Scintigraphy (renal)

The most commonly performed investigations are:

• dynamic renal imaging or renography - for functional information
• static renal imaging - for morphological information

Advantages of renal scintigraphy include:

• minimal radiation exposure
• non-invasive
• easily reproduced
• no urine collection necessary
• can be performed on an out-patient basis
• few adverse effects reported

Indications include:

• obstructive uropathy - before and after surgery
• renovascular hypertension - before and after angioplasty
• acute renal failure after treatment
• vesicoureteric reflux in children
