While urinating, you get bubbles. what do they mean?

Here are some...: Bubbles form if there is molecules to sandwich water molecules, like that occurring in soap bubbles. The molecules in urine to sandwich water molecules may include amino acids, proteins like albumin, glucose, etc. The higher the affinity of these sandwiching molecules, the more likely to form bubbles to last. Clinically and usually, nothing is significant after ok in testing UA & renal function.
