The risk of urethral tumors in female bladder cancer: can the urethra be used for orthotopic reconstruction of the lower urinary tract?
We studied the risk of synchronous or secondary urethral tumors after long-term followup in women with bladder cancer. The charts of women treated for various stages of bladder cancer between 1973 and 1992 were reviewed. Of 356 evaluable patients 268 presented initially with primary and 78 with multilocular tumor involvement. There were 498 episodes of recurrent tumors in 127 patients, and a total 1,210 tumor locations in 854 primary and recurrent episodes of bladder cancer. Mean followup for these patients was 5.5 years (range 0.05 to 33.1). Overall 7 of 356 patients (2%) had urethral tumor involvement, all at initial presentation. Statistical comparison of various defined tumor localizations in the bladder revealed that the bladder neck (p < 0.000) and trigone (p < 0.035) were significantly more often the region of primary tumor occurrence in the urethral tumor group. All patients with secondary urethral tumors had tumor involvement of the bladder neck at the same time. A 1% urethral tumor involvement was seen among 104 patients with clinical stage T2 to 3b, N0, M0 transitional cell carcinoma, who could have been considered for curative radical cystectomy. No patient presenting with tumor recurrence regardless of its location was found to have urethral tumors. Subtotal urethrectomy is an option in select female patients after cystectomy for localized bladder cancer to allow orthotopic reconstruction of the lower urinary tract provided the bladder neck is free of tumor.
