BPH Treatment Options: Medications and Procedures

What is BPH and what symptoms does it cause?

BPH is the non-cancerous growth of the prostate gland that occurs as men age. The prostate surrounds the urethra, so when it enlarges, it can constrict urine flow and create a cluster of lower urinary tract symptoms (LUTS):

• Weak or slow urine stream
• Hesitancy — difficulty starting urination
• Incomplete emptying — the feeling that the bladder has not fully emptied
• Frequency — needing to urinate more often, especially at night (nocturia)
• Urgency — sudden, strong urges to urinate
• Dribbling after urination

Symptom severity varies considerably. Some men have measurable prostate enlargement with minimal symptoms; others have significant bother from urinary symptoms without extreme enlargement. Treatment decisions are guided more by how much symptoms affect daily life than by prostate size alone. 1Ref 1Lerner LB, McVary KT, Barry MJ, et al. (2021).Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA Guideline Part I — Initial Work-up and Medical Management.First-line and combination medical management of BPH/LUTS, including alpha blockers, 5-ARIs, PDE5 inhibitors, and indication thresholds

What lifestyle changes help with BPH symptoms?

For mild symptoms, behavioral and lifestyle modifications are often recommended as a first step:

• Reducing fluid intake in the evening to reduce nighttime urination
• Limiting caffeine and alcohol, which can increase urinary urgency
• Timed voiding — urinating on a schedule rather than waiting for urgency
• Double voiding — urinating, waiting a moment, then trying again to more fully empty the bladder
• Managing constipation, which can worsen urinary symptoms
• Reviewing medications — some antihistamines, decongestants, and antidepressants can worsen urinary retention

These measures do not reverse the underlying prostate growth but can meaningfully reduce the symptom burden for men with mild to moderate BPH.

What medications are used for BPH?

When lifestyle changes are not sufficient, medication is typically the next step. [1, 2]

Alpha blockers (e.g., tamsulosin, alfuzosin, silodosin, terazosin, doxazosin) are usually the first-line medication. They relax the smooth muscle in the prostate and bladder neck, reducing urinary resistance. They work relatively quickly — often within days to a few weeks — and are effective at improving flow and reducing symptoms. Side effects can include dizziness, low blood pressure (particularly with position changes), and retrograde ejaculation.

5-alpha reductase inhibitors (5-ARIs) (e.g., finasteride, dutasteride) work differently: they reduce the actual size of the prostate by blocking the hormone (DHT) that drives prostate growth. They take 6–12 months to show full effect and are most useful in men with significantly enlarged prostates. They can reduce the risk of acute urinary retention and the need for future surgery. Side effects include decreased libido and erectile dysfunction in some men. Notably, 5-ARIs lower PSA levels, which must be accounted for in prostate cancer screening.

Combination therapy — an alpha blocker plus a 5-ARI — is appropriate for men with larger prostates and more significant symptoms, and has been shown to be more effective than either agent alone for preventing disease progression.

Phosphodiesterase-5 inhibitors (e.g., tadalafil) are also approved for BPH symptoms and can be a good option for men who also have erectile dysfunction. 1Ref 1Lerner LB, McVary KT, Barry MJ, et al. (2021).Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA Guideline Part I — Initial Work-up and Medical Management.First-line and combination medical management of BPH/LUTS, including alpha blockers, 5-ARIs, PDE5 inhibitors, and indication thresholds

Anticholinergics or beta-3 agonists are sometimes added if urgency and frequency symptoms persist despite other treatment, but require care in men with poor bladder emptying.

No herbal supplement (including saw palmetto) has demonstrated reliable efficacy in rigorous clinical trials for BPH.

What minimally invasive procedures are available for BPH?

For men with moderate to severe symptoms who have not responded adequately to medication, or who prefer to avoid long-term medications, minimally invasive procedures offer an intermediate option between pills and surgery. 2Ref 2Lerner LB, McVary KT, Barry MJ, Bixler BR, Dahm P, Das AK, Gandhi MC, Kaplan SA, Kohler TS, Martin L, Parsons JK, Roehrborn CG, Stoffel JT, Welliver C, Wilt TJ (2021).Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA GUIDELINE PART II-Surgical Evaluation and Treatment.Surgical and minimally invasive procedural options for BPH including TURP, laser procedures, UroLift, and Rezum

• UroLift (prostatic urethral lift) — small implants hold the enlarged prostate lobes apart, opening the urethral channel without cutting or heating tissue. Suitable for men who wish to preserve ejaculatory function
• Rezum (water vapor therapy) — steam is injected into the prostate to destroy excess tissue. A minimally invasive in-office procedure
• Transurethral microwave therapy (TUMT) — uses microwave energy to reduce prostate tissue
• Transurethral needle ablation (TUNA) — uses radiofrequency energy delivered through needles into the prostate

These procedures are generally performed in a urology office or outpatient setting under local anesthesia or light sedation.

When is surgery needed for BPH?

Surgical options are appropriate for men with severe symptoms, large prostates, or complications such as recurrent urinary tract infections, bladder stones, kidney damage from obstruction, or inability to urinate (urinary retention). 2Ref 2Lerner LB, McVary KT, Barry MJ, Bixler BR, Dahm P, Das AK, Gandhi MC, Kaplan SA, Kohler TS, Martin L, Parsons JK, Roehrborn CG, Stoffel JT, Welliver C, Wilt TJ (2021).Management of Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: AUA GUIDELINE PART II-Surgical Evaluation and Treatment.Surgical and minimally invasive procedural options for BPH including TURP, laser procedures, UroLift, and Rezum

• TURP (transurethral resection of the prostate) — the traditional surgical standard, performed through the urethra with a resecting loop. Highly effective, with a long track record
• Laser procedures (HoLEP — holmium laser enucleation of the prostate; GreenLight laser vaporization) — effective alternatives with less bleeding, sometimes better suited for very large prostates or men on anticoagulants
• Simple prostatectomy — open or robotic-assisted surgical removal of the inner portion of the prostate, reserved for the largest glands

A urologist can discuss the trade-offs, expected outcomes, and risks of each approach based on prostate size, anatomy, and personal priorities. Gale can help you find a urologist and prepare the right questions for your visit.
