The CT Angiographic Prevalence of Renal Accessory Arteries in Kenya

Abstract

The understanding of vascular anatomy of kidneys has gained remarkable significance in both medical and surgical disciplines. The science of r enal transplantation intensifies a need for recognizing the variation in renal vascular anatomy in different population and ethnicities. CT angiography is a less invasive modality for assessing the renal vascular anatomy of potential kidney donors as not e very healthy person wishing to donate kidney is a suitable candidate for this highly specialized procedure. Difficulty in surgical anastomosis of vessels has been reported because of anatomical complexity. There is diversity in anatomical variation in diff erent population, ethnic group and geography. In Kenya not much work has been done in this area using living donors. The aim of this study was set to determine the prevalence of renal accessory arteries among African adults in Kenya and establish the kidne y side commonly presents with accessory arteries. The study was a three - year cross sectional descriptive study conducted at Kenyatta National Hospital from June 2008 to June 2011. A total of 204 cases including 103 (50.5%) females and 101 (49.5%) males wer e recruited for CTA. The mean age of participants was 47.16 years (SD 18.32). The prevalence of accessory arteries was 11.3% and prevalence of left sided accessory arteries (7.4%) was higher than right - sided accessory arteries (4.9%). The radiological prev alence of Accessory renal arteries among African adults in Kenya is more than 11% left kidney commonly presents with unilateral accessory renal arteries more than the right kidne
