The manner of presentation and tumour stage in 16 consecutive patients with renal carcinoma who were treated surgically between 1976 and 1980, and in 37 patients treated similarly between 1981 and 1985, were reviewed. Two patients (13%) were discovered incidentally between 1976 and 1980 compared with 13 (35%) between 1981 and 1985. The renal tumours were discovered incidentally at the time of intravenous urography (IVU), ultrasound, computed tomography (CT) and angiography. There were 13 stage I and two stage II lesions, as assessed pathologically after nephrectomy. The tumours were less than 6 cm in diameter. Thirteen of 15 patients are alive between 6 and 90 months after surgery. No patient died of renal carcinoma. Our data have shown an increase in the proportion of incidentally diagnosed cases. The routine use of intravenous urography, ultrasound and computed tomography has led to earlier diagnosis, lower stage and possibly longer survival in patients with incidentally detected renal carcinomas compared with patients where the diagnosis was suspected.
回顾了1976年至1980年间接受手术治疗的16例连续性肾癌患者以及1981年至1985年间接受类似治疗的37例患者的临床表现和肿瘤分期情况。1976年至1980年间有2例患者（13%）为偶然发现，而1981年至1985年间有13例（35%）为偶然发现。肾肿瘤是在静脉尿路造影（IVU）、超声、计算机断层扫描（CT）和血管造影检查时偶然发现的。经肾切除术后病理评估，有13例I期病变和2例II期病变。肿瘤直径小于6厘米。15例患者中有13例在术后6至90个月存活。无患者死于肾癌。我们的数据显示偶然诊断病例的比例有所增加。与疑似诊断的患者相比；静脉尿路造影、超声和计算机断层扫描的常规使用已使偶然发现的肾癌患者得以更早诊断、分期更低且可能存活时间更长。
