Study summary

Current gold standard of bladder outlet diagnosis is pressure flow study. This study is invasive time consuming and requires expensive and complex set-up. In this study the investigators plan to evaluate an alternative technology that presumably is able to diagnose bladder outlet obstruction using a Dynamic Urine Vibration "Holter" based on a Urine Flow Vibration Analysis technology. The acoustic vibration sensor is a small device that records the vibration due to urine flow. The patient attaches the sensor to the penis using a disposable sensor patch for the duration of approximately one minute during one urination. The analysis is performed off-line and the results are compared to the results of a standard pressure flow study and to the standard free flowmetry test. The innovative technology for the diagnosis of bladder outlet obstruction is noninvasive, rapid and does not involve complex setup.

Inclusion criteria

  • clinical diagnosis of benign prostatic hyperplasia (BPH)
  • has indication for urodynamic evaluation
  • Males 18 years and older
  • Capability of understanding and having signed the form after full discussion of the research, nature of the treatment, and its risks and benefits.

Exclusion criteria

Exclusion Criteria:

Any condition which, in the investigator opinion, makes the patient unsuitable

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 31, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
