    Intracavitary sonography offers advantages for T-classification of urinary bladder tumors compared to conventional methods. While accurate, overstaging can occur, necessitating correlation with histopathology for definitive diagnosis.

    Area of Science:

    • Urology
    • Medical Imaging
    • Oncology

    Context:

    • Urinary bladder cancer diagnosis relies on accurate staging.
    • Conventional methods have limitations in precise tumor classification.
    • Intracavitary sonography presents a potentially superior diagnostic tool.

    Purpose:

    • To evaluate the efficacy of intracavitary sonography for T-classification of urinary bladder tumors.
    • To compare sonographic findings with histopathological results in urothelial bladder cancer patients.
    • To identify factors contributing to sonographic overstaging and potential improvements.

    Summary:

    • Intracavitary sonography demonstrated advantages in T-classification of urinary bladder tumors over conventional methods.
    • In 97 patients with urothelial bladder cancer, sonography achieved 63% accuracy, with 32% overstaging.

  • Technical adjustments and examiner experience can mitigate some sonographic failures, but benign conditions mimicking cancer require histopathological correlation.

    • Impact:

    • Intracavitary sonography can improve the accuracy of bladder tumor staging.
    • Understanding sonographic limitations, such as overstaging and confusion with benign diseases, is crucial.
    • This study highlights the importance of integrating sonographic findings with histopathology for optimal patient management.
