Study Notes

Importance of Renal Anomalies

May indicate abnormal renal development or function, leading to chronic kidney disease.
Can predispose individuals to urinary tract infections.
Might cause urinary obstruction, potentially requiring surgical intervention.
May be linked with non-renal congenital anomalies.

Multicystic Dysplastic Kidney (MCDK)

Results from the failure of the ureteric bud to unite with nephrogenic mesenchyme, leading to cyst formation.
In cases of multicystic dysplastic kidney, normal renal function may not be present, affecting both kidneys.

Renal Dysplasia

Can occur with severe intrauterine vesicoureteric reflux (VUR) or in isolation.
May also be associated with rare syndromes that impact multiple organ systems.
Urinary obstruction may be suspected via ultrasound, particularly indicated by an abnormal bladder in males; follow-up with micturating cystourethrogram (MCUG) is recommended.

Functional Imaging

Functional scans are essential in evaluating renal function and diagnosing urinary tract obstructions.
