This ultrasound guided cysto is also the way my clinic goes about gettinf a sterile sample.
There are many urine test however that do not require sterile urine. We had sterile specimen containers we caught it in.
But for a few of the test it must be sterile and then thats when we used the cystocentesis way. Very quick, much less painful. Passing a catheter can be very uncomfortable and cause alot of irritation to the dog.
However the cysto urine sample can show a tiny amount if blood sample from poking the needle in.
For a regular u/a the best way is free catch , catching in a sterile container. This way you know if blood is present that its for real.
This is how my clinic does it anyway
Its interesting to see the way different clinics and drs practice.
