TAU and CT are, after cystoscopy, the two most largely used methods in the diagnosis and the staging of the bladder tumors. TRUS is mostly used in the pathologies of the prostate and the seminal vesicles. 38 patients (34 M and 4 F) suffering from bladder cancer are included in this study in the period from July 1995 to January 1997. They are evaluated with TAU, TRUS and CT in order to evaluate the sensitivity and the specificity of TRUS in the diagnosis and the stadiation of bladder tumors. The patients included in this study are divided in two subgroups as patients having superficial and infiltrating tumors according to pathologic stage after TURB or radical cystoprostatectomy. Specificity and sensitivity values, overstaging and undestaging rates are calculated for each group. In the superficial tumors, TAU had a sensitivity and specificity of 72.2%, while with CT these values were respectively 70% and 75%; in the infiltrating tumors, TAU presented sensitivity of 65% and specificity of 70% while CT presented respectively 72.2% and 77.5%. With TRUS these values were 88.8% and 94.4% in the superficial tumors and 90% and 95% in the infiltrating tumors. The method with the highest overstaging rate was CT with 33.3% while the ones with the highest understaging rates were TAU and CT with 22.2%. The sensitivity with TRUS was 100% in a total of 29 infiltrating and superficial tumors of the trigone while it was only 55.5% in the tumors of the lateral walls and the dome. With TAU these values were respectively 82.7% and 22.2%, with CT respectively 79.3% and 44.4%. The specificity with TRUS was 100% for the tumors of the lateral walls and 77.7% of the dome; with TAU these values were respectively 75.8% and 55.5% with CT 75.8% and 77.7%. In conclusion, TRUS may be used with a high sensitivity and specificity in the diagnosis and the stadiation of infiltrating and superficial bladder tumors situated at the peritrigonal zone and in the diagnosis of tumors situated in other regions of the bladder.
经尿道超声检查（TAU）和计算机断层扫描（CT）是膀胱镜检查后在膀胱肿瘤诊断和分期中使用最为广泛的两种方法。经直肠超声检查（TRUS）主要用于前列腺和精囊疾病。本研究纳入了1995年7月至1997年1月期间的38例膀胱癌患者（34例男性和4例女性）。对他们进行了TAU、TRUS和CT评估，以评价TRUS在膀胱肿瘤诊断和分期中的敏感性和特异性。根据经尿道膀胱肿瘤切除术（TURB）或根治性膀胱前列腺切除术后的病理分期，将本研究纳入的患者分为浅表性肿瘤患者和浸润性肿瘤患者两个亚组。计算每组的特异性和敏感性值、分期过高和分期过低率。在浅表性肿瘤中，TAU的敏感性和特异性分别为72.2%，而CT的这些值分别为70%和75%；在浸润性肿瘤中，TAU的敏感性为65%，特异性为70%，而CT分别为72.2%和77.5%。TRUS在浅表性肿瘤中的这些值分别为88.8%和94.4%，在浸润性肿瘤中分别为90%和95%。分期过高率最高的方法是CT，为33.3%，而分期过低率最高的是TAU和CT，均为22.2%。在总共29例三角区浸润性和浅表性肿瘤中，TRUS的敏感性为100%，而在侧壁和穹隆部肿瘤中仅为55.5%。TAU在这些肿瘤中的值分别为82.7%和22.2%，CT分别为79.3%和44.4%。TRUS对侧壁肿瘤的特异性为100%，对穹隆部肿瘤为77.7%；TAU在这些肿瘤中的值分别为75.8%和55.5%，CT为75.8%和77.7%。总之，TRUS在诊断和分期位于膀胱三角区周围的浸润性和浅表性膀胱肿瘤以及诊断位于膀胱其他区域的肿瘤时，可具有较高的敏感性和特异性。
