Assessment & Preparation
Assessment & Preparation
Your doctor will review the following with you to help in assessing the risks for the Rezūm procedure for benign prostatic hyperplasia and help avoid unnecessary complications:
The physician will evaluate your medical history to gain a comprehensive knowledge of your overall health status, including information related to the medications that are currently being taken.
Some medications increase a person’s chances of bleeding and it may be recommended to discontinue them for a period of time before the procedure is performed.
The procedure is generally well tolerated and has minimal contraindications, however you doctor will review the possible complications and contraindications with you to ensure that a good decision is made and that you have your questions answered.
At the pre-procedure visit, the patient receives detailed instructions on pre- and postoperative care. He will also receive an antibiotic prescription that should be started the night before the procedure. Anti-inflammatories are given the day before and after the procedure. An alpha blocker prescription may be given to improve the flow of urine after the procedure.
Once you have made the decision to have the Rezūm water vapour therapy you will have some pre-procedure instructions to follow, which may include:
On the day of the procedure, a light meal and lots of fluids are recommended.
The procedure itself is quick and simple, taking only a single office visit. Depending on the size of the prostate, the procedure consists of two to seven injections, each nine seconds long.
Upon arriving, the patient will be instructed to eliminate urine, and the bladder is then checked. If there is still more urine in the bladder, it’s drained to avoid having to drain it during the procedure.
Both the prostate and the penis are numbed. The Rezūm device is inserted, a needle is deployed, and vapor is injected into the prostate for nine seconds. This vapor disperses between cells, then cools, releases heat, and gently disrupts the prostate’s cells.
Because of the initial swelling, a catheter is then inserted, which will remain for two to five days. The catheter is hooked to a bag that stays on the leg and is covered by pants. A driver is required to take the patient home.
After the Rezūm procedure, the body creates an inflammatory response, which takes two to four months to completely resolve. Initially, there will be swelling in the prostate, which can cause restriction of flow and cause more difficulty and frequency of urination.
Symptoms will get worse before they get better. Generally, at two weeks symptoms begin to stabilize. At four weeks, patients are back where they were before the procedure, and at six weeks patients start to get off medication.
Erections are not affected by the Rezūm procedure. There is a one to two percent chance of retrograde ejaculation, which occurs when semen enters the bladder instead of the penis, causing very little to no semen to be ejaculated. This is a significantly lower percentage than in other prostate procedures.
Rezūm is a minimally-invasive procedure and has fewer side effects compared to surgical therapies. The main precaution after the procedure is limiting strenuous activity until the catheter is removed. However, as with any intervention, some of the following side effects may occur for a short period of time:
Follow instructions and take any medications prescribed by the urologist, including:
In a majority of cases, individuals are able to fully recover from the procedure within a few days to a week. They often note an improvement in BPH symptoms within a few weeks and after 3 months, most individuals are able to feel a complete relief from the symptoms.
