[Transurethral microwave thermotherapy. A therapeutic option for high-risk patients with urinary retention secondary...

Urinary retention secondary to benign prostatic hyperplasia is considered an absolute indication for surgical treatment of the prostate. Transurethral resection of the prostate is still considered the gold standard in terms of effectiveness. One of several new techniques for treatment of BPH is transurethral microwave thermotherapy (TUMT). Our first experiences with this technique in a group of patients with urinary retention were analysed retrospectively. In the short term 16 of the 25 treated patients were able to void spontaneously with acceptable bladder emptying (64%, 95% CI: 43-85). Later on, three of these initial successes received further treatments for BPH, two had a transurethral resection of the prostate and one was given medical therapy. No serious complication was seen except in one patient who developed a urethrorectal fistula which healed following conservative treatment. The success rate following TUMT was inferior to that of standard transurethral resection, but TUMT seems an acceptable alternative in patients with pronounced co-morbidity.
