    Researchers found that the signal spectra of ureteral smooth muscle activity fall within the 0.05--1 Hz range. New devices can now assess the functional state of the urinary system by measuring ureteral electrograms and dynamograms.

    Area of Science:

    • Physiology
    • Biomedical Engineering

    Context:

    • Investigating the functional state of the urinary system is crucial for diagnosing various conditions.
    • Ureteral smooth muscle activity generates bioelectrical and mechanical signals that reflect urinary system function.

    Purpose:

    • To determine the characteristic signal spectra of ureteral smooth muscle activity.
    • To develop devices for registering ureteral electrograms and dynamograms.

    Summary:

    • Signal spectra analysis revealed that bioelectrical and mechanical activity of ureteral smooth muscles occur within the 0.05--1 Hz frequency range.
    • Novel devices were created to record these electrograms and dynamograms.

    Impact:

    • The developed devices offer a new method for evaluating the functional state of the urinary system.
