ABSTRACT
Further imaging may be planned when the neonate is stable and full discussion of the clinical, laboratory and radiological findings have been evaluated by the clinical team. This is even more important if there are other congenital abnormalities unrelated to the urinary tract. Anatomy is frequently fully understood and information relating to the individual kidney function is now required. This requires use of radioisotopes. Transitional nephrology must be borne in mind, since this governs the way both 99mTc-DTPA and contrast for an IVU as well as 99mTc-DMSA and 99mTc-MAG3 are handled by the kidney.
