### Patient: Doctor, I have been experiencing pain and difficulty while urinating. Sometimes there is blood in my urine as well. I am worried that I may have a urethral stricture. 
### Doctor: Based on your symptoms, I recommend a series of medical tests. Firstly, we need to conduct a urinalysis to check for any signs of infection or inflammation in the urinary tract. Then, we will have to perform procedures on the urethra to examine its structure, such as an endoscopy or endoscopic biopsy. Additionally, we may need to do an ultrasonography to get a better look at the urinary system. Depending on the results of these tests, we may also have to conduct a prostate specific antigen measurement, perform a rectal examination, and other diagnostic procedures to confirm the diagnosis.
