2

______ cells originate from the renal pelvis to the upper urethra.

Transitional cells originate from the renal pelvis to the upper urethra.

3

________ cells originate from lower urethra or are vaginal contamination.

Squamous cells originate from lower urethra or are vaginal contamination.

4

Most common yeast found in urine?

Candida albicans

5

Factors that affect urine formation?

pH, solute concentration, kidney filtration rate

6

Important characteristics for classifying urine crytsals

pH, Morphology, Polarization and bifringence, and solubility

7

Crystals commonly found in acidic urine

uric acid, urates, calcium oxalates

8

Where are casts formed?

Formed in lumen of the kidney distal convoluted tubules and Loop of Henle.

9

This comprises the matrix of a cast

Tamm-Horsfall mucoprotein

10

Cast formation factors

urinary stasis, acid pH, high solute concentration, abnormal ionic or protein constituants

11

T/F Casts may be indicated by the presence of protein?

True, must follow up with microscopic examination

12

This cast is frequently present in those following physical exercise and physiologic dehydration.

Hyaline Cast

13

These casts can be present after exposure to nephrotic agents and viruses due to the damage that accompanies glomerular injury and may also be present in the rejection of a kidney allograft.
