Photodynamic Diagnosis

FIG. 25:  There are 3 areas where PDD can improve cancer management in T1 patients (Figure).  Smaller adjacent tiny lesions that are often overlooked can be visualized.  Flat lesions, which are often not seen next to the T1 bladder cancer or elsewhere in the bladder, can also often be visualized thanks to metabolic uptake in PDD.  This also allows identification of the address of the tumor, to ensure adequate resection and to diminish the local recurrence rate.
