OBJECTIVE: To investigate whether different types of injury on bladder wall can influence bacillus Calmette-Guerin (BCG) attachment.
METHODS: The bladder mucosa of 24 rabbits were treated by electrocautery,cryocautery and incision on left lateral wall, right lateral wall and posterior wall, respectively. Then radiolabeled BCG ((3)H-BCG) was instilled into bladder. Two hours latter, the injured bladder wall with different methods and non-injured wall (anterior wall of bladder) were surgically removed and digested. The quantity of BCG of each specimen was determined by liquid scintillation counter.
RESULT: The quantity of BCG attachment to bladder wall with different injuries was significantly higher than that of non-injured wall (P<0.001), meanwhile there was no statistically difference among the BCG levels of different injury types (P>0.05).
CONCLUSION: BCG attachment is not influenced by different types of injury on the bladder wall.
