Abstract

From July, 1992 to June, 1993, 32 patients with BPH were treated with transurethral radio frequency thermotherapy(TURT) and 54 patients with transurethral microwave thermotherapy (TUMT). Of the patients 15 and 19 were followed for 3 month(range 2-6 months) and analysed to compare the effectiveness of TURT and TUMT respectively. Mean age was 70.3(range 55-88) and 68.7( 54-82) and mean prostatic weight was 30.3gm ( 14-52gm) and 33.8gm(11 -60gm). These patients were treated by one session for 1 hour. The improved response rate with TURT versus TUMT in residual urine volume and maximal flow rate were 40%, 57% and 47%, 32%. The improved response rate more than 6 points in modified Boyarsky symptom score were 73% and 63%. The side effects were urinary retention, dysuria, hematuria and perineal discomfort in both types. We conclude there were no differences in the effectiveness according to electromagnetic wave types and these transurethral thermotherapies are safe and simple method for patients who are not candidates for surgery because of medical illness or personal favorites.
