TUMT 2.0: results three months and three years after treatment.
OBJECTIVE
To examine the durability of the results following low-power transurethral microwave thermotherapy (TUMT).


METHODS
28 patients 55 to 83 years of age with lower urinary tract symptoms (LUTS) and marginal/moderate infravesical obstruction and 4 patients with LUTS, peak urinary flow (Qmax) less than than 15 ml/sec and prostate volume below 40 ml. We used a Prostatron version 2.0.


RESULTS
transurethral resection of the prostate (TURP) was done shortly after treatment in one patient with acute obstruction caused by necrotic tissue. Three months after treatment 15 patients reported that they were cured from LUTS and 10 experienced improvement of symptoms. A significant reduction of the symptom scores was seen among the 31 patients not operated while Qmax was unchanged. Three years after treatment two patients were still cured from LUTS, 9 hadsome reduction of symptoms, and TURP had been done in further three patients. Symptom scores among the 24 patients still in the study were significantly lower than the baseline values but also significantly higher than the symptom scores three months after treatment. Residual urine was reduced while no changes were seen in Qmax.


CONCLUSIONS
TUMT done by Prostatron version 2.0 causes mainly a reduction of symptoms. Most of the effect disappears after a few years.
