Gray scale transrectal ultrasonography has proved to be a valuable adjunct in the evaluation of patients with tumors of the prostate and bladder. Its application in patients with prostatic disease is in the detection of early asymptomatic tumors, in the accurate staging of local disease and in the following of patients after the institution of specific treatment. Although it is not being used for the detection of bladder tumors the procedure is a reliable means to evaluate the degree of tumor invasion so that proper therapy can be instituted.
经直肠灰阶超声检查已被证明是评估前列腺和膀胱肿瘤患者的一项有价值的辅助手段。它在前列腺疾病患者中的应用在于检测早期无症状肿瘤、准确判断局部疾病的分期以及在采取特定治疗后对患者进行随访。虽然它并非用于检测膀胱肿瘤，但该检查是评估肿瘤浸润程度的可靠方法，以便能够采取适当的治疗措施。
