ABSTRACT

The high rate of compatibility between the histopathological diagnosis and our preliminary diagnoses should not question the necessity of pathological evaluation, and even all kinds of examinations should be used to reach the most accurate diagnosis with the contribution of genetic studies.

Of 126 patients who underwent kidney biopsy, 62 (49.2%) were male; 64 (50.8%) were girls; mean age was 9.5±4.1 years. The most common biopsy indication was nephrotic syndrome (32.5%). Immunoglobulin A nephropathy (IgAN) was the most common histopathological diagnosis (23%). The concordance between clinical preliminary diagnosis and histopathological diagnosis was as high as 82.6%.

In our study, the files and biopsy results (a total of 134 biopsy results) of 126 pediatric patients aged 1-17 years who were followed up in our Pediatric Nephrology clinic and underwent percutaneous kidney biopsy between 2011 and 2021 were evaluated retrospectively. All patients’ age, gender, biopsy adequacy, compliance with the indication and histopathological diagnosis, and follow-up status were recorded.

Our aim in this study is to evaluate the data of native and transplant kidney biopsies in our tertiary pediatric nephrology center in terms of demographics and clinico-pathology, to determine biopsy indications and to evaluate the compatibility of indication and histopathological diagnosis.
