Place a catheter in the ureter for an X-ray test called retrograde pyelography.

Urological surgery - particularly in retrograde pyelography.

Retrograde pyelography often showed the connection between the renal pelvis and the dilated abdominal lymph vessels.

Antegrade or retrograde pyelography will show similar findings to an IVU but offer a therapeutic option as well.

Anaphylactoid reactions occur rarely, but can occur in response to injected as well as oral and rectal contrast and even retrograde pyelography.

Retrograde pyelography is generally done when an intravenous excretory study (IVP or contrast CT scan) cannot be done because of renal disease or allergy to intravenous contrast.
