Nephrotic syndrome is a collection of symptoms due to kidney damage. This includes protein in the urine , low blood albumin levels , high blood lipids , and significant swelling . Other symptoms may include weight gain, feeling tired, and foamy urine.
FSGS accounts for 35% of all cases of nephrotic syndrome, making it one of the most common causes of nephrotic syndrome in the United States. [8] FSGS accounts for 2% of all cases of kidney failure. [4] African American patients have four times the likelihood of developing FSGS. Men are about two times as likely to develop FSGS compared to ...
The standard diagnostic workup of suspected kidney disease includes a medical history, physical examination, a urine test, and an ultrasound of the kidneys (renal ultrasonography). An ultrasound is essential in the diagnosis and management of kidney disease. [28]
[5] [6] Risk factors include a family history of chronic kidney disease. [2] Diagnosis is by blood tests to measure the estimated glomerular filtration rate (eGFR), and a urine test to measure albumin. [8] Ultrasound or kidney biopsy may be performed to determine the underlying cause. [5] Several severity-based staging systems are in use. [13] [14]
Video explanation. Author: Tanner Marshall Editor: Rishi Desai, MD, MPH Membranous glomerulonephritis, also known as membranous nephropathy, is where the glomerular basement membrane, or GBM, which lines the glomeruli in the kidney, becomes inflamed and damaged, which results in increased permeability and proteins being able to filter through into the urine, causing nephrotic syndrome.
Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.
Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, [1] but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, [2] in which sense it is distinguished from nephritis, which involves inflammation.
This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia). [8] [10] Signs and symptoms that are consistent with nephritic syndrome include: Hematuria (red blood cells in the urine) [11]
