Final answer:
The medical term for an X-ray image of the renal pelvis after contrast dye is injected into the ureter is retrograde pyelogram. This procedure is used to diagnose and evaluate various conditions of the urinary system. Other imaging tests, such as intravenous pyelogram (IVP), may also be used.
Step-by-step explanation:
The medical term for an X-ray image of the renal pelvis after contrast dye is injected into the ureter is retrograde pyelogram. In a retrograde pyelogram, a contrast dye is inserted through a catheter into the ureter, and then an X-ray is taken to visualize the renal pelvis and the ureter.
This procedure is used to diagnose and evaluate various conditions of the urinary system, such as kidney stones, kidney infections, and blockages in the ureter. It helps the healthcare provider to assess the structure and function of the kidneys and detect any abnormalities.
Other imaging tests, such as intravenous pyelogram (IVP), may also be used to examine the renal pelvis and ureters, but in an IVP, the contrast dye is injected into a vein rather than directly into the ureter.
