Received: Revised: Accepted: March 19, 2012 February 21, 2013 March 11, 2013 Kidney biopsy is a diagnostic technique allowing in vivo collection of kidney tissue material for a histopathological examination, which makes it possible to diagnose disorders in the normal organ structure. The most common biopsy used for a sample collection is oligobiopsy. Renal biopsy is a safe and very useful diagn...

We present the case of a patient with IgG4-related disease, which manifested in an asynchronous manner as vitiligo, cholecystitis, sialadenitis, lymphadenopathy, facial palsy and kidney dysfunction. The patient underwent a renal biopsy, and a presumptive diagnosis of lupus nephritis was made due to compatible clinical and immunological findings. The biopsy revealed IgG4-related kidney disease w...

OBJECTIVES Scarce data exist regarding the effect of acute graft pyelonephritis on kidney histology after a kidney transplant. This study sought to assess the kidney histology at 1 month, and kidney function at 1 year, after acute graft pyelonephritis in kidney transplant patients. MATERIALS AND METHODS All kidney transplant patients with acute graft pyelonephritis between October 2006, and D...

BACKGROUND Chronic lymphocytic leukemia and small lymphocytic lymphoma are 2 different presentations of the most common B-cell neoplasm in western countries (CLL/SLL). In this disease, kidney involvement is usually silent, and is rarely reported in the literature. This study provides a clinicopathological analysis of all-cause kidney disease in CLL/SLL patients. METHODS Fifteen CLL/SLL patien...

To the Editor: The percutaneous renal biopsy is an essential tool in the diagnosis and evaluation of kidney disease. Most renal biopsies are performed under direct ultrasound guidance with automated biopsy needles, techniques that have substantially reduced the risks of the procedure. However, the kidney biopsy still carries a considerable risk of bleeding complications. Although certain risk f...

  Abstract   Pseudoxanthoma elasticum is a rare, hereditary, multisystemic disease affecting   the skin, eye, and cardiovascular system. Renal involvement is uncommon.   We describe two cases of pseudoxanthoma elasticum (PXE) in two women with   distinctive skin lesions and nephrocalcinosis that renal ultrasonography showed a   characteristic pattern of dotted increased echogenicity in the cort...

OBJECTIVES Retrospective study was designed to examine the importance of tissue kidney injury molecule-1 (KIM-1) expression in predicting kidney function in sixty patients (27 males) aged 34.15 ± 12.23 years with different kidney diseases over three years after kidney biopsy. MATERIALS AND METHODS Tissue KIM-1 expression was determined immunohistochemically and KIM-1 staining was scored semiq...

Background Chronic kidney disease is a global health concern, its detection and diagnosis in earlier stages is also a great challenge that can alleviate this burden. Kidney biopsy is important to establish histopathological patterns. But, it is invasive. We aimedto evaluate the correlation of renal resistive index (RI) measured by Doppler ultrasound with the prog...

BACKGROUND The gold standard for investigating the cause of renal graft dysfunction is renal biopsy. However, as this procedure is invasive and has inherent risks, its safety must be established. OBJECTIVE To determine the safety of percutaneous renal biopsy in pediatric orthotopic renal transplantation. METHODS Percutaneous renal biopsies performed on pediatric orthotopic renal transplants...
