Official title
A Randomized Controlled Trial Comparing Water Vapour Thermal Therapy (Rezūm) and TURP in Men With Benign Prostatic Hyperplasia in Refractory Urinary Retention
Overview
This is a randomized controlled trial using a non-inferiority design with the subjects randomized 1:1 to either water vapour thermal treatment (REZUM) arm or transurethral resection of prostate (TURP) arm.
Interventions
- Device Rezūm
In the REZUM arm, water vapour treatment is performed for all subjects under local anaesthesia. - Device TURP
In the TURP arm, all men will receive TURP operation under general or spinal anaesthesia
Primary outcome measures
- Changes in International Prostate Symptom Score (IPSS) at 12 months after treatment [Time frame: Baseline, 3 months, 6 months and 12 months after intervention]
Secondary outcome measures (7)
- Successful trial without catheter (TWOC) within 3 months [Time frame: At 3 months]
- Complication rate [Time frame: 30 days after intervention]
- Post-op quality of life score [Time frame: Baseline, 3 months, 6 months and 12 months after intervention]
- Change in voiding function in uroflowmetry [Time frame: Baseline, 3 months, 6 months and 12 months after intervention]
- Post-op International Index of Erectile function score [Time frame: Baseline, 3 months, 6 months and 12 months after intervention]
- Hospital stays of procedure [Time frame: On Discharge]
- Unplanned readmission rate after operation in 30 days [Time frame: 30 days after intervention]
Eligibility criteria
Inclusion criteria
- Men 50-80 years
- Refractory urinary retention related to benign prostatic hyperplasia (BPH)
- On urethral Foley's catheter before treatment
- Prostate size 30-80ml on ultrasound
Exclusion criteria
- Prior prostate operation
- Past or current history of prostate cancer
- Strong suspicion of prostate cancer (e.g. Elevated PSA before urinary retention or abnormal prostate on DRE without workup for prostate cancer)
- Known Urethral stricture / Bladder stone / Hypocontractile bladder
- Known neurological diseases which may affect bladder function (e.g. Parkinsonism, stroke)
- Contraindicated to undergo TURP or REZUM (e.g. not fit for GA/SA, active urinary tract infection, fail to be placed in lithotomy position, uncorrectable coagulopathy, antiplatelet or anticoagulant which cannot be stopped)
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
