Audit of fine needle aspiration cytology of 120 renal lesions.
Solid renal masses in 120 patients were assessed by percutaneous fine needle aspiration cytology, performed under radiographic guidance. Follow-up was obtained in all but seven cases. Diagnostic sensitivity for 83 tumours in the series was 91.6%, while two false positive reports resulted in a specificity of 93.8%. Positive and negative predictive values were 97.4% and 81.1% respectively. One advantage of the procedure was the ability to cell type neoplasms accurately, which enabled administration of pre-operative chemotherapy in childhood tumours, and selection of appropriate surgical procedures in adults. The technique offered a non-surgical means of confirming primary renal tumours in patients presenting initially with distant metastases, and documenting renal secondaries in cases with malignancy at other sites. The diagnosis of benign or inflammatory lesions permitted institution of definitive therapy.
