Renal arteries: anatomic study for surgical and radiological practice
1Department of Anatomy, State University of Rio de Janeiro (UERJ), Brazil.
Insights
This study details the varied renal arterial supply in 266 kidneys, identifying common and rare variations. These anatomical findings have significant implications for urological and radiological procedures.
Area of Science:
- Anatomy
- Urology
- Radiology
Background:
- The renal arterial supply is crucial for kidney function and surgical interventions.
- Variations in renal vasculature can complicate procedures and impact outcomes.
Purpose of the Study:
- To systematically analyze and document the anatomical variations of the renal arterial supply.
- To discuss the clinical significance of these variations in various surgical and radiological contexts.
Main Methods:
- Dissection of 266 kidneys from 133 fixed adult subjects.
- Detailed analysis and categorization of renal arterial branching patterns.
Main Results:
- A single hilar artery was observed in 53.3% of cases.
- Variations included extra-hilar branches (14.3%), multiple hilar arteries (7.9% to 1.9%), and polar arteries (6.8% to 5.3%).
- Other anatomical variations accounted for 8.5% of the kidneys studied.
Conclusions:
- Understanding renal arterial variations is essential for successful kidney transplantation and renovascular procedures.
- These findings are critical for interpreting radiological imaging and performing safe oncologic and conservative renal surgeries.
Abstract:
The renal arterial supply was analyzed in 266 kidneys dissected from 133 fixed adults subjects. The anatomical findings are presented: 1 hilar artery in 53.3% of the cases, 1 hilar artery with 1 superior pole extra-hilar branch in 14.3%, 2 hilar arteries in 7.9%, 3 hilar arteries in 1.9%, superior polar artery in 6.8%, inferior polar artery in 5.3% and other variations in 8.5%. The urological and radiological implications of these findings in kidney transplantation, renovascular hypertension, renal trauma, interventional radiology, conservative surgery and oncologic surgery are discussed.
