Magnetic Resonance Urography (MRU)
- Magnetic Resonance Urography offers excellent anatomical visualisation and multiplanar 3D reconstruction as well as an assessment of differential renal function and drainage. 16,17 It provides detailed information on renal pathology within a single study which correlates well with surgical findings. 18,19
- MRU can accurately demonstrate all the common causes of antenatally detected hydronephrosis and guide subsequent management. 18,20
- Gadolinium-DTPA dimeglumine is used to assess the excretion and drainage of the kidneys.

Advantages include:
● Assessment of anatomical structure and function in a single study
● Advoids ionising radiation
-
Disadvantages include:
● May require sedation and anaesthesia in young children
● Relatively expensive with limited availability and requiring local expertise
