title: Staging of bladder tumors by transrectal ultrasonotomography and U.I. Octoson.
abstract: The staging of bladder tumors was performed in 100 cases by transrectal ultrasonotomography and in 44 cases by U.I. Octoson. Complete agreement between histology and ultrasound was obtained in 80% of the cases by the former method and in 73% by the latter method for tumors arising from the corpus of the bladder. However, agreement was obtained in only 38% of the cases by the former method and in 59% by the latter method for tumors arising from the apex and fundus of the bladder. The possibility of improving the agreement for tumors in the apex and fundus by introducing real-time transrectal linear scanning is suggested.
