A rabbit is presented for hematuria, stranguria, lethargy, and anorexia. A UA is performed and a radiograph is taken and uroliths are diagnosed. The rabbit is anesthetized and a cystotomy is performed to correct the problem. (Key: remember, the color of rabbit urine can vary from clear to white to red depending on diet and individual variation.) Another term for urolith is:

A) nephrolith
B) renolith
C) bladdolith
D) cast
E) urinary calculus
