💦 Urinary sediment: leukocytes, some macrophages, and triple phosphate crystals. No RBC

Urine culture pending

5/n RBC casts were also found #UrineMicroscopy

WBC cast with numerous "glitter cells" - phase contrast - from patient with suspected acute interstitial nephritis - #UrineMicroscopy #UrinarySediment

#UrinarySediment from a pt with #AKI #RPGN due to suspected MPO-AAV-GN inspected with Sternheimer stain: WBC cast (bright field), broad RBC cast (bright), waxy cast (bright), and granular cast w/Ca Oxalate monohydrate crystals (oblique). #OchsnerNephrology #UrineMicroscopy

Mixed cellular casts - brightfield with SM stain - #UrinarySediment #UrineMicroscopy

4. The meeting: the agenda included presentations tailored to standardization of urinalysis from the laboratory medicine perspective as well as some with clinical context. On day 2, I was asked to present on nephrologist’s approach to #UrineMicroscopy

Bilirubin crystals under polarized light #UrineMicroscopy #UrinarySediment

#UrinarySediment
16yo female, admitted with hematuria and RPGN (Creat 0.7 > 4mg/dL),
#UrineMicroscopy showed RBC cast, acanthocytes.

#UrinarySediment
46yo male, with necrotizing scleritis and c-ANCA vasculitis.
#UrineMicroscopy showed RBC cast, mixed casts (leucocytes + RBC + lipids), acanthocytes

After a fun and productive #KidneyWk, I’m right back in ✈️ mode again, this time heading to Santiago to share and learn more within the #UrinarySediment #UrineMicroscopy South American Lab/Pathol/Nephrol community 🇵🇪🇨🇱

Glitter cells

Glitter cells
WBC’s exhibiting granular motility may be called “glitter cells”, Sternheimer-Malbin cells”, or “granular motility cells”. Although they were once thought to be pathognomonic for pyelonephritis they are a non specific finding

🔬for the diagnosis of glowmrulonephritis, searching for urinary acanthocytes only using bright field illumination is clearly suboptimal compared to utilizing dark field illumination or phase contrast microscopy. #UrinarySediment #UrineMicroscopy karger.com/gdz/article/...

Mixed cellular containing RBCs, WBCs (blue) and RTECs (fuchsia) in the #UrinarySediment from a patient with suspected IgA nephropathy 🔬bright field (500x) and oblique illumination (1000x) #UrineMicroscopy #OchsnerNephrology

In this picture, we were unsure if it was a red blood cell cast or a red blood cell cluster due to its shape. What do you think?

Mixed cellular cast (RBC’s and WBC’s, and a few tubular epithelial cells) - note the WBC’s are clearly indicated by Prescott-Brody stain whereas the tubular cells are not - in preserved urine sample from a case of GPA, stored at room temperature for 2.5 years! #UrineMicroscopy #UrinarySediment

RBC cast - brightfield, unstained - in preserved urine sample from a case of GPA, stored at room temperature for 2.5 years! #UrineMicroscopy #UrinarySediment

Oval fat body and acanthocyte - brightfield with SM stain - in preserved urine sample from a case of GPA, stored at room temperature for 2.5 years! #UrineMicroscopy #UrinarySediment

When asked by a denier about what proof I have that #UrineMicroscopy makes a difference (often w/a “I’ve been practicing 30 yrs without it”), my answer is that one cannot grasp the full extent of missed information by ignoring a tool when there’s lack of proficiency on how to properly use the tool
