I can certainly sympathize with what you are going through.
Is the urologist in like a group of doctors? Sometimes they will have someone who can see you sooner. Have you called the office and expressed what you are going through?
Certainly, if it is a stone, it can get lodged in the ureter and cause hydronephrosis. The protein could indicate a breakdown in the kidney it's self.
I would encourage you to see if another dr. could see you sooner. Not that you could die over this, but it can become quite painful. A friend of mine (who is an ER nurse) said when her husband had a kidney stone, he drank cranberry juice and it helped him pass it. Your regular dr. could also order a CT, US or KUB to see if they could determine what exactly is going on so the urologist would know what is going on. It doesn't hurt to ask if he/she could order some test other than a urinalysis.
Keep me posted
Praying for you, Kara
