Transurethral resection for the assessment and treatment of vesical neoplasms: a review of 840 consecutive cases.

Non-infiltrating (T1), and superficially infiltrating (T2), vesical neoplasms can be treated satisfactorily by transurethral resection. Some T3 neoplasms can be treated this way, but most will require radiotherapy. The assessment and treatment of 840 cases are presented. Survival rates of 62% in T1 cases, 59% in T2 cases, and 20% in T3 cases are reported in 465 cases followed up for 5 years.
