Summary
Gadolinium-enhanced MR imaging accurately assesses kidney anatomy in living donors. This minimally invasive technique provides comprehensive pre-surgical evaluation for potential laparoscopic renal donors.
Area of Science:
- Radiology
- Nephrology
- Surgical Anatomy
Background:
- Laparoscopic donor nephrectomy requires precise anatomical knowledge.
- Pre-operative imaging is crucial for identifying potential complications.
Purpose of the Study:
- To evaluate gadolinium-enhanced MR imaging for assessing renal arterial, venous, and ureteric anatomy in potential laparoscopic renal donors.
- To compare MR imaging findings with surgical outcomes.
Main Methods:
- Sixty-four patients underwent MR imaging and MR angiography prior to laparoscopic donor nephrectomy.
- Imaging results were prospectively reviewed and compared to surgical findings.
Main Results:
- MR imaging and angiography demonstrated high accuracy in identifying normal and anomalous renal vascular anatomy.
- Sensitivity for arterial anomalies was 89.4%, and for venous anomalies was 98.3%.
- No significant ureteric anomalies were detected pre-operatively or intra-operatively.
Conclusions:
- Renal MR imaging with gadolinium enhancement offers a safe and accurate method for comprehensive donor assessment.
- This technique is a valuable, minimally invasive tool for evaluating living renal donors before transplantation.
