Summary
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.
