目的:分析经皮肾镜超声碎石术治疗鹿角形结石的效果。方法:2009年1月~2014年6月期间,苏州大学附属第三医院共收治鹿角形结石患者105例,对其采取经皮肾镜超声碎石进行治疗,观察治疗效果。结果:一期手术结石取尽率为78.2%,二期手术结石取尽率为92.3%,所有患者均留置双J管和肾造瘘引流。平均住院天数为9.8d,平均手术时间为65min;平均术中失血量150mL。术后半年随访显示,无感染、出血、肾功能丧失、结石复发、肾周积液出现。结论:经皮肾镜超声碎石术能有效治疗鹿角状结石,有较高的碎石和清石率,手术时间较短,出血量少,是治疗肾脏鹿角状结石的首选方案。 相似文献

目的 总结膀胱副神经节瘤的临床病理学特征及诊疗方法.方法膀胱副神经节瘤2例.例1,女,35岁.临床表现排尿后心慌、头痛,B超及CT检查示膀胱左侧壁肿块2.6 cm×1.5cm,尿3-甲氧-4-羟苦杏仁酸(VMA)35.3~43.3 μmol/24 h(正常值10~35 μmol/24 h).例2,男,22岁.临床表现无痛性全程血尿,B超及CT检查示膀胱右前壁肿块2.5 cm× 2.0 cm,尿VMA 17.9~31.3 μmol/24 h.结果行经尿道膀胱肿瘤电切术1例,行膀胱部分切除术1例.病理诊断为膀胱副神经节瘤.免疫组化CgA、Syn、S-100蛋白和NSE(+).患者术后症状消失,行膀胱镜及B超分别随访3个月、3年肿瘤无复发.结论膀胱副神经节瘤为潜在恶性肿瘤,诊断需结合临床、病理及免疫组化结果判断,膀胱部分切除为主要治疗手段.Abstract: Objective To study the clinical,histopathological,immunohistochemical features and the diagnosis and treatment of paraganglioma of urinary bladder. Methods Two cases of paraganglioma of urinary bladder were treated. The first case was a male with painless haematuria. The abdominal ultrasonography and CT scan showed a 2.5 cm× 2.0 cm mass in the right anterior wall of the bladder, and urine vanillylmandelic acid elevated to 17. 9- 31. 3 μmol/24 h (normal range 10- 35 μmol/24 h). The second case was a female who presented with 8 years history of headache and palpitation after voiding. Abdominal ultrasonography and CT scan showed a 2. 6 cm× 1.5 cm mass in the left wall of the bladder, and her urine vanillylmandelic acid was 35.3-43.3 μmol/24 h. Results One patient underwent transurethral resection (TURBT) and the other underwent partial cystectomy.The two cases were diagnosed as bladder paraganglioma by pathological examination. Immunohistochemically, the tumor cells were positive for CgA, Syn, NSE and S-100. No evidence of recurrence was detected during follow-up at 3 months and 3 years. Conclusions Paraganglioma of urinary bladder should be considered as a low grade malignancy. Partial cystectomy should be recommended. The diagnosis depends on clinical symptoms, pathological and immunohistochemical results. 相似文献
