Item Efficacy of the Sonoelastography Method for Diagnosis of Fibrosis in Renal Transplant Patients(2022) Soudmand, Arash; Ozturk, Funda Ulu; Uslu, Nihal; Haberal, Nihan; Boyvat, Fatih; Moray, Gokhan; Haberal, Mehmet; https://orcid.org/0000-0002-3462-7632; 29993356; AAJ-8097-2021Objectives: Although biopsy is the most important method for diagnosing the cause of renal allograft dysfunction, sonoelastography, a new ultrasonography method, can be used to distinguish between the soft or hard nature of lesions. In this study, our aim was to investigate whether sonoelastography could diagnose fibrosis in renal transplant patients. Materials and Methods: In this prospective study, we included patients over 18 years old who were recommended for clinical biopsy. Sonoelastographic evaluation was made by conducting acoustic radiation force impulse measurements for each patient after they were admitted to the clinic for biopsy. Measurements were performed just before the biopsy procedure. All results were examined by 2 experienced radiologists using the Siemens S3000 Ultrasound Machine (Erlangen, Germany). Comparisons of ultrasonographic values with biopsy results were made with SPSS software (SPSS: An IBM Company, version 20, IBM Corporation, Armonk, NY, USA). Results: Of the 65 patients included in this study, pathology showed acute T-cell-mediated rejection in 37 patients. There was a significant correlation between the pathologic Banff scores and the sonographic acoustic radiation force impulse values (P = .002), where the degree of Banff increased as the mean acoustic radiation force impulse values elevated. A rise in mean impulse values correlated with increased degree of interstitial fibrosis in renal allografts. Renal parenchymal echogenicity of patients significantly differed by sex (P = .009), with an average renal echogenicity of grade 1 in women and grade 0 in men. Also, a statistically significant difference was found between age of the renal transplant recipient and resistive index values. Conclusions: Our study showed a significant correlation between Banff degree and the acoustic radiation force impulse values of renal transplant patients. In addition to biopsy, sonoelastography can be beneficial for the diagnosis of fibrosis in renal transplant patients.Item 17 Years Of Pediatric Liver Transplantation Experience For Cirrhosis And Hepatocellular Carcinoma(2022) Ozcay, Figen; Sezer, Oya Balci; Sarialioglu, Faik; Boyvat, Fatih; Coskun, Mehmet; Reyhan, Nihan Haberal; Haberal, Mehmet; https://orcid.org/0000-0002-3462-7632; AAJ-8097-2021Item Liver Transplant Experiences For The Budd-Chiarı Syndrome At Baskent University Transplant Centers(2021) Karakaya, Emre; Akdur, Aydincan; Soy, Ebru H.
