Objective: To evaluate the success and complication rates of ultrasound-guided renal biopsy at a tertiary care hospital. Materials and Methods: This was a retrospective analysis of 97 ultrasound-guided renal biopsies, all performed by the same radiologist, between 1 March, 2017 and 31 October, 2019. Results: Of the 97 biopsies evaluated, 87 had a definitive pathological diagnosis. In five cases (5.4%), the biopsy results were inconclusive and a second procedure was required. In seven procedures (7.6%), there were complications, all of which were properly resolved. Conclusion: Ultrasound-guided renal biopsy has proven to be a safe, effective method for the diagnosis of nephropathies, with high success rates.

Objective: To assess the technique, efficacy, and safety of computed tomography (CT)-guided percutaneous biopsies of head and neck masses. Materials and Methods: This was a retrospective, single-center study of CT-guided percutaneous core-needle biopsies of head and neck masses. For the analysis of diagnostic accuracy, biopsy results were compared with the final diagnosis, which was determined by histological examination and clinical follow-up. Results: We evaluated 74 biopsies performed in 68 patients. The mean age of the patients was 55.6 years. Most of the lesions (79.7%) were located in the suprahyoid region, and the maximum diameter ranged from 11 mm to 128 mm. The most common approaches were paramaxillary (in 32.4%), retromandibular (in 21.6%), and periorbital (in 14.9%). Five patients (6.8%) developed minor complications. The presence of a complication did not show a statistically significant association with any clinical, radiological, or procedure-related factor. Sufficient material for histological analysis was obtained in all procedures. Thirty-eight biopsies (51.4%) yielded a histological diagnosis of malignancy. There was a false-negative result in three cases (8.3%), and there were no false-positive results. The procedure had a sensitivity of 92.7%, a specificity of 100%, and an accuracy of 96.0%. Conclusion: Our results demonstrate that CT-guided percutaneous core-needle biopsy of head and neck lesions is a safe, effective procedure for obtaining biological material for histological analysis.
