While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Anatomical variations of the renal artery: a computerized tomographic angiogram study in living kidney donors at a Nigerian Kidney Transplant Center
Abstract
Background: Understanding of the renal vascular anatomy is key to a safe and successful donor nephrectomy, which ulti- mately impacts on the renal graft function and survival in kidney transplant recipients.
Objective: To report the various anatomical configurations of the renal artery identified in living kidney donors in a Nige- rian kidney transplant institution .
Materials and Methods: The computerized tomography angiograms of 100 consecutive living kidney donors were pro- spectively reviewed over an 18-month period. Anatomical variations of the renal arteries including accessory arteries and early divisions were noted. Duration of surgery and ischemic time were recorded intra-operatively. Data analysis was carried out using IBM SPSS version 20.
Results: There were variations in renal artery configuration in 50 (50%) cases, 32% were accessory renal arteries while 18% were early branches of the renal artery. The classical bilateral solitary renal arteries were found in 50 (50%) of potential do- nors. There was statistically significant longer operating and ischemic time in donors with multiple renal arteries as compared with solitary arteries (p<0.05).
Conclusion: There are a wide variety of renal artery configurations seen in potential kidney donors. The classical solitary renal artery remains the commonest and most favourable configuration for donor nephrectomy and transplantation.
Keywords: Renal artery; variations; living kidney donors.
