Cooled ThermoTherapy™/TUMT™ reduce BPH symptoms, preserves sexual function, and provides durable results using the Targis® system. Treatment can be completed within 45 minutes, usually does not require anesthesia, and is performed in a physician’s office or an outpatient setting.
In this treatment, a specially designed antenna inside a catheter is inserted into the prostate through the urethra. This antenna is used to direct microwave energy into the prostate to heat and destroy enlarged tissue. During the procedure, cool water is circulated through the catheter to minimize patient discomfort, protect adjacent urethral tissues from excessive temperatures, and reduce the risk for serious side effects.
Medication is often administered to reduce discomfort and help patients relax during the procedure. Many patients are able to read, watch television, or listen to music during treatment and some may experience the following:
1. Bladder spasms
2. Pressure in the rectum
3. Sensation of needing to empty the bladder or have a bowel movement
4. Warm or burning sensation in the abdomen or penis
Following treatment, anti-inflammatory medication and antibiotics may be prescribed. Most patients can resume normal activity immediately after treatment. Destroyed prostatic tissue is reabsorbed by the body or discharged in the urine over the course of 6 to 12 weeks and BPH symptoms gradually improve during this time.
Side effects usually resolve without intervention within a few weeks of treatment and include the following:
1. Frequent urination
2. Pink discharge in the urine or around the catheter
3. Soreness in the lower abdomen
4. Urethral inflammation and swelling (most patients require catheterization for 2–5 days)
5. Urgency (even after removal of the catheter)
Prolieve™ Thermodilatation System is a transurethral microwave thermotherapy (TUMT) device that also uses a special balloon catheter to open up (dilate) the urethra, as well as microwave energy to heat and destroy enlarged prostatic tissue. In this procedure, the balloon catheter is filled with warm water. After the temperature of the tissue returns to normal, the urethra remains open. Prolieve™, which takes about 45 minutes, is performed in a physician’s office under local anesthesia. In a recent study, about 5% of patients required catheterization following the procedure.
