[The background factors influencing loss of sexual intercourse after transurethral resection of the prostate (TUR-P)--A study using the Sapporo Medical University-Questionnaire].
BACKGROUND
Sexual dysfunction after transurethral resection of the prostate (TUR-P) depends on multiple factors including preoperative erectile function itself. Using the Sapporo Medical University-questionnaire, we analyzed background factors contributing to loss of sexual intercourse after the operation.


METHODS
We sent the self-administered questionnaires to 1,000 patients who had received TUR-P. Answers to questions were ranked as scores. Multiple regression analysis was used to identify factors significant for loss intercourse after TUR-P.


RESULTS
The response rate was 63.5%. Patient with incomplete answers and those having diseases affecting voiding or sexual function and antiandrogen medication were excluded from the study. Leaving 536 patients for the final analysis. Scores for sexual desire and erectile function in the patients who received TUR-P were lower than those of age-matched healthy males. When we divided the patients according to frequency of sexual intercourse before and after TUR-P, there was distinct differences in age, scores for sensory disturbance, depression, the cooperative value of the sexual partner, sexual desire, erectile function, nocturia, residual sensation and urgency between those maintaining sexual intercourse and those having lost it. Multiple regression analysis using these factors indicated that the scores of erectile function was the most significant determinant for maintaining sexual intercourse after TUR-P in patients aged from 50 to 69 years, followed by the cooperative value of the sexual partner, residual sensation and sensory disturbance. In those 70 old and older, the score for erectile function was the most significant determinant, followed by the cooperative value of sexual partner.


CONCLUSIONS
Our results suggest that, irrespective of age, the cooperation of the patient's sexual partner as well as erectile function significantly influence the maintenance of sexual intercourse after TUR-P. In addition, voiding condition and psychological status after TUR-P may affect the maintenance of sexual intercourse in patients in their fifties and sixties.
