When medication is not enough for prostate symptoms, or complications such as retention occur, a procedure becomes an option. Today most of these are done endoscopically, without opening the abdomen.

Transurethral resection (TURP)

One of the best-known and longest-established options. The enlarged tissue is removed in small pieces through the scope, widening the channel and easing symptoms. It suits many medium-sized prostates.

Water vapour therapy (Rezūm)

Through the scope, steam is injected into the enlarged tissue, which then shrinks over the following weeks. It is minimally invasive and suits certain sizes and patients.

Endoscopic enucleation (AEEP)

The entire enlarged part is removed from inside the prostate capsule through the scope. Its strength is that even very large prostates can be treated without open surgery.

How is the right option chosen?

• The size and shape of the prostate
• How severe the symptoms are and whether there are complications
• General health and current medication
• The patient’s priorities, such as preserving ejaculation
