To determine the stages of bladder tumor, which is most important to plan an adequate therapy, a 16 gauge 230mm long modified Menghini (Surecut®) biopsy needle was guided transabdominally by ultrasound and a cystoscope to obtain the whole bladder tissue core.
In six cases, the muscle layer, the submucosal layer and the tumor tissue were obtained and pathologic staging of tumor was possible. However, in 4 other cases, tumor tissue only was obtained and staging was impossible. The bladder tumor in one case was diagnosed pT3b with Surecut tissue specimen, but after a combined treatment by radiation and chemotherapy, the second biopsy confirmed the absence of carcinoma because of tumor necrosis in the whole layer bladder tissue. Furthermore, the operation of total cystectomy also revealed no carcinoma anywhere in the bladder.
