The aim of the procedure is to pull back the parts of the prostate that are pressing on the urethra so that it's no longer blocked. It's designed to cause less damage than surgery or other procedures. It's also claimed that there is a lower risk of incontinence and problems with erections.
The man is given a local or general anaesthetic. A device is inserted into his urethra. The device has a camera on the end so that the surgeon can see what they are doing. A very thin implant (a prostatic urethral lift implant) is inserted through the prostate and anchored outside it. A tiny bar is put onto the implant still inside the urethra and fixed so that it squeezes the enlarged prostate and widens the urethra. Several implants may be used.
