Can you describe the hooks further (size in proportion to the rest of
the worm and location). If they were simply a bifurcation or
trifurcation of the posterior end of the worm, then they are horsehair
worms. They are from the Phylum Nematomorpha, and there have been cases
of them passing in urine (although it is very rare and some cases maybe
spurious). If you get more specimens I would be happy to identify them
