We use the laser on our all our neuters, including small animals like rats. As you will see from the following pictures there is no bleeding with the laser, which means less anesthesia time and less postoperative pain and swelling.


Student examining rat

All of our rats undergoing surgery get an exam ahead of time. This rat is being examined by one of our student externs

Rat going under anesthesia

Once they pass their exam they are put in a special anesthesia chamber with 100% oxygen and gas anesthesia. Over the next few minutes he slowly becomes anesthetized.

Nurse anesthetist monitoring anesthesia

They are closely observed the whole time by our nurse anesthetist. Notice her laser glasses.

When our patient is fully anesthetized he is taken out of the chamber and put into a special mask for the duration of the surgery

Our patient has been prepped and is ready for surgery


We start the procedure by gently stabilizing the testicle before we turn on the laser


The initial cut is rapid. You can see fat over the testicle as our surgeon gently squeezes the testicle through the opening.


When fully exteriorized you can see a layer of tissue and blood vessels over the testicle. This layer of tissue is called the tunica vaginalis.


The laser cuts through the tunica vaginalis and the testicle is gently pulled out.



The blood supply is now ligated with a special suture that will slowly dissolve over several months


The laser is used to cut the testicle away from the rest of the body


Tissue glue is applied instead of sutures to aid in healing and prevent chewing



This little guy will go home (weighing a few grams less) and heal up in 1-2 days.  There is no need to return for suture removal because no sutures were placed in the scrotum.
