MULTICENTER STUDY
Jeffrey S Berns, W Charles O'Neill
BACKGROUND AND OBJECTIVES: Some procedures (e.g., placement of temporary hemodialysis catheters and kidney biopsies) are required in nephrology fellowship training. Others (e.g., placement of tunneled hemodialysis catheters, ultrasonography, and hemodialysis access interventions) are not required but are performed at some centers. To assess the procedures performed by nephrologists and nephrology fellows at U.S. adult nephrology training programs and the number of procedures required for fellow competency, a survey was conducted of all such training programs...

REVIEW
Elvira O Gosmanova, Steven Wu, W Charles O'Neill
Ultrasonography plays critical roles in many aspects of nephrology practice. Applications include the evaluation of the kidneys and urinary tract, guidance for the percutaneous kidney biopsy and temporary hemodialysis access placement, and vascular ultrasound of upper extremities related to the permanent hemodialysis access. The simplicity of technique and the limited spectrum of pathological changes coupled with portability, low cost, and safety make sonography the modality of choice for kidney and vascular imaging...

REVIEW
W C O'Neill
Sonography is a critical component of the evaluation of both acute and chronic renal failure; however, most nephrologists have a limited knowledge of this procedure. The acoustic properties, limited spectrum of pathological changes, and ease of visualization of the kidneys, coupled with the safety, simplicity, and low cost of sonography, make it the modality of choice for renal imaging. This review discusses the basics of sonography as they apply to the kidney and describes the findings encountered in the more common causes of renal failure...

K Nass, W C O'Neill
The safety and efficacy of percutaneous biopsy of native kidneys performed entirely by nephrologists at the patient's bedside was evaluated in 101 consecutive patients. The location and depth of the kidney were determined with a portable ultrasound machine, and biopsy was performed with a 15G, automatic, spring-loaded biopsy device without direct ultrasonographic guidance. Renal tissue was obtained in 99 patients, and all samples were adequate for diagnosis, with an average of 33 glomeruli and more than 10 glomeruli in 97%...

COMPARATIVE STUDY
J A Manley, W C O'Neill
The echogenicity of the cortex is an important parameter in interpreting renal sonograms that suggest changes in cortical structure. Echogenicity is currently measured qualitatively, and no attempts have been made at quantification. We developed a method to quantify renal cortical echogenicity in reference to the liver and evaluated its reproducibility, dependence on scanning variables, and potential utility. Sonograms of the right kidney were digitized, and the mean pixel density of regions of the renal cortex and liver was measured and normalized to the gray scale...

REVIEW
W Charles O'neill, Deborah A Baumgarten
Sonography is a simple, inexpensive, and readily available imaging modality that has become an essential component of the management of renal transplantation. It is indicated in almost all patients with acute renal failure and also is useful in the evaluation of pain, infection, and hematuria and the performance of percutaneous biopsy. Although many aspects of sonography are similar in native and transplanted kidneys, there are important differences and problems unique to the renal allograft, which form the basis for this review...

REVIEW
W Charles O'Neill
Ultrasound is commonly used in nephrology for diagnostic studies of the kidneys and lower urinary tract and to guide percutaneous procedures, such as insertion of hemodialysis catheters and kidney biopsy. Nephrologists must, therefore, have a thorough understanding of renal anatomy and the sonographic appearance of normal kidneys and lower urinary tract, and they must be able to recognize common abnormalities. Proper interpretation requires correlation with the clinical scenario. With the advent of affordable, portable scanners, sonography has become a procedure that can be performed by nephrologists, and both training and certification in renal ultrasonography are available...
