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.
The aboveground damage they cause, however, is quite apparent. Entire plants can disappear before your eyes, pulled down by the roots as a gopher snack. Once a gopher infestation begins, the yard becomes riddled with mounds roughly 1 foot in diameter. These are the deposits of soil cleared to expand their tunnel system. They are usually horseshoe shaped with a distinct plug of soil in the middle that caps the hole.
