Preservation of the anterior vaginal wall during female radical cystectomy with orthotopic urinary diversion: technique and results.

PURPOSE: Orthotopic urinary reconstruction has been shown to be a viable option in women undergoing radical cystectomy. However, due to anatomical differences and technical considerations orthotopic diversion has been performed in a relatively small number of patients. We examined our technique of vaginal wall preservation during female radical cystectomy and orthotopic neobladder construction.

MATERIALS AND METHODS: We reviewed the records of all patients who underwent radical cystectomy between January 1994 and December 2001. Of these 542 patients we identified 94 females, of whom 25 (27%) underwent orthotopic neobladder substitution. We reviewed perioperative major and minor complications, postoperative care, followup and pathological results.

RESULTS: Overall 21 of the 25 patients (84%) underwent anterior vaginal wall sparing. Five patients (24%) had minor complications, there were no major perioperative complications and no patients required transfusion. Median estimated blood loss in this group was 575 ml. (range 200 to 1,250). A single neobladder-vaginal fistula developed in a patient early in our series in whom the anterior vaginal wall was incised and repaired during dissection. Of the 21 patients 15 (72%) were continent. Pathological specimens revealed a negative posterior bladder wall and urethral margins in all cases. At a median followup of 12 months 1 patient had local recurrence.

CONCLUSIONS: Anterior vaginal wall preservation in female radical cystectomy with orthotopic neobladder substitution is technically feasible, maintains vaginal length and support, has an acceptable complication rate and can achieve negative margins. Prospective evaluation is needed to assess the long-term impact on functional outcomes and cancer control.
