(Urine Sediment Analysis) Pemeriksaan Sediment Urin • Struvite crystals are the most common type in urine from dogs and cats. They are often seen in urine from clinically normal individuals. Though they can be found in urine of any pH, their formation is favored in neutral to alkaline urine. Urinary tract infection with urease-positive bacteria can promote struvite crystalluria (and urolithiasis) by raising urine pH and increasing free ammonia. SDU-DK-1107
(Urine Sediment Analysis) • Cylindrical bilirubin crystals have formed in association with droplets of fat, resulting in a "flashlight" appearance. This form is less commonly seen. Bilirubin crystals are seen most commonly in canine urine, especially in highly concentrated specimens. They are less common in urine of other species. In dogs, they often are of no significance (healthy dogs can have low, but detectable, bilirubin levels in urine). SDU-DK-1107
Bilirubin crystals (or positive chemical reaction on the urine dipstick) in feline, equine, or bovine urine should be investigated since an underlying Bilirubin crystals (Urine Sediment Analysis) cholestatic process is likely. SDU-DK-1107
(Urine Sediment Analysis) Calcium Carbonate SDU-DK-1107
Amorph crystals (Urine Sediment Analysis) Calcium oxalate dihydrate crystals sometimes also can present as "amorphous" when the individual crystals are very small. Examination at higher magnification will reveal the typical "envelope" appearance. Xanthine crystals are usually in the form of "amorphous" crystals. These crystals occur in Dalmations on allopurinol therapy for urate urolithiasis. Generally, no specific clinical interpretation can be made based on the finding of amorphous crystals. Small amorphous crystals can be confused with bacterial cocci in some cases, but can be distinguished by Gram-staining. SDU-DK-1107
(Urine Sediment Analysis) Calcium oxalate dihydrate crystals • Typically are seen as colorless squares whose corners are connected by intersecting lines (resembling an envelope). They can occur in urine of any pH. The crystals vary in size from quite large to very small. In some cases, large numbers of tiny oxalates may appear as amorphous unless examined at high magnification. These crystals often are seen in normal urine from horses and cattle. They are less common in normal canine and feline urines. Urolithiasis due to calcium oxalate has been reported in both dogs and cats. In some cases, they occur secondary to abnortmal calcium (increased) excretion due to disorders of calcium metabolism (e.g. hyperparathyroidism). Miniature Schnauzers are predisposed to calcium oxalate urolithiasis, despite no abnormalities in urinary calcium excretion. Calcium oxalate dihydrate crystals can also be seen in cases of ethylene glycol intoxication. If seen in large numbers in the urine of a dog or cat with acute renal failure, consideration should be given to this diagnosis. SDU-DK-1107
(Urine Sediment Analysis) Infectious Agents in Urine Sediment SDU-DK-1107
Candida albicans (Urine Sediment Analysis) Candida SDU-DK-1107
Bacteria can be identified in unstained urine sediments when present in sufficient numbers. Rod-shaped bacteria and chains of cocci are often readily identifiable. The images at right show E.coli bacilli from a case of cystitis in a dog. However, small amorphous crystals, cellular debris, and small fat droplets can either mask or mimic cocci. If there is any doubt about the presence of bacteria, a Gram-stained smear of urine sediment (middle panel) should be examined. Urine in the bladder of normal animals is sterile. Though bacteria from the distal urethra and/or genital tract may contaminate voided specimens, they are usually too few to see if a good mid-stream collection was obtained. SDU-DK-1107
(Urine Sediment Analysis) • Although phagocytized bacteria cannot be seen in unstained wet • mounts of urine sediment, they may found in stained smears of sediment. The lower panel at the right shows a neutrophil containing phagocytized bacteria. Notice that the nucleus in this cell is round; nuclei tend to become round as neutrophils age in urine. • Bacteriuria of clinical significance, e.g., bacterial cystitis, is usually accompanied by increased numbers of white cells (pyuria). The presence of a few bacteria without pyuria is very rarely significant of infection SDU-DK-1107
Fungal (Urine Sediment Analysis) SDU-DK-1107
Microfilaria (Urine Sediment Analysis) • Microfilaria • Microfilariae of Dirofilaria immitis may be seen in the urine sediment in cases of hematuria in microfilaremic dogs. The finding is without significance, other than as an indication of heartworm disease. SDU-DK-1107
(Urine Sediment Analysis) Urinary Tract Parasites Capillaria plica is a helminth parasite of the canine urinary bladder. C. felis-cati is the feline counterpart. The ova are similar to those of Trichuris spp. in that they are oval in shape and SDU-DK-1107
(Urine Sediment Analysis) SDU-DK-1107
Urine Sediment Analysis) Cystine crystals are flat colorless plates and have a characteristic hexagonal shape with equal or unequal sides. They often aggregate in layers. Their formation is favored in acidic urine. Cystine SDU-DK-1107

Urinary Casts Urine Sediment Analysis) SDU-DK-1107
Urine Sediment Analysis) General Interpretation of casts:Casts are quantified for reporting as the number seen per low power field (10x objective) and classified as to type (e.g., waxy casts, 5-10/LPF). Casts in urine from normal individuals are few or none. An absence of casts does not rule out renal disease. Casts may be absent or very few in cases of chronic, progressive, generalized nephritis. Even in cases of acute renal disease, casts can be few or absent in a single sample since they tend be shed intermittently. Furthermore, casts are unstable in urine and are prone to dissolution with time, especially in dilute and/or alkaline urine. Although the presence of numerous casts is solid evidence of generalized (usually acute) renal disease, it is not a reliable indicator of prognosis. If the underlying cause can be removed or diminished, regeneration of renal tubular epithelium can occur (provided the basement membrane remains intact). SDU-DK-1107
Urine Sediment Analysis) Hyaline casts are formed in the absence of cells in the tubular lumen. They have a smooth SDU-DK-1107
(Urine Sediment Analysis) Granular Casts SDU-DK-1107
Urine Sediment Analysis) Fatty Casts Waxy Casts Waxy casts have a smooth consistency but are more refractile and therefore easier to see compared to hyaline casts. They commonly have squared off ends, as if brittle and easily broken. Waxy casts indicate tubular injury of a more chronic nature than granular or cellular casts and are always of pathologic significance SDU-DK-1107
