One of many shapes of urinary uric acid crystal, a dihydrate form. Contaminating fiber over it. #UrinarySediment #Crystalluria #UrineMicroscopy
Calcium phosphate “plates” or “continents”, 4x objective, SM stain, bright field, polarized light; acute hyperphosphatemia, AKI, ATN, DKA, shock. #UrinarySediment #UrineMicroscopy @OchsnerNephro @karolas_smile #crystalluria
When URINE a mood for a good day at work, ready to debate POLARIZED opinions. Showing off a generous gift from @jrseltzer during #KidneyWk #UrinarySediment #crystalluria 🔬
More classic diamond-shaped uric acid crystals, same preserved specimen 4 weeks later. #UrinarySediment #UrineMicroscopy #Crystalluria @OchsnerNephro
One of those days when you find a uric acid crystal with your last name initial 😏 🔬#UrinarySediment #crystalluria
Cluster of uric acid crystals. Eye-catching, yet of not known clinical significance #UrinarySediment #crystalluria AKI
1/2 Example to illustrate the importance of various steps in #UrineMicroscopy. First image at 100x, not much recognizable. At 400x, CaOx dihydrate crystals are noted, better appreciated with partial dark field polarization and oblique illumination #crystalluria

2/3 exhibit B: calcium oxalate monohydrate and dihydrate crystals in the #UrinarySediment #crystalluria #UrineMicroscopy @weddellite
Struvite (MgNH4PO4.6H20, triple phosphate) crystal surrounded by numerous urea-splitting bacteria, nitrite (bright pink) positive, pyuria, alkaline pH. #UrinarySediment #UrineMicroscopy #crystalluria
Waxy appearing material under bright field illumination displaying a red orange signal under polarized light, highly suspicious for ciprofloxacin crystal #UrinarySediment #UrineMicroscopy #AKI #crystalluria
Ciprofloxacin crystals under polarized light #UrinarySediment #AKI #crystalluria #UrineMicroscopy
Calcium oxalate monohydrate crystals, AKI of unknown cause, work up in progress #UrinarySediment #UrineMicroscopy #crystalluria #PisseProphet
Cast w/several crystalline structures, dark oval ones likely ciprofloxacin, top right a leucine-like crystal (hepatopathy present). Smaller crystals resemble CaOx monohydrate but cipro itself may crystallize that way too #UrinarySediment #crystalluria @jrseltzer @JoseTesser
1/5 #UrineMicroscopy in a case of AKI. A cast is identified and appears to be of granular/waxy nature. However, particles within the cast stood out under polarized light. #crystalluria
Rare sight of a leucine crystal under polarized light mimicking a PET CT renogram. At least that’s what I see 😏 #UrinarySediment in a pt with AKI and cirrhosis. @HrsHarmony #crystalluria @OchsnerNephro @OchsnerIMRes
Cluster of bilirubin crystals forming a pseudocast. #UrinarySediment inspected under bright field and polarized light microscopy. T Bili 40. No casts seen. Prerenal #AKI in #cirrhosis @OchsnerNephro @HrsHarmony #UrineMicroscopy #crystalluria
Not every #AKI in cirrhosis is plain hepatorenal. Leucine crystals, scattered amorphous material and a few granular casts captured most of the attention. But, careful inspection reveals acanthocytes; GN suspected. #HRS #UrinarySediment #UrineMicroscopy @HrsHarmony #crystalluria
Serum uric 14 mg/dL, WBC 44k, #AKI. #UrinarySediment inspected with bright field illumination under polarized lights revealed abundant uric acid crystals. Tumor lysis syndrome suspected. #PisseProphet #crystalluria @OchsnerNephro #nephropic
3/Sternheimer-Malbin stained-specimen is prepared to further characterize cellular casts. Now cell nuclei appeared more noticeable. #UrinarySediment #crystalluria
Struvite (triple phosphate) crystals found incidentally in a pt with #AKI, brightfield and polarized light. Urine culture then showed Enterococcus faecium. #UrinarySediment #PisseProphet #crystalluria #UrineMicroscopy
#AKI in cirrhosis, possible #hepatorenal. Scattered bili-stained granular casts, unusual number of leucine crystals within casts and isolated, in a background of hematuria #UrinarySediment #urinemicroscopy #PisseProphet #crystalluria

Unusual catch of a “dumbbell” Ca oxalate crystal and fat droplets that appear to be within a semi-waxy SM-stained cast. Pt w/SLE GN V. #UrinarySediment #urinemicroscopy #pisseprophet #crystalluria @weddellite
