Retrograde urography involves injection of a contrast medium directly into the renal pelvis through a catheter inserted into the ureter, allowing for radiologic examination of the renal pelvis and ureter. This is an alternative to intravenous urography, which involves injection of a contrast medium into a vein and subsequent visualization of the urinary tract via radiography. Suprapubic radiography and transurethral radiography are not typically used for evaluation of the renal pelvis and ureter.
