Introduction: Erectile dysfunction significantly affects health-related quality of life. Even if a patient can function sexually after radical prostatectomy, he may not be able to take part in sexual intercourse; thus, sexual function may be perceived to have decreased. We evaluated the frequency of sexual intercourse and sexual activities of patients after undergoing robot-assisted laparoscopic radical prostatectomy (RALP).
Methods: We prospectively obtained one-year longitudinal the Expanded Prostate Cancer Index Composite (EPIC) data (preoperative and at 3, 6, 9, and 12 months after RALP) from 300 patients. We classified the frequency of sexual intercourse and activities as &[Prime]Not at all&[Prime], &[Prime]Less than once a week&[Prime], &[Prime]About once a week&[Prime], &[Prime]Several times a week&[Prime], and &[Prime]Daily&[Prime].
Results: The percentages of patients who took part in sexual activity before undergoing RALP and 3, 6, 9, and 12 months after RALP were 47, 23, 29, 31, and 34%, respectively. Those of patients who took part in sexual intercourse before undergoing RALP and 3, 6, 9, and 12 months after RALP were 33, 6, 10, 10, and 10%, respectively. Both sets of values after undergoing RALP were significantly lower than those before undergoing RALP (Fig.1). Sexual activity was not associated with the improvement of sexual function in Sexual Health Inventory for Men (SHIM) score. On the other hand, sexual activity was associated with the improvement of sexual function in EPIC score as with sexual intercourse (Fig.2).
Conclusions: There was a large discrepancy between the percentages of patients taking part in sexual intercourse and sexual other activities; therefore, we should consider not only sexual intercourse but also sexual activities when evaluating normal sexual function in patients with localized prostate cancer after RALP.
