Purpose: The aim of this study was to assess the safety of TME with pelvic autonomic nerve preservation in male rectal cancer patients in terms of voiding and sexual function.
Methods: We performed uroflowmetry using Urodyn (Dantec, Denmark) and a standard questionnaire employing the IIEF (International Index of Erectile Function) and the IPSS (International Prostate Symptom Score) pre- and postoperatively in 68 male rectal cancer patients.
Results: There were significant differences of mean maximal flow rate and voided volume before and after surgery (18.9±5.7 vs 13.7±7.0, 240±91.9 vs 143±78, P＜0.05, P＜0.05), respectively. But, there was no difference of residual volume before and after surgery (4.4±2.6 vs 8.1±4.4, P＞0.05). The total IPSS (International Prostate Symptom Score) was increased after surgery from 6.2±5.8 to 9.8±5.9 (P＜0.05). There were no changes of score for one of each seven IPSS items in from 49 patients (73.5 percent) to 61 patients (89.7 percent). Five IIEF (International Index of Erectile Function) domain score (erectile function, intercourse satisfaction, orgasmic function, sexual desire and overall satisfaction) was statistically decreased after surgery (18.2±9.3 vs 13.5±9.0, 8.4±4.2 vs. 4.4±2.9, 5.8±2.9, vs. 4.4±2.9, 6.1±2.4 vs. 4.8±2.0, 6.1±2.2 vs. 4.5±2.3, P＜0.05, respectively. Erection was possible in 55 patients (80.9 percent), but penetration ability was possible in 51 patients (75 percent). Complete inability for erection and intercourse was observed in 3 patients (5.5 percent). Retrograde ejaculation was noted in 9 patients (13.2 percent). IIEF domains such as sexual desire and overall satisfaction were markedly decreased in 39 patients (57.4 percent), 43 patients (63.2 percent), espectively. Multiple regression analysis of factors affecting postoperative sexual dysfunction showed that over 60 years (sexual desire: P=0.019), within 6 months (erectile function: P=0.04, intercourse satisfaction: P=0.011, orgasmic function: P=0.03), lower rectal cancer (erectile function: P=0.02, intercourse satisfaction: P=0.036, orgasmic function: P=0.027) were significant factors.
Conclusions: TME with pelvic autonomic nerve preservation technique showed a safety and comparable data in preserving sexual and voiding function. The IPSS and IIEF questionnaire were useful and more investigative in assessing urinary and sexual function.
