Renal epithelial cells originate in the ______ ______?
Renal epithelial cells originate in the convoluted tubules
______ cells originate from the renal pelvis to the upper urethra.
Transitional cells originate from the renal pelvis to the upper urethra.
________ cells originate from lower urethra or are vaginal contamination.
Squamous cells originate from lower urethra or are vaginal contamination.
Most common yeast found in urine?
Factors that affect urine formation?
pH, solute concentration, kidney filtration rate
Important characteristics for classifying urine crytsals
pH, Morphology, Polarization and bifringence, and solubility
Crystals commonly found in acidic urine
uric acid, urates, calcium oxalates
Where are casts formed?
Formed in lumen of the kidney distal convoluted tubules and Loop of Henle.
This comprises the matrix of a cast
Cast formation factors
urinary stasis, acid pH, high solute concentration, abnormal ionic or protein constituants
T/F Casts may be indicated by the presence of protein?
True, must follow up with microscopic examination
This cast is frequently present in those following physical exercise and physiologic dehydration.
