Summary
Baseline DTPA renography in renal transplant patients can reveal unusual findings. This report details two cases where native polycystic kidneys mimicked abnormalities on renography, impacting transplant assessment.
Area of Science:
- Nephrology
- Radiology
- Transplant Surgery
Background:
- Renal transplantation is a growing surgical procedure.
- Diethylenetriamine pentaacetic acid (DTPA) renography is standard for assessing transplant perfusion and function.
- Native polycystic kidneys can present diagnostic challenges.
Observation:
- Two cases demonstrated atypical findings on baseline DTPA renography.
- These unusual appearances were attributed to the presence of native polycystic kidneys.
Findings:
- Polycystic kidneys can cause abnormal patterns on DTPA renography.
- Misinterpretation could lead to incorrect assessment of transplant status.
Implications:
- Awareness of these potential renographic appearances is crucial for accurate transplant evaluation.
- This highlights the importance of considering native kidney pathology in post-transplant imaging.
- Further investigation may be needed to differentiate native kidney issues from transplant dysfunction.
