title: Accessory renal vessels at the upper and lower pole of the kidney: a cadaveric study with clinical implications.
abstract: The renal artery is known to exhibit variations in its number and position. The present study was performed on 50 cadaveric kidneys to observe the topographical anatomy of the accessory renal arteries (ARA) entering the upper or lower poles of the kidney. Out of 50 kidney cadaveric specimens (irrespective of sex) studied, 2 kidneys (4%) showed the presence of ARA. The presence of ARA was observed on the left and right kidneys, respectively. In one left kidney, we observed in addition to the usual renal artery, an ARA near the lower pole of the kidney which divided into anterior and posterior branches. Another right kidney specimen exhibited the presence of single and double ARA at the upper and the lower poles, respectively. The presence of ARA, both at the upper and lower poles is a rare entity. No medical history of the cadavers was available to corroborate the clinical findings. Additional renal vessels may signify a developmental defect. Anatomical knowledge of the variations in the renal vascular supply may be important for abdominal imaging studies and surgical operations involving renal transplantations. The present study discusses in detail the anatomical features and clinical implications of ARA located at both the upper and lower poles of the kidney (Fig. 2, Ref. 15).
