TEMPRO Bipolar RF Thermal Treatment for Abacterial Chronic Prostatitis

Byun, Jae Sang MD, , Byoung Kyu Han MD, Kihyuck Moon MD

Introduction and Objectives: 

Abacterial Chronic Prostatitis is a challenging illness in our day to day urology practice.  Patients undergo several types of treatments and many of them are not relieved of their pain. We have recently started a clinical trial using Bipolar Radiofrequency Thermal Treatment (Direx–Initia’s Tempro device) to treat Abacterial Chronic Prostatitis with our patients both young and old (27 to 72 years).We are here reporting our initial results with patients that have completed at least a three months follow up.

Material and Methods

We used the Tempro system (from Direx-Initia) with a treatment protocol of 55 degrees Celsius for 50 minutes, medium heating rate. All patients had tried different drugs, such as Ciproxin ,Tamsulosine and NSAID, without success.We utilized the NIH Symptoms Score in order to evaluate quantitatively patient improvements.

Results

The results after 3 months are as follows;

  Baseline CPSI score Post-TEMPRO  CPSI score p value
Mean Total score 23.4 ± 7.3 16.5 ± 4.9 0.072
Mean pain domain score 11.2 ± 5.4 6.5 ± 3.8 0.034
Mean Urination domain score 5.7 ± 3.3 5.2 ± 2.3 0.872
Mean Quality of life domain score 6.6 ± 2.4 4.6 ± 1.6 0.138
Taking a criteria of improvement as a 50% reduction in symptoms score the following Table shows the success  resultsTable 3. Subgroup analysis according to the decline of CPSI score more than 50 percent at 3 month after TEMPRO. - Group A : CPSI scores decreased more than 50% after TEMPRO  (= successful group) - Group B : CPSI scores does not decreased more than 50% after TEMPRO (= unsuccessful group)
  Group A Group B p value
 
Total Success 19 ( 46 % ) 22 ( 54 %)
