along with disruption of the tubular linings.

Answer 17

cast with jagged ends and notches

Answer 27

waxy cast

Question 28

indicates destruction
(widening) of the tubular walls. Also, when the flow of urine

wider than normal cast

Answer 29

broad cast

caused by crystallization of medications compounds
within the tubules

Answer 30

urinary crystal
