UNILATERAL LEFT MALROTATED KIDNEY WITH VASCULAR AND HILAR VARIATIONS: A CADAVARIC CASE REPORT

Abstract

During our dissection classes for abdomen, some abnormal appearance in a male cadaver in the Department of Anatomy, Rajendra Institute of Medical science, Ranchi was observed 1. The anomaly in the position of the kidney in the abdomen i.e., left kidney of the cadaver was lying below the normal level so much that the right kidney appeared to be higher than it with hilum facing ventromedially. (Usually, Right kidney lies somewhat lower than the left because of the relationship with the liver, and also the hilum is medial facing). (Figure.1) 2. Also, kidney is usually drained by one renal artery and one renal vein. But in this case the left kidney was drained by two renal arteries and both of them originated from the abdominal aorta itself. (Figure.2) The accessory renal artery was originating from the level above the origin of primary renal artery, and entering the hilum hence the arrangements of left renal hilum vary with respect to the normal arrangement. 3. Hilum relations that usually holds anterior to posterior, is renal vein exits renal artery enters and the renal pelvis exits, but in this case the left kidney hilum relations were also altered from anterior to posterior I.e., left renal artery enters, left renal vein exits, accessory renal artery enters and renal pelvis exits the hilum.
