Summary
Renal artery stenosis affects 13.5% of kidney transplant recipients. Deteriorating kidney function and biopsy results are key diagnostic indicators, unlike hypertension alone.
Area of Science:
- Nephrology
- Transplant Surgery
- Vascular Surgery
Background:
- Renal artery stenosis (RAS) is a potential complication following kidney transplantation.
- Early diagnosis and management of RAS are crucial for graft survival.
Purpose of the Study:
- To determine the incidence of RAS in cadaver renal transplants.
- To identify clinical and laboratory indicators predictive of RAS in this population.
Main Methods:
- Retrospective analysis of 229 consecutive cadaver renal transplants.
- Evaluation of clinical data, laboratory indices, and renal biopsy findings.
Main Results:
- RAS occurred in 13.5% of transplants.
- Hypertension was not a reliable predictor.
- Deterioration of renal function (excluding other causes) and renal biopsy histology were valuable diagnostic indicators.
Conclusions:
- A significant incidence of RAS exists in cadaver renal transplants.
- A selective diagnostic approach focusing on renal function and biopsy is recommended.
- This approach aids in timely intervention and management of RAS.
