### Patient: Doctor, I think I have urethritis. I've been experiencing a burning sensation while peeing and there's a constant urge to go to the bathroom.
### Doctor: Okay, to properly diagnose urethritis, we will need to perform a few medical tests. We will start with a urinalysis, a chlamydia test, and a microscopic examination to check for bacterial smear, culture, and toxicology. In addition, we may need to do a blood culture and an HIV screen. If necessary, we'll perform an endoscopy and endoscopic biopsy of the urinary tract. We may also need to insert an indwelling catheter.
