### Patient: Doctor, I have been experiencing difficulty in passing urine lately. It feels like something is blocking my bladder. What should I do?
### Doctor: Based on your symptoms, we need to perform a series of medical tests to determine the cause of your bladder obstruction. We'll start with a urinalysis, rectal examination, and a prostate specific antigen measurement (Prostate specific antigen test). These tests will help us evaluate your condition. We may also need to perform an ultrasonography (Ultrasound) and other diagnostic procedures such as an interview or consultation. If necessary, we may have to insert a catheter into your urinary bladder or perform an excision (removal) to treat your condition.
