25. Evaluation of TGF-β1 and MCP-1 expression and tubulointerstitial fibrosis in children with Henoch-Schönlein purpura nephritis and IgA nephropathy: A clinical correlation
OBJECTIVES: Henoch-Schönlein purpura nephritis and immunoglobulin A nephropathy are two diseases with similar clinical presentations but very different prognoses. Transforming growth factor β1 and monocyte chemoattractant protein-1 have been associated with the development of tissue fibrosis. We examined the development of tubulointerstitial fibrosis and

26. Clinical features and outcomes of diffuse endocapillary proliferation Henoch-Schönlein purpura nephritis in children
OBJECTIVE: To investigate the outcomes of childhood diffuse endocapillary proliferation Henoch-Schönlein purpura nephritis (DEP-HSPN) in response to early diagnosis and prompt treatment. METHODS: Eleven cases of DEP-HSPN in children were investigated in comparison to HSPN without diffuse endocapillary proliferation (non-DEP-HSPN). RESULTS: DEP-HSPN had a

27. Safety and feasibility of radiofrequency ablation for treatment of Bosniak IV renal cysts
ABSTRACT Purpose To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. Materials and Methods From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. Results All

28. Impact of specimen adequacy on the assessment of renal allograft biopsy specimens
The Banff classification was introduced to achieve uniformity in the assessment of renal allograft biopsies. The primary aim of this study was to evaluate the impact of specimen adequacy on the Banff classification. All renal allograft biopsies obtained between July 2010 and June 2012 for suspicion of acute rejection were included. Pre-biopsy clinical data o

29. Multiple facets of HIV-associated renal disease
HIV infection has a broad spectrum of renal manifestations. This study examined the clinical and histological manifestations of HIV-associated renal disease, and predictors of renal outcomes. Sixty-one (64% male, mean age 45 years) HIV patients were retrospectively evaluated. Clinical presentation and renal histopathology were assessed, as well as CD4 T-cell

31. Single-port retroperitoneal renal biopsy using standard urological instruments
Objective To describe the surgical technique and initial experience with a single-port retroperitoneal renal biopsy (SPRRB). Materials and Methods Between January and April 2013, five children underwent SPRRB in our hospital. A single 1.5 cm incision was performed under the 12th rib at mid-axillary line, and an 11 mm trocar was inserted. A nephroscope was u

32. Accuracy of Percutaneous Core Biopsy in the Diagnosis of Small Renal Masses (≤4.0 cm): A Meta-analysis
Objective To use meta-analysis to determine the accuracy of percutaneous core needle biopsy in the diagnosis of small renal masses (SMRs≤4.0 cm). Materials and Methods Studies were identified by searching PubMed, Embase, and the Cochrane Library database up to March 2013. Two of the authors independently assessed the study quality using QUADAS-2 tool and

33. Issues in solid-organ transplantation in children: translational research from bench to bedside
In this review, we identify important challenges facing physicians responsible for renal and cardiac transplantation in children based on a review of the contemporary medical literature. Regarding pediatric renal transplantation, we discuss the challenge of antibody-mediated rejection, focusing on both acute and chronic antibody-mediated rejection. We review

34. Correlação entre a espectroscopia de fluorescência induzida pelo laser e as alterações histológicas na isquemia e reperfusão renal em ratos / Correlations between the laser-induced fluorescence spectroscopy and histological changes in kidney ischemia and reperfusion in rats.
Introdução: O transplante renal é amplamente reconhecido como a melhor forma de tratamento para os pacientes que necessitam de terapia de substituição renal. Frequentemente a equipe transplantadora se depara com a difícil questão de determinar se órgãos, provenientes de doadores falecidos e limítrofes ou em parada cardíaca, estão aptos para serem

36. Ureteroscopy in patients with coagulopathies is associated with lower stone-free rate and increased risk of clinically significant hematuria
PURPOSE: Patients with coagulopathy are at increased risk of peri-operative hemorrhage. The aim of the present study was to compare ureteroscopy (URS) in these high risk patients to those with normal bleeding profile. MATERIALS AND METHODS: Twelve patients with coagulopathies (Group I) undergoing 17 URS were included in the study [3 for biopsy of ureteral le
