Jan 1, 2018 · Dysmorphic urinary RBCs have been regarded as an indicator of glomerular pathology, 7 and dysmorphic RBCs in urinary sediment (Figure 2) are also considered to represent renal pathology. On electron microscopy, the glomerular basement membrane is usually 300 to 400 nm wide, whereas the diameter of the red blood cell is 7 μm.

Oct 26, 2023 · Much more commonly, the diagnosis relies on the presence of dysmorphic, or glomerular-type, RBCs in the urine. Their presence can help avoid unnecessary urological procedures, may alert the clinician to the presence of glomerular injury, and is instrumental in the care of patients with kidney diseases.

Jan 11, 2017 · To resolve these problems, we first tested a modified urinalysis protocol with an increased relative centrifuge force and concentration factor in 20 biopsy-confirmed glomerulonephritis patients...

Jul 14, 2020 · Urine acanthocytes are a distinct type of dysmorphic erythrocytes that can be found during microscopic examination of the urinary sediment. Their unique characteristics make them rather pathognomonic of hematuria that originates from a glomerular disease, i.e., glomerular hematuria (Figure 1).

Dysmorphic erythrocytes are found in the urine of patients with glomerular bleeding, whereas isomorphic erythrocytes characterize nonglomerular or urological hematuria. Urine specimens from 100 patients with microscopic hematuria were collected …

abnormalities in the shape of red cells in the urine (dysmorphism) is gaining popularity in nephrology. However, there is uncertainty in the literature regarding both the number of red blood cells (RBC) in normal urine, as well as the quantification of dysmorphism. We have shown that in normal urine (N = 27) the number of RBC is less than 2,000/mI

Oct 6, 2017 · Dysmorphic red blood cells (dRBCs) on urine microscopy have been associated with glomerulonephritis (GN). We assessed the prevalence and ability of dRBCs to differentiate GN from other kidney diseases.

Urinalysis was positive for proteinuria and hematuria, and urinary sediment analysis showed dysmorphic red blood cells (RBCs) and red cell casts, leading to a diagnosis of glomer-ulonephritis. She had proteinuria of 1.2 g/24 hours. Laboratory tests for …

Feb 18, 2022 · We’re all taught that looking for dysmorphic red blood cells on urinalysis is a useful marker of glomerular hematuria. But how do we define “dysmorphic”? And how was this association originally studied? One landmark paper was this 1991 study in …

Mar 1, 1990 · Scanning electron microscopy of the urine specimens showed a marked difference in morphology between dysmorphic and isomorphic red blood cells. This differentiation can be made with a simpler instrument, the standard Coulter counter.
