[Autonomic nerve preserving operation for rectal carcinoma: preliminary postoperative urinary function of 15 cases]

The autonomic nerve preserving operation was performed on 15 patients with rectal carcinoma (9 men and 6 women), from August 1990 to February 1991. The average age was 57.2 years ranging from 28 to 70 years. Low anterior resection was performed on 6 patients having middle rectal carcinoma. Seven Colonic anastomosis and two abdominoperineal resections were performed for lower rectal carcinoma. The average operation time was 4 hours and 22 minutes. The average blood loss was 1560 cc. Urinary functions were evaluated pre- and post-operatively. None of the patients needed re-catheterization postoperatively. Urodynamic studies showed no significant differences. We recommend this operation for rectal cancer because it prevented the postoperative autonomic dysfunction without affecting the curability.
