What are the standard treatments for prostate enlargement?
An enlarged prostate (benign prostatic hyperplasia, or BPH) can sometimes be associated with lower abdominal pain due to its impact on the urinary system. Here’s how:
Urinary Retention and Bladder Distention: As the prostate enlarges and shuts off the urethra, it is more difficult to fully drain the bladder. This leads to urinary retention, with urine collecting in the bladder. The bladder then becomes distended (stretched) with time, causing lower abdominal discomfort or pain. The more distended the bladder is from retention, the more severe the pain can become.
Increased Bladder Pressure: As the prostate enlarges, the bladder has to work harder to push urine through the compressed urethra. The increased pressure causes pain or a dull ache in the lower abdomen. The pain gets worse when the bladder is full or when one tries to urinate but is not able to completely empty the bladder.
Urinary Tract Infections (UTIs): Incomplete emptying of the bladder and chronic urinary retention can predispose to urinary tract infections. UTIs can lead to pain or a burning sensation in the lower belly, along with other symptoms like urgency, frequent urination, and cloudy urine.
Prostate Inflammation: The inflated prostate in a few men will also become inflamed (prostatitis), which results in pain in the pelvic area or lower abdomen. The pain at times can be a pressure or aching pain.
Straining to Urinate: The straining while urinating due to the obstruction done by the inflated prostate can also result in additional pressure on the lower abdomen, resulting in pain or discomfort.
If one has ongoing lower abdominal pain and is having symptoms of prostate enlargement (like frequent urination, weak urine flow, or trouble urinating), consult a doctor. The pain might be due to complications, like bladder distension, urinary infection, or prostatitis, which might need treatment.

The standard treatments for prostate enlargement include the following:
The treatment of benign prostatic hyperplasia (BPH) or enlarged prostate depends on the severity of the symptoms and how much they interfere with one’s quality of life. The treatments in general are lifestyle modification, medications, and, in some cases, surgery. The overview is as follows:
1. Lifestyle Changes:
Fluid Management: Reducing fluid consumption, especially in the evening before bedtime, can render nocturia (urination at night) less frequent.
Timed Voiding: Voiding at regular intervals, even in the absence of a strong desire to urinate, can manage symptoms.
Avoiding Bladder Irritants: Avoiding caffeine, alcohol, and certain medications that irritate the bladder or exacerbate symptoms.
2. Medications:
Alpha Blockers (i.e., alfuzosin, tamsulosin): These drugs relax the muscles in the prostate and bladder neck, making it easier to urinate. They improve symptoms like urgency, weak stream, and frequent urination.
5-Alpha-Reductase Inhibitors (e.g., finasteride, dutasteride): These medications shrink the prostate gland by blocking the hormone dihydrotestosterone (DHT), which contributes to prostate enlargement. They can improve symptoms over time but may take several months to become effective.
Combination Therapy: Occasionally doctors will prescribe both an alpha blocker and a 5-alpha-reductase inhibitor combination for better symptom relief.
Phosphodiesterase-5 Inhibitors (e.g., tadalafil): These medications, typically used to treat erectile dysfunction, can also treat symptoms of BPH by relaxing prostate muscles and improving urine flow.
3. Minimally Invasive Procedures:
Transurethral Microwave Therapy (TUMT): This treatment uses microwave energy to destroy excess prostate tissue and relieve symptoms. It’s typically done on an outpatient basis and is less invasive than surgery.
Transurethral Needle Ablation (TUNA): This therapy employs radiofrequency energy to shrink the prostate tissue and improve symptoms. It is performed under local anesthesia.
UroLift System: This therapy involves the placement of small devices that lift and hold the enlarged prostate tissue out of the way of the urethra, allowing for improved urine flow. It’s minimally invasive and doesn’t cut or remove prostate tissue.
Laser Therapy (e.g., Holmium Laser Enucleation of the Prostate, GreenLight Laser): Laser therapy has the ability to vaporize or cut away excess prostate tissue, offering a less invasive option compared to traditional surgery.
4. Surgical Treatments:
Transurethral Resection of the Prostate (TURP): This is the most common surgical procedure for the treatment of BPH. It involves the surgical removal of excess prostate tissue using a resectoscope, which is inserted via the urethra. The operation is highly effective in relieving symptoms but may have complications like bleeding and sexual side effects.
Simple Prostatectomy: For very enlarged prostates, a simple prostatectomy may be performed, where a part of the prostate is surgically removed via an incision in the abdomen. This is generally reserved for when other treatments fail or the prostate is too large to be managed with less invasive methods.
Prostatic Artery Embolization (PAE): This is a newer, less invasive procedure where the blood supply to the prostate is blocked to reduce it in size. It’s usually kept for men who are not candidates for surgery.
5. Watchful Waiting:
For mild symptoms that are not significantly affecting quality of life, doctors may recommend “watchful waiting,” where the patient is monitored for a period and only treated if symptoms worsen. Lifestyle changes and medications may still be used to manage symptoms in the meantime.
6. Alternative and Complementary Therapies:
Herbal Supplements: Some men use herbal supplements, such as saw palmetto or beta-sitosterol, to ease symptoms of BPH, but it is uncertain how well these treatments work, and they need to be used cautiously.
Acupuncture: Some studies suggest that acupuncture can ease symptoms of BPH, but more research is needed to find out how well it works.
Treatment is typically chosen based on the severity of the symptoms, the size of the prostate, the patient’s overall health, and personal preferences. If you are experiencing symptoms of BPH, it’s important to consult with a healthcare provider to determine the best course of action for your individual situation.
Alpha-blockers are a class of medications that are commonly used to alleviate the symptoms of benign prostatic hyperplasia (BPH) or enlarged prostate. They work by blocking the alpha-adrenergic receptors in the prostate’s smooth muscle and the bladder neck, which leads to improved urinary flow and a reduction in urinary obstruction symptoms. The following is how alpha-blockers help in the management of prostate enlargement:
Mechanism of Action:
Relaxation of Prostate and Bladder Neck Muscles:
The prostate and bladder neck (the area where the bladder connects to the urethra) contain smooth muscle that, in an enlarged prostate, can constrict and impede the flow of urine. Alpha-blockers work by blocking alpha-1 adrenergic receptors on the prostate and bladder neck’s smooth muscle.
By relaxing the smooth muscles, alpha-blockers widen the prostate and bladder neck, reducing obstruction and making urine flow more easily from the bladder via the urethra.
Better Urinary Flow:
Relaxation of the smooth muscles enhances urinary flow, relieving symptoms such as hesitancy (difficulty in initiating urination), weak stream, straining, and feeling of incomplete bladder emptying.
This leads to the promotion of urination and the reduction in urgency and frequency that occurs in BPH.
Reduced Bladder Outlet Obstruction:
The relaxation of bladder neck muscles also reduces bladder outlet obstruction, which is a significant determinant of BPH symptoms. This reduces the pressure the bladder has to generate to push the urine through the constricted area, leading to less strain on the bladder and more effective emptying.
Benefits of Alpha-Blockers in BPH:
Symptom Relief:
Alpha-blockers provide relief in the urinary symptoms of BPH, such as difficulty in initiating urination, weak urinary stream, frequent urination (especially nocturia), and the sensation of incomplete bladder emptying.
Rapid Onset of Action:
Alpha-blockers have a rapid action, and the symptoms of urination improve within a few days of starting therapy. This makes them a popular first-line treatment for symptomatic management in BPH.
Non-Surgical Option:
In the majority of men with moderate symptoms of BPH, alpha-blockers can be extremely effective in alleviating symptoms without the need for invasive procedures or surgery.
Commonly Used Alpha-Blockers for Prostate Enlargement:
Tamsulosin (Flomax):
One of the most commonly used alpha-blockers for BPH is tamsulosin. It is selective for the alpha-1A receptors, which are found primarily in the prostate and bladder neck, leading to a more specific action and reduced side effects related to blood pressure.
Alfuzosin (Uroxatral):
Alfuzosin is another alpha-blocker used in the management of BPH. It also works by relaxing the smooth muscle of the prostate and bladder neck, improving urinary flow.
Terazosin (Hytrin) and Doxazosin (Cardura):
These are non-selective alpha-blockers that relax smooth muscles in the prostate and blood vessels. They are therapeutic in BPH but, as they relax blood vessels also, low blood pressure is a side effect, especially on standing up quickly (orthostatic hypotension).
Side Effects of Alpha-Blockers:
Alpha-blockers are well tolerated, but they do cause some side effects, particularly when treatment is initiated. These side effects include:
Dizziness or Lightheadedness:
Alpha-blockers can lead to low blood pressure, especially when rising from the lying or sitting position (orthostatic hypotension), with dizziness or fainting. This is more common with non-selective alpha-blockers (e.g., terazosin and doxazosin).
Fatigue:
Weakness or fatigue can be noted in some people on starting alpha-blockers, especially at high doses.
Retrograde Ejaculation:
Tamsulosin and other alpha-blockers may cause retrograde ejaculation, a condition where semen enters the bladder instead of exiting through the urethra during orgasm. While harmless, this can be frightening to some men.
Headache and Nasal Congestion:
Alpha-blockers may cause minor symptoms like headaches and nasal congestion, though they are typically mild and improve with time.
Sexual Dysfunction:
Occasionally, alpha-blockers can cause sexual side effects, such as difficulty achieving or maintaining an erection, but these are less likely to occur than with medications such as 5-alpha-reductase inhibitors.
Conclusion:
Alpha-blockers are an effective and commonly utilized therapy for the treatment of benign prostatic hyperplasia (BPH) symptoms, particularly for the relief of urinary obstruction and improvement in urine flow. They work by relaxing the smooth muscles of the bladder neck and prostate, reducing the pressure in the urethra and relieving the flow of urine. They have a rapid relief of symptoms and are an ideal option for men who do not want surgery. They can, however, cause side effects, especially those relating to blood pressure, and should therefore be used under the care of a health practitioner.
