Transrectal ultrasonography was used to evaluate 54 patients with localized prostatic carcinoma treated with neodymium-YAG laser irradiation. Both pre- and postirradiation scans were obtained in 30 patients, while additional 24 cases were examined after laser irradiation only. The procedure represents a valuable contribution to proper preoperative staging and is mandatory for the follow-up of patients selected for this particular treatment. The shrinkage of the capsule is negligible after laser irradiation. No specific ultrasonic changes due to the laser effect are to be found. Abnormal parenchymal echoes and capsular irregularities are the major parameters indicating early recurrence of disease. The presence of malignancy must be confirmed by biopsy.
经直肠超声检查用于评估54例接受钕钇铝石榴石激光照射治疗的局限性前列腺癌患者。30例患者在照射前和照射后均进行了扫描，另外24例仅在激光照射后进行了检查。该检查方法对准确的术前分期有重要作用，对于选择这种特殊治疗的患者随访是必不可少的。激光照射后包膜的收缩可忽略不计。未发现因激光效应引起的特异性超声改变。实质回声异常和包膜不规则是提示疾病早期复发的主要参数。恶性肿瘤的存在必须通过活检来证实。
