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.
Ground squirrels dig holes, of course, and they are easy to spot, as are gopher holes and mole holes, with the dirt piled around the entrances. Moles tend to have their entrances in the center of the excavated dirt, so it looks like a volcano, while gopher holes are eccentric.
