precision how far the tumor has penetrated the surrounding spongy tissues, prostate gland, vagina, or pelvic muscles. This is because cancer may have rooted into deeper tissues even if it appears small on the surface.

Detailed tomography procedures that scan the entire body are also performed against the possibility that the disease may have spread to distant organs such as the liver, lungs, or bones by using the lymphatic system or blood vessels. All the data obtained are combined according to an internationally standardized system. The disease is classified from Stage 1 to Stage 4 by evaluating the size of the tumor, its spread to the lymph nodes, and whether it has spread to distant organs. While Stage 1 disease refers to a completely superficial condition confined to its original location, Stage 4 describes a much more complex condition in which the disease has reached distant parts of the body. The intensity and extent of treatment are shaped entirely according to these staging results.

The main imaging methods used to determine the extent of the tumor are as follows:

• Magnetic Resonance Imaging
• Computed Tomography
• Transvaginal ultrasonography
• Superficial ultrasonography
• Bone scintigraphy

What Are the Surgical Treatment Methods for Urethral Cancer in Male Patients?

Surgical intervention is the primary and most powerful treatment method used to completely remove the disease from the body and restore the patient’s health. In male patients, the main factor determining how the operation will be performed is the location of the tumor within the urinary tract. If the disease is located in the distal portion passing through the penis and is at an early stage before penetrating deeply into the tissues, procedures aimed at preserving the structure and functions of the organ at the highest possible level are applied. In such cases, limited surgeries in which only the tumor-containing area and a small safety margin immediately around it are removed, while the remaining healthy parts of the penis are preserved, can be performed successfully. After the procedure, the urinary tract is connected to the perineal region behind the testicles through a new opening so that urine can be expelled safely.

However, if the disease is located deep within the pelvis in the proximal portion close to the prostate and has progressed into the surrounding tissues, the extent of surgery must necessarily be expanded. To avoid leaving even a single cancerous cell in the body, extensive operations in which the prostate, bladder, and necessary tissues are completely removed may be performed according to the situation. Naturally, if the bladder is removed, the patient requires a new system to store and expel urine from the body. At this stage, a new urinary bladder is created using sections taken from the patient’s own intestines, or the urinary tract is connected to the abdominal wall and urine drainage is provided through special bag systems. These complex processes require highly delicate reconstructive skills that rebuild functions.

The main surgical methods applied in male patients according to the location and stage of the tumor are as follows:

• Partial penectomy
• Perineal urethrostomy
• Radical cystoprostatectomy
• Radical penectomy
• Pelvic lymph node dissection
• Ileal neobladder (new bladder)
• Urostomy (stoma)

What Are the Surgical Treatment Options for Urethral Cancer in Female Patients?

The very short length of the female urinary tract clearly divides the nature of the operations to be performed into two categories according to the location of the tumor. If the tumor is in the distal region very close to the vaginal opening and is detected at a very early stage, organ-preserving surgeries that provide highly favorable results for female patients may be performed. In this case, only the distal portion of the urinary tract is removed locally, while the remaining healthy part of the urinary tract is preserved, allowing the patient to continue daily life and urinary functions with minimal damage.

However, if the disease is located in the proximal portion toward the bladder, wider safety margins are required because of the narrow anatomical relationships and intertwined structure of the tissues in that region. Tumor cells may rapidly infiltrate the anterior wall of the vagina, bladder neck, and lymph nodes within the pelvis. Therefore, more extensive operations are performed in which the bladder, the entire urinary tract, and sometimes part of the anterior vaginal wall are removed together to eradicate the disease completely. In place of the removed organs, special diversion procedures are planned using new channels created from the small intestine so that urine can safely leave the body. The primary aim is always to maintain the patient’s oncological safety at the highest level while completely eliminating the disease.

The surgical approaches preferred in female patients according to the condition of the disease are as follows:

• Local excision
• Anterior vaginectomy
• Radical cystourethrectomy
• Pelvic lymphadenectomy
• Urinary diversion procedures

What Are the Advantages of Robotic and Laparoscopic Methods in the Surgical Treatment of Urethral Cancer?

In previous years, large incisions that required a long time to heal had to be made in patients’ abdominal regions to reach the organs located deep within the pelvis and remove cancers in these areas. However, revolutionary changes have occurred in medicine with the integration of modern technology into operating rooms. Today, minimally invasive operations can be performed by creating only several millimeter-sized openings in the patient’s abdomen and using advanced camera systems and fine-tipped instruments. Robotic surgical systems in particular provide the operating team with a magnified, three-dimensional, and exceptionally clear field of vision beyond what the human eye can see.

Robotic arms directed from the surgical console have much greater maneuverability than the human hand and completely eliminate natural hand tremors. This provides an enormous advantage, particularly around blood vessels and nerves that require millimetric precision. While cancerous tissues are removed, the very fine nerve networks that control urinary continence and sexual functions can be preserved with great care. From the patient’s perspective, not cutting the abdomen from one end to the other means much less blood loss, a significant reduction in the risk of infection, and minimizing postoperative pain. Patients stand up much sooner, are discharged from the hospital earlier, and adapt to their daily lives with their loved ones much more rapidly.

The most important advantages that minimally invasive surgical technologies provide to patients are as follows:

• Smaller incisions
• Minimal tissue damage
• Less blood loss
• Less postoperative pain
• Shorter hospital stay
• Faster return to daily life
• Precision of nerve-sparing techniques
• Better preservation of erectile functions

What Additional Non-Surgical Methods Are Used in the Treatment of Advanced-Stage Urethral Cancer?

Success in cancer treatment is achieved not with a single weapon but by using all available modern oncological methods in a complementary manner. Sometimes the mass may be too large to remove surgically or may be attached to locations that make surgery risky. In such cases, neoadjuvant chemotherapy treatments are applied before surgery to shrink the mass, make the operation safer, and increase surgical success. Even when the operation is highly successful, adjuvant chemotherapy support may be provided afterward to completely eliminate cellular remnants that are invisible to the naked eye and may circulate in the blood.

In addition, radiotherapy, radiation treatment, in which high-energy beams are directed precisely at the specific area where the tumor is located, may be added to the treatment plan to prevent the disease from becoming active again, recurring, in that area in later years. Another groundbreaking development in oncology in recent years is immunotherapy. These innovative medications, used particularly in cases resistant to other treatments or those that have spread to distant organs, train the body’s own immune system cells and enable them to attack cancerous tissues directly. All these methods are parts of a comprehensive strategy specially designed for the patient’s condition by expert oncologists working together.

Other oncological treatments planned by the tumor board and applied in addition to surgery are as follows:

• Neoadjuvant chemotherapy
• Adjuvant chemotherapy
• Radiotherapy (radiation treatment)
• Immunotherapy agents
• Active surveillance protocol

What Awaits Patients During the Recovery Process After Urethral Cancer Surgery?

Cancer treatment is a multidimensional recovery process in which patients not only fight the disease but also adapt to changes in their bodies. After extensive operations, the body needs time to recover, the sutures need to heal, and the patient must adapt to the new anatomical arrangement. After surgery, patients are generally sent home with a urinary catheter for a period so that the urinary tract can heal safely. After the catheter is removed, narrowing may sometimes develop in the urinary channel due to the natural healing process of the tissues. When these strictures caused by healing scar tissue lead to a reduction in urinary pressure, these areas are widened with short minimally invasive endoscopic procedures, allowing the patient to urinate comfortably again.

In addition, temporary or permanent changes in sexual functions may occur in some patients after operations in the pelvic region. When erectile problems develop in men, a wide range of highly successful treatment options are available, ranging from oral medications and local treatments administered into the penis to prostheses known as penile implants. In the early period, the hospital team performs strict wound care to prevent infection at the surgical site and avoid minor bleeding or urine leakage. The recovery process develops according to each patient’s own biological pace, and every functional problem encountered during this journey has a corresponding medical solution.

Possible conditions and complications that may be encountered after surgery are as follows:

• Urethral stricture
• Urinary tract infections
• Erectile dysfunction
• Ejaculatory disorders
• Surgical site bleeding
• Urine leakage
• Vaginal narrowing

What Should Patients Pay Attention to in Their Daily Lives After Urethral Cancer Treatment?

When difficult treatment processes have been left behind and health has largely been restored, maintaining this state of well-being is in the patient’s hands. Positive lifestyle changes not only enable the body to recover more rapidly but also minimize the risk of the disease recurring in the future. The most indispensable rule of this process is to keep the urinary system continuously active and clean. Consuming plenty of fluids throughout the day creates a natural flushing effect in the urinary tract, keeping infections and possible crystallization away.

Another vital issue at least as important as drinking water is completely avoiding tobacco products. The chemicals in cigarettes significantly delay wound healing by reducing the amount of blood reaching the tissues, and because they mix with the urine, they also create a new carcinogenic threat to the remaining healthy tissues. Paying attention to nutrition during the recovery period, maintaining personal hygiene at the highest level, and avoiding stress keep the immune system strong. Oncological processes require psychological resilience as much as physical strength; therefore, receiving family support and seeking professional psychological counseling when necessary enable the process to be managed much more healthily. Most importantly, even after overcoming the disease, regular medical appointments and follow-up imaging procedures should never be neglected.

The points that should be considered in daily life for a healthy recovery process and long-term protection are as follows:

• Consuming plenty of water
• Surgical site hygiene
• Completely quitting smoking
• Avoiding environments where smoking occurs
• Regular medical checkups
• Not neglecting cystoscopy follow-ups
• Receiving psychological support
