膀胱平滑肌瘤是一种罕见的间叶组织来源良性肿瘤,华中科技大学同济医学院附属同济医院泌尿外科于2018年8月收治1例巨大膀胱平滑肌瘤患者,采用经尿道激光剜除术治疗,取得满意疗效,现报告如下. 患者,男,70岁,排尿中断伴下腹部胀痛3月余,伴有尿频、尿急症状,偶有肉眼血尿,血尿症状能自行缓解,无发热及腰痛.既往2年前因前列腺增生症行前列腺激光剜除术,术后恢复良好.入院体格检查及 PSA未见明显异常.全腹部增强CT提示膀胱尿道内口处见不规则团块状软组织密度影,突向膀胱腔内,边界可见散在高密度钙化灶,增强不均匀强化,大小约55 mm×46 mm ×62 mm ,腹膜后及盆壁未见肿大淋巴结影(图1). MRI平扫+DWI提示膀胱左前壁可见菜花样稍长T1 稍长 T2 信号,可见低信号"蒂"影,DWI弥散明显受限,肌层未见明显侵及,盆腔内未见肿大淋巴结(图2) .经尿道膀胱镜检查提示膀胱颈口可见巨大新生物,类圆形,表面光滑,基底部位于膀胱颈左上方,因肿瘤遮挡,双侧输尿管口无法窥及.膀胱镜病理活检:梭形细胞肿瘤,结合免疫组化,考虑平滑肌来源;免疫组化:EM A (+) ,DES (+) ,CaLdesmon(+) ,SDHB (+) ,SMA (弱+) ,ALK (散在+) ,CD117(－) ,CD34 (－) ,DOG1 (－) ,S‐100 (－) ,SOX10 (－) ,ST A T6 (－) ,PCK (－) ,GAT A‐3 (－) ,HMB45 (－) , MeLanA (－) ,Ki‐67 LI约5%.

This paper describes the microwave(MW)treatment of soil contaminated by chloramphenicol(CAP).Four MW absorbents,including granular activated carbon(GAC),powdered Fe,MnO2 and H2O,were used.The catalytic effect of the four MW absorbents follow the order of GACFeH2OMnO2.The mineral substance in the soil(such as Fe)can be used as MW absorbent,to reduce the remediation cost.It is suggested that MW radiation is an alternative technology for the treatment of antibiotics-contaminated soils.
