Introduction: Biopsy is an important diagnostic technique for the treatment of patients with kidney disease. It is possible to make an etiological diagnosis, in addition to determining the prognosis and the probability of response to treatment.
Objective: Determine the main indications and the most frequent histopathological findings in renal biopsies performed in the Department of Adult Nephrology of the Hospital de Clínicas from April 2016 to November 2022.
Methods: Observational, retrospective, cross-sectional study.
Results: 130 biopsies were performed in the period studied, 50.7% in female patients. The main reasons were: nephrotic syndrome 34.6%, systemic lupus ery- thematosus 31.5% and transplant patients with suspected rejection 18.4%. The following most frequent histopathological diagnoses were obtained according to the different indications: focal and segmental glomerulosclerosis-FSGS (24), stage IV lupus nephritis (24) and graft rejection (16), respectively. 0.7% of patients pre- sented nephrectomy as a complication and retroperitoneal hematoma in an equal percentage.
Conclusion: 130 renal biopsies were performed, with no important difference between sexes. The main indications were: nephrotic syndrome, systemic lupus erythematosus and suspected graft rejection, with the most frequent histopathological diagnoses being FSGS, stage IV lupus nephritis and rejection, respectively. Complications occurred in 1.4%.
