Evaluación de la función renal más allá del laboratorio: rol y desarrollo actual de la imagenología renal

Rev. méd. Chile; 151 (8), 2023
La evaluación de la función renal se realiza habitualmente a través de la estimación de la tasa de filtración glomerular y el análisis de la orina. La evaluación morfológica renal a través de una imagen permite complementar esta información. Sin embargo, muchas de las aplicaciones de las técni...

Sensibilidad y especificidad de la presión de pulso ampliada como prueba diagnóstica de IRC estadio K/DOQI III-b

Gac. méd. Méx; 156 (5), 2020
Resumen Introducción: La presión de pulso ampliada (PPA) se asocia a un filtrado glomerular calculado ≤ 60/mL/minuto/1.73 m2, por lo que puede ser útil como prueba diagnóstica para identificar a personas con insuficiencia renal crónica (IRC) estadio K/DOQI III-b. Objetivo: Determinar la util...

Usefulness of Kidney Donor Profile Index (KDPI) to predict graft survival in a South Brazilian Cohort

J. bras. nefrol; 42 (2), 2020
Abstract Introduction: Kidney Donor Profile Index (KDPI) has been incorporated in the United States to improve the kidney transplant allocation system. Objectives: To evaluate deceased kidney donors' profile using KDPI and compare to the previous United Network for Organ Sharing (UNOS) definition of ex...

Rare inherited kidney diseases: an evolving field in Nephrology

J. bras. nefrol; 42 (2), 2020
Abstract There are more than 150 different rare genetic kidney diseases. They can be classified according to diagnostic findings as (i) disorders of growth and structure, (ii) glomerular diseases, (iii) tubular, and (iv) metabolic diseases. In recent years, there has been a shift of paradigm in this fiel...

Kidney transplantation with donors in severe acute kidney injury. Should we use these organs? Retrospective Case Series

J. bras. nefrol; 41 (4), 2019
ABSTRACT Introduction: The number of incident and prevalent patients on dialysis has increased, as well as the number of candidates for renal transplantation in Brazil, without a proportional increase in the number of organ donors. The use of expanded kidneys, as to renal function, may be an alternative...

Hepatitis C in Hemodialysis Units: diagnosis and therapeutic approach

J. bras. nefrol; 41 (4), 2019
Abstract According to data from the last census of the Brazilian Society of Nephrology (SBN), the prevalence of hepatitis C virus (HCV) in Brazilian hemodialysis units (HU) is 3.3%, about three times higher than what is reported for the Brazilian general population. Often, professionals working in HU are...

Zinc alpha 2 glycoprotein as an early biomarker of diabetic nephropathy in patients with type 2 diabetes mellitus

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: Although microalbuminuria remains the gold standard for early detection of diabetic nephropathy (DN), it is not a sufficiently accurate predictor of DN risk. Thus, new biomarkers that would help to predict DN risk earlier and possibly prevent the occurrence of end-stage kidney dis...

The natural history of solitary post-nephrectomy kidney in a pediatric population

Int. braz. j. urol; 45 (6), 2019
ABSTRACT Introduction: Children with a solitary post-nephrectomy kidney (SNK) are at potential risk of developing kidney disease later in life. In response to the global decline in the number of nephrons, adaptive mechanisms lead to renal injury. The aim of this study was to determine the prevalence and...

Reserva funcional renal: concepto y aplicabilidad potencial en la práctica clínica

Rev. méd. Chile; 147 (10), 2019
Renal functional reserve (RFR) is the capacity of the kidney to increase its glomerular filtration rate (GFR) in response to physiological or pathological stimuli. The most commonly used stimuli to assess this reserve are an oral load of proteins of animal origin, amino acid infusions, dopamine, glucagon...

Preoperative proteinuria is associated with increased rates of acute kidney injury after partial nephrectomy

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Purpose We investigated the association between preoperative proteinuria and early postoperative renal function after robotic partial nephrectomy (RPN). Patients and Methods We retrospectively reviewed 1121 consecutive RPN cases at a single academic center from 2006 to 2016. Patients without...
