Prevalence of Renal Vasculature Anomalies in Asymptomatic Healthy Population
Abstract: An accurate preoperative knowledge of the anatomical vasculature variations is essential for the precise performance of complex operative procedures like partial nephrectomy, renal transplantation and treatment for renal artery stenosis. Anatomic vascular variations differ with ethnicity and population.
Aims and Objective: The study was aimed to determine the variety and prevalence of incidental renal vascular anomalies in healthy and asymptomatic individuals.
Materials and Methods: All prospective potential kidney donors for live related donor nephrectomy who attended Urology OP from July 2012 to December 2014 in Government Medical College Trivandrum underwent MDCT Angiogram to know the renal vasculature variation and these data were retrospectively analysed.
Results: 86 individuals were included in the study and most of them belonged to the age group 40-50 years. In the present study single renal artery was seen in 125 (72.7%) cases and variations were seen in 47 (27.3%). Single renal vein was se3en in 160 (92%) cases and variations in 12 (8%).
Conclusions: Incidental radiographic variations of the renal arteries are common. Vascular variations usually do not preclude kidney donation but definitely need more expertise to deal with.
