<unk>  is a medical term for surgical removal of all or part of the urinary bladder. It may also be rarely used to refer to the removal of a cyst. The most common condition warranting removal of the urinary bladder is bladder cancer. Two main types of<unk> es can be performed. A partial<unk>  (also known as a segmental<unk>  involves removal of only a portion of the bladder. A radical<unk>  involves removal of the entire bladder along with surrounding lymph nodes and other nearby organs that contain cancer. Evaluation of the tissue removed during<unk>  and lymph node dissection aids in determining pathological cancer staging. This type of cancer staging can be used to determine further work-up, treatment, and follow-up needed along with potential prognosis. After the bladder has been removed, a urinary diversion is necessary to allow elimination of urine.
