Editing Non-Muscle Invasive Bladder Cancer (section)

===== Instillation =====
* '''A urinalysis is usually performed immediately before instillation to further confirm absence of infection or significant bleeding to decrease the likelihood of systemic uptake of BCG.'''
* In the event of a traumatic catheterization, the treatment should be delayed for several days to 1 week
* After instillation, some clinicians have advocated that the patient turn from side to side to bathe the entire urothelium, but there is no scientific support for this practice. Fluid, diuretic, and caffeine restriction before instillation limits dilution of the agent by urine and facilitates adequate retention of the agent for 2 hours.
* Patients are usually instructed to clean the toilet with bleach, although there is no demonstrable risk of close contact infection.
