PURPOSE We defined the mechanism and cause of pediatric renal trauma, and developed guidelines for management based on the outcome analysis of operative vs nonoperative management. MATERIALS AND METHODS We retrospectively reviewed 374 pediatric renal injuries at San Francisco General Hospital, comparing operative vs nonoperative management based on clinical presentation, type of renal injury,...

PURPOSE Historically, the biopsy of renal masses was not advocated, and to date there remains some controversy on the role of biopsy for renal masses in making treatment decisions. With the widespread use of imaging methods, the incidental diagnosis of renal masses has increased, necessitating renal biopsies to better plan the management of these tumours. Here I review previous reports to defin...

Renal biopsy is an important investigation for suspected renal parenchymal disease and is frequently required in clinical practice. Use of ultrasound and automated spring loaded device has reduced the rate of complications associated with the procedure. However, occasionally dramatic situations of hemodynamic instability arise due to bleeding after renal biopsy. Only four cases of lumbar artery...

UNLABELLED Ultrasound-guided percutaneous renal biopsy is an important technique for diagnosis of glomerular diseases, and the biopsy-induced life-threatening bleeding rarely happens. Primary systemic amyloidosis is a rare disease which may lead to organ dysfunction including arterial stiffness. The accessory renal artery is a kind of renal vascular variation which goes into the renal parenchym...

OBJECTIVE To determine the risk factors for adverse renal outcome in type 2 diabetic patients who underwent renal biopsy and were followed-up longitudinally. RESEARCH DESIGN AND METHODS We examined 68 consecutive patients with type 2 diabetes during the period of 1985-1999 who underwent renal biopsy for proteinuria > or =1 g/day, renal involvement (proteinuria or renal impairment) at the abse...

BACKGROUND AND OBJECTIVES Renal biopsy in acute renal failure of unknown origin provides irreplaceable information for diagnosis, treatment, and prognosis. This study analyzed the frequency and clinicopathologic correlations of renal native biopsied acute renal failure in Spain during the period 1994 through 2006. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Acute renal failure was defined a...

BACKGROUND In the United States, transjugular renal biopsies using the Quickcore side cut needle system have previously been described primarily for transjugular renal biopsy in patients with concurrent liver and kidney disease. METHODS We describe transjugular renal biopsy with the Quickcore trade mark system in 9 patients with nephrotic syndrome and contraindications to percutaneous renal b...

advances in nephrology and pediatric urology have increased the number of children who survive renal disease and become candidates for renal transplantation. ten years of experience in pediatric renal transplantation are reviewed to determine the rates of patient morbidity and graft survival. of the 450 renal transplantations performed in imam reza hospital (1989- 1999), fifty-one were done on ...
