Rezum Post-Operative Care Instructions


Rezum treatment or Rezum Therapy is a minimally-invasive procedure that utilizes water vapour (steam) for the treatment of BPH (benign prostatic hyperplasia). Rezum treatment is delivered through a handheld device using cystoscopy (a small telescope passed into the urethra tube). The radiofrequency-generated water vapor in the form of steam delivers thermal energy to the enlarged prostatic tissue. Over the subsequent weeks and months your body’s natural immune system will absorb the obstructing prostate tissue allowing a more open channel for improved urinary flow. Rezum Therapy does not require any cutting. Recovery is quicker than traditional surgery, allowing for early return to normal daily activities and preservation of normal sexual function in the majority of patients.

Doctors Shekib Shahbaz and Tony de Sousa of Melbourne Urology Centre were pioneers of this new technology in Victoria. They are happy to discuss and offer Rezum treatment in Melbourne.

Rezum Post-Operative Care Instructions

What to expect:

You will have a urethral catheter that will need to remain in place for a few days until your urologist advises that it can be removed. This is because there is some prostate swelling from the procedure. You must ensure that nobody removes your catheter without direction from your urologist.

Return to activity:

  • Driving – no driving for 24 hours
  • Work – you may return to light duties after 24-48 hours
  • Lifting – avoid heavy lifting for a week following your procedure
  • Activities – walking is fine and encouraged following your procedure, however you should avoid strenuous activity for a week following your procedure.


Following catheter removal, you may experience symptoms of mild discomfort when urinating, an increased need to urinate, and/or blood in your urine or semen for around 4-6 weeks following your procedure.

Pain Management:

You may take your prescribed pain medications, or ibuprofen or paracetamol if you are experiencing discomfort.


When can I expect to see an improvement in my urinary symptoms?

Most patients will notice an improvement in their urinary flow, pressure, and bladder emptying as early as 2 weeks following the Rezum treatment. Symptoms such as urinary frequency, urgency and nocturia (urinating at night)can take up to 3 months to improve.

Head to your nearest hospital emergency department if you:

  • Have severe pain that cannot be controlled with medication
