Ectopic and Mal-rotated kidney with bilateral hydronephrosis – Case report

Abstract

INTRODUCTION: The term ectopic kidney is used to describe a kidney that is found in a place that
is not its normal anatomic position while malrotation refers to the abnormal orientation of the
kidney. These two are some of the congenital malformations that the kidney is predisposed to in
its embryogenesis.
CASE: The current findings were discovered during routine dissections in the Gross lab of the
Human Anatomy Department of the University of Rwanda
A left ectopic kidney with a relatively larger than normal size (10.5cm × 5.2cm) was found with the
main blood supply arising from the median sacral artery and two other accessory arterial supplies
arising from the abdominal aorta. The kidney was mal-rotated, facing laterally, with the ureter on
both sides dilated.
CONCLUSION: Knowing kidney variations is ever more important with the rate of increase in renal
transplantations and vascular surgeries
