Fine-needle aspiration of the adult kidney

Abstract

Renal FNA provides important information that can affect the management of patients with renal masses.

Solid renal masses in adults: Image‐guided fine‐needle aspiration cytology and imaging techniques—“Two Heads Better Than One?”

“…This figure is similar to that reported by Truong et al 3 for malignant lesions and by Renshaw et al 2 for distinguishing benign from malignant lesions.…”

“…13,14 Numerous articles focusing on various aspects of renal FNA have been published over the last 2 decades. [1][2][3][4][5][6][15][16][17][18][19][20][21][22][23][24][25] At this hospital we are currently experiencing a steady fall in requests for renal FNAs, probably as a direct consequence of the increasing accuracy of imaging techniques. This trend has led us to study whether renal FNA has been totally superseded by modern imaging techniques, or whether FNA can still provide useful additional information to assist urologists in deciding on the appropriate surgical course, and, if so, in which specific clinicopathological situations.…”

“…It is necessary to point out that urologists at this hospital did not strictly adhere to the specific criteria for performing image-guided FNAs of renal masses put forward by several authors [1][2][3] : some solid renal masses with obvious radiographic malignant features were referred to FNA by some urologists, whilst other solid renal masses with similar radiographic features were submitted for TN without preoperative image-guided FNA.…”

“…7,8 On revision, renal tumors were grossly stratified into <5.5 cm and >5.5 cm according to the new optimal tumor size breakpoint put forward by Ficarra et al, 9 and were classified according to the histologic and immunohistochemical criteria put forward by Eble et al in the WHO bluebook partially devoted to tumors of the urinary system and published in 2004. 10 We used the criteria put forward by Renshaw et al, 2 Grignon and Staerbel, 11 and Renshaw 12 for review of FNA smears. After the review, no significant modifications were added to the cytologic, histologic, and radiologic reports.…”

“…Its utility is undeniable in space-occupying lesions of various locations; however, the use of FNA in space-occupying lesions of the kidney has recently tended to be confined to specific clinico-pathological conditions, mainly because of the refinement of imaging techniques. [1][2][3][4][5][6] The purpose of this article is 3-fold: to assess the diagnostic accuracy of image-guided 25G-FNA and imaging modalities in a group of 31 patients with solid space-occupying renal lesions who later underwent total nephrectomy (TN) for histologic confirmation; to compare the diagnostic accuracy of the two techniques; and to investigate whether FNA provides valuable information for the clinical management of patients with solid renal masses. …”
