“…Good results for EUS FNA of selected renal tumors were observed in this study. Our overall technical success rate of EUS-guided FNA was 90%, which is within the range previously reported (1,2,4,14) . The cause of failed procedure was due to the posterior aspect of this tumor and the smaller needle-tumor distance.…”

“…The advantages of a biopsy in these cases are the potential to decrease unnecessary treatment of small renal masses and better selection of tumors for active surveillance and minimally invasive ablative therapies (7,14) . The role of needle core biopsy and FNA of renal masses is primarily to rule out non renal cell primary tumors (metastasis and lymphoma) or benign conditions (abscess), which may not require surgery (4) . Biopsy has also been used to confirm the diagnosis and the histological subtype of a renal primary lesion in patients with disseminated metastasis or unresectable retroperitoneal mass.…”

“…Over two thirds of renal masses noted incidentally on abdominal CT-scans for non-urological indications are most likely to be renal cell carcinoma (RCC) (1,4,8,10,15) . Needle biopsy has the potential to decrease the number of unnecessary treatments for benign pathological findings (15) .…”

“…Needle biopsy has the potential to decrease the number of unnecessary treatments for benign pathological findings (15) . Traditionally, tissue sampling of renal lesions has been performed via the percutaneous approach or laparoscopicaly, in order to characterize radiographically indeterminate lesions, confirm malignancy in not surgical candidates or to guide preoperative planning (1,4,10,15) . Few studies addressed this issue and it remains unclear if endoscopic ultrasound (EUS) may have a role in the diagnostic work-up evaluation for RCC (4) .…”

-Context -Tissue sampling of renal masses is traditionally performed via the percutaneous approach or laparoscopicaly.The utility of endoscopic ultrasound to biopsy renal lesions it remains unclear and few cases have been reported. Objectives -To evaluate the feasibility and outcome of endoscopic ultrasound fine needle aspiration of renal tumors. Method -Consecutive subjects undergoing attempted endoscopic ultrasound fine needle aspiration of a kidney mass after evaluation with computerized tomography or magnetic resonance. Results -Ten procedures were performed in nine male patients (median age 54.7 years) on the right (n = 4) and left kidney (n = 4) and bilaterally (n = 1). Kidney masses (median diameter 55 mm ; range 13-160 mm) were located in the upper pole (n = 3), the lower pole (n = 2) and the mesorenal region (n = 3). In two cases, the mass involved more than one kidney region. Surgical resection confirmed renal cell carcinoma in six patients in whom pre-operative endoscopic ultrasound fine needle aspiration demonstrated renal cell carcinoma. No complications were reported. Conclusions -Endoscopic ultrasound fine needle aspiration appears as a safe and feasible procedure with good results and minimal morbidity. HEADINGS -Kidney neoplasms, diagnosis. Ultrasonography. Endoscopic ultrasound-guided fine needle aspiration.
