I don’t think realistic texture is all that important. Most of the practice is more about the technique and maintaining sterility throughout.

One thing that comes to mind would be material for practice. You might need special filament to make it “realistic”?
If you’re looking for a scale model of the organ system, that should exist and hopefully others know more :)

Just to clarify, you don’t care about the sterility of specific part? Fdm prints in particular can’t be kept sterile.
I assume you need it to be flexible-ish at the very least, which you might achieve with TPU, but I still say mold casting is the way to go.

The part itself don’t need to be sterile. The important part is maintaining sterile technique, which is the main issue with catheters due to the area involved and the amount of tubing that goes in.
Whether or not the stuff is actually sterile doesn’t matter.

Exactly this. It sounds like OP wants it to be an instructional aid. It does not need to be sterile, the people practicing need to practice how to don sterile gloves, then drape and prep the site sterilly and insert the catheter correctly.

It wouldn’t need to be sterile at all, it’s just a teaching tool for patients before they are discharged home. Showing exactly where things go and why is much easier to understand when you can see it, an absolute ideal model would be a cross section.

I suspect the most useful approach is to print a mold and cast using soft resin of some sort.

Yep this. 3d print works great for silicon casting

And to cast it soft too.

Needs a stiff core.
For, uh, reasons.
