### Patient: Doctor, I have been experiencing difficulty passing urine for a few days now, and I also feel some discomfort while doing so. What might be the problem?
### Doctor: Based on your symptoms, it is possible that you are suffering from urinary tract obstruction. To confirm this, we will need to run some medical tests, which includes a urinalysis, hematologic tests (blood test), radiographic imaging procedure, rectal examination, prostate specific antigen measurement (prostate specific antigen test), X-ray computed tomography (scan ct), and ultrasonography (ultrasound). These tests will help us to determine the exact cause of your symptoms and help us to identify the most effective treatment option for you.
