The more liberal use of ultrasonography and computed tomography has made more common the incidental discovery of renal masses. The charts of 105 patients surgically treated for renal cell carcinoma at a teaching hospital from 1983 to 1987 were reviewed. The incidence of incidentally found asymptomatic tumors was 47% (49/105 patients). Of the incidentally found tumors, 55% were stage I and only 14% were stage III; for symptomatic patients, 39% of tumors were stage I and 27% were stage III. This study also found that the classical triad of pain, hematuria, and flank mass was present in only 3.8% (4/105) of patients. Tumors found incidentally will usually be of lower pathologic stage and may carry a better prognosis.
超声检查和计算机断层扫描的更广泛应用使肾脏肿块的偶然发现更为常见。回顾了1983年至1987年在一家教学医院接受手术治疗的105例肾细胞癌患者的病历。偶然发现的无症状肿瘤的发生率为47%（49/105例患者）。在偶然发现的肿瘤中，55%为I期，仅14%为III期；对于有症状的患者，39%的肿瘤为I期，27%为III期。该研究还发现，仅3.8%（4/105）的患者出现了疼痛、血尿和侧腹肿块这一经典三联征。偶然发现的肿瘤通常病理分期较低，预后可能较好。
