The role of a routine second transurethral resection in evaluating and managing bladder tumors is defined.
From January to October 1998, 150 patients with new or recurrent bladder tumors underwent repeat transurethral resection within 2 to 6 weeks after the initial resection, and the results, including the presence of residual tumor and tumor stage, were compared.
Of the 150 cases 36 (24%) had no and 114 (76%) had residual tumor on repeat transurethral resection. Of 96 cases with superficial (Ta, Tis, T1) bladder tumors 72 (75%) had residual noninvasive tumor and 28 (29%) were up staged to invasive tumor. Among 54 patients with a muscle invasive tumor 12 (22%) had no residual tumor on repeat transurethral resection. Results of the second resection changed tumor treatment in 50 patients (33%).
Many patients with bladder tumors have tumor present after an initial trans-urethral resection. Routine repeat resection is advised to control noninvasive tumors and to detect residual tumor invasion.
明确常规二次经尿道切除术在评估和处理膀胱肿瘤中的作用。
1998年1月至10月，150例新发或复发性膀胱肿瘤患者在初次切除术后2至6周内接受了再次经尿道切除术，并对结果进行比较，包括残余肿瘤的存在情况和肿瘤分期。
150例患者中，36例（24%）再次经尿道切除术后无残余肿瘤，114例（76%）有残余肿瘤。96例浅表性（Ta、Tis、T1）膀胱肿瘤患者中，72例（75%）有残余非浸润性肿瘤，28例（29%）肿瘤分期上升为浸润性肿瘤。54例肌层浸润性肿瘤患者中，12例（22%）再次经尿道切除术后无残余肿瘤。二次切除结果改变了50例患者（33%）的肿瘤治疗方案。
许多膀胱肿瘤患者在初次经尿道切除术后仍有肿瘤残留。建议进行常规重复切除以控制非浸润性肿瘤并检测残余肿瘤浸润情况。
