Cara Baca Hasil Pemeriksaan Urine (Studi Kasus)

Summary

The video demonstrates how to interpret a urinalysis using three complementary components: macroscopic examination, chemical dipstick testing, and urine sediment microscopy. The presenter emphasizes that findings should be interpreted together, since results from different parts of the urinalysis may agree or differ.

Case interpretation

The example concerns a patient named Ahmad. His urine is described as dark yellow and cloudy. The presenter interprets the color as consistent with concentrated urine, supported by a specific gravity of 1.030. The urine is also acidic. Cloudiness may be associated with infection, but the other findings are needed to assess that possibility.

Dipstick findings

• Glucose: +1. The presenter raises the possibility of diabetes mellitus but says this should be confirmed with blood glucose testing. Vitamin C may interfere with the glucose reaction and make the result appear lower than it is.
• Protein: +3. This is treated as a significant finding that may indicate kidney involvement, though it does not by itself prove kidney damage.
• Nitrite: +1 and leukocyte esterase: +3. Together with cloudy urine and bacteria in the sediment, these findings support the presenter’s interpretation of a urinary tract infection (UTI). Nitrite positivity may reflect bacteria that convert nitrate to nitrite.
• Blood: +2. The presenter compares this result with the sediment findings to distinguish blood cells in the urine (hematuria) from hemoglobin alone.
• Bilirubin: negative; urobilinogen: normal; ketones: negative. The presenter uses these results to argue that bilirubin does not explain the dark urine and that the findings do not point to ketone-related ketoacidosis.

Sediment findings

• Red blood cells: About 20–30 per high-power field (as transcribed), consistent with microscopic hematuria.
• White blood cells: About 30–32 per field, indicating substantial pyuria.
• Bacteria: +2, supporting the suspected UTI.
• Epithelial cells: Squamous cells are reported as relatively numerous, with transitional and renal tubular epithelial cells also noted. The presenter considers the renal tubular cells a possible sign of kidney involvement.
• Casts: Hyaline casts are reported at about 2–4 per low-power field, granular casts at about 8–9, and leukocyte casts at about 2–3. The transcript also appears to mention very few red-cell casts. The presenter relates casts to material formed in the kidney tubules.
• Calcium oxalate crystals: +2. These may be relevant to stone risk but do not establish that stones are present. The presenter also discusses vitamin C as a possible source of oxalate and as a potential source of dipstick interference.
• Mucus: positive. Calcium phosphate and triple phosphate crystals are reported as absent, which the presenter relates to the acidic urine.

Overall interpretation and follow-up

The presenter’s working interpretation is a likely UTI with pyuria and hematuria, possibly involving nitrate-reducing bacteria, alongside possible diabetes and kidney involvement. These are interpretations of the urinalysis, not confirmed diagnoses.

The video recommends correlating the urine findings with other tests, including:

• Blood glucose testing to assess the possibility of diabetes.
• Blood chemistry tests, including urea and creatinine, to evaluate kidney function.
• Hematology testing, which the presenter says could help assess anemia or an elevated white-cell count.

The presenter also stresses that vitamin C may affect the apparent urine glucose result. The transcript is unclear in places, so exact sediment counts and some technical terms should be treated cautiously.
