Genitourinary tract nuclear oncology. 
Currently available routine radionuclide procedures and on-going investigational scintigraphic studies of genitourinary tract tumors were reviewed.  Emphasis was focused on the most commonly encountered tumors located in the kidneys, bladder, and prostate.  Other imaging modalities, such as computed tomography (CT), magnetic resonance imaging (MRI), and sonography have replaced many of the routine radionuclide imaging procedures providing high-resolution images and anatomic details.  The advantages of radionuclide procedures with their simple, uninvasive, and functioning nature will continue play important role in our management of tumors of the genitourinary tract.
