Clinicopathological evaluation of our patients with ultrasound assisted percutaneous kidney biopsy

Abstract

Aim: This study aims to determine the frequency of kidney diseases based on histological diagnosis and to evaluate the relationship between clinical and histopathological findings in patients undergoing percutaneous kidney biopsy for various indications. Material and Method: In this cross-sectional study, demographic, anthropometric and laboratory data of the patients were obtained retrospectively from medical files and computer records. Biopsy indications and histopathological diagnoses (primary glomerular diseases, secondary glomerular diseases, tubulointerstitial diseases and other causes) of the patients were examined. Results: Of 103 patients, 57 (55.3%) were male and 46 (44.7%) were female. The mean age of the patients was 44.67±15.29 years. The most common biopsy indication was hematuria+proteinuria+renal dysfunction (n=28, 27.2%). The most common pathology in histopathological diagnoses was primary glomerular diseases (56.3%), the most common diagnosis was IgAN (n=16, 15.5%). Tubulointerstitial diseases were seen more frequently in the 60 years and older group. (n=4, 25%). The most common cause of secondary glomerulonephritis was AA amyloidosis. The number of tubular disorders increased with advanced age. Conclusion: In our center, renal biopsy was performed most frequently with the combination of proteinuria, hematuria, and renal dysfunction. The most common histopathological result was primary glomerulonephritis, in which IgAN took the first place.
