Study Purpose

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.

Intervention

Device : Rezūm

Device : TURP

Eligibility Requirements

info icon Men 50-80 years

info icon Refractory urinary retention related to benign prostatic hyperplasia (BPH)

info icon On urethral Foley's catheter before treatment

info icon Prostate size 30-80ml on ultrasound

info icon Minimum age: 50

info icon Prior prostate operation

info icon Past or current history of prostate cancer

info icon Strong suspicion of prostate cancer (e.g. Elevated PSA before urinary retention or abnormal prostate on DRE without workup for prostate cancer)

info icon Known Urethral stricture / Bladder stone / Hypocontractile bladder

info icon Known neurological diseases which may affect bladder function (e.g. Parkinsonism, stroke)

info icon 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)
