OBJECTIVE To evaluate the frequency of urethral and prostatic lesions on cystectomy specimens for bladder tumour. METHODS This retrospective histological study was based on 260 specimens: radical cystectomies performed in 7 operative sites. The prostate and urethra were analysed in 3 planes (upper, middle and lower thirds). The apex was studied separately. Urethral invasion was identified by continuity of the tumour or by the presence of vesical CIS. RESULTS Urethral involvement is frequent (30.6% cases) essentially due to contiguous invasion (43/80). CIS is the second pathological association (44 urethral CIS/75 bladder CIS). Prostatic adenocarcinoma was present in 17.8% of cases with a Gleason score > 6 for 30% of lesions. CONCLUSIONS The high frequency of urethral and prostatic involvement does not justify preservation of the prostate during cystectomy. A serial prospective study should define the precise criteria able to minimize the risk of conservative surgery.
