Abstract

BACKGROUND:

This study aimed to compare voiding and male sexual dysfunction between open and laparoscopic rectal cancer surgery.

METHODS:

Ninety-seven patients (62 male and 35 female) who underwent open (n = 41) or laparoscopic (n = 56) surgery for rectal cancer were prospectively enrolled. Urine flowmetry, the international prostate symptom score, and the international index of erectile function were assessed preoperatively and postoperatively.

RESULTS:

Voiding function score increased 1 month after surgery (open: 9.3 ± 4.6 to 14.0 ± 8.2, laparoscopic: 8.3 ± 5.3 to 12.3 ± 5.2; P = 0.002 and P < 0.001). The score was even higher in both groups after 6 months, but the increases were not statistically significant (open: 9.9 ± 4.5, laparoscopic: 9.2 ± 5.6; P = 0.546 and P = 0.280). Male patients who underwent open surgery (n = 22) experienced declining sexual function until 12 months post surgery (before: 55.2 ± 9.8, 12 months: 48.7 ± 15.9, P = 0.031). In laparoscopic group (n = 28), sexual function decreased until 6 months after surgery, but rose again by 12 months (before: 55.4 ± 9.0, 12 months: 52.2 ± 11.7, P = 0.134).

CONCLUSIONS:

Voiding dysfunction recovered after 6 months following both open and laparoscopic surgery. Male sexual function recovered more quickly in laparoscopic group and returned to preoperative levels after 12 months.
