Abstract

BACKGROUND:
Transitional cell carcinoma of the bladder is one of the most widely recognized cancers affecting the genitourinary tract and it is the second most common cancer in Iraqi male population .Cross sectional imaging studies assume a significant role in the staging of this cancer , also the prognosis of the patients with bladder carcinoma worsens with higher stage and accurate preoperative radiological staging is required to increase cancer free survival for patients submitted for radical cystectomy.
OBJECTIVE:
To compare the accuracy of computed tomography and magnetic resonance imaging for staging of muscle-invasive bladder cancer.
PATIENTS AND METHODS:
Twenty patients were included in the study hnd undergone staging for their muscle invasive bladder cancer by the use of computed tomography scan and magnetic resonance imaging at least two weeks of their last trans-urethral resection of tumour, the radiological staging was compared to the staging of the histopathological reports of the radical cystectomy of the included patients.
RESULTS:
The staging accuracy of the computed tomography was 93.8%, sensitivity 88.8%, specificity 90.2%, while magnetic resonance imaging accuracy of staging was 71.30%, sensitivity 45.8%, specificity 81.70%. Accuracy increased with advancing stage.
CONCLUSION:
It is concluded that computed tomography staging is more accurate than magnetic resonance imaging tumor staging in patients with muscle invasive bladder cancer, with comparable results in lymph node staging.
