    Electronic bladder stimulation using the PMS-3 model successfully treated paralysis in most patients, enabling complete bladder emptying and avoiding catheters. This method offers improved health outcomes by preventing infections like pyelonephritis.

    Area of Science:

    • Urology
    • Neurology
    • Biomedical Engineering

    Background:

    • Paralyzed bladders due to innervation issues often require invasive management.
    • Indwelling catheters can lead to complications such as vesicoureteral reflux and recurrent pyelonephritis.
    • Alternative methods for bladder management are crucial for improving patient health and quality of life.

    Purpose of the Study:

    • To evaluate the efficacy of electronic bladder stimulation for treating paralyzed bladders.
    • To assess the potential of the PMS-3 stimulator to achieve complete bladder emptying.
    • To determine if this technique can eliminate the need for indwelling catheters and associated complications.

    Main Methods:

    • Implantation of the PMS-3 electronic stimulator with 8 electrodes in 10 patients with paralyzed bladders.

  • Monitoring of bladder function and patient outcomes post-implantation.
  • Analysis of reasons for stimulator removal in cases where treatment was unsuccessful.

    • Main Results:

    • Successful complete bladder emptying was achieved in the majority of patients.
    • Three patients required stimulator removal due to external factors (endocarditis, pyelonephritis, limb paralysis progression).
    • Patients were able to discontinue indwelling catheter use, preventing vesicoureteral reflux and recurrent pyelonephritis.

    Conclusions:

    • Electronic bladder stimulation with the PMS-3 model is an effective treatment for paralyzed bladders, particularly in cases of peripheral paralysis.
    • This technique significantly improves patient health by eliminating catheter dependence and reducing infection risk.
    • Central paralysis may necessitate additional surgical interventions alongside stimulation therapy.
