OBJECTIVE: Bladder dysfunction caused by autonomic nerve injury is a well-recognized complication of pelvic surgery. Modified posterior exenteration with or without nerve preservation was performed in patients with primary ovarian, tubal, peritoneal, and endometrial cancer. The aim of this retrospective study was to evaluate the impact of this surgical technique on bladder function. METHODS: Among the 60 consecutive patients in whom modified posterior exenteration was performed, bilateral and unilateral nerve-sparing surgeries were performed in 43 (72%) and 15 (25%) patients, respectively. In the remaining 2 patients (3%), the pelvic autonomic nerves on both sides were sacrificed. Symptoms and bladder function after bilateral or unilateral nerve-sparing surgery were analyzed using standardized questionnaires before and 3 and 6 months after surgery. RESULTS: All patients with bilateral nerve-sparing surgery had sufficient micturition from the early postoperative period. Though 40% of the patients with unilateral nerve-sparing surgery had difficulty in spontaneous voiding and needed intermittent catheterization, voiding ability of them improved and no self-catheterization was required 3 months after surgery. The assessment of patient questionnaires suggested that bladder function was acceptable in both groups at 6 months. Patients with bilateral nerve-sacrificing surgery complained of neurogenic bladder requiring self-catheterization even 6 months after surgery. CONCLUSIONS: This preliminary study showed that preservation of bladder function after modified posterior exenteration was feasible with a nerve sparing approach and that standardized outcome measures could be used to monitor this. However, careful follow-up is required. Future larger studies are needed to investigate pelvic autonomic nerve function.
