[Microwave hyperthermia for benign prostatic hyperplasia].
We treated 312 cases of benign prostatic hyperplasia (BPH) with 915 MHz microwave delivered transurethrally with a special applicator. All the 312 patients received a single thermal session (60 minutes). The temperature achieved in the prostate ranged from 43 to 45 C. Follow-up for 6 months showed that about 70.1% of the patients were subjectively improved and 37.0% had a increased flow rate, 43.0% gained a decreased residual urine. In 32 failure cases, 11 were due to median lobe hyperplasia, 4 diabetes mellitus, 4 cerebrovascular disease, and 13 miscellaneous. In the full retention group (39 patients), 21 had catheter removed 2-7 weeks after the thermal session. In this group, 27 patients encountered a side effect, including hematuria 23, fever 2, and acute retention 2, all of these patients were recovered rapidly.
