Large obstruction in toilet drain

drain

I am currently working on putting in a basement bathroom. Have a 4 inch drain pipe roughed in, which at it's location is the toilet. Put a camera down to see the condition of the pipe and about 12 feet from the opening is a piece of cinder block. The piece itself is fairly small, about the size of a 2 liter bottle cap. I tried using a vacuum to get the piece out, to no avail. Any suggestions short of tearing the slab up to get it out?

Can I just leave it?

Drain rods with a "drop scraper" attachment might work. Although may take a few tries. If possible try accessing it from someplace closer.

The way this works is that you push it beyond the obstruction and then pull back out. When pulled back the tool opens and scrapes over the floor of the pipe, brings back any debris with it.
