Everything you need to know about Rezūm therapy, the patient journey, costs, insurance, and what to expect.
Rezūm is indicated for men with moderate to severe BPH (I-PSS ≥ 8), prostate volume between 30 and 80 cc, including cases with median lobe hyperplasia. It is ideal for patients who wish to preserve sexual function and avoid major surgery. A full assessment with Prof. Rabii is required to confirm eligibility.
No. Rezūm is specifically designed to preserve sexual function. The water vapor remains contained within the prostate stroma, leaving the neurovascular bundles that control erection and the ejaculatory ducts intact. Clinical studies show preservation of erectile and ejaculatory function in the vast majority of patients — a major advantage over TURP.
Rezūm is performed under local or locoregional anesthesia in an outpatient setting. Patients typically feel mild pressure or warmth during the steam injections. Post-procedurally, minor burning, urgency or hematuria are normal and transient, resolving in 1–2 weeks.
Most patients notice measurable improvement within 2 weeks of catheter removal. Optimal results are reached at 3 months, once the body has fully reabsorbed the destroyed tissue. Published studies show an average I-PSS score reduction of ~50% at 3 months.
During the inflammatory phase (approximately weeks 2–4), the immune system is actively reabsorbing the necrotic tissue. This process can cause transient swelling that temporarily worsens urinary flow. This is a normal part of healing and does not indicate treatment failure.
Yes. A temporary urinary catheter is required for approximately 3–10 days to allow the prostate to rest and initial healing to occur. The catheter is removed during a clinic visit once spontaneous, satisfactory voiding is confirmed.
Rezūm has an excellent safety profile. Common transient effects include mild hematuria, dysuria and urinary urgency. Serious complications (infection, urinary retention beyond 10 days) are rare (<2%). There is no anesthesia risk since only local anesthesia is used. There is no risk of retrograde ejaculation or erectile dysfunction.
Partial reimbursement is possible under CNSS and CNOPS for both the pre-operative work-up and medical consultations. The Rezūm procedure itself may be coded under specific act codes — verify with the clinic's administrative team who will assist with prior authorization.

Absolutely. For domestic or international patients, the first consultation can be conducted by secure video link. Send your medical records (PSA, prostate ultrasound, I-PSS score) in advance and Prof. Rabii's team will schedule a video consultation within 48 hours.
TURP (bipolar electric resection) and HoLEP (holmium laser enucleation) are highly effective surgical options but require general or spinal anesthesia, hospitalization, and carry significant risk of retrograde ejaculation. Rezūm offers comparable symptom relief with a dramatically superior sexual function preservation profile, shorter procedure time, and outpatient discharge. For very large prostates (>80–120 cc), HoLEP may be more appropriate — discuss with Prof. Rabii.
