Potential donors for renal transplantation undergo an exhaustive pretty operative examination including medical assessment, laboratory testing and radiological imaging. The goal of imaging in these subjects is to delineate the kidneys and their vascular anatomy to determine if the subject is a suitable donor nephrectomy candidate and if so to assess which kidney maybe technically easier to transplant. This traditional imaging workup has consisted of two examinations, the IV Urogram (IVU) and renal arteriography.
MATERIALS AND METHODS
Totally 18 healthy adults who were potential renal donors were taken for spiral CT angiography. The study was conducted in Viswabharathi Medical College, Penchikalapadu, Kurnool, Andhra Pradesh, between May 2015 and May 2016.
In the present study, supernumerary renal arteries were present in 7 cases (38.8%) and consisted of one artery in 4 cases (11.1%) two arteries in 3 cases (16.6%). Early branching of the main renal artery was seen in one case (2.7%) venous anomaly in the form of retroaortic renal vein. Nonvascular abnormality noted in one case in the form of simple renal cyst in right upper pole (2.7%). Overall, CTA sensitivity, specificity and accuracy are 100%. In one case, axial sections could not find early branching, however, it was depicted in MIPS.
It is superior to conventional angiography in demonstrating accessory renal artery when it is arising from aorta immediately behind the main renal artery in anteroposterior direction and incidental findings like aortic calcifications, renal vein anomalies and renal cysts.
