Symptoms include pain in the abdomen, back, testicles, or side under the ribs; nausea or vomiting; general weakness; decreased output of urine; difficulty retaining urine (incontinence); or difficulty urinating.

Treatment consists of surgery to relieve\u00a0the obstruction of the kidneys and a biopsy of the removed mass.<\/p>\n
