CONGENITAL RENAL ANOMALIES: Radiological evaluation
ABSTRACT NO: 143
ANOMALIES IN POSITION: Rotational anomalies Renal ectopia: Ipsilateral;
crossed
ANOMALIES IN FORM: Horse shoe kidney Disc kidney Crossed fused ectopia
ANOMALIES IN NUMBER: Supernumerary kidneys Renal agenesis ANOMALIES IN SIZE: Renal hypoplasia: Dwarf kidney Thin kidney Renal dysplasia Compensatory hypertrophy
ANOMALIES IN STRUCTURE: Large septae of Bertin Fetal lobulation Congenital polar
enlargement Pseudotumours Congenital intendation Congenital cysts
ANOMALIES OF ROTATION: Nonrotation: pelvis lies
anterior Incomplete rotation: pelvis
lies between 30*- 90* Reverse rotation: pelvis
lies anterolateral Excessive rotation: pelvis
lies posterior Transverse pelvis superior/
inferior

Renal ectopia:
Congenital abnormal location Ipsilateral ectopia: Abdominal: Above iliac crest, below L2 Iliac: opposite iliac crest/ in iliac fossa Pelvic: in true pelvis Crossed ectopia: kidney lies in the side
opposite the ureteric orifice
