Convoluted RBC cast; case of endocarditis-associated crescentic necrotizing glomerulonephritis #UrinarySediment #UrineMicroscopy #PisseProphet #OchsnerNephrology #Glomerular #GN #AKI

The Maltese Cross 🇲🇹🛡️sign is not unique to lipids, other structures can manifest it under polarized light (eg, starch, leucine crystals). Here, a rare sighting of a cast containing suspected ciprofloxacin crystals. #UrinarySediment #UrineMicroscopy #PisseProphet

RBC cast (SM stain, 1000x, BF). Adult with COL4A3 mutation, hematuria, mild proteinuria, normal eGFR. #UrinarySediment #UrineMicroscopy #PisseProphet

Leukocyte (neutrophil) casts can be found in pyelonephritis, interstitial nephritis and glomerulonephritis. But in this case, there’s only one clear possibility. Can you tell? #UrinarySediment #UrineMicroscopy #PisseProphet

RBC casts with fibrous matrix, suspected SLE GN class IV. #UrinarySediment PB stain #UrineMicroscopy #PisseProphet @isgd.bsky.social

7/n back to the bedside, pts present clinically as RPGN or as more subacute versions of AAV. Just this week, we had another case that stimulated this post: note the neutrophil casts and acanthocytes in the #UrinarySediment #PisseProphet

WBC/lipid cast, #UrinarySediment PB-stained. Note that the oval fat bodies did not take up the PB stain and look bright on dark field. PR3-ANCA crescentic necrotizing GN, treatment-naive #UrineMicroscopy #PisseProphet

Snake-like RBC cast with hyaline matrix, #UrinarySediment from a pt with MPO-ANCA crescentic necrotizing GN w/ongoing CYC/RTX-based induction IST (1 month in) #UrineMicroscopy #PisseProphet

Cellular (mixed RBC and WBC) cast with a distinct fibrous matrix, case of crescentic necrotizing pauci immune ANCA GN presenting as RPGN. #UrinarySediment #UrineMicroscopy #PisseProphet

Lipiduria in nephrotic syndrome, a simplistic short overview #PisseProphet #UrinarySediment

Triple phosphate (Struvite) crystals in a “sea” of bacteria (Proteus sp). #UrinarySediment #UrineMicroscopy #PisseProphet

White blood cell (WBC) cast in a #UrinarySediment specimen treated with Prescott-Brodie stain (aka Mohty stain pmc.ncbi.nlm.nih.gov/articles/PMC...). WBC turn blue. Note that phase contrast allows better🔬of the cast matrix. Case of C3 glomerulonephritis. #UrineMicroscopy #PisseProphet

Nephrology rules the world

So I uh sketched on a vintage map 😬.
16 yo son says it looks like I want to fill the entire ocean with urine. 😒🤦🏻‍♀️
