Purpose: We evaluated the effects of surgery for rectal cancer on postoperative voiding and sexual function over the course of time.
Materials and Methods: Data from 28 patients who underwent autonomic nerve preserving rectal cancer surgery were retrospectively analyzed. Operations were performed between October 2005 and July 2007 and all patients were followed-up for more than 3 years. Preoperatively, all patients underwent urodynamic studies including uroflowmetry, and filled out the International Prostate Symptom Score (IPSS). The evaluation of sexual function consisted of Erectile Function domain score in International Index of Erectile Function (IIEF-EFD) and Ejaculation domain score in Male Sexual Health Questionnaire (MSHQ-EjD). Data from uroflowmetry and questionnaires were examined.
Results: At 3 years postoperatively the prostate volume was similar to the preoperative value (P=0.727). There were no statistically significant postoperative changes in the average maximum flow rate (15.9 ml/s vs. 16.2 ml/s, p=0.637) and post-void residual urine volume (34.7 ml vs. 36.8 ml, p=0.809). No statistically significant differences were observed in the IPSS (13.2 vs. 12.2, p=0.374). However, although pelvic autonomic nerve preservation have been performed, a significant proportion of rectal cancer patients suffer from sexual dysfunction and the average of IIEF-EFD and MSHQ-EjD scores was decreased postoperatively until 3 years (25.1 vs. 16.1 and 28.3 vs. 14.2 respectively, p<0.001).
Conclusions: Voiding function was not affected after autonomic nerve-preserving rectal cancer surgery, however sexual function was significantly aggravated. We recommend that the baseline genitourinary function should be evaluated before the treatment for male rectal cancer patients, and penile rehabilitation is necessary for their quality of life after treatment.
