Abstract

Random biopsy of normal-looking mucosa of the bladder at the time of T.U.R.B. in the patients with bladder cancer have been used as a routine assessment of the tumor behavior. To investigate mucosal abnormalities of normal-looking mucosa in bladder cancer. we performed random mucosal biopsies during transurethral resection of the bladder cancer. The following results were obtained. 1. In Group 1 (Solitary, Stalk, Papillary ca). no CIS lesion was found in biopsy specimens. 2. In Group 2 (Solitary. Sessile. Papillary ca) and Group 3 (Solitary. Sessile. Non-papillary ca). some positive results were obtained. On the consideration of above results and the potentiality of implantation. we can raise an issue that the bladder cancer patients with a solitary, papillary shape do not necessarily undergo the mucosal biopsy during T.U.R.B. Instead, close follow up for the patients will be recommended.
