Greft sağkalımını etkileyen faktörlerin transplant böbrek biyopsileriyle değerlendirilmesi

Amaç: Uzun dönemdeki surviye ve allograft fonksiyonuna etkili olan faktörler her merkezde farklılıklar gösterebilmektedir. Bu nedenle ünitemizden takipli renal allograft biyopsi yapılmış olan hastaların biyopsi sonuçları ve greft sağ kalımları arasındaki ilişkilerin değerlendirilmesi amaçlanmıştır. Yöntemler: 70 hastaya yapılan 94 adet biyopsi retrospektif olarak incelemiştir. Ultrason rehberliğinde tek kullanımlık 16G otomatik iğne ile 2 kore biyopsi alınmıştır. Her biyopsi ışık mikroskopisi ve immunfloresan boyama ile incelenmiştir. Hastalar akut selüler rejeksiyon (ASR), kalsinörin inhibitörü(KNI) toksisitesi, intersitisyel fibrozis tübüler atrofi (IFTA), akut tubüler hasar(ATH) ve greft kaybı gelişenler olarak gruplara ayrılarak alt analizleri yapılmıştır. Bulgular: Toplamda 34(%36,2) biyopsi ile en sık tespit edilen patolojiyi akut selüler rejeksiyon oluşturmaktadır. IFTA, ATH, nüks/de novo glomerülonefrit biyopsi sayıları sırasıyla 21(%22,3), 20(%21,3), 15(%16) olarak bulunmuştur. Akut rejeksiyon öyküsü olanlarda greft sürvisinin daha kısa olduğu tespit edilmiştir (p

Evaluation of factors influencing graft survival by transplant kidney biopsies

Objective: Factors affecting long-term survival and allograft function may differ in each center. Therefore, it is aimed to evaluate the relation between biopsy results and graft survival of patients who have undergone renal allograft biopsy. Methods: We retrospectively analyzed 94 biopsies of 70 renal transplant recipients. Disposable 16 G needles were used to perform 2 ultrasound-guided core biopsies. Each specimen was examined under light and mmunofluorescence microscopy. Patients were divided into acute cellular rejection (ACR), calcineurin inhibitor (CNI) toxicity, graft loss, interstitial fibrosis tubular atrophy (IFTA), acute tubular damage (ATD) groups and analyzed. Results: The most frequent pathology was ACR, diagnosed in total of 34 (36.2%) specimens. IFTA, ATD and recurrent de novo glomerulonephritis biopsy were 21 (22.3%), 20 (21.3%) and 15 (16%), in number, respectively. Graft survival in patients with a history of acute rejection was shorter than without history (p
