Simple kidney cysts that are causing symptoms or blocking the flow of blood or urine through the kidney may need to be treated using a procedure called sclerotherapy. In sclerotherapy, the doctor punctures the cyst using a long needle inserted through the skin. Ultrasound is used to guide the needle to the cyst.
Note the dirt clods that are also characteristic of a mole. Gophers will not make these kinds of mounds or dirt clods. A burrow system is a vast network of interconnecting tunnels and passages. Tunnels vary in depth from 3 to 30 inches. Moles are active year round and make regular use of their tunnels.
Taking a Closer Look. Side by side, a gopher and a groundhog look quite different because the gopher's large incisors protrude from its mouth, even when closed, and the groundhog's teeth sit inside the mouth when closed. Woodchucks have white teeth, which is atypical among rodents. Gophers have yellow or brownish teeth.
