Background: Wegener granulomatosis or granulomatosis with polyangiitis is a pauci-immune small vessel vasculitis which is usually associated with anti-neutrophil cytoplasmic antibodies (ANCA) mainly in old men. This small vessel vasculitis is usually characterized by necrotizing granulomatous inflammation with multiorgan involvement. Kidneys could be involved as the main and life-threatening co...

Renal lymphoma as an initial lesion is relatively rare. Bilateral renal lymphoma frequently presents as acute kidney injury. With systematic chemotherapy for the lymphoma, patients usually recover their kidney function. However, in the case we describe here, the patient's kidney function recovered greatly after an open renal biopsy. Here, we review and discuss this unique case.

Introduction: Nephrotic syndrome is a clinical of heavy proteinuria and hypoalbuminemia or hypoproteinemia. Renal biopsy fundamental to assess not only the type but also degree disease activity. The overall prognosis response treatment often depend on severity histological lesions their reversibility.1,2 Case Presentation: An eighteen years old man with nephrotic planned for kidney biopsy. This...

Anticoagulant-related nephropathy (ARN) was initially described in patients on warfarin (as warfarin-related nephropathy) and recently in those using dabigatran. Herein, we report clinical history and kidney biopsy findings in a patient on apixaban (Eliquis). Initiation of treatment with apixaban resulted in aggravation of preexisting mild acute kidney injury (AKI). A few days after apixaban th...

a 3-year-old girl was presented with periorbital edema, hypertension, proteinuria, and hematuria. she recovered clinically after 9 days with normal urinalysis. during the follow-up, she developed recurrent episodes of nephrotic syndrome. the kidney biopsy revealed mild mesangial proliferation and a low dose of prednisolone could effectively control the disease. iran j med sci 2005; 30(1): 38-40...

Results From 27 patients referred to kidney biopsy, only 16 (59.3%) were diagnosed with amyloid kidney disease (AKD), 11 were diagnosed with another nephropathy. The AKD and non amyloid kidney disease (NAKD) groups were comparable on most variables, but showed distinct characteristics with regard to the range of proteinuria (6.46 ±4.3 g vs. 2.4±1.7 g, p= 0.0136), rate of severe FMF (14 vs. 5 pa...

Nephrosclerosis can be defined by the presence of glomerulosclerosis, tubular atrophy, interstitial fibrosis, and arteriosclerosis on renal biopsy. Chronic kidney disease is identified clinically by a reduction in glomerular filtration rate (GFR) and has been characterized histologically by nephrosclerosis. Many relatively healthy older adults have been diagnosed with chronic kidney disease bec...

BACKGROUND Previous studies have examined the spectrum of diseases identified with a kidney biopsy and the complications of the procedure. However, few studies have examined the utility of the test to clarify the diagnosis and guide treatment of pediatric patients. This retrospective, single-center chart review was performed to test the hypothesis that at least 80% of native kidney biopsies pro...

To investigate the possibility that we have been underestimating the true incidence of acute rejection, we began to perform protocol biopsies after kidney transplantation. This analysis looks at the one-week biopsies. Between March 1 and October 1, 1999, 100 adult patients undergoing cadaveric kidney or kidney/pancreas transplantation, or living donor kidney transplantation, underwent 277 biops...
