GreenLight™ Laser Therapy for Enlarged Prostate (BPH)
GreenLight Laser Therapy is a minimally invasive treatment option for men with benign prostatic hyperplasia (BPH). This advanced laser treatment uses high-powered laser energy to vaporize overgrown prostate tissue that is restricting urine flow. The procedure is performed through the urethra, meaning there are no incisions.
The goal is to open the urinary channel, allowing urine to flow more freely and reducing common BPH symptoms.

Before Treatment
Before treatment begins, you may be asked to empty your bladder.
During Treatment
GreenLight Laser Therapy is typically performed under anesthesia. Once the anesthesia takes effect, your doctor will insert a small scope into your urethra. The scope allows your doctor to see the inner surfaces of the urethra, prostate and bladder.
After the scope is in place, your doctor will advance the laser device through the scope to the location of the enlarged prostate tissue.
Your doctor will then vaporize the prostate tissue that is obstructing urine flow. Dead tissue that is not immediately vaporized will be passed naturally in your urine during the first few days after your surgery.
A temporary urinary catheter may be placed at the end of the procedure to let urine drain from your bladder.
After Treatment & Recovery
- Most patients go home within a few hours after the procedure.
- A catheter may be used temporarily
- Many men experience symptom relief within days to weeks
- Normal activities can often be resumed relatively quickly



Common Questions
Do I have to stay in the hospital after a GreenLight™ procedure?
GreenLight Laser Therapy is generally performed as a same-day surgical procedure. Typically, an overnight stay in the hospital is not required.
What effect does the GreenLight procedure have on sexual function?
In a recent study, 86% of patients reported improved or unchanged sexual satisfaction; 14% worsened. Similar outcomes were seen for erectile function.
How long does it take until symptoms are relieved?
Most patients experience very rapid relief of symptoms and improvement in urine flow within 24 hours of the procedure. However, medical history, health conditions, and other factors can influence treatment and recovery.
Will I continue to need prostate medication after the GreenLight procedure?
Most patients are able to discontinue taking their prostate medication within a few weeks after the GreenLight procedure. However, as with any medication, consult with your doctor before making any changes to your dosing.
How soon can I return to work?
Most patients can resume their normal activities within a couple of days. Strenuous activities can be resumed within a short time. Your doctor will discuss any restrictions and your specific condition with you during your visit following your procedure.
Is GreenLight Laser Therapy covered by insurance?
Yes, GreenLight Laser Therapy is covered by Medicare and most private insurers.
Boston Scientific does not guarantee insurance coverage for any procedure or product. It is the responsibility of the patient to contact their insurance provider for specific coverage information.
What are the risks of GreenLight Laser Therapy?
The most common risks include:
- Hematuria: Blood in the urine
- Irritation of the bladder: Results in frequent and/or urgent need to urinate
- Irritation of the urethra: Frequent urination, burning sensation
- Retrograde ejaculation: Semen during sexual climax travels backward to the bladder rather than exiting through the penis
At doctor’s instruction, some patients taking blood-thinners can be treated with GreenLight Laser Therapy without stopping their medicines.
