What does pyelogram mean?

A pyelogram is a medical imaging technique used to visualize the renal pelvis and urinary tract, typically through the use of a contrast dye injected into the urinary system. This procedure, often performed via X-ray or CT scan, helps diagnose conditions such as kidney stones, tumors, or urinary obstructions. The images produced provide detailed information about the anatomy and function of the kidneys and urinary system.
