Case of the Week 314

The following images are from a filtered urine specimen in a patient with dysuria.  No further history is available.  Identification?

Schistosomia hematobium

Schistosoma haematobium? The characteristic ova shape and presence in the urine hint at S. haematobium.

Urate crystals

One of the characteristics of parasites is that their ova are fairly uniform in size. The objects pictured did not fit this criterium, furthermore, there is no internal organisation.
The objects would be more compatible with uric acid crystals.

Not a human parasite. I'm not sure if I would agree with uric acid crystal though.

Uric asid crystals.
Too transparent to be identify as Schistosoma haematobium. No sign of miracidium or organelles inside it.

Crystals, thinking Uric Acid...

The standard differential would be S.haematobium or (much more unusual) Dioctophyme renale, however these bodies are not consistent with either and are variable in size and with no specific internal morphology. These appear to be uric acid crystals.

Biochemists might be able to present a more thorough analysis of what the presence of a high number of uric acid crystals in fresh urine indicates, however that is out of my skill set!

Yup size is not consistent, and highly variable and internal structures appear to be more crystalline.
Not parasitic :)
