Abstract

Objective: Acute kidney injury (AKI) occurs in various conditions with different clinical presentations. Kidney biopsy (KB) is recommended when pre-renal and post-renal causes have been excluded, and the cause of AKI is unclear. We aimed to determine the histopathological features in patients with AKI and compare the frequency of the underlying causes in patients with different age groups. Methods: This retrospective study was performed on all patients who underwent KB for AKI at our institution between January 2006 and April 2021. Demographic, clinical, and laboratory data and histopathological results were retrieved from the patients’ files. Patients aged 60 years and older were regarded as elderly. The distribution of renal diseases was compared between the age groups. Results: Overall, 767 kidney biopsies were performed at our institution for 15 years. Of these, 171 (22.2%) had unexplained AKI, of whom 35% were elderly. Males were predominated in both groups. The most common diagnosis was glomerular diseases (71.9%), followed by tubulointerstitial diseases (21.7%) and vascular lesions (5.3%). Immunoglobulin A nephropathy was the most frequent diagnosis in adults, whereas pauci-immune glomerulonephritis was the most frequent cause of AKI in the elderly. Conclusion: Our data documents the different patterns of biopsy-confirmed causes of AKI according to the age groups and points the value of biopsy since most of the pathologic diagnoses are entities that are both difficult to diagnose without biopsy and are treatable.

Özet

Amaç: Akut böbrek hasarı (ABH), farklı klinik bulgular ve farklı nedenler ile ortaya çıkabilir. ABH’ye yol açabilecek prerenal ve postrenal nedenler dışlandığında ve ABH’nin nedeni saptanamadığında böbrek biyopsisi (BB) önerilir. Bu çalışmada, ABH ile başvuran hastalarda histopatolojik özelliklerin belirlenmesi ve farklı yaş gruplarındaki hastalarda altta yatan nedenlerin sıklığının karşılaştırılması amaçlandı. Gereç ve Yöntem: Ocak 2006 ve Nisan 2021 tarihleri arasında ABH nedeniyle BB yaptığımız tüm hastalar geriye dönük olarak tarandı. Demografik, klinik ve laboratuvar verileri ile histopatolojik sonuçlar hasta dosyalarından kaydedildi. Altmış yaş ve üzeri hastalar yaşlı olarak kabul edildi. Böbrek hastalıklarının dağılımı yaş grupları arasında karşılaştırıldı. Bulgular: On beş yılda yapılan 767 BB değerlendirildi. Yüz yetmiş birinde (%22,2) açıklanamayan ABH vardı ve bunların %35’i yaşlıydı. Her iki grupta da erkekler baskındı. En sık tanı glomerüler hastalıklar (%71,9) iken, bunu tubulointerstisyel hastalıklar (%21,7) ve vasküler lezyonlar (%5,3) izledi. Erişkinlerde en sık karşılaşılan patolojik tanı immünoglobulin A nefropatisi iken yaşlılarda pauci-immün glomerulonefrit idi. Sonuç: Verilerimiz; ABH’de BB sonuçlarının yaşa göre değiştiğini ve BB tanı ve tedavinin yönlendirilmesindeki değerini göstermektedir.
