Fine needle aspiration cytology (FNAC) in the evaluation of acute renal allograft rejection.

ABSTRACT

310 Fine needle aspirations biopsies (FNAB) were performed in sixty-five live related renal donor transplant recipients in a prospective study over 2 years. 82.8% of FNAB were adequate for opinion and there were no complications after the procedure. Methodology used and interpretation of FNACs was as described by Von Willebrand and Hayry. The procedure of FNAC had a sensitivity of 83.3%, specificity of 98.3% and accuracy of 96.1%, and statistically significant (p < .001) correlation was noted between FNAC and Needle biopsy. The increment in lymphoblasts, lymphocytes and score above 3 was suggestive of acute cellular rejection. Increment in monocytes and macrophages above 1% in addition to other cells, was suggestive of acute vascular rejection. FNAC was found to be a safe, simple and easy procedure with high specificity and sensitivity.
