The use of local anesthesia with N-DO injector (Physion) for transurethral resection (TUR) of bladder tumors and bladder mapping: preliminary results and cost-effectiveness analysis.

Objective: We evaluated feasibility of TUR of Ta-T1 TCC of the bladder or bladder mapping under local anesthesia using a Physion endoinjector to see if correct tumor staging was possible, to check patient tolerability, and to analyze cost-effectiveness.

Methods: Thirty patients with bladder tumors and 10 patients with hematuria and/or doubtful cytologies were treated in a day hospital setting. TUR or biopsies were performed after injecting lidocaine into the outer area of the lesion in the bladder at 2-3 sites under the mucosa.
