Summary

This study found that 27.7% of individuals have additional renal arteries, with variations noted between sexes and races. Understanding these renal arterial variations is crucial for surgical and radiological procedures.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Urology

Background:

  • Renal arterial variations require updated definitions due to surgical and uro-radiological advancements.
  • Additional renal arteries are a common anatomical variation with implications for various medical procedures.

Purpose of the Study:

  • To determine the incidence of additional renal arteries.
  • To analyze the morphometry of these additional vessels.
  • To highlight the clinical significance of identifying renal arterial variations.

Main Methods:

  • Retrospective analysis of 130 renal angiograms from transplant donors and 32 cadaver kidneys.
  • Examination of 74 en-bloc cadaver kidney pairs.
  • Data collection on sex, race, and morphometric details of additional renal arteries.

Main Results:

  • The overall incidence of additional renal arteries was 27.7%.
  • First additional arteries occurred in 23.2% and second in 4.5%, more frequently on the left.
  • Significant differences in incidence were observed between sexes and races, though morphometry showed no significant variations.

Conclusions:

  • The incidence of additional renal arteries aligns with existing literature.
  • Detailed morphometry of these vessels was recorded, offering unique insights.
  • Accurate identification of renal arterial variations is essential for successful renal transplantation, vascular surgeries, and uro-radiological interventions.
