Summary

Accessory renal arteries were found in 20% of Indian cadavers, with unilateral anomalies more common. Understanding these renal artery variations is crucial for kidney surgery and transplantation success.

Area of Science:

  • Anatomy
  • Vascular Anatomy
  • Surgical Anatomy

Background:

  • Renal artery anatomy is critical for urological and transplant procedures.
  • Variations in renal vasculature can complicate surgical interventions.
  • Documentation of renal artery incidence in specific populations is essential.

Purpose of the Study:

  • To document the incidence and characteristics of accessory renal arteries in Indian subjects.
  • To provide anatomical data relevant to renal surgery and transplantation.

Main Methods:

  • Comprehensive dissection of forty cadavers over five years.
  • Detailed examination of renal arterial patterns and measurements.
  • Analysis of accessory renal artery occurrence and laterality.

Main Results:

  • A single main renal artery was present in 80% of specimens.
  • Accessory renal arteries were observed in 20% of specimens (15% unilateral, 5% bilateral).
  • Accessory arteries invariably crossed the anterior aspect of the ureter.

Conclusions:

  • Accessory renal arteries are a significant variation in the Indian population.
  • Knowledge of these variations is vital for kidney retrieval, transplantation, and endourologic procedures.
  • Understanding renal arterial patterns improves surgical planning and patient outcomes.
