allow prolonged periods of therapy
[81]. Surgical excision of
BE nodules should be performed if pain persists despite
medical treatment, when the lesion causes ureteral
stricture, and for patients with a contraindication to
hormonal therapies or who refuse these drugs. The primary
goal of surgery should be complete removal of the bladder
nodule; consequently, when surgical treatment is chosen,
TUR alone should be avoided.
