Transurethral microwave thermotherapy(TUMT) is a new treatment modality for benign prostatic hyperplasia (BPH). Among those BPH patients who are treated by TUMT, 32 patients who are folowed up appropriately are selected to analyze the
effectiveness
of
TUMT. Patients were treated one time, for 1 jpir. without sedation on an outpatient basis. All patients tolerated the treatment well without secondary effect, Toxicity was mild, consisting of bladder spasm, urinary retention, dysuria, hematuria
and
urethral pain. Significant increase in urine flow rate(from 6.7ml/sec to 11.2ml/sec), decrease in post-void residual urine volume(from 82.2ml to 28.6ml) and decrease in frequency of nocturia(from 3.1 to 1.7) were observed. TUMT represents a safe
and
promising outpatient approach to treatment of BPH, particularly for patients who are not candidates for conventional surgical approaches because of medical or personal reasons.
