I actually have not tried this yet. I don't think anyone I've worked with does them.
I had never seen anyone do a single incision until today. I rotated into the neutering station and the vet asked me "Do you do neuters with one incision or two?" like it was some sort of routine thing, haha. I was like "...two?" and I think my utterly confused expression made her take pity on me and explain the single incision process. You treat it like a prescrotal incision in a dog, just over the testicles instead - manipulate one over then cut through the median raphe/septum region and get it out, then cut into the other through that same middle incision.

I'm really hoping it goes well since I've wanted to get some emergency experience for a while
