RBC casts – cilindros hemáticos – personal glossaries
The SM was positive in 8. Dysmorphic red blood cells. View forum View forum without registering on UserVoice. Therefore, greater attention should be paid to standardized urinalysis, while new techniques for identification of markers of renal disease are sought.
In addition, the presence of RBC casts in the urine of patients with dysmorphic hematuria is directly associated with a glomerular source for the bleeding; therefore, the finding of a single RBC cast is enough to indicate the glomerular nature of the hematuria.

Several authors have found it difficult to establish a cut-off point to characterize glomerular hematuria. In the s, some studies, such as those by Kohler et al. This study tested the superiority of a urine concentration technique CT over the standard method SM for RBC cast identification in a group of patients suspected of glomerular hematuria.
As reported in other studies, 16 women had a higher general rate of hematuria. The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases. We cannot infer about the existence of glomerulopathies in the study population, but we can certainly state that the CT increases the positivity for RBC casts.
The samples with dysmorphic hematuria were submitted to the two techniques for RBC cast investigation: You can request verification for native languages by completing a simple application that takes only a couple of minutes. An abnormal number of RBCs on urine microscopy is a relatively common finding in laboratory practice, and definition of its origin makes cilindro easier to identify its source in the urinary tract.
CILINDROS HEMATICOS EPUB
Unfortunately, low sensitivity means that a number of cases remain, in which the bleeding source is unknown. Review native language verification applications submitted by your peers. RBC casts Portuguese translation: This study opens new perspectives towards the study of new ways for the urinalysis-based early detection of renal diseases.
Once hematuria is confirmed, investigation of the bleeding source, undertaken with a search for RBC dysmorphism and RBC casts in the urine, is warranted. Comparative analysis of two methodologies for the identification of urinary red blood cell casts.
Assessment of microscopic hematuria in adults. In our case, glomerular lesions justify acute cilindros hematicos failure, but tubular necrosis, given the advanced stage, has possibly played a more important role.
Can J Urol ; Services on Demand Journal.
La presenza di urine concentrate, il pH acido e un basso flusso urinario possono favorire la formazione cilindros hematicos cilindri ialini, riscontrabili, talvolta, anche in individui normali in caso di disidratazione o esercizio fisico intenso.
Automation of urine sediment examination: Of a total of 4, routine urinary samples, with dysmorphic hematuria were selected. The CT, associated with the presence of RBC dysmorphism, was useful to increase the agreement of the two parameters used for identification of glomerular-based bleeding and the diagnosis of glomerular diseases, important causes of chronic kidney disease.
The presence of dysmorphic red blood cells RBCs in the urine is a strong indicator of a glomerular source for the bleeding, being an important tool for the diagnosis of glomerulonephritides.
Participation is free and the site has a strict confidentiality policy. Yet, because the absence of these cells does not rule out the glomeruli as the source of hematuria, these markers have high specificity but low sensitivity.
Hematuria may, therefore, be related to nephrologic or urologic problems. How to cite this article. I cilindri ialini sono chiari e cilindros hematicos, con un basso indice rifrattivo: These factors were excluded by the investigation and selection of samples with dysmorphic RBC.
The urine is concentrated to 1: RBC casts are not frequently visualized in routine urinalysis. Of the samples with hematuria, Close and don’t show again Close. A volte possono essere necessarie particolari colorazioni per distinguere tra globuli bianchi e cellule epiteliali. Clin Chem Lab Med ; The latter were always associated with the presence of other RBC casts, once in isolation they may indicate hemoglobinuria, myoglobinuria or the presence of other similar pigments.
While other methods are not available, we suggest the association of the CT-based RBC cast investigation and the search for RBC dysmorphism for the assessment of renal diseases in the laboratory investigation of the bleeding origin, in patients with confirmed hematuria.
In the following year, Tomita et al. Diagnosis of glomerular haematuria: Red blood cell casts. Routinely, the SM uses a 10 mL aliquot of urine which has undergone 5-minute low-speed centrifugation relative centrifugal force g.
The additional presence of proteinuria, glycosuria and other pathological casts is helpful.
Asymptomatic microhematuria and urologic disease. These data point to the possibility that a myth surrounding cast degeneration by urine centrifugation has been created. The CT was positive in
