Objective: In this study, we aim to present the retrospective results of percutaneous biopsies per-formed on solid kidney lesions in our clinic with the literature.
Materials and Methods: In this retrospective descriptive study approved by the ethics commit-tee in our center, the demographic features and histopathological results of 57 patients who had a solid mass in the kidney between 2017-2020 and underwent ultrasonography-guided percutane-ous kidney biopsy in our interventional radiology clinic were analyzed from the hospital database. Patients without pathology results were excluded from the study.
Results: Our patients consisted of 35 men (61,4%) and 23 women (38,6%). The average age was 59.02±15.33(6-94). We had 1 child and 56 adult patients. 29 of the kidney lesions were locat-ed in the left kidney(50,9%) and 28 were located in the right kidney(49,1%). In 44 patients(77.2%) who had malignant pathology; the results were 41 renal cell carcinoma(93.2%), 2 lung squamous cell carcinoma metastasis(4.5%) and 1 primary metastatic pleomorphic adenoma of the salivary gland(2.3%). In a total of 13 patients(22.8%) whose pathology results were benign; the results were 5 oncocytomas(38.5%), 5 angiomyolipo-ma(38.5%), 2 chronic pyelonephritis(15.4%) and 1 metanephric adenoma(7.6%). Renal cell carcino-ma rate was 71.9% among all lesions.
Conclusion: Radiological methods may not provide sufficient diagnostic data in the differen-tial diagnosis of solid renal masses.In our study, the rates of benign lesions as a result of percutane-ous biopsy were higher compared to the literature. Therefore, we believe that it is remarkable in terms of the impor-tance of preoperative biopsy in solid lesions
