What is TUMT? Purpose, Procedure & Results

TUMT stands for Transurethral Microwave Thermotherapy, a minimally invasive treatment that uses controlled heat to shrink enlarged prostate tissue. This outpatient procedure offers relief from bothersome urinary symptoms without the need for major surgery, making it an appealing option for many men dealing with benign prostatic hyperplasia (BPH).

What is TUMT?

TUMT is a heat-based treatment that targets excess prostate tissue causing urinary problems. The procedure uses a special catheter equipped with a microwave antenna to deliver precise, controlled heat directly to the enlarged prostate tissue.

Think of it as a targeted heating system that works from the inside out. The microwave energy heats the prostate tissue to temperatures between 113-140°F, which causes the excess tissue to gradually shrink over time. This shrinkage opens up the urinary pathway, allowing urine to flow more freely.

The treatment is considered minimally invasive because it doesn't require any surgical incisions. Instead, the catheter is inserted through the natural urinary opening, making recovery much gentler than traditional prostate surgery.

Why is TUMT done?

TUMT is primarily performed to treat moderate to severe urinary symptoms caused by an enlarged prostate, a condition called benign prostatic hyperplasia (BPH). As men age, their prostate naturally grows larger, sometimes pressing against the urethra and making urination difficult.

Your doctor might recommend TUMT if you're experiencing troublesome symptoms that haven't responded well to medications. These symptoms can significantly impact your quality of life and sleep patterns.

Common symptoms that lead to TUMT include:

• Frequent urination, especially at night
• Weak or interrupted urine stream
• Difficulty starting urination
• Feeling like your bladder isn't completely empty
• Urgency to urinate that's hard to control
• Straining during urination

The procedure is often considered when medications haven't provided adequate relief but you want to avoid more invasive surgical options. It's particularly suitable for men who want to maintain their sexual function, as TUMT typically has fewer sexual side effects than other treatments.

What is the procedure for TUMT?

TUMT is performed as an outpatient procedure, meaning you can go home the same day. The treatment typically takes 45 minutes to an hour, and you'll be awake but comfortable throughout the process.

Before the procedure begins, your doctor will give you local anesthesia to numb the area and may also provide light sedation to help you relax. A cooling system protects the urethral lining while the microwave energy targets the deeper prostate tissue.

Here's what happens during the procedure:

1. A thin, flexible catheter with a microwave antenna is inserted through your urethra
2. The catheter is positioned precisely within the enlarged prostate tissue
3. Controlled microwave energy is delivered to heat the target tissue
4. A cooling system protects surrounding healthy tissue
5. The heating process continues for about 30-45 minutes
6. The catheter is removed once treatment is complete

During the treatment, you might feel some warmth or mild discomfort, but the cooling system helps minimize any unpleasant sensations. Most patients tolerate the procedure well and can read or listen to music during treatment.

How to prepare for your TUMT?

Preparing for TUMT involves several straightforward steps that help ensure the procedure goes smoothly and safely. Your doctor will provide specific instructions tailored to your situation, but most preparations are simple and manageable.

In the days before your procedure, you'll need to stop taking certain medications that could increase bleeding risk. Your doctor will give you a complete list, but common medications to avoid include blood thinners and some pain relievers.

Here are typical preparation steps:

• Stop taking blood-thinning medications as directed by your doctor
• Arrange for someone to drive you home after the procedure
• Take prescribed antibiotics if your doctor recommends them
• Avoid eating or drinking for a few hours before treatment if sedation is planned
• Wear comfortable, loose-fitting clothing
• Bring a list of all your current medications

Your doctor may also recommend starting antibiotics a day or two before the procedure to prevent infection. This is a precautionary measure that helps ensure your recovery goes smoothly.

How to read your TUMT results?

TUMT results aren't immediate like a blood test – instead, you'll experience gradual improvement over several weeks to months. The heated prostate tissue takes time to shrink and be naturally absorbed by your body, so patience is key during the healing process.

Most men begin noticing improvements in their urinary symptoms within 2-4 weeks after treatment. However, the full benefits of TUMT may not be apparent for 2-3 months as the prostate continues to shrink gradually.

Signs that TUMT is working include:

• Stronger, more consistent urine stream
• Reduced frequency of urination, especially at night
• Easier initiation of urination
• More complete bladder emptying
• Decreased urgency to urinate
• Less straining during urination

Your doctor will monitor your progress through follow-up appointments and may use questionnaires to track symptom improvement. Some men experience 50-70% improvement in their urinary symptoms, though individual results vary based on factors like prostate size and overall health.

How effective is TUMT?

TUMT provides significant symptom relief for most men with enlarged prostates, though it's generally considered less effective than surgical options like TURP. Studies show that about 60-80% of men experience meaningful improvement in their urinary symptoms after TUMT.

The treatment works best for men with moderate prostate enlargement and specific types of prostate anatomy. Your doctor will evaluate whether you're a good candidate based on your prostate size, shape, and the severity of your symptoms.

Long-term success rates show that many men maintain their improvement for several years after treatment. However, since the prostate can continue growing with age, some men may eventually need additional treatment. This is normal and doesn't mean the TUMT failed.

What are the risk factors for TUMT complications?

While TUMT is generally safe, certain factors can increase your risk of complications or affect how well the treatment works. Understanding these risk factors helps you and your doctor make the best decision for your situation.

Your overall health plays a significant role in how well you'll tolerate the procedure and recover afterward. Men with certain medical conditions may need special precautions or might not be ideal candidates for TUMT.

Factors that may increase complications include:

• Very large prostate glands (over 100 grams)
• Active urinary tract infections
• Severe heart conditions
• Blood clotting disorders
• Certain medications that affect healing
• Previous prostate surgery
• Severe bladder problems

Age alone isn't necessarily a risk factor, but older men may have multiple health conditions that need consideration. Your doctor will thoroughly evaluate your medical history to determine if TUMT is appropriate for you.

What are the possible complications of TUMT?

TUMT is considered a low-risk procedure, but like any medical treatment, it can have side effects and complications. Most complications are temporary and resolve on their own within a few weeks, but it's important to know what to expect.

The most common side effects are related to the healing process and typically improve as your prostate adjusts to the treatment. These effects are usually manageable and don't require additional treatment.

Common temporary side effects include:

• Burning sensation during urination for 1-2 weeks
• Increased urinary frequency initially
• Blood in urine for a few days
• Mild pelvic discomfort
• Temporary worsening of urinary symptoms

Less common but more serious complications can occur, though they're rare. These might require additional medical attention or treatment to resolve properly.

Rare complications include:

• Severe urinary retention requiring catheterization
• Urinary tract infection
• Significant bleeding
• Urethral stricture (narrowing)
• Need for additional procedures

Sexual side effects are generally less common with TUMT compared to other prostate treatments, but some men may experience temporary changes in ejaculation or erectile function.

When should I see a doctor after TUMT?

Regular follow-up care after TUMT is essential to monitor your healing and ensure the treatment is working effectively. Your doctor will schedule specific appointments, but you should also know when to seek immediate medical attention.

Most doctors recommend follow-up visits at 2 weeks, 6 weeks, and 3 months after your procedure. These appointments allow your doctor to track your progress and address any concerns that arise during recovery.

Contact your doctor promptly if you experience:

• Inability to urinate for more than 8 hours
• Fever over 101°F (38.3°C)
• Heavy bleeding or large blood clots
• Severe pain not controlled by prescribed medication
• Signs of infection like chills or burning that worsens

You should also reach out if your symptoms aren't improving after 6-8 weeks or if they seem to be getting worse instead of better. While some initial worsening is normal, persistent problems may need evaluation.
