Abstract:
1. A method of identifying a lymph node draining the bladder of a patient with bladder cancer, comprising: (a) instilling into a lumen of the patient's bladder a dye, dissolved in solution, which fluoresces at an emission wavelength when said dye is contacted with an excitation wavelength; (b) allowing the dye to be taken into the bladder and drain to said lymph node; (c) exposing the lymph node to a source of illumination comprising said excitation wavelength under conditions such that fluorescent dye in the lymph node fluoresces; and (d) detecting the presence of fluorescence of said dye in said lymph node, wherein the presence of fluorescence indicates that the lymph node is draining said bladder.
