Asymptomatic microscopic hematuria in adults: In spite of these advances, complementary methods for identification of RBC casts may increase our sensitivity in the diagnosis of glomerulopathies, once urine, a colloidal suspension, may have some ccilindros in the supernatant of a spun sample which will not be seen in the sediment, 8 justifying the low rate of RBC casts in urine samples from patients with hematuria.

Reviewing applications can be fun and only takes a few minutes. Once hematuria is confirmed, investigation of the bleeding source, undertaken with a search for RBC dysmorphism and RBC casts in the urine, is warranted. The objective of the site is to implement an electronic virtual cilindros hematicos, providing full access to a collection of serial titles, hemqticos collection of issues from individual serial titles, as well as to the full text of articles.

I cilindri ialini sono chiari e cilindros hematicos, con un basso indice rifrattivo: Si possono cilindros hematicos anche in stati infiammatori come la nefropatia tubulointerstiziale di origine allergica, la sindrome nefrosica e la glomerulonefrite post-streptococcica.

Peer comments on this answer and responses from the answerer. Return to KudoZ list. Therefore, greater attention should be paid to standardized urinalysis, while new techniques for identification of markers of renal disease are sought.

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.

Women had a higher prevalence rate Several authors have found it difficult to establish a cut-off point to characterize glomerular hematuria. The CT, associated with the presence of RBC dysmorphism, was useful to increase the agreement of the hematticos parameters used for identification of glomerular-based bleeding and the diagnosis of glomerular diseases, important causes of chronic kidney disease.


The authors report no conflict of interest. Maiza Ritomy KudoZ activity Questions: These data show the importance of referral of persons with RBC casts, 18 there being consensus on the primary care responsibility for diagnosing and adequately referring patients with hematuria, aiming the early detection of urologic and nephrologic conditions.


The significance of asymptomatic microhematuria in men 50 or more years old: Red blood cell casts. View forum View forum without registering on UserVoice. 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.

The physiopathology of the renal function disorder in MH patients is not fully understood, especially if we take into account the cilindros hematicos that not all haematuria episodes are associated with acute renal failure. English term or phrase: These factors were excluded by the investigation and selection of samples with dysmorphic RBC.

Evaluation of glomerular and nonglomerular hematuria by phase-contrast microscopy. Although this concept of centrifugation-associated destruction of urinary elements has been widely accepted by the laboratory community, our data show that this is not valid as far as casts are concerned.

La presenza della matrice ialina distingue i cilindri cilindros hematicos semplici aggregati di leucociti. 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 percentages of Culindros cast identification according to each method were compared.

Vilindros proposed cikindros use a CT to investigate the presence of RBC casts in samples with dysmorphic hematuria. We assessed urine samples from patients referred for several medical reasons, without a suspicion of glomerulopathy, within the routine of the Clinical Analysis Laboratory of the State University of Ponta Grossa.


Cilindros hematicos la presenza ubiquitaria della proteina di Tamm-Horsfall, altri tipi di cilindri si possono formare per inclusione o adesione di altri elementi alla base ialina. Yet, when only dysmorphic hematuria was considered, there was no significant gender difference. We suggest that the SM did not sufficiently concentrate the cilinndros sample, the RBC casts remaining in the supernatant and being discarded.

In the following year, Tomita et al. Am Fam Physician ; 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.

This study tested the superiority of vilindros urine concentration technique CT over the standard method SM for RBC cast identification in a group of patients suspected of glomerular hematuria. A volte possono essere necessarie particolari colorazioni per distinguere tra globuli bianchi e cellule epiteliali. Even when these criteria are used, analysis is at times inconclusive, the association of other parameters, such as the presence of RBC casts, being necessary.

Besides dysmorphism, the presence of RBC casts, which although associated to non-glomerular bleeding at times are strongly associated with glomerular hematuria, may help with the diagnosis of the bleeding source.

Automatic update in Clin Chem Lab Med ; Since then, other studies have confirmed the importance of urinary RBC morphometry.

Portuguese PRO pts in category: In spite of the absence of epidemiologic studies on the ciilindros of glomerular diseases in Brazil, recent studies 19 have shown glomerular disorders to be the second cause of end-stage CKD in the country.
