[Microwave transurethral thermotherapy in the treatment of prostatic adenoma].
We report 195 patients with prostatic adenoma treated with microwave transurethral thermotherapy. All patients were initially subjected to a clinical assessment including Madsen-Iversen symptom score, digital rectal examination, measurement of urine flow rate and residual urine volume, transrectal prostatic ultrasound examination and blood prostate specific antigen determination. A prostatron machine was used, installing an urethral probe under local anesthesia. Endourethral and rectal temperatures were simultaneously measured and the procedure was controlled by a special software. The treatment was performed in an outpatient basis with a single procedures that lasted 60 min. Of 31 patients with chronic urinary retention, 28 were left voiding spontaneously, without urethral catheters and 84% of 164 symptomatic patients were relieved. No complications occurred, although 31.1% of patients has a transitory urinary retention after the procedure. It is concluded that microwave thermotherapy is a good therapeutic alternative for prostatic adenoma.
