Enucleation vs Resection vs Vaporisation

The three philosophies

A BPH operation removes tissue that blocks urine flow. Surgeons use three different philosophies to do that.

Resection takes tissue away in small chips. Vaporisation burns tissue until it is gone. Enucleation lifts whole lobes away in one piece.

Each philosophy has its own tools, its own pace, and its own trade-offs.

Resection — shaving tissue in chips

Resection has been around since the 1930s. A resectoscope holds a wire loop that cuts small chips as it slides back and forth.

Each chip is rinsed out through the scope. The surgeon works section by section until the outlet is open.

A modern version is bipolar TURP, which uses current between two points to reduce the risk of fluid absorption. Both monopolar and bipolar versions are still widely used today.

Vaporisation — burning tissue away

Vaporisation uses heat to turn tissue into steam and carbon. Nothing is sent to the laboratory, because the tissue is destroyed on the spot.

A common vaporisation approach is GreenLight PVP, which uses a laser tuned to the colour of haemoglobin. Other tools include plasma buttons and certain thulium settings.

Recovery tends to be fast, because the cut edge is sealed during the burn. The trade-off is a loss of tissue that could otherwise be sent for pathology.

Enucleation — lifting whole lobes

Enucleation peels whole lobes from the outer capsule of the prostate. A widely used modern form is HoLEP, which uses a holmium:YAG laser to separate the plane.

Once a lobe is free, it is pushed into the bladder. A separate tool called a morcellator then breaks it up and suctions the fragments out through the scope.

The full lobe can be sent to pathology. The plane is also clean, which tends to leave less tissue behind.

How they compare

A 2025 study that compared TURP, GreenLight PVP, and HoLEP in men with small-volume BPH reported similar effectiveness across the three techniques and a higher rate of bladder-neck contracture and early incontinence after TURP[¹]. In that specific comparison, the two laser arms recorded fewer such events than the TURP arm.

Different centres and prostate sizes can change the picture. Enucleation is often used for very large glands because the full lobe can be separated in one plane; resection is typically used for smaller to moderate volumes.

The right technique for you depends on your anatomy, your surgeon's training, and what trade-offs matter to you.

What this means for you

If your surgeon says "TURP", they mean resection. If they say "PVP" or "laser vaporisation", they mean vaporisation. If they say "HoLEP", "ThuLEP", or "enucleation", they mean lifting whole lobes.

Knowing which philosophy is being proposed helps you understand the rest of the conversation. It also helps you compare numbers fairly when two clinics offer different techniques.

Ask how many cases your surgeon does each year of the philosophy they recommend. Ask what their own rates of re-treatment are over five years.

Plain bottom line

Resection shaves. Vaporisation burns. Enucleation peels.

All three can work well. The choice is made with you, not for you.
