Abstract Background: Renal transplantation is the treatment of choice for people who suffer from end stage renal disease. Renal vascular anatomy is known for presenting a wide range of variations. Kidneys with variant renal vascular anatomy when used as a graft appear to be a potential risk factor that could impair the outcome of kidney transplantation. Information on renal vascular variations and its implication in the surgical outcome of renal transplantation has not been well studied. Hence, the present study was aimed to evaluate the outcomes of transplantation of renal allografts with variant renal vasculature as compared to allografts without renal vascular variation in the national kidney transplantation center of Ethiopia.Methods: A health institution based cross-sectional study was conducted. A retrospective review of the medical records of kidney recipients was performed. A total of 120 renal transplant recipient’s medical records were evaluated. Chi-square test and Independent t test was used to compare the surgical outcomes of renal transplantation. Graft survival was expressed using Kaplan-Meier curves, and was compared using the log-rank test. P values less than 0.05 was considered as statistically significant. Result: Evaluation of the renal transplant outcomes did not have shown a significant difference in the postoperative complication rate, rate of delayed graft function (DGF), creatinine clearance levels at 1 , 6, or 12 months postoperatively, and 1-year graft survival among recipients of allografts with and without renal vascular variations. However, operation time and the length of hospital stay were significantly longer among recipients of allografts with variant vasculature.Conclusion: No significant difference was noted in the outcomes of transplantation of renal allografts with and without vascular variations. Hence, renal allografts with vascular variations are safe to be recruited for transplantation as to this study.

BACKGROUND Computed tomographic coronary angiogram (CTCA) is a non-invasive test with a negative predictive value of nearly 100% for the detection of coronary artery study. While diagnostic yield of a dedicated CTCA with bubble contrast is not yet evaluated OBJECTIVE To assess the diagnostic performance of injected bubble contrast and ability to measure difference in hounsfield units and use it as a "negative contrast" in computed tomographic METHODS This is a single center, single patient study. Baseline acquisition of a non-contrast CT scan was acquired to get hounsfield unit count in the aorta and pulmonary artery- (Calcium scan protocol) 1.4 mGy (19.5 mGy/cm). Secondly, Echo contrasts (Definity) - 5mls was injected and an echocardiogram confirmed filling in the aortic region. Finally, bubble contrast (1ml air, 8mls water and 1mls blood was drawn up and agitated through a 3 way tap) - was injected, a timing run was initiated to calculate for the bubbles to opacity the pulmonary artery. The same scan protocol was used– 1.4 mGy (19.5 mGy/cm). RESULTS Hounsfield units’ difference in the aorta and pulmonary artery from baseline compared to echo contrast and bubble contrast were not significant. CONCLUSIONS We believe this is the first ever recorded case to use bubbles as CT contrast. While results were not significant, secondary to small volume of bubbles injected. Further research needs to be implemented to assess clinical difference with amount of bubbles and volume required. CLINICALTRIAL Single centre study
