作者对在肾盂恶性肿瘤和肾梗阻病人中应用介入性放射学技术的经验作了回顾。对象为22例因恶性输尿管梗阻而行经皮肾造口术的病人。由超声扫描和IVU确定梗阻侧和梗阻水平,所有病变均经活检证实。肾造口术在局麻、俯卧斜位、透视引导下按标准技术进行,两侧梗阻者常只选超声和IVU检查认为肾功能较好的一侧做肾造口。一般在肾上极或中极的后盏作穿刺,而后将引流管保留在肾盂或
The authors review the experience with the use of interventional radiology in patients with renal pelvis malignancies and renal obstruction. The subjects were 22 patients with percutaneous nephrostomy due to malignant ureteral obstruction. The level of obstruction and obstruction was determined by ultrasound scan and IVU, and all lesions were confirmed by biopsy. Renal ostomy in local anesthesia, prone tilt, guided by the perspective of the standard techniques, both sides of the obstruction often only choose ultrasound and IVU examination that kidney function better side of the kidney stoma. Generally in the kidney pole or pole in the rear for puncture, and then the drainage tube remain in the renal pelvis or
