A technique for continuous infusion into the mouse bladder.

E N Guillery, G W Chodak

    The Journal of Urology
    |May 1, 1984
    PubMed
    Summary

    Researchers developed a new long-term bladder catheter for mice, enabling normal voiding during intravesical infusions. This technique supports studying bladder cancer treatments over extended periods.

    Area of Science:

    • Urology
    • Oncology
    • Animal Models

    Background:

    • Investigating bladder cancer requires effective animal models for drug efficacy studies.
    • Existing methods for long-term intravesical administration in mice are limited.

    Purpose of the Study:

    • To describe a novel technique for long-term indwelling catheter placement in the mouse bladder.
    • To establish a reliable model for studying intravesical anticancer agents over several weeks.

    Main Methods:

    • A new technique for chronic catheterization of the mouse bladder was developed.
    • The technique allows for normal voiding while maintaining intravesical infusion.
    • The model supports MBT-2 tumor cell implantation into the bladder wall.

    Main Results:

    • The described catheterization technique enables prolonged intravesical infusion in mice.
    • Animals maintain normal voiding function with the indwelling catheter.
    • The model successfully facilitates tumor cell implantation for experimental purposes.

    Conclusions:

    • This novel technique provides a valuable tool for long-term bladder cancer research in mice.
    • The model is suitable for evaluating the efficacy of intravesical anticancer agents over extended treatment durations.
