Abstract

Staging of carcinoma of the urinary bladder is important for the choice of therapy and also has prognostic implications. Hitherto the staging has been based upon cystoscopy with bio psy, transurethral resection , and palpation with complementary radiographic examlnations such as cystography, urography, lymphangiography, ultrasound and angiography. However, with all these methods, the staging of bladder carcinomas still uncertain and inferior to CT. Authors analyzed CT staging of bladder cancers and compared with pathologic staging of laparotomy results. The results are as follows: 1. Overall accuracy of CT staging in bladder carcinoma was 72 percent. 2. Overstaging was 20 percent (5/25) and understaging was 8 percent (2/25). 3. All of CT stage B cancers were proven to be stage B, pathologlcally. 4. In 6 cases of CT stagec cancers,only one was correct,3 were overstaged and 2 were understaged. 5. In 7 cases of CT stage D cancers, 5 were correct and 2 were overstaged. 6. CT detected only 2 cases of pelvic Iymph node involvement in 4 of pathologically proven Iymphadenopathy.
