Biopsy of small kidneys: A safe and a useful guide to potentially treatable kidney disease.

Over the past four years, all patients with unexplained rapid progression of their renal disease were subjected to kidney biopsy, despite their small size (<9 cm), to define its etiology. Children, pregnant women, morbidly obese patients, and those with an unstable cardiovascular state, septicemia, bleeding diathesis as well as those kidney size with size <6 cm were excluded from the study. Doppler ultrasound was used to exclude renovascular/ischemic nephropathy.

Hilar and para-aortic necrotizing lymphadenopathy associated with antineutrophil cytoplasmic antibody-negative pauci-immune crescentic glomerulonephritis.

Lymph node involvement as a part of systemic vasculitis is rare. We report a case of women with rapidly progressive renal disease associated with recurrent epigastric pain, weight loss, and massive hilar as well as para-aortic lymphadenopathy. Ultrasound-guided biopsy of her scarred kidneys revealed antineutrophil cytoplasmic antibody-negative crescentic glomerulonephritis and that of lymph nodes showed severe necrotizing vasculitis.

Renal ablation using bilateral renal artery embolization for treatment of resistant nephrotic syndrome.

An 18-year-old man presented with severe nephrotic syndrome due to focal segmental glomerulosclerosis. His disease failed to remit with corticosteroids, calcineurin inhibitors, mycophenolate and rituximab. As his disease progressed with time, his anasarca became more resistant to high-dose combination diuretics and he developed multiple life-threatening bacterial infections.

Percutaneous alcohol sclerotherapy of a hepatic hydatid cyst after balloon occlusion of a large biliary communication.

Objective: To present a case of hepatic hydatid cyst with a biliary communication that was not suitable for surgery and hence necessitated sclerotherapy with absolute alcohol after occluding the biliary communication with a balloon catheter.

Clinical Presentation And Intervention: A 50-year-old Asian man presented to the surgical emergency department with a 1-year history of repeated attacks of obstructive jaundice and right hypochondrial pain. Ultrasound and contrast computed tomography revealed a cyst, and endoscopic retrograde cholangiopancreatography and cystography revealed a biliocystic communication.
