Abstract
We evaluate changes in sexual function in patients treated with high energy transurethral microwave thermotherapy compared to transurethral resection of the prostate. A total of 147 patients randomized to undergo transurethral microwave thermotherapy or transurethral resection of the prostate were asked to complete a self-administered questionnaire evaluating sexual function before, and 3 and 12 months after treatment. The questionnaire dealt with such items as social status, libido, quality of erection, ejaculation and overall satisfaction of sexual functioning. There was a statistically significant improvement of micturition in both groups. The improvement in the transurethral prostatic resection group was significantly better than in the transurethral microwave thermotherapy group. Antegrade ejaculation occurred at 3 months following treatment in 27% of the transurethral prostatic resection group compared to 74% of the transurethral microwave thermotherapy group and at 1 year in 37 and 67%, respectively. Significantly more patients undergoing transurethral prostatic resection (36%) had changes in sexual function compared to the transurethral microwave thermotherapy group (17%). The transurethral microwave thermotherapy group was more satisfied with the sex life. Of these patients 55% graded sex as very satisfying compared to 21% in the transurethral prostatic resection group. The severity of symptoms was not correlated with sexual function in this study. In general, older patients had sexual dysfunction more often, while younger patients had pain during sexual activities more frequently. Although clinically less effective, high energy transurethral microwave thermotherapy is a better therapeutic option than surgery for patients who want to preserve sexual function. In particular ejaculation is often preserved after transurethral microwave thermotherapy while there is significant deterioration following transurethral prostatic resection. In general, older patients have greater sexual dysfunction.
