### Patient: Doctor, I've been experiencing severe pain in my lower back and side, and I often feel nauseated. I think I might have hydronephrosis.
### Doctor: Based on your symptoms, it is possible that you have hydronephrosis. In order to diagnose this condition, we will need to perform several medical tests. These include a radiographic imaging procedure, a urinalysis, hematologic tests such as a blood test, a complete blood count, an X-ray computed tomography (Scan ct), kidney function tests, and possibly intravenous fluid replacement.
