Analysis of the renal biopsy database of patients from a nephrology and dialysis center

Renal biopsy is an essential tool for diagnosing many conditions that affect the kidneys. It is the gold standard test for detecting glomerulopathies and parenchymal renal disease and, therefore, helps determine the best treatment for the diagnosed disease.1–4 Percutaneous renal biopsy, commonly performed under ultrasound guidance, is the most commonly used approach, as it is less invasive and can be performed on an outpatient basis. Because of the invasive nature of the procedure, complications are not uncommon. This study aims to analyze the results of biopsies collected at a tertiary referral center in Brazil. We evaluated whether the quality of the tissue sample obtained was sufficient to diagnose the focal lesion and, therefore, establish a diagnosis and treatment for the patient. An epidemiological analysis of the patients undergoing the procedure was also performed, as well as a survey of the main complications related to it.
