👉 Cnephial cyst is a benign kidney cyst that typically appears in the kidneys, often due to inflammation or infection. It can be caused by a variety of factors such as infections, trauma, or certain medications. The cyst may cause symptoms like pain, swelling, or difficulty passing urine if it's located near the ureter or bladder. Treatment options depend on the size and location of the cyst, with some cases requiring surgery to remove it.
