** Low-grade diverticular tumors are best treated with a combination of resection and fulguration of the base.  
** '''If low-grade diverticular tumour, use combination of resection and fulguration of the base.'''
***'''Conservative resection can be followed with subsequent repeat resection''' if the final pathologic interpretation is high grade.

** '''High-grade tumors require adequate sampling of the tumor base, often including perivesical fat,''' despite the near certainty of bladder perforation.
