Introduction: Introduction: Each kidney is typically drained by a single renal vein, though variations exist. Sometimes, more than one renal vein may drain the kidneys, which is clinically significant as they often play a significant role in surgeries related to the kidneys.
Aim: To measure the morphological parameters of renal veins, as well as additional renal veins if present.
Materials and Methods: A cross-sectional study was conducted in the Department of Anatomy, Assam Medical College and Hospital, Dibrugarh, Assam, India from October 2021 to October 2024. A total number of 52 formalin-fixed human cadavers of both sexes were dissected, which included both adults (n=17) and perinatal cadavers (n=35). The parameters were the length and diameter of the renal veins and, if present, those of accessory renal veins. The length of the renal veins was measured with a measuring scale. The diameter of the renal veins was measured by using Vernier’s calliper. Continuous variables were reported as Mean±Standard Deviation. The categorical findings were expressed in percentages.
Results: Of the 52 cadavers studied, 37 (71.2%) were males, 15 (28.8%) were females. The study included 104 renal veins. The length of the adult Right Renal Vein (RRV) and Left Renal Vein (LRV) was 2.46±0.41 cm and 7.06±0.51 cm. In the case of a perinatal cadaver, the length of the right and LRVs was 1.21±0.3 cm and 1.86±0.5 cm, respectively. Of the 52, 3 (5.8%), showed the presence of accessory renal veins. Accessory renal vein on the left-side was present in 2 (3.8%) cadavers, whereas 1 (1.9%) cadaver showed it on the right-side.
Conclusion: The variations and course of renal veins help in nephrectomy and renal transplantation surgeries.
