About this study

The purpose of this study is to gain a better understanding of what causes urinary urgency in women by asking about different symptoms and measuring biomarker levels in their urine. Understanding the underlying causes of urinary urgency will allow us to develop treatment options to better take care of women with urinary urgency.

Read the detailed description

We propose to test the hypothesis that urinary urgency in women is caused by neurogenic inflammation that is manifested clinically as neuropathic pain and associated with the expression of neuroinflammatory biomarkers in the urine.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine the association between the severity of neuropathic pain and the severity of urinary symptoms in women with urinary urgency.

    We propose a prospective cross-sectional study. We will recruit 137 women with urinary urgency and without incontinence or infection. All women will complete validated symptom questionnaires to measure neuropathic pain, urinary, bowel, sexual symptoms and quality of life. All patients will bring a first morning clean catch urine void to the office on ice within one week of completing the questionnaires. The specimen will be transported to the lab within 24 hours and stored at -80 degrees. Enzyme-linked immunosorbent assays (ELISA) will be used to determine expression of urinary creatinine and neuropeptides. The primary outcome will be the severity of urinary symptoms as measured by the Interstitial Cystitis Symptom Index.

    Measured: 1 year

Secondary outcomes (1)
  1. The association between neuropathic pain and the expression of potential neural biomarkers in the urine of women with urinary urgency.

    To determine the association between the severity of neuropathic pain and expression of urinary neurotrophic peptides in women with urgency. We hypothesize that in women with urinary urgency, increasing severity of neuropathic pain will be associated with increasing levels of urinary neurotrophic peptides NGF and BDNF. Nerve growth factor (NGF) and Brain-Derived Neurotrophic factor (BDNF) - NGF and BDNF are neurotrophic growth factors that are released in urine from different cell types in the bladder wall making urine a convenient sample for measurement of their levels. Activation of the myelinated A fiber and unmyelinated C fibers in the bladder wall can lead to an elevation in NGF and BDNF levels, sensitization of bladder afferent pathways and development of neurogenic inflammation in the urinary bladder [2,3].

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Overactive Bladder, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine the association between the severity of neuropathic pain and the severity of urinary symptoms in women with urinary urgency. (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2014.
