title: Annular rectal constriction due to infiltration by bladder cancer.
abstract: Invasive bladder cancers frequently show lymphatic or hematogenous metastasis. Furthermore, aggressive local invasion into adjacent structures is also commonly observed. However, the occurrence of rectal stricture due to infiltration by bladder cancer is relatively rare. Here, we report three patients with aggressive bladder cancer causing rectal obstruction.
