The use of orthotopic neobladders in women undergoing cystectomy for pelvic malignancy

Summary

Since June 1990, 21 women aged from 31 to 78 years (mean, 62 years) have undergone lower urinary tract reconstruction by means of an orthotopic Kock ileal reservoir following cystectomy. The indication for cystectomy included 15 patients with transitional-cell carcinoma of the bladder, 2 patients with urachal adenocarcinoma, 1 patient with cervical carcinoma, 1 patient with a mesenchymal tumor of endometrial origin, 1 patient with interstitial cystitis, and 1 patient with a fibrotic irradiated bladder. A total of four complications (two early and two late) have occurred in this group of patients. Excellent continence has been achieved during the day and night in 95% and 89% of the patients, respectively. In all, 16 of 20 patients void volitionally per urethra without a residual urine volume, whereas 4 patients require intermittent catheterization to empty the neobladder. All patients are completely satisfied. One patient died of metastatic transitional-cell carcinoma without a pelvic recurrence. Of the remaining 20 patients, 18 are currently alive without evidence of recurrent disease. Tumor recurrence has occurred in two patients: one patient with an extensive mesenchymal tumor developed a sigmoid recurrence necessitating conversion to a continent cutaneous diversion, and one patient developed a right iliac recurrence. This initial experience with lower urinary tract reconstruction in women has yielded extraordinary results, and we feel that the option of orthotopic reconstruction following cystectomy can safely be offered to selected female patients.
