ANGLOGRAPHIC VARIATIONS OF RENAL ARTERY AMONG DONORS OF KIDNEY IN DUHOK CITY

Abstract

Background and objectives Renal artery variations are not uncommon. It can be investigated by many means; so far renal conventional angiography is dependable in the disclosure of the anatomical variations of the renal artery. In order to take all the steps of successful transplantation, the kidney of potential donor should be studied thoroughly mainly its function and anatomy. From our side, we tried to study the prevalence of anatomical variations of renal artery by angiography in donors of kidney in Duhok city.Methods Case-series study involved eighty three (83) kidney donors; aged between 18- 47 years (24+-2.1), 76 of them were males, referred from Duhok transplantation unit and assumed to be healthy after screening for any medical illness. In Cath-Lab of Azadi Heart Center in Duhok renal artery angiograms were obtained. Each angiogram consists of rightand left renal artery images with a central aortogram. The data were collected from the 1st of January 2010 to 1st of July 2011. This study was approved by the Scientific Review Committee at Duhok College of Medicine.Results Fifty four 54(65.1%) of them had normal single right and left renal arteries, but theremaining 29(34.9%) of supposed donors had anatomical variations of renal artery. Right renal artery: 14(16%) out of 83 showed variations (Double was 11,Trifurcate was 3 cases).Left renal artery: 21(25%) out of 83 had variations (Double was 17, Trifurcate was 4 cases.5(6%) were bilateral. Main right and left renal artery originated mainly between L1 and L2 in 97.5%, 99% respectively.Conclusions The results of this study indicated that the anatomical variations of renal artery is common and the anatomy of renal artery ultimately is necessary to be known prior of transplantation.
