Rezum therapy is a new minimally invasive transurethral method of treatment for enlarged prostate, also known as benign prostatic hyperplasia (BPH).
Rezum therapy works by using thermal energy produced by water vapour to treat the hyperplastic prostate tissue, which is responsible for BPH symptoms.
Rezum therapy for BPH has a lot of benefits and minimal transient side effects during the surgical procedure. Rezum therapy as a procedure in some cases is preferable over other BPH treatments as it offers the following benefits:
In order to prepare for the surgery, the patient should be adequately counselled to ensure that the informed consent obtained is fully understood.
The doctor then runs a number of tests to ensure that the patient is fit and in good health for the surgery. These will include
Before surgery, Flexible Cystoscopy may also be performed to assess prostate enlargement and exclude other pathology (ie. bladder tumour).
In preparation for the surgery, an IV line is inserted in his arm. The anaesthesia administered will either be general or spinal in nature, which is decided by the anaesthetist and surgeon on a case by case basis.
The surgical device required for this operation is a transurethral delivery and a radiofrequency (RF) generator. This transurethral wand also incorporates a standard cystoscopy lens and a retractable vapour needle that delivers the water vapour.

The surgery includes the following steps:
The patient is kept in the recovery room for observation and their vitals are monitored.
Pain medication is administered as needed via IV lines if required. In a few hours, the patient is discharged home if well.
The catheter is required and is generally kept in place for 3-7 days after surgery. This ensures that urine can pass without problems. The longer catheter duration and a higher risk of infection compared to other surgical procedures are one of the main downsides of REZUM. As the recovery progresses, the catheter is removed.
Patients can return to their regular daily life activities within a few days of the procedure. Pain medication can also be taken on an as per need basis.
A care plan will be devised for the patient for the next few months, to aid in recovery and to help improve bladder control. Dr Hadley and his team will also advise a follow-up visit chart to check the patient progress in the clinic as well and to check for any post-surgical complications.
