Kidney stones: It could be indicative of renal stones (nephrolithiasis), or other problems involving the urinary tract. Best ask your PMD to refer you to a urology specialist so they can investigate it. A renal ultrasound would be a noninvasive way to start the workup.

Microhematuria: Causes of microhematuria (blood not seen by the naked eye) are numerous with causes ranging from completely insignificant causes to potentially life threatening causes. You should give it like a week and have it repeated.. It may actually resolve but if it does not your doctor will be able to guide you on the next step.

Usually harmless: About 1% of healthy adults have lifelong microhematuria, often from a mutation at the Alport locus that does not give the disease but thins the glomerular basement membrane. If you've been imaged and have no tumor or stones, just watch it.
