When Does an Enlarged Prostate Require Treatment?
In brief
An enlarged prostate (BPH) needs treatment when its symptoms bother you or affect your quality of life, or when it causes complications such as urinary retention, recurrent infections, bladder stones or kidney problems. Mild, non-bothersome symptoms can often be safely monitored.

Can an enlarged prostate just be monitored?
Yes, often. Prostate size alone is not a reason for treatment. If symptoms are mild and not bothersome, watchful waiting with simple lifestyle measures — reducing evening fluids, caffeine and alcohol, and reviewing medicines that affect urination — is a reasonable approach, with periodic review.
What signs mean treatment should be considered?
- Symptoms that disturb your sleep, work, travel or social life
- Getting up several times each night to urinate
- A feeling that the bladder never empties, or a large amount of urine left after voiding
- Recurrent urinary infections or blood in the urine
- Bladder stones
- Rising creatinine or swelling of the kidneys on a scan, caused by obstruction
Seek emergency care if you suddenly cannot pass urine
Acute urinary retention is painful and needs prompt catheter drainage.
What are the treatment options?
- Lifestyle measures and bladder training
- Medication — alpha-blockers (such as tamsulosin) relax the prostate; 5-alpha reductase inhibitors (finasteride, dutasteride) shrink larger prostates over months
- Minimally invasive procedures — Rezūm and UroLift
- Surgery — TURP, laser procedures or, for very large prostates, simple prostatectomy
Procedures are often considered when medication does not help enough, causes side effects, or a man would prefer not to take tablets long term. See the prostate treatments overview.
What tests help decide?
A urologist will typically use a symptom questionnaire, urine test, measurement of urine flow and bladder emptying, and a prostate ultrasound. A PSA test may be discussed — see Understanding your PSA test.
Frequently asked questions
Will an enlarged prostate keep getting worse?
Not always. Symptoms may stay stable for years, improve, or worsen. Regular review helps identify men whose symptoms or complications are progressing.
