Ejaculatory dysfunction after transurethral microwave thermotherapy for treatment of benign prostatic hyperplasia.
The possibility of retrograde ejaculation or impotence after transurethral resection of the prostate has led to searches for other treatments for benign hyperplasia (BPH). Transurethral microwave thermotherapy (TUMT) was administered to 100 men with a mean age of 61 years and moderate to severe BPH in one 60-minute outpatient session without anesthesia. A urethral catheter was frequently maintained for 5 to 7 days to avoid urinary complaints. Of the 100 original patients, 79 were followed from 3 to 24 months (mean 7.3 months). The prostate volume, irritative and obstructive symptoms, residual urine volume, and urinary flow improved (P < 0.01). No systemic complications were encountered. There were minor complications such as epididymitis, urethral bleeding, and severe micturition discomfort within the first 30 days postoperatively. A total of 7 ejaculatory disorders occurred among 64 patients (11%), 6 complete absences and 1 retrograde ejaculation without recovery for more than 6 months. As TUMT is a fairly new method, further studies must be done to define its effectiveness and safety.
