Benign Prostatic Hyperplasia (BPH) refers to the noncancerous enlargement of the prostate gland, a walnut-sized gland located below the bladder in men. As the prostate grows in size, it can squeeze the urethra, causing urinary symptoms and potentially affecting bladder function.
Prevalence and Impact on Men’s Health
BPH is common in older men, with over 50% of men in their 60s and up to 90% in their 70s and 80s experiencing symptoms. BPH can significantly impact quality of life, leading to bothersome urinary symptoms and potential complications if untreated.
Causes and Risk Factors
Age-related Hormonal Changes
With age, men experience hormonal shifts, including an increase in estrogen levels and a decrease in testosterone. These changes can disrupt the hormonal balance, leading to the enlargement of the prostate gland, a common characteristic of BPH.
Genetic Predisposition
Research indicates a genetic link in the development of BPH. Men with a family history of BPH, particularly among close relatives like fathers or brothers, are at a heightened risk of developing the condition.
Lifestyle Factors
Certain lifestyle factors can contribute to the risk of developing BPH. These include:
- Obesity: Being overweight or obese increases the risk of BPH.
- Sedentary lifestyle: Lack of physical activity may be associated with a higher likelihood of developing BPH.
- Diet: A diet high in red meat and low in fruits and vegetables may increase the risk of BPH.
Medical Conditions that May Contribute to BPH
Certain medical conditions can contribute to the development or exacerbation of BPH, including:
- Diabetes: Diabetes can contribute to BPH due to insulin resistance stimulating prostate cell growth. Additionally, diabetes-related nerve damage can worsen BPH urinary symptoms.
- Heart disease: Heart disease and BPH share common risk factors like age and obesity. Beta-blockers, used in heart disease management, can cause urinary symptoms similar to BPH.
- Metabolic syndrome: Metabolic Syndrome is a cluster of conditions that occur together, increasing your risk of heart disease, stroke, and type 2 diabetes. Conditions include high blood pressure, high blood sugar, and abnormal cholesterol levels, which can lead to hormonal imbalances contributing to prostate enlargement, key characteristic of BPH.
- Family History of BPH: Genetics can play a role in the development of BPH. If close male relatives, such as your father or brother, have BPH, your chances of developing the condition may be higher.

Symptoms and Complications of BPH
Urinary Symptoms Associated with BPH
Common urinary symptoms associated with BPH may include:
- Frequent urination: This is often the first noticeable symptom of BPH. As the prostate enlarges, presses against the urethra, causing a need to urinate more often than usual, especially at night (nocturia).
- Difficulty Starting Urination: Men with BPH may find it hard to start urinating. This is due to the increased pressure on the urethra, which can make it difficult for urine to flow freely.
- Weak Urine Stream or Dribbling: BPH can cause a weak or interrupted urine stream. Some men may also experience dribbling at the end of urination.
- Inability to Completely Empty the Bladder: As BPH progresses, it may become difficult to fully empty the bladder.
- Urgency to Urinate: Men with BPH may feel a sudden, strong urge to urinate, which can be difficult to control.
Potential Complications if BPH is Left Untreated
If BPH is left untreated, it can lead to several complications. These include:
- Urinary Tract Infections (UTIs): Incomplete bladder emptying can lead to urinary stasis, which increases the risk of UTIs.
- Bladder Stones: These are hard deposits of minerals that can form when the bladder isn’t completely emptied. They can cause pain and lead to UTIs.
- Bladder Damage: Chronic retention of urine can lead to bladder damage over time, affecting its ability to contract and fully empty.
- Kidney Damage: In severe cases, BPH can cause backflow of urine into the kidneys, a condition known as hydronephrosis. This can lead to kidney damage if not treated promptly.
Diagnosing Benign Prostatic Hyperplasia (BPH)
Medical History and Physical Examination
The urologist will take a detailed medical history and conduct a physical examination, including a digital rectal examination (DRE), to assess the size and condition of the prostate gland.
Urine and Blood Tests
Urine tests may be conducted to check for any signs of infection or blood in the urine. Blood tests, including prostate-specific antigen (PSA) levels, may be performed to help rule out prostate cancer and evaluate overall prostate health.
Prostate-specific Antigen (PSA) Testing
PSA testing measures the levels of PSA, a protein produced by the prostate gland, in the blood. Elevated PSA levels can indicate various prostate conditions, including BPH and prostate cancer. However, many factors can affect PSA levels, so this test is usually considered alongside other diagnostic information.
Imaging Studies and Other Diagnostic Procedures
Imaging studies, such as ultrasound or MRI, may be conducted to assess the size and structure of the prostate gland. In some cases, additional diagnostic procedures, such as urodynamic testing or cystoscopy, may be recommended to evaluate bladder function and rule out other urinary conditions.
Treatment Options
Watchful Waiting and Lifestyle Modifications
For individuals with mild symptoms, the urologist may recommend a watchful waiting approach, where regular monitoring is conducted without immediate intervention. Lifestyle modifications, such as reducing fluid intake before bedtime and avoiding caffeine and alcohol, can also help manage symptoms.
Medications for Symptom Relief
Medications can be prescribed to alleviate BPH symptoms. These may include:
- Alpha-blockers: Relax the muscles around the prostate and bladder neck to improve urine flow.
- 5-alpha reductase inhibitors: Reduce the size of the prostate gland by inhibiting the production of certain hormones.
- Combination therapy: A combination of alpha-blockers and 5-alpha reductase inhibitors may be used for more significant symptom relief.
Minimally Invasive Procedures
This procedure aims to relieve urinary symptoms by reducing prostate gland size or removing excess prostate tissue. Examples include:
- Transurethral Microwave Thermotherapy (TUMT): Microwaves are used to shrink the prostate and relieve urinary symptoms.
- Transurethral Needle Ablation (TUNA): Needles deliver low-level radiofrequency energy to destroy excess prostate tissue, reducing its size and improving urinary flow.
- Water-induced Thermotherapy (WIT): Heated water is circulated to shrink the prostate tissue and alleviate urinary symptoms.
- Prostatic Urethral Lift (PUL): Small implants are placed in the prostate to lift and hold the enlarged tissue away from the urethra, improving urine flow.
Surgical Interventions
In cases of severe BPH or when other treatments have not provided sufficient relief, surgical interventions may be considered. Common surgical procedures for BPH include:
- Transurethral Resection of the Prostate (TURP): TURP is a surgery where a special instrument is inserted through the urethra to remove excess prostate tissue, improving urine flow.
- Laser Surgery: Laser surgery uses laser energy to vaporize or remove the excess prostate tissue, reducing its size and improving urinary symptoms.
- Open Prostatectomy: Open prostatectomy is a traditional surgery that involves making an incision in the lower abdomen to remove the enlarged part of the prostate, alleviating urinary symptoms.
Conclusion
Benign Prostatic Hyperplasia (BPH) is a common condition affecting many men, particularly as they age.
If you are experiencing urinary symptoms, seek medical advice from a urologist. Early detection and treatment of BPH can significantly improve your quality of life and prevent potential complications.
Types Of Bladder Cancer | What You Need To Know
Bladder cancer refers to any malignant growth that originates in the bladder. The cancer begins in the cells lining the inside of the bladder, known as urothelial cells. The cancer cells can proliferate, forming a tumour and possibly spreading to other parts of the body.
Types of Bladder Cancer
Bladder cancer is typically classified into several types, largely dependent on the cells in which it originates. Each type demonstrates unique characteristics, affecting the treatment approach and overall prognosis.
- Transitional Cell Carcinoma (Urothelial Carcinoma): Transitional Cell Carcinoma is the most common type, making up about 90% of all bladder cancers. It starts in the urothelial cells, the innermost lining of the bladder. These cells can stretch when the bladder is full and shrink when it is emptied. This cancer can be non-muscle invasive, where it’s limited to the inner layer of the bladder, or muscle-invasive, where it has spread to the bladder’s muscular wall.
- Squamous Cell Carcinoma: Squamous cells are flat, thin cells that can form in the bladder as a response to long-term infection or irritation, accounting for about 1-2% of all bladder cancers. Squamous cell carcinoma arises when these cells become malignant over time due to prolonged infection or irritation. This form of bladder cancer is more common in regions where parasitic infections in the bladder are common. These infections can lead to chronic bladder inflammation, promoting squamous cell transformation and eventually, carcinoma.
- Adenocarcinoma: Adenocarcinoma is a rare type of bladder cancer, contributing to less than 1% of all cases. It originates in the glandular (secretory) cells located in the bladder lining, which produce and release mucus. This type of cancer may develop from prolonged inflammation and irritation, or from a congenital condition known as exstrophy that affects bladder development. Adenocarcinoma of the bladder often presents a challenge in treatment, owing to its typical discovery at advanced stages.
Understanding the different types of bladder cancer impacts both treatment options and outcomes. A urologist will be able to provide guidance based on the specific type and stage of bladder cancer diagnosed.

Non-Muscle Invasive and Muscle Invasive Bladder Cancers
Bladder cancer can be broadly categorised into two main types: Muscle Invasive Bladder Cancer (MIBC) and Non-Muscle Invasive Bladder Cancer (NMIBC). Each type has distinct characteristics, treatment approaches, and prognostic factors.
Muscle Invasive Bladder Cancer (MIBC)
MIBC is a type of bladder cancer where the abnormal cells have infiltrated the muscle layer of the bladder. MIBC is more aggressive and has a higher potential to spread to other parts of the body compared to NMIBC.
Key points about MIBC:
Subtypes of MIBC: The most common subtype of MIBC is urothelial carcinoma, which arises from the transitional cells lining the bladder. Other less common subtypes include squamous cell carcinoma and adenocarcinoma.
Diagnosis and Staging of MIBC: The diagnosis of MIBC involves various tests and procedures. Imaging tests, such as CT scans and MRIs, help evaluate the extent of tumour infiltration. A biopsy of the bladder tissue confirms the presence of cancer cells. Staging systems, such as the TNM classification, are used to determine the stage of MIBC and guide treatment decisions.
Non-Muscle Invasive Bladder Cancer (NMIBC)
NMIBC is a type of bladder cancer where the abnormal cells are confined to the innermost lining of the bladder and have not invaded the muscle layer. NMIBC is considered less aggressive and has a lower risk of spreading beyond the bladder.
Key points about NMIBC:
Subtypes of NMIBC: NMIBC includes several subtypes, the most common of which are papillary tumours and carcinoma in situ (CIS). Papillary tumours grow as projections from the bladder lining, while CIS refers to the presence of flat, high-grade cancer cells.
Diagnosis and Staging of NMIBC: The diagnosis of NMIBC involves various diagnostic procedures, such as urine tests (cytology, NMP22, FISH) to detect abnormal cells shed in the urine. Cystoscopy, a procedure where a thin tube with a camera is inserted into the bladder, allows visual examination of the bladder lining. Biopsy samples may be taken during cystoscopy to confirm the presence of cancer cells. Staging systems, such as the TNM classification, help determine the stage and extent of NMIBC.
Conclusion
Increasing awareness and knowledge about these distinct types of bladder cancer can help individuals make informed decisions regarding prevention, early detection, and appropriate treatment strategies.
Bladder Cancer: A Urologist’s Guide To Treatments
Bladder cancer is a common type of cancer that begins in the cells of the bladder, a hollow organ in the lower abdomen that stores urine. It is often detected early when it is highly treatable, but it has a high recurrence rate.
Treatment Options
The choice of treatment depends on various factors, including the type and stage of the cancer, the patient’s overall health, and personal preferences.
Surgery: Surgery is often the first step in treating bladder cancer. The kind of surgery depends on how much the cancer has spread.
- Transurethral bladder tumour resection (TURBT): Used for early-stage bladder cancer. A thin tube with a camera on the end is inserted through the tube where urine exits the body (urethra) into the bladder. A special tool is used to remove the tumour or burn it away. This is done under anaesthesia and the patient doesn’t feel pain.
- Radical cystectomy: This surgery is used when the cancer has spread more deeply into the bladder. The entire bladder and possibly other nearby organs that might contain cancer cells is removed. For men, this might include the prostate, and for women, it might include the uterus and ovaries. The lymph nodes in the area might also be removed to check for cancer spread.
- Partial cystectomy: Only the part of the bladder that contains cancer cells is removed. This is usually done when the cancer is in a specific area that can be easily removed. The rest of the bladder is left intact to store urine.
- Urinary diversion: If the entire bladder is removed, the body needs a new way to store and get rid of urine. This is called urinary diversion. There are several methods, including:
- a method where urine flows into a bag outside of the body,
- a method where urine is stored inside the body and drained through a tube, and
- a method where a pouch is attached to the urethra to allow for more normal urination.

Chemotherapy: Uses drugs to kill cancer cells or to stop them from dividing.
- Neoadjuvant chemotherapy: This is chemotherapy given before surgery. The goal is to shrink the cancer, making it easier to remove during surgery. It can also kill any tiny bits of cancer that may have spread but are too small to see.
- Adjuvant chemotherapy: This is chemotherapy given after surgery. The goal is to kill any cancer cells that might have been left behind. It can also help to stop the cancer from coming back.
There are two ways to give chemotherapy for bladder cancer:
- Intravesical chemotherapy: The medicines are put directly into the bladder through a tube. This mainly affects the cells in the bladder and usually has fewer side effects.
- Systemic chemotherapy: The medicines are given by injection into a vein or taken as a pill. They then travel through the body to kill cancer cells wherever they are. This can have more side effects, but it can also be more effective if the cancer has spread.
Immunotherapy: Stimulates the body’s immune system to fight cancer.
- Bacillus Calmette-Guérin (BCG) therapy: In BCG therapy, a weakened version of BCG bacteria is put directly into the bladder through a tube. BCG therapy is often used for early-stage bladder cancer and is good at stopping the cancer from coming back after surgery. BCG therapy is usually given once a week for six weeks, and then less often for up to a year. It’s a local treatment, which means it only affects the bladder and doesn’t have the same side effects as treatments like chemotherapy. But it can still cause side effects, like bladder irritation and flu-like symptoms.
Targeted Therapy: In targeted therapy, drugs block specific genes or proteins that promote cancer cell growth and survival. It’s commonly used for advanced or metastatic bladder cancer. These drugs, usually taken as pills, slow down cancer cell growth and can shrink tumours. Targeted therapy isn’t suitable for all bladder cancer patients. The decision to use it depends on factors like genetic changes in the tumour, cancer stage, and overall health.
Gene Therapy: Gene therapy is an innovative approach to treat cancer by modifying the genes inside a person’s cells. In gene therapy for bladder cancer, the genes in bladder cells are altered to slow down or prevent the growth of cancer cells. This can involve introducing new genes that produce proteins to fight cancer or deactivating genes that promote cancer growth. Gene therapy for bladder cancer is still being studied in clinical trials and is not widely available as a standard treatment.
Radiation Therapy: Uses high-energy radiation to kill cancer cells. It’s often used instead of surgery or after surgery to eliminate remaining cancer cells. This damages the DNA in cancer cells, stopping them from growing and causing them to die. It can be used as an alternative to surgery or after surgery to remove any remaining cancer cells. Radiation therapy is delivered over several weeks, with short and painless sessions. Side effects may include fatigue, skin changes, and urinary issues.
Conclusion
Bladder cancer has various treatment options based on the cancer’s stage, patient’s health, and personal preferences. Each treatment has its specific use, from removing tumours and killing cancer cells to stimulating the immune system or blocking cancer growth.
Preparing For A Vasectomy | A Urologist’s Guide
Undergoing vasectomy requires adequate preparation and understanding to help you make an informed decision about your health.
Understanding Vasectomy
A vasectomy is a surgical procedure, typically performed by a urologist, which serves as a form of male sterilisation. It involves cutting or sealing the vas deferens, the tubes that carry sperm from the testicles to the urethra.
The urologist first numbs the scrotum during a vasectomy with a local anaesthetic. A small incision or puncture hole is made on one side of the scrotum to access the vas deferens. The tubes are cut, tied, or otherwise sealed to prevent sperm transportation.
The exact process is repeated on the other side of the scrotum. This procedure prevents sperm from reaching the semen ejaculated from the penis, making it a highly effective form of birth control.
This outpatient procedure typically takes about 20 to 30 minutes.
Evaluating Personal Suitability for Vasectomy
Before deciding on a vasectomy, consider several factors:
- Existing Medical Conditions: Certain conditions, such as blood disorders, infections, or cancers, may affect the eligibility for a vasectomy. Urologists evaluate patients on a case-by-case basis.
- Personal and Family Medical History: Discussions with your urologist should include your medical history and that of your family. Factors such as allergies, past surgeries, or inherited conditions can influence decision-making.
- Future Family Planning: Consider vasectomy as an irreversible procedure. While reversal surgeries are possible, it doesn’t always guarantee success.
Pre-Vasectomy Consultation
The pre-vasectomy consultation allows the patient and urologist to discuss the procedure in detail. The consultation will typically involve:
- Medical Examination: A physical examination, possibly including a testicular ultrasound, to assess overall suitability for the procedure.
- Discussion of Medical History: An opportunity to discuss any medical conditions, medications currently taken, and any previous surgeries.
- Procedure Explanation: The urologist will explain the procedure in detail, including potential risks and complications.
Key questions to ask your urologist during this consultation may include:
- What is the preferred technique for my vasectomy?
- What are the possible short and long-term complications?
- What can I expect during recovery?

For Your Condition
Physical Preparation
The following are general health and lifestyle factors that can impact the procedure and recovery process:
- Smoking: Smoking can delay healing, so stop it before the procedure
- Alcohol: Alcohol can thin the blood, increasing the risk of bleeding. Limit alcohol intake before the procedure.
- Medication: Some medications, such as blood thinners, can affect bleeding. Discuss all medications with your urologist.
Specific dietary and physical activity guidelines include:
- Eat a light meal before the procedure.
- Shower with antibacterial soap on the day of the surgery.
- Refrain from heavy physical activity in the days before and after the procedure.
Mental and Emotional Preparation
Vasectomy can have emotional implications. It’s normal to experience anxiety or concerns. Manage these feelings by:
- Counselling: Speaking with a professional counsellor can help manage concerns.
- Relaxation Techniques: Techniques such as deep breathing or meditation can reduce anxiety.
Post-Procedure Recovery
The typical recovery time for a vasectomy is usually between a few days to a week. Do the following to help with recovery:
- Rest: Ensure you get plenty of rest post-procedure. Rest for 24-48 hours following a vasectomy, avoiding strenuous activities.
- Ice Packs: Applying ice packs to the scrotum can reduce swelling and alleviate discomfort. Typically, ice packs are recommended for 10-20 minutes at a time, every 1-2 hours, for the first 24 hours post-procedure.
- Supportive Underwear: Snug-fitting underwear or a jockstrap can support the scrotum post-vasectomy. This can reduce movement and potential discomfort, aiding in healing.
- Pain Management: Over-the-counter pain medication, such as paracetamol, can be used to manage pain. Always follow the dosage instructions provided.
- Hygiene: While you should keep the area clean, avoid baths and prefer showers for the first few days post-vasectomy. Also, dry the area to prevent potential infections gently.
- Monitor for Complications: If you notice extreme swelling, bleeding, or signs of infection (like redness, warmth, or a foul odour), contact your urologist immediately.
A vasectomy doesn’t affect testosterone levels, sexual function, or libido. Any changes in sexual function are typically due to psychological factors rather than the procedure itself.
Resumption of sexual activity is possible within a week of the procedure but continue using other forms of birth control until your urologist confirms the absence of sperm in your semen.
Conclusion
Making an informed decision about a vasectomy involves understanding the procedure, assessing personal suitability, and preparing physically and mentally. For personalised advice, consult with a professional urologist.
