Invisible Needle Vasectomy - The Vasectomist
  • LOCAL ANAESTHESIA

    No Needle Anaesthesia

ULTRA-FINE NEEDLE

What needle is used for no scalpel vasectomy?

Let’s face it, most guys don’t want a needle ‘down there!’

A variety of different needle sizes may be used for no scalpel vasectomy. See this needle comparison chart. The diameter of a 33G needle is 0.2 mm which is considerably finer than a needle used for taking blood or giving a vaccine.

The 33G causes minimal to no discomfort.  Bear in mind that the 33G needle is the same diameter as that used by kids for their daily diabetes needles.  You more likely to feel the anaesthetic ‘going in’ rather than the needle itself.

Dr Beatty uses a premium 33g needle which is marketed by the manufacturers as the so-called ‘invisible needle.‘  The manufacturers claim that the needle is ‘the thinnest needle to date.’ What can be stated is that the needle is the finest needle available for clinical use in Australia. Only Finer needles exist in the research setting.

NO NEEDLE ANAESTHESIA

What is No Needle Anaesthesia?

The ®Madajet no needle device is not approved by The TGA for use in Australia.

Monash University recently compared no needle with conventional needle anaesthesia in 60 men undergoing surgical sperm retrieval. They concluded that ‘for local anesthesia in patients undergoing surgical sperm retrieval, MadaJet produces less pain and discomfort with quicker time to onset and offset of anesthesia compared with conventional needle injection.’

The study compared no needle with a 25g needle which may be considered wide compared to ultra fine needles.

The device is widely used in The US and Canada but is not approved for use in Australia and is therefore not an option for Australian men.

WHAT WILL I FEEL?

No Scalpel Vasectomy is very comfortably performed under local anaesthetic.

You will feel:

  • The tinest of ‘pricks’ using a premium 33g needle.
  • The needle may pass unnoticed.
  • A little pressure may be felt as the local anaesthetic starts to take effect.
  • Some movement during the procedure.
  • A sense of pressure may be felt for 2-3 seconds as the tubes are accessed. Dr Beatty will count down 3,2,1 to let you know that you may feel some pressure for a couple of seconds.

VASECTOMY UNDER SEDATION?

Full sedation is a ‘general anaesthetic’ (GA) requiring an anaesthetist with access to the full paraphernalia of emergency care. A vasectomy rarely needs to be performed under sedation.

Local anaesthetic vasectomy using no-needle anaesthesia is safe, quick and painless. The 2015 national US Vasectomy guideline makes a positive recommendation that local anaesthetic is routine used: ‘Vasectomy should be performed with local anesthesia with or without oral sedation’ (statement 5).

In The UK, vasectomy under GA is almost unheard of. Satisfaction with local-anaesthetic vasectomy is very high.

There are very few patients who are not nervous about having a vasectomy. However, there are lots of ways to reduce anxiety – and a GA is, in Dr Beatty’s opinion, a last resort for guys who have extreme anxiety. GA is also suited for guys with challenging anatomy because the testicles drop by around 2cm during a general anaesthetic. The pre-vasectomy consultation will pick up any issues requiring a referral for vasectomy under a general anaesthetic.
