Body Fluids Exam 2 Flashcards
This renal disease is caused by Group A Strep
Acute Glomerulonephritis
In what renal disease are RBC casts a “defining” finding?
Acute Glomerulonephritis
What is shown in these photos? What disease correlates with finding these in the sediment?
- RBC casts
- Acute Glomerulonephritis
How do RBCs differ from yeast in appearance?
Yeast typically has buds
Fatty urine is a sign of what renal disease?
Nephrotic syndrome
This renal disease is a complication of other renal diseases or systemic shock
Nephrotic syndrome
In Nephrotic Syndrome, a loss in _____ ______ triggers fat production and fats then leak through and end up in the urine.
Serum protein
A diabetic patient is admitted with oliguria and swelling of the hands and ankles.
Their urine is yellow, turbid, and foamy.
Dipstick results are as follows: Protein is 4+, Blood is Moderate, Trace Glucose, Moderate LE.
Microscopic reveals 20-30 RBC/hpf, 25-30 WBC/hpf, Many RTEs, 0-2 fatty casts/lpf, and few oval fat bodies.
What is probable diagnosis?
Nephrotic syndrome
What crystals might you see in a patient with nephrotic syndrome?
Cholesteral crystals
This renal disease is typicall due to severe infection but can also result because of shock or toxins.
Acute tubular necrosis
In what renal disease might you see RTE casts?
Acute tubular necrosis
This urinary tract infection my have WBC casts seen in the microscopic. Dipstick results would include LE+ and Nitrite +/-.
Pyelonephritis
This UTI is considered a lower UTI. You will NOT see WBC casts. LE+, Nitrite +/-, bacteria, protein and some blood are all possibilities.
Cystitis
This renal disease can be either acute or chronic. Possible casts seen in microscopic include: RTE, granular, waxy, and broad. Symptoms include: acid-base imbalances, increased urea (possible cause of psychosis), and decreased erythropoietin (causing anemia).
Renal failure
If the kidneys are unable to excrete acids, this can occur.
Renal tubular acidosis
In renal tubular acidosis, _______ pH is low while _______ pH is high.
Blood pH is low while urine pH is high
What is performed on infants 3-5 days after birth?
Newborn Screening Tests
What are the newborn screening tests looking for?
- Errors in metabolism
- Endocrinopathies
- Cystic fibrosis
- Hemoglobinopathies
What microorganism is sometimes the cause of glomerulonephritis in children?
Group A strep
When red cells are allowed to sit in a hypotonic environment, what can happen to them?
Ghost cells
If red cells are allowed to sit in a hypertonic environment, what can happen to them?
Crenation
Normal range for RBCs in a urine microscopic
< 2/hpf
Normal range of WBCs in a urine microscopic
0-5/hpf
What is the typical WBC seen in urine?
Segmented neutrophils
When are lymphocytes seen in urine?
Inflammation due to kidney rejection
Term for presence of WBCs in urine
Pyuria
Term for inflammation of the bladder
Cystitis
Term for inflammation of the urethra
Urethritis
Term for kidney infection
Pyelonephritis
When WBCs are allowed to sit in a hypotonic environment, what can happen?
Glitter cells
What would you expect the pH to be (acidic or alkaline) if both bacteria and WBCs are present in the urine?
Alkaline
These are considered a vaginal contaminant and typically indicative of bacterial vaginosis due to Gardnerella vaginalis
Clue cells
These epithelial cells are associated with the lower urinary tract
Squamous epithelial
What epithelial cells are associated with bladder and ureters?
Transitional epithelials
These epithelials are typically seen with bladder infections and catheterized urine.
Transitional epithelials
These epithelials are associated with the kidneys. Seeing >2/hpf is considered significant
Renal tubular epithelials
What phenomenon occurs when WBCs are allowed to sit in a hypotonic urine?
Glitter cells
These epithelials typically have a central nucleus and may be pear shaped or caudated
Transitional epithelials
What renal disease are oval fat bodies typically associated with?
Nephrotic syndrome
