[Experimental model of Walker 256 carcinosarcoma in rats bladder].
OBJECTIVE
An animal model to study bladder tumor with Walker 256.


METHODS
Bladders rats Wistar was catheterized via urethra and compression lesion of the wall bladder was realized with a little clamping after laparotomy. One total of the 0,3 ml suspension with 3 x 10(5) cels viable of the carcinosarcoma was instilled into each bladder. The animals were sacrificed after eight and 13 days.


RESULTS
The index of tumor incidence was 100% and the average of surviving was 14,5 days.


CONCLUSIONS
The model studied was efficient and will can to take subsidy the study experimental in treatment of local invasive bladder cancer.
