[Staging of urinary bladder tumors with CT and MRI].
OBJECTIVE
The purpose of this study was to evaluate the performance of spiral CT and MRI in patients with bladder tumor.


METHODS
In this study, patients with suspected urinary bladder tumor were evaluated by abdominal CT and MRI. This study included 32 patients. In 23 cases, transurethral resection (TUR), and in 9 cases radical cystectomy was performed. Additionally, pelvic lymph node dissection was performed in 9 patients.


RESULTS
According to the pathological results of TUR-performed patients; the accuracy of spiral CT and MRI in preoperative staging of bladder tumors was 41.6% and 83.3%, respectively. The accuracy of spiral CT and MRI in preoperative staging of bladder tumors were 66.6% and 77.7% in patients who underwent radical cystectomy. Pelvic lymph node involvement was evaluated properly with MRI and CT.


CONCLUSIONS
In the preoperative staging of bladder tumors, MRI is superior to CT. The superiority is more definite especially in early stage tumors.
