Is it possible to have kidney stones, but not have any evidence of them in urine samples or ultrasounds?

In brief: Yes

These stones may be too small see on ultrasound and a routine urinalysis may easily miss stones as well.
The best test for diagnosing the majority of stones in the urinary tract is a ct scan without contrast. This will detect the majority of kidney stones but a few may be missed occasionally.
