[Ultrasonographic changes in prostatic tissue after thermotherapy]

The authors evaluated in 13 patients the peroperative and postoperative effect of thermotherapy by transrectal ultrasonography. In all patients for a period of 60 minutes by means of a transurethral cooled catheter a temperature of 50 degrees C was applied. In the two-dimensional B picture in all patients a hypoechogenic border round the urethra was observed which gradually became defined as a canal of varying width. Changes in the blood supply of the prostate were not detected by the authors. The functional equivalent of these changes was an improved uroflowmertric finding and IPPS score.
