[Intradiverticular tumors of the bladder: diagnostic and therapeutic problems about 32 cases]

ABSTRACT

The transitional cell carcinoma within the bladder diverticular is a rare and poorly known entity. To evaluate diagnostic and therapeutic approaches of transitional cell carcinoma within the bladder diverticular. Thirty men and two women [median 70 years; 44- 83 years] were included. The main reason for consultation was hematuria. The intra-diverticular tumor was suspected by radiological assessment in 9 patients only. All these patients underwent an endoscopic resection of the tumor. The histological study concluded to a pta stage in 16 patients, pt1 stage in 8 patients and invasive tumors in 8 patients. A complementary endovesical BCG-therapy was performed in patients with superficial tumors and a radical cystectomy in patients with invasive tumors. With an average follow-up of 27 months, seven recurrences were found in the group of superficial tumors, including 3 cases of progression to invasive stage. Bladder intra-diverticular tumors are rare and more common in elderly. In a bladder diverticulum, there are superficial tumors [pta, pt1] which are the most frequent and invasive tumors. Radical cystectomy is the gold standard for invasive tumors.Endoscopic resection combined with endo-vesical immunotherapy should be reserved for superficial tumors
