To establish an overview of computed tomography (CT)-guided percutaneous nephrostomy performed at a referral center for cancer, addressing the characteristics of patients submitted to this intervention, as well as the indications for it, the technical specificities of it, and its main complications.
This was a retrospective study involving a review of the electronic medical records and images of patients submitted to CT-guided percutaneous nephrostomy at a referral center for cancer between 2014 and 2016.
A total of 201 procedures were evaluated. In most cases, the obstruction was caused by a malignant neoplasm. Complications occurred in 9.5% of the cases, and an additional intervention was required (typically for catheter repositioning) in 36.6%. Post-procedure complications were not found to be significantly associated with the type of previous cancer treatment, the technique used, the caliber of the drain used in the procedure, or the degree of dilatation of the collection system prior to the procedure.
In cancer patients, CT-guided percutaneous nephrostomy is an effective treatment, with success rates and complication rates similar to those reported in the general population.
在一家癌症转诊中心对计算机断层扫描（CT）引导下经皮肾造瘘术进行概述，阐述接受该干预措施患者的特征、其适应证、技术特点及其主要并发症。
这是一项回顾性研究，涉及对2014年至2016年间在一家癌症转诊中心接受CT引导下经皮肾造瘘术患者的电子病历和影像进行回顾。
共评估了201例手术。在大多数情况下，梗阻由恶性肿瘤引起。9.5%的病例发生了并发症，36.6%的病例需要额外干预（通常用于导管重新定位）。术后并发症与既往癌症治疗类型、所使用的技术、手术中使用引流管的管径或手术前集合系统的扩张程度未发现显著相关性。
在癌症患者中，CT引导下经皮肾造瘘术是一种有效的治疗方法，成功率和并发症发生率与普通人群报告的相似。
