I have urination problems, could it be my kidneys?

Dear Doctor
I have some problem with urination. After 5 minutes of drinking a glass of water or even some sips, I feel to quickly release the urine because it pressurizes my right side as shown in the attached picture. The red color and light red color shows the intensity of the pressure. After I finish releasing the urine, it still releases for 10-15 minutes in the form of drops. I need to frequently urinate. I am also going to attach my recent test reposts of LFT, RFT and Urine. I am worried about functioning of my kidneys.
