En bloc transurethral resection of bladder tumors: use and limits

Abstract

Objectives: To evaluate the feasibility and safety of transurethral en bloc resection of bladder tumors using a flat loop. Transurethral en bloc resection of bladder tumors facilitates pathologic evaluation.

Methods: A total of 37 patients with papillary transitional cell carcinoma of the bladder underwent transurethral en bloc resection with the use of a flat loop electrode.

Results: In 37 patients, 62 lesions were removed using a flat loop to perform the en bloc technique. This method is safe to perform in the case of papillary tumors with a diameter of up to 25 mm and that are found in specific areas of the bladder.

Conclusions: It is both safe and feasible to perform en bloc resection with a flat loop electrode but attention must be paid to the limitations of this technique. Excellent pathologic evaluation of the grade and stage of the removed specimen is possible.
