Detection of Carcinoma in the Post-Cystectomy Urethral Remnant by Flow Cytometric Analysis

Abstract
Following radical cystoprostatectomy for bladder cancer patients must be monirored for carcinoma of the urethral remnant. Cytological examination of urethral washings has proved to be a useful alternative to urethroscopy and urethrography. Urethral irrigation specimens also can be evaluated objectively by flow cytometry. In each of 4 patients in whom carcinoma developed in the urethral remnant analysis of urethral irrigation by flow cytometry was positive and comparable to results of urethral irrigation cytology. Flow cytometry is an objective and apparently reliable diagnostic test for malignancy in the urethral remnant.
