We assess the value and limitation of transurethral ultrasonography in the diagnostic evaluation of bladder carcinoma.
A total of 115 patients underwent the procedure, either at the same setting as transurethral resection (76) or 2 weeks before radical cystectomy (39). The results were compared with the pathological findings of transurethral and cystectomy specimens.
The correlation between transurethral ultrasonography and pathological staging was 100% in tumors without muscle invasion (stages Ta and T1), 95.7% and 96.8% in muscle invasive tumors (stages T2 and T3a, respectively), and 70% in tumors with extravesical spread.
Transurethral ultrasonography is most valuable in determining the stage of tumor confined to the bladder wall. Also, it is of value in detecting tumors in a diverticulum, and monitoring the distensibility of the bladder wall and transurethral resection of disease. The main limitations are the inabilities to discriminate between stages Ta and T1 tumors, and to detect involvement of the pelvic lymph nodes.
我们评估经尿道超声检查在膀胱癌诊断评估中的价值和局限性。
共有115例患者接受了该检查，其中76例与经尿道切除术在相同环境下进行，39例在根治性膀胱切除术2周前进行。将结果与经尿道和膀胱切除标本的病理结果进行比较。
在无肌层浸润的肿瘤（Ta和T1期）中，经尿道超声检查与病理分期的相关性为100%；在肌层浸润性肿瘤（分别为T2和T3a期）中，相关性分别为95.7%和96.8%；在有膀胱外扩散的肿瘤中，相关性为70%。
经尿道超声检查在确定局限于膀胱壁的肿瘤分期方面最有价值。此外，它在检测憩室内的肿瘤、监测膀胱壁的扩张性以及经尿道疾病切除方面也有价值。主要局限性在于无法区分Ta和T1期肿瘤，以及检测盆腔淋巴结受累情况。
