Evaluation of the sexual consequences of surgery: retrospective and prospective strategies.

To assess the impact of a stressor, it is desirable to evaluate affected individuals' status both prior to and following a stressful event. Because of the difficulties inherent in prospective designs, investigators often ask people who have experienced an aversive event to evaluate their prestressor adjustment retrospectively. Do such retrospective evaluations provide a reasonable alternative to prospective assessment? To answer this question we compared retrospective and prospective data gathering procedures in the evaluation of sexual adjustment after prostate surgery. One hundred fifty-two married males who had undergone prostatectomy for benign prostatic enlargement completed a battery of measures which evaluated pre- and postsurgical sexual adjustment either prospectively (i.e., before and after surgery) or retrospectively (i.e., ratings made after surgery of both pre- and postsurgical adjustment). Retrospective assessment indicated considerable sexual deterioration pre- to postsurgery. In subjects tested prospectively, however, the results showed that surgery had little impact on sexual adjustment. Moreover, direct comparisons of retrospective and prospective methodologies reveal that discrepancies are due to differences in evaluations of presurgery status, with retrospective evaluation yielding more favorable ratings than prospective assessment. The results highlight a variety of biases which may affect self-ratings of pre- and post-stressor adaptation and show that discrepancies associated with the two methodologies have important implications for understanding the impact of a stressor on adjustment.

Prostatectomy and inguinal hernia repair: a comparison of the sexual consequences.

This study investigated whether psychosexual changes found after surgery for benign prostatic enlargement relate specifically to the prostatectomy procedure or to the stresses of surgery in general. The sexual adjustment of 91 married men (ranging in age from 51 to 77) who had undergone either transurethral prostatectomy or inguinal hernia repair was compared using the same measures and experimental design. Results show that both surgeries appeared to result in relatively minor but widespread negative consequences for sexual adjustment and expression. Findings on both individual and couple sexual adjustment suggest that the psychosexual consequences of the two procedures do not differ substantially. As expected, the one exception was retrograde ejaculation, which was more likely to be experienced by men who had undergone prostate surgery. The results illustrate the necessity of conducting comparative studies when evaluating the sexual consequences of surgical procedures and highlight the importance of taking age into consideration when conducting research on the effects of surgery on older men.
