To understand the normal embryological development of the kidneys. To understand the development of congenital renal ectopia and fusion resulting from failures in embryological development. To be able to recognize and correctly diagnose renal fusion anomalies and ectopia on various imaging modalities. To appreciate some of the pathological consequences of congenital renal and renal tract anomalies.
Congenital renal parenchymal anomalies occur in approximately 1% of the population .
The importance of these anomalies is two-fold.
these anomalies should not be mistaken for pathology themselves.
it is important to recognise that pathology,
such as infection or calculus formation,
can occur more frequently in these anomalies. Embryological development of the kidney and collecting system represents the complex interplay between two embryological structures: the metanephros...
Imaging findings OR Procedure details
Horseshoe kidney Horseshoe kidney is the most common of all renal fusion anomalies,
accounting for 90% of all such anomalies,
and occur in approximately 0.25% of the population,
with a predilection for males in the order of approximately 2:1 . Embryology During ascent towards the renal fossa,
the foetal kidneys cross the umbilical arteries.
Any aberration in position of the umbilical arteries may result in fusion of the bilateral nephrogenic blastemas.
When this fusion occurs at the lower...
The array of congenital renal anomalies is vast and complex.
Fusion and ectopic abnormalities are the result of aberrant fusion or migration of the kidneys during foetal development.
Correct diagnosis relies on understanding the normal embryological development of the kidneys and recognition of anomalies when this normal development has been altered. Most congenital renal and urinary tract abnormalities are asymptomatic and incidentally discovered,
however they often put the patient at higher...
