Percutaneous renal biopsy is an important tool for defining the type and severity of many renal diseases. Modifications in the procedure have been made from time to time. The latest innovation has focused on more accurate localization of the kidney by ultrasound localization prior to biopsy. From a large series published in the literature it appears that renal biopsy is almost without risk. How...

There are many clinical situations in which physicians may be uncertain whether to refer a patient to a nephrologist for renal biopsy. Biopsy is often necessary in unexplained acute renal failure (ARF) and in nephrotic syndrome (Table 1). This article addresses the more difficult question of when renal biopsy may be indicated in suspected chronic renal disease. Renal biopsy should be performed ...

The aim of this study was to define normal ranges of histological features in pediatric muscle in comparison with muscle demonstrating inflammatory changes. Sixteen pediatric muscle biopsy samples, considered normal by standard histology, were analyzed for the presence of inflammatory cells, and the expression of neonatal myosin and major histocompatibility complex (MHC) Class 1. Normal finding...

Renal biopsy in the dog, described as the Iaparotomy and keyhole technique [7], is an effective method for the evaluation of dogs with renal disease [8]. For getting a reliable diagnosis and keeping the dog safe, selective renal biopsy with an adaptive need]e was required [6, 11]. Recently, ultrasound (US)-guided renal biopsy in the large-sized ogs [2, 3] and human beings [5, 11, 12] have been ...

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 don...

BACKGROUND Renal involvement is rare in primary Sjögren syndrome (PSS). In this study, we examined renal biopsy findings in patients with PSS and correlated them with their clinical and renal findings. METHODS Twenty-five patients with PSS who underwent renal biopsies from two renal units in Scotland between 1978 and 2013 were identified from renal biopsy database. We examined the renal morph...

BACKGROUND The use of percutaneous needle biopsy in the evaluation of indeterminate renal masses is controversial and its role in management remains largely unclear. We set to establish current practice on this issue in UK urology departments. METHODS We conducted a national questionnaire survey of all consultant urologists in the UK, to establish current practice and attitudes towards percut...

OBJECTIVE To study the diagnostic yield of specimen obtained by percutaneous renal biopsy (PRB) under CT guidance and Ultrasound (US) guidance. METHODS This study was conducted at the department of Nephrology at Liaquat National Hospital and Dr. Ziauddin Hospital, Karachi. Renal biopsy specimens obtained between January 2007 and September 2009 were studied for number of glomeruli obtained. In...
