[Computed tomographic staging of bladder tumors].

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Cystoscopy is primary for bladder tumor diagnosis but struggles with deep wall infiltration and perivesical spread.
• Accurate staging is crucial for effective bladder cancer treatment planning.

Purpose of the Study:

• To evaluate the diagnostic accuracy of Computer Tomography (CT) in staging bladder tumors.
• To assess CT's capability in determining tumor depth and perivesical dissemination.

Main Methods:

• Retrospective analysis of 43 patients with diagnosed bladder tumors.
• Comparison of CT findings with surgical intervention results for staging accuracy.
• Description of CT's morphologic patterns for perivesical tumor spread.

Main Results:

• CT demonstrated 88% accuracy in determining the T-stage (tumor depth).
• CT showed 67% accuracy in determining the H-stage (histological grade/invasion).
• T3-A was the earliest tumor stage detectable by CT; CT identified perivesical dissemination patterns.

Conclusions:

• CT is a valuable tool for assessing bladder tumor depth and perivesical spread.
• CT can accurately stage bladder tumors, complementing cystoscopy.
• A proposed scheme integrates CT into the overall assessment of bladder cancer patients.
