Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Laser vapourization of prostate (PVP) compared to TURP. PVP uses a 120W green light laser to vapourize prostate tissue to create an opening to allow an improved urinary flow. The procedure takes between 30 and 80 minutes. There is very little bleeding and saline can be used to washout the bladder.
Intervention code [1] 256689 0
Treatment: Surgery
Comparator / control treatment
TURP is the long established "gold standard" to improve urinary flow blocked by an enlarged prostate. An electrical current is used to remove chips of prostate. Whilst generally quicker than PVP there are risks of bleeding and fluid absorption. Saline cannot be used as an irrigant as it will not allow the passage of an electrical current.

Active

Summary
Brief summary
PVP is a new procedure that may one day be able to replace TURP as the main treatment for men with benign prostate enlargement. There has only ever been one randomized controlled trial of PVP with TURP and this was using the now outdated 80W model. Recent advice from the UK National Institute for Health and Clinical Excellence has stated that PVP should only be used in the context of randomized controlled trials. We intend to assess whether the procedure has long term benefits for patients and whether it is cost efective for health providers.
