title: [Value of a second transurethral resection in the assessment and treatment of patients with bladder tumor].
abstract: OBJECTIVE
  To analyse the value of a second transurethral resection, repeated within 3 to 6 weeks after the initial resection, in the treatment and the classification of patients with bladder tumour.
  
  
  METHODS
  We analyse the results of 72 repeated transurethral resection in 23 (32%) patients with T1 G1-2 bladder tumor, 9 (12.5%) with T1 G3 tumor, 31 (43%) with T2a G2-3 tumor and 9 (12.5%) with T2b G2-3 tumor. The evaluated patients are not associated with CIS.
  
  
  RESULTS
  Of all 23 T1 G1-2 tumors, 13 (57%) had residual Ta T1 tumor and 1 (4%) T2 tumor. In this group, the second resection changed the treatment in 1 (4%) patient. Of all 9 T1 G3 tumors, 4 (44%) had residual T1 tumor and 1 (11%) T2 tumor. In this group the second resection changed the treatment in 1 (11%) patient. Of all 31 T2a G2-3 tumors, 5 (16%) had residual T1 tumor, 4 (13%) T2 tumor and 6 (19%) T3-T4 tumor. In this group, the second resection changed the treatment in 10 (32%) patient. Of all 9 T2b G2-3 tumors, 2 (22%) had residual T1 tumor, 1 (11%) T2 tumor and 2 (22%) T3-T4 tumor. In this group, the second resection changed the treatment in 3 (33%) patients.
  
  
  CONCLUSIONS
  In T1 G1-2 and T1 G3 tumors, a second transurethral resection detect residual tumor in 36% of patients and change the treatment in 6% of patients. In T2a-b tumors, a second transurethral resection detect residual tumor in 50% of patients and change the treatment in 33% of patients.
