Uro-Oncology: What Is It and Which Urological Cancers Does It Treat?

Every year, millions of people experience one of the most difficult turning points of their lives with a cancer diagnosis. In this difficult struggle, certain fields of medicine, especially in the fight against cancer, play a leading role. Uro-oncology is one of these vital fields and focuses on cancer types affecting the male reproductive system and the kidneys, bladder, and urinary tract in both men and women. This multidisciplinary field aims to offer patients comprehensive treatment by bringing together different specialties such as surgery, medical oncology, and radiation oncology. So, what exactly is uro-oncology and which specific diseases does it deal with? Let us examine this important medical discipline in depth.

Although uro-oncology is a relatively new field in medical literature, it has developed rapidly with advances in the early diagnosis and treatment of cancer. The main aim of this field is to optimize the diagnosis, treatment, and follow-up of urogenital system cancers. Uro-oncology specialists use the most up-to-date treatment methods to improve the quality of life and increase survival rates of patients struggling with these complex diseases. In this process, benefiting from innovations offered by technological developments (such as robotic surgery and immunotherapy) is also of great importance. The scope of uro-oncology covers a wide range, from prostate cancer, one of the most common male cancers, to rarer types such as kidney or bladder cancer that affect both men and women. Early diagnosis of these diseases is critically important for treatment success.

The Historical Development and Importance of Uro-Oncology

The origins of uro-oncology are based on the intersection of the fields of urology and oncology. In the past, urogenital system cancers were generally handled by general surgery or urology departments. However, the complexity of cancer and the necessity of specific treatment approaches created a need for specialization in this field. From the mid-20th century onward, developments in cancer treatment and advances in surgical techniques paved the way for uro-oncology to take shape as a separate discipline. Especially intensive research on prostate cancer and the development of new treatment strategies accelerated the development of this field.

Today, uro-oncology plays a key role in the fight against cancer. The multidisciplinary approach offered by this field ensures that patients reach the most appropriate treatment plan. A uro-oncology team generally consists of specialists such as a uro-oncologist (urology specialist), medical oncologist (doctor managing chemotherapy and targeted treatments), radiation oncologist (doctor applying radiation therapy), pathologist (doctor examining tissue samples), and radiologist (doctor interpreting imaging techniques). This collaboration is vitally important in determining personalized treatment strategies most suitable for the patient’s condition. For example, in prostate cancer treatment, different approaches such as surgical options, radiotherapy, or hormone therapy are evaluated according to factors such as the patient’s general health condition, cancer stage, and aggressiveness.

The importance of this field is not limited only to success rates in the fight against cancer. Uro-oncology also aims to preserve patients’ quality of life and minimize post-treatment side effects. Possible treatment-related problems such as urinary incontinence and sexual dysfunctions are issues carefully managed by uro-oncology specialists. Therefore, uro-oncology continues to be a ray of hope for cancer patients. Institutions such as the Source: American Urological Association support developments in this field by publishing current research and treatment guidelines in uro-oncology.

Diseases Covered by Uro-Oncology

Uro-oncology covers both cancerous and some important non-cancerous diseases of the urogenital system. These diseases may affect both men and women, and some are specific only to men. Understanding this distinction is important for directing patients to the correct specialist. Although the main focus of uro-oncology is cancer, sometimes conditions that may be precursors of these cancers or cancer-related complications may also fall within the area of interest of this field.

Male Reproductive System Cancers

Male reproductive system cancers are one of the most important focus areas of uro-oncology. These cancers may directly affect men’s quality of life and reproductive health.

• Prostate Cancer

Prostate cancer is one of the most common cancer types in men. The prostate gland is a small organ located under the bladder and produces part of the seminal fluid. Prostate cancer generally grows slowly and may not cause symptoms in the early stages. Therefore, regular screenings are of great importance. Uro-oncology specialists are specialized in the early diagnosis, staging, and treatment of prostate cancer. Treatment options include active surveillance, surgery (prostatectomy), radiotherapy, hormone therapy, and chemotherapy. Minimally invasive techniques such as robotic surgery are increasingly used to accelerate the recovery process and reduce side effects. The Source: National Cancer Institute provides detailed information about prostate cancer.

• Testicular Cancer

Testicular cancer is a type of cancer that develops in the testes, the male reproductive glands. It is generally seen in young and middle-aged men. Symptoms may include painless swelling or mass in the testicle, a feeling of heaviness in the testicle, groin pain, or tenderness. Testicular cancer is a highly treatable cancer when diagnosed early. Uro-oncology specialists manage the diagnosis, surgical treatment (orchiectomy), chemotherapy, and radiotherapy processes of testicular cancer. Advanced surgical techniques such as lymph node dissection may also be applied according to the stage of the disease.

• Penile Cancer

Penile cancer is a rare type of cancer and starts in the skin of the penis or in the cells forming the structure of the penis. It is generally seen at advanced ages and is associated with risk factors such as HPV (Human Papilloma Virus) infection, lack of hygiene, and being uncircumcised. Symptoms may include a wound, spot, thickening, or discharge on the penis. Early diagnosis is critical for preservation of the penis and treatment success. Uro-oncology specialists play a role in the surgical treatment of penile cancer (partial or total penectomy), radiotherapy, and chemotherapy applications.

Cancers Affecting Both Men and Women

Uro-oncology is not limited only to male-specific cancers; cancers affecting the kidneys, bladder, and urinary tract can be seen in both men and women.

• Kidney Cancer (Renal Cell Carcinoma)

Kidney cancer is a disease that occurs with uncontrolled growth of cells in the kidneys. The most common type is renal cell carcinoma. Symptoms may include bloody urine, flank pain, abdominal mass, fatigue, and weight loss. However, it may not cause symptoms in the early stages. Uro-oncology specialists play an important role in the diagnosis, staging, and treatment of kidney cancer. Treatment options include surgery (nephrectomy – partial or complete removal of the kidney), targeted therapies, and immunotherapy. Robotic surgery is becoming increasingly popular in kidney cancer treatment.

• Bladder Cancer (Urothelial Carcinoma)

Bladder cancer is a type of cancer that starts in the cells lining the inner surface of the bladder (urothelium). The most common symptom is bloody urine, which is usually painless. Symptoms such as burning during urination, frequent urination, or inability to urinate may also be seen. Smoking is one of the most important risk factors for bladder cancer. Uro-oncology specialists are involved in the diagnosis, staging, and treatment of bladder cancer. Treatment varies depending on the stage and depth of the cancer. While transurethral resection (TUR-M) and intravesical drug applications are used for superficial bladder cancers, radical cystectomy (removal of the bladder) and chemotherapy/radiotherapy may be required for more invasive cancers.

• Ureter Cancer and Renal Pelvis Cancer

Ureter cancer is a rare type of cancer that develops in the ureter, the tube that carries urine from the kidney to the bladder. Renal pelvis cancer occurs in the area where the kidney collects urine and connects to the ureter. Both generally originate from urothelial cells and show similar characteristics to bladder cancer. Symptoms such as bloody urine and flank pain may be seen. Treatment of these cancers generally includes surgery (nephroureterectomy – removal of the kidney and ureter) and sometimes chemotherapy.

• Urethral Cancer

Urethral cancer is a rare type of cancer that develops along the urethra, the canal through which urine is expelled from the body. It can be seen in both men and women. Symptoms may include pain during urination, bleeding, changes in urine flow, or a mass around the urethra. Its treatment varies depending on the location and stage of the cancer and may include surgery, radiotherapy, or chemotherapy.

Non-Cancerous Urological Diseases (May Be Uro-Oncology-Focused in Some Cases)

Although the main focus of uro-oncology is cancer, some conditions that may be associated with cancer or increase cancer risk may also fall within the area of interest of this field.

• Benign Prostatic Hyperplasia (BPH)

Benign prostatic hyperplasia (benign prostate enlargement) is not prostate cancer, but it may cause symptoms similar to prostate cancer (such as frequent urination and weakening of urine flow). Therefore, uro-oncology specialists may play a role in the evaluation of these symptoms, especially in older men. It is important that BPH is not confused with cancer and that the correct diagnosis is made.

• Urinary Tract Infections (Recurrent or Complicated Ones)

Recurrent or treatment-resistant urinary tract infections may be a sign of another underlying problem. Rarely, these infections may be associated with cancer or may occur as a side effect of cancer treatment. In such cases, uro-oncology specialists may investigate the cause of the infection.

• Urinary System Stones (Complicated Conditions)

Although kidney or bladder stones generally fall within the field of urology, in some cases stone formation may be associated with cancer or may complicate cancer treatment. In such complex cases, evaluation by uro-oncology specialists may be required.

Diagnostic Methods in Uro-Oncology

Accurate and early diagnosis in uro-oncology is the most important factor that directly affects treatment success. Therefore, various diagnostic methods are used to comprehensively evaluate the patient’s condition. These methods cover a wide range, from understanding symptoms to determining the spread of the disease.

Blood Tests

Blood tests are one of the first steps in the diagnosis of many uro-oncological diseases. These tests may provide clues about the presence or progression of the disease by measuring the levels of certain chemicals or proteins in the body.

• Prostate Specific Antigen (PSA) Test: It is the most commonly used test in prostate cancer screening and follow-up. PSA is a protein produced by the prostate gland. PSA levels may increase in conditions such as prostate cancer, prostatitis (inflammation), or benign prostatic hyperplasia. High PSA values increase suspicion of cancer but do not provide a definitive diagnosis; additional tests are required.
• Tumor Markers: Specific tumor markers for other uro-oncological cancers such as kidney cancer, bladder cancer, or testicular cancer may also be examined with blood tests. For example, markers such as alpha-fetoprotein (AFP) and beta-hCG are used in testicular cancer. These markers help monitor the presence, type, and response to treatment of cancer.

Urine Tests

Urine tests are used to detect urinary tract infections, the presence of blood, and cancer cells.

• Complete Urinalysis: Evaluates the presence of blood cells, proteins, bacteria, and other substances in the urine. Bloody urine (hematuria) may be an important symptom of bladder or kidney cancer.
• Urine Cytology: Microscopic examination of abnormal cells in the urine. It is especially useful in the early diagnosis of bladder cancer.

Imaging Methods

Imaging techniques allow detailed visualization of the internal structure of the urogenital system and detection of cancerous tissues. These methods are critically important in determining the size, location, and spread of the disease.

• Ultrasonography (USG): Provides imaging of organs such as the kidneys, bladder, and prostate using sound waves. It is especially used in evaluating kidney masses, thickening in the bladder wall, and prostate size. It is also one of the first methods used in suspected testicular cancer.
• Computed Tomography (CT): An X-ray-based imaging method that creates cross-sectional images of the body. It is very effective in determining the spread of kidney, bladder, and prostate cancers and whether they have spread to lymph nodes or other organs. CT angiography may be used to examine kidney vessels in more detail.
• Magnetic Resonance Imaging (MRI): Creates detailed body sections using strong magnetic fields and radio waves. It may be superior to CT especially in staging prostate cancer and determining the characteristics of kidney masses. MR urography is used in imaging the urinary tract.
• Positron Emission Tomography (PET-CT): Performed by injecting a radioactive substance that shows metabolic activity in the body. Since cancer cells generally have higher metabolic activity, PET-CT is very sensitive in detecting the spread of cancer in the body (metastases). It is especially used in determining recurrence or spread of prostate cancer.
• Scintigraphy: Bone scintigraphy is used to check whether cancer has spread to the bones.

Biopsy

Biopsy is the most important method for confirming a cancer diagnosis. It is the examination of a small sample taken from suspicious tissue under a microscope by pathologists.

• Prostate Biopsy: Samples are taken from prostate tissue with biopsy performed under ultrasonography or MRI guidance. These samples determine the presence, grade (Gleason score), and aggressiveness of the cancer.
• Kidney Biopsy: Performed to understand whether masses detected in the kidney are benign or malignant.
• Bladder Biopsy: Usually taken from suspicious lesions during transurethral resection (TUR-M).
• Lymph Node Biopsy: A sample is taken from lymph nodes suspected of cancer to investigate whether there is metastasis.

Endoscopic Methods

Endoscopy is the direct visualization of the inside by placing a thin, flexible tube (endoscope) into body cavities or organs.

• Cystoscopy: Examination of the inside of the bladder. It is used in patients with suspected bladder cancer, when there are signs of bleeding or irritation in the urinary tract. Biopsy may be taken from suspicious areas during cystoscopy.
• Ureteroscopy: Examination of the ureters (urinary canals). It is used in suspected kidney stones or ureter cancer. During this procedure, biopsy may also be taken or small stones may be removed.
• Urethroscopy: Examination of the urethral canal.

One or more of these diagnostic methods are determined by the uro-oncology specialist according to the patient’s symptoms, physical examination findings, and initial test results. The aim is to detect the disease at the earliest stage and create the most accurate treatment plan.

Treatment Approaches in Uro-Oncology

Treatment in uro-oncology varies greatly according to the type and stage of cancer, the patient’s general health condition, and personal preferences. The aim is to eliminate cancer, prolong the patient’s lifespan, and preserve quality of life as much as possible. Treatment approaches generally include areas such as surgery, medical oncology (drug treatments), and radiation oncology (radiation therapy), and these methods are often used together.

Surgical Treatment

Surgery is the cornerstone in the treatment of many uro-oncological cancers. The aim is to remove the entire tumor or the affected organ.

• Radical Prostatectomy: In prostate cancer treatment, it is the surgical removal of the prostate gland and some surrounding tissues. It can be performed with robotic surgery, laparoscopic surgery, or open surgery techniques. Robotic surgery may accelerate the recovery process and reduce side effects by providing more precise movements and smaller incisions.
• Nephrectomy: In kidney cancer treatment, it is the partial (partial nephrectomy) or complete (radical nephrectomy) removal of the kidney. Partial nephrectomy may be preferred to preserve kidney function. Robotic or laparoscopic methods are frequently used.
• Radical Cystectomy: In advanced-stage bladder cancer, it is the complete removal of the bladder. In men, the prostate and seminal vesicles, and in women, the uterus, ovaries, and part of the vagina may also be removed. A new route is created for urine to be expelled from the body (urinary diversion), such as ileal conduit or neobladder.
• Orchiectomy: In testicular cancer treatment, it is the surgical removal of the affected testis.
• Lymph Node Dissection: Surgical removal of lymph nodes to which cancer cells may have spread. It is commonly applied in prostate, bladder, and testicular cancers.
• Penectomy: In penile cancer treatment, it is the removal of part or all of the penis.

Medical Oncology (Drug Treatments)

Drug treatments are used to destroy cancer cells or stop their growth.

• Chemotherapy: Powerful drugs used to kill cancer cells. It may be systemic (affecting the whole body) or local (applied to a specific area). It is commonly used in bladder, testicular, and advanced-stage prostate cancers.
• Hormone Therapy (Anti-Androgen Therapy): It aims to block or reduce the production of male hormones (androgens) that prostate cancer cells need to grow. It plays an important role in the treatment of prostate cancer.
• Targeted Therapies: Drugs that target specific molecules cancer cells need to grow and spread. They are used in kidney cancer and some types of prostate cancer. These treatments may reduce side effects by causing less damage to normal cells.
• Immunotherapy: Treatments that stimulate the body’s own immune system to fight cancer cells. It has shown promising results in the treatment of kidney cancer and bladder cancer.

Radiation Oncology (Radiation Therapy)

Radiotherapy aims to kill or damage cancer cells using high-energy rays.

• External Radiotherapy: Radiation is sent to the cancerous area from outside the body through treatment devices. It is used in prostate cancer, bladder cancer, and sometimes kidney cancer treatment.
• Brachytherapy (Internal Radiotherapy): It is the placement of small radiation-emitting sources directly into or near the tumor. In prostate cancer treatment, especially in low- and intermediate-risk patients, it can be used alone or together with external radiotherapy.

Multidisciplinary Approach and Personalized Treatment

The most effective treatment in uro-oncology is generally planned and applied by a team where different specialties come together. A personalized treatment plan is created by taking into account many factors such as the patient’s condition, cancer characteristics, and the patient’s lifestyle. For example, for a patient with early-stage prostate cancer, active surveillance, surgery, radiotherapy, or brachytherapy options are discussed and the most appropriate method is determined.

Preserving the patient’s quality of life throughout the treatment process is also of great importance. Side effects such as urinary incontinence, sexual dysfunctions, and fatigue are closely monitored and managed by the uro-oncology team. Rehabilitation programs, nutritional counseling, and psychological support are also an integral part of the treatment process.

Who Is a Uro-Oncology Specialist?

A uro-oncology specialist is essentially a doctor who has received specialty training in urology and then gained additional training or experience in cancer biology, medical oncology, radiation oncology, and advanced surgical techniques. These specialists have in-depth knowledge and skills in the diagnosis, treatment, and follow-up of cancers affecting the male reproductive organs (penis, testis, prostate) and the kidneys, ureters (urinary canals), and bladder in both men and women.

Duties of a Uro-Oncology Specialist

The duties of a uro-oncology specialist are quite diverse and cover every stage of the patient’s journey:

1. Making a Diagnosis: Listens to the patient’s complaints, performs a detailed physical examination, and detects urogenital system cancers or suspicious conditions using diagnostic tools such as blood tests, urine tests, imaging methods (ultrasound, CT, MRI), and biopsy.
2. Staging: Determines the stage of the disease by using various tests (imaging, lymph node biopsy, etc.) to determine how far the cancer has spread. This is a critical step in creating the treatment plan.
3. Treatment Planning: Determines the most appropriate treatment strategy by considering the patient’s cancer type, stage, cell grade (aggressiveness), age, general health condition, and personal preferences. This plan may generally include surgery, chemotherapy, radiotherapy, hormone therapy, or targeted therapies and is often created together with a multidisciplinary team.
4. Performing Surgery: Applies advanced surgical techniques such as open, laparoscopic, or robotic surgery to remove cancerous tissues or tumors in organs such as the prostate, kidney, bladder, and testis.
5. Managing Drug Treatments: Applies and follows medical oncological treatments such as chemotherapy, hormone therapy, and targeted therapies. Manages possible side effects during this process.
6. Coordinating Radiotherapy: In close cooperation with radiation oncologists, ensures that the patient receives radiotherapy and monitors the effectiveness and safety of this treatment.
7. Follow-Up and Monitoring: Regularly checks patients after treatment and follows them in terms of recurrence (return of the disease) or treatment-related complications. This follow-up usually includes physical examination, blood tests (e.g. PSA), and imaging methods.
8. Rehabilitation and Side Effect Management: Plans rehabilitation processes to manage side effects that may occur after treatment, such as urinary incontinence and sexual dysfunctions, and to improve the patient’s quality of life.
9. Patient and Family Counseling: Informs patients and their families about the nature of the disease, treatment options, potential risks and benefits, supports them, and guides them in treatment decisions.
10. Following Current Information: Since the field of uro-oncology is constantly developing, specialists must closely follow the latest research, treatment guidelines, and technological innovations.
