This study aimed to describe and evaluate a real-time ultrasound-guided (US-guided) drainage technique for effective and safe drainage of gas-forming renal abscesses (GRA) in an intensive care unit(ICU).
This retrospective study included four patients with GRA who were admitted to the ICU of a tertiary care center between September 2021 and September 2023. The patients were all comorbid with severe systemic infections and required drainage of abscesses for infection control. This study describes in detail the process of rapid and precise US-guided drainage of GRA by an ultrasound interventionist through certain maneuvers and techniques.
Six US-guided drainage procedures were completed in four patients, and seven catheters were placed accurately in the abscesses with a 100% success rate. No intraoperative or postoperative complications such as bleeding and peripheral organ damage were observed, and the median time with catheters was 13 days (8-46 days).
The technique of real-time US-guided drainage of GRA can be performed safely in the ICU without the need to leave the ICU, greatly reducing risk.
本研究旨在描述和评估一种实时超声引导（US引导）引流技术，用于在重症监护病房（ICU）有效且安全地引流产气性肾脓肿（GRA）。
这项回顾性研究纳入了2021年9月至2023年9月期间入住三级护理中心ICU的4例GRA患者。这些患者均合并严重的全身感染，需要引流脓肿以控制感染。本研究详细描述了超声介入医生通过特定操作和技术对GRA进行快速精准的US引导引流的过程。
4例患者共完成6次US引导引流操作，7根导管均准确置于脓肿内，成功率达100%。未观察到术中或术后出血及外周器官损伤等并发症，导管留置的中位时间为13天（8 - 46天）。
GRA的实时US引导引流技术可在ICU安全实施，无需转出ICU，极大降低了风险。
