| | Objective:To evaluate the effect of focused extracorporeal pyrotherapy(FEP)for treating infiltrative bladder tumors.Methods:Eighteen patients with infiltrative bladder tumors were treated by FEP and followed up every 3 months.Results:Coagulative necrosis was observed in all patients immediately after treatment.Fiftern tumors(15/18,82 3%)were completely disappeared after treatment and 3 tumors(3/18,16 7%)were partially receded.Three infiltrated masses out of bladder were minimized about one third.One case ... | | 目的 :了解体外聚焦超声热疗 ( FEP)治疗浸润性膀胱肿瘤的疗效。方法 :本文共对 18例 T3期浸润性膀胱肿瘤进行 FEP治疗 ,分别于治疗前、后行膀胱 B超、盆腔 CT及 /或膀胱镜检 ,此后每 3个月复查一次。结果 :膀胱肿瘤治疗后均可见凝固性坏死改变 ,B超回声明显增强 ,18例患者出院时 15例膀胱内肿瘤消失 ( CR=83.3% ) ,3例肿瘤萎缩大于 2 /3 ( PR=16 .7% ) ,3例膀胱外浸润性包块萎缩约 1/3。 1例随访 2年 ,无复发 ,6例患者随访 12个月 ,1例复发。结论 :FEP可作为浸润性膀胱肿瘤的一种新的治疗方法 ,近期疗效显著。 | | 文摘来源 | | Objective To evaluate the clinical effect of high intensity focused ultrasound(HIFU) in treatment of patients with genitourinary tumors. Methods The study included 20 patients(Mean 67.8 years, Rane 44-79a) with genitourinary tumors were treated using extracorporeal HIFUdevice. Patients were followed up one month before and after HIFU, to observe the quality of life, relative symptoms, and take the transabdominal ultrasonography of computer tomgraphy to monitor tumor size and any complications. Results... | | 目的 探讨高强度聚焦超声对泌尿生殖系肿瘤治疗的疗效。 方法 应用高强度体外聚焦超声热疗机治疗泌尿生殖系肿瘤患者20例(年龄44~79岁,平均67.8岁),一个月随防,观察其生活质量,相关症状,B超、CT肿瘤大小变化和并发症。 结果 70%患者生活质量明显改善,症状明显减轻,且无严重并发症发生。 结论 高强度聚焦超声治疗泌尿生殖系肿瘤安全有效,产生副作用少。然而,控制好声强,照射时间和靶点定位是技术关键。 | | 文摘来源 | | Objective:To evaluate the clinical effect of high intensity focusing ultrasound(HIFU)for the treatment of metastatic carcinomas in pelvis and abdomen by observing the changes of color Doppler ultrasound imaging.Methods:Before and after HIFU,21tumors in15patients with metastases were examined by color Doppler ultrasound to observe changes in lesion size,the echo and color Doppler flow images and changes of the pathology after HIFU.Results:HIFU therapy can re-duce tumor size.The efficacy rate was76... | | 目的:评价高强度体外聚焦超声热疗(HIFU)治疗盆腹部转移癌的临床应用价值及彩色多普勒超声治疗前后声像图变化。方法:15例转移癌共21个癌瘤HIFU治疗前后均进行彩超检测,观察其大小、内部回声及血供改变情况,并观察HIFU治疗后癌瘤病理组织学改变。结果:治疗有效率76%(16?21)。治疗后彩超表现为癌瘤缩小,回声增强,血供明显减少或消失;病理组织学上表现为凝固性坏死或纤维化形成。结论:HIFU对盆腹部转移癌治疗有效。彩超能直观反映其疗效。 | | 文摘来源 | |   |
