What is being measured

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

  1. Changes in International Prostate Symptom Score (IPSS) at 12 months after treatment

    IPSS score ranging from 0-35 (the higher the worse)

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

Secondary outcomes (11)
  1. Hospital stays of procedure

    Measure the hours of in-patient hospitalisation

    Measured: From the time patient is hospitalised until the time he discharges

  2. Number of days on Foley's catheter or self-catheterization after operation

    Measured: 30 days after intervention

  3. Complication rate

    Assessed by Clavien-Dindo classification

    Measured: 30 days after intervention

  4. Post-op quality of life score (International Prostate QOL score)

    Change in quality of life assessed by change in International Prostate QOL score (Ranges from 0 to 6; 0 being the best while 6 being the worst)

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  5. Post-op quality of life score (EQ5D-5L questionnaire)

    Change in quality of life assessed by Quality of life: EQ5D-5L questionnaire

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  6. Change in voiding function in uroflowmetry (Maximum flow rate)

    It is assessed by maximum flow rate (ml/s) in uroflowmetry

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  7. Change in voiding function in uroflowmetry (Post void volume)

    It is assessed by post void volume (ml) in uroflowmetry

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  8. Post-op erectile function (IIEF-EF)

    Assessed by Erectile function and Ejaculatory function using International Index of Erectile Function Questionnaire - Erectile function domain (IIEF-EF)

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  9. Post-op erectile function (MSHQ-EjD-SF)

    Assessed by Erectile function and Ejaculatory function using Male Sexual Health Questionnaire - ejaculatory dysfunction (EjD) Short Form (MSHQ-EjD-SF)

    Measured: Baseline, 3 months, 6 months and 12 months after intervention

  10. Unplanned readmission rate after operation in 30 days

    Percentage of patients with unplanned readmission

    Measured: 30 days after intervention

  11. Cost of procedure and related hospitalization

    Measured: At 12 months after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Rezum and UroLift in people with Benign Prostatic Hyperplasia, run by Chinese University of Hong Kong at 1 site in Hong Kong.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. 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: looking for participants now, as of the sponsor's last update on 27 Oct 2026. 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 Hong Kong. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Peter Ka-Fung CHIU (+852 3505 2625, peterchiu@surgery.cuhk.edu.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in International Prostate Symptom Score (IPSS) at 12 months after treatment (time frame: Baseline, 3 months, 6 months and 12 months after intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06820606, which also lists 13 linked publications.

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 27 Oct 2026.
