Primary transitional cell carcinoma in vesical diverticula.
OBJECTIVE
To evaluate the treatment and prognosis of primary tumors in bladder diverticula.


METHODS
The cases of 611 patients treated for bladder tumors at a single medical center were retrospectively reviewed.


RESULTS
Eight patients had primary intradiverticular transitional cell carcinoma. Five patients had Stage Ta tumor, and 3 had Stage T1 tumor. Most patients were treated by local resection and adjuvant intravesical chemotherapy. All patients with initial Ta disease are disease free at the time of this writing. One patient with T1 disease died, 1 patient's disease recurred several times, and 1 patient showed positive cytology without apparent disease.


CONCLUSIONS
Superficial intradiverticular tumors may be treated conservatively. Routine cystoscopy for patients with a bladder diverticulum is warranted for early diagnosis of possible intradiverticular tumor.
