Brief Summary

Millions of Americans are suffering from underactive bladder (UAB). The impact of severe UAB, i.e. non-obstructive urinary retention (NOUR) on quality of life is significant because current treatment for non-obstructive urinary retention requires intermittent self-catheterization or an indwelling suprapubic catheter. Currently an effective drug for non-obstructive urinary retention does not exist. It is a therapeutic challenge for clinicians to successfully treat non-obstructive urinary retention. Sacral neuromodulation has been approved by the FDA since 1999 to treat non-obstructive urinary retention. It achieves \>50% improvement in bladder emptying (reducing the frequency of self-catheterization or increasing voided volume) in just over half of the patients. Sacral neuromodulation requires surgical implantation of a stimulator and a lead with 4 electrodes. The surgery and implant are invasive and expensive, preventing a broad application of this effective therapy to many non-obstructive urinary retention patients. The goal of this study is to develop a novel non-invasive neuromodulation therapy for non-obstructive urinary retention as an alternative. Specifically, the investigators will explore the possibility to translate into humans a recent discovery in cats of an excitatory reflex from the superficial peroneal nerve to the bladder to treat non-obstructive urinary retention. Therefore, in this study the investigators propose to develop a non-invasive, transcutaneous neuromodulation therapy for non-obstructive urinary retention that can be administered at home.

Study Arms (1)

Transcutaneous Nerve Stimulator(TENS)

EXPERIMENTAL

Adult females who have difficulty emptying their bladder due to non-obstructive urinary retention or because of an under-active bladder will be given transcutaneous nerve stimulation (TENS) therapy.

Device: superficial peroneal nerve stimulation

Interventions

A commercially available FDA-approved transcutaneous electrical nerve stimulator (TENS) and skin surface electrodes will be used to stimulate the foot. The electrodes will be attached to the dorsal surface of the foot and a sock will be placed over the foot to prevent detachment of the electrodes. Based on our animal studies, foot stimulation parameters of 2 Hz frequency and 0.2 ms pulse width will be used at the maximal intensity comfortable for each patient. It is expected that superficial peroneal nerve stimulation in patients can increase bladder sensation so that micturition can be initiated at a small bladder volume, or it can initiate bladder contraction at a small bladder volume and enhance the contraction or prolong the duration of contraction. Any of these excitatory effects, if occurs in human patients, will certainly improve the condition of non-obstructive urinary retention.

Model Details: All experiments proposed in this grant application will be performed in female non-obstructive urinary retention patients. We chose not to study male patients in this study given the need to exclude bladder outlet obstruction from benign prostatic hyperplasia (BPH), an evaluation that is invasive and costly.
