For millions of aging men, benign prostatic hyperplasia (BPH)—the non-cancerous enlargement of the prostate gland—silently erodes daily independence. What begins as mild urinary hesitancy or a slow stream often progresses to debilitating symptoms: waking up four or five times a night (nocturia), sudden uncontrollable urgency, or the constant fear of urinary retention.
For years, men caught in the middle of BPH progression faced a difficult choice: rely indefinitely on prescription medications that cause fatigue, dizziness, or sexual dysfunction, or undergo invasive surgical scraping (TURP) that required multi-day hospital stays and carried significant bleeding risks.
At St. Francis Hospital & Heart Center in Roslyn and his nearby office in East Hills (Roslyn), Dr. David Samadi offers a modern, incisionless solution: GreenLight™ Photoselective Vaporization of the Prostate (PVP). By utilizing high-powered laser energy delivered through a microscopic optical fiber, Dr. Samadi vaporizes obstructive prostate tissue in a swift, outpatient procedure—restoring powerful, natural urine flow with virtually zero blood loss.
Understanding the BPH Blockage
The prostate gland sits directly beneath the bladder, encircling the upper urethra like a collar. As men age, hormonal shifts cause the internal central zone (transition zone) of the prostate to expand inward.
[Normal Prostate] ──> Wide open urethral channel ──> Effortless bladder emptying
VS.
[Enlarged BPH] ──> Compressed, narrow urethra ──> Straining, frequency, & incomplete voiding
As the tissue swells, it constricts the urethra, forcing the bladder muscle to work twice as hard to push urine out. Over time, this constant resistance causes the bladder wall to thicken and become hyper-irritable, leading to the severe urgency and nighttime waking that disrupts a man’s quality of life.
How GreenLight™ Laser Vaporization Works
GreenLight™ Laser PVP is an advanced, ultra-minimally invasive procedure performed entirely through the natural urinary channel—requiring zero external skin incisions.
1. Microscopic Entry & Visualization
Under light sedation or anesthesia, Dr. Samadi inserts a slender, lighted scope (cystoscope) through the urethra to directly view the prostate blockage on high-definition monitors.
2. Targeted Photoselective Vaporization
A thin, flexible laser fiber is threaded through the scope. The GreenLight system emits a specialized 532nm wavelength laser that is intensely absorbed by the hemoglobin (red blood cells) in prostate tissue. The moment the laser strikes the overgrown tissue, the energy instantly converts intracellular water to steam, vaporizing the tissue into harmless vapor while simultaneously sealing the underlying blood vessels.
3. Recreating a Wide-Open Channel
Dr. Samadi systematically sweeps the laser across the obstructing prostate lobes, instantly carving out a wide, unobstructed cavity. Within 30 to 45 minutes, the physical constriction is gone, leaving a clear pathway for urine to flow freely from the bladder.
Why GreenLight™ Laser Outperforms Traditional Options
For decades, Transurethral Resection of the Prostate (TURP)—cutting tissue away with an electrified wire loop—was the default surgery for BPH. While effective, traditional TURP carries substantial risks of heavy bleeding, TURP syndrome (fluid overload), and lengthy hospitalizations.
| Recovery / Clinical Feature | Traditional TURP Surgery | Dr. Samadi’s GreenLight™ Laser PVP |
| Surgical Incisions | None (Transurethral) | None (Transurethral) |
| Bleeding Risk | Moderate to High; requires coagulation | Near-Zero; laser seals vessels on contact |
| Blood Thinner Candidacy | Dangerous; medication must be stopped | Safe for men who cannot stop anticoagulants |
| Facility Profile | Multi-day hospital admission | Outpatient procedure (home same day) |
| Catheter Duration | Typically 3 to 5 days | 24 hours or fewer in most cases |
| Erectile Potency | Higher risk of nerve injury | 100% Preservation of natural erections |
Key Patient Advantages: Speed, Safety, and Preserved Virility
1. Safe for Men on Blood Thinners
Many men in their 60s, 70s, and 80s who suffer from BPH also manage cardiovascular conditions requiring blood thinners (like Plavix, Eliquis, or Coumadin). Because the GreenLight laser seals blood vessels as it vaporizes, Dr. Samadi can safely perform the procedure on men who cannot pause their anti-coagulation therapy—a monumental safety advantage over traditional surgery.
2. Preserving Erectile Function and Intimacy
The GreenLight laser light penetrates only a fraction of a millimeter into deep tissue, ensuring that thermal energy never spreads to the delicate neurovascular bundles running along the outside of the prostate. This precise energy containment preserves baseline erectile function and natural orgasmic sensation.
3. Rapid Symptom Relief & Same-Day Discharge
Because the procedure is bloodless and minimally traumatic, over 95% of Dr. Samadi’s GreenLight patients return home the exact same day. Patients experience immediate, dramatic improvements in stream force and bladder emptying within days of the short recovery window.
Conclusion + CTA
Living with an enlarged prostate does not mean you have to stay chained to daily medications or undergo risky, open surgical procedures. Through the precision of GreenLight™ Laser Vaporization at St. Francis Hospital in Roslyn, Dr. David Samadi restores effortless bladder function, allowing you to reclaim uninterrupted sleep, daily comfort, and your overall quality of life.
