一种用于增强肥胖输尿管远端结石患者体外冲击波碎石术的新型辅助装置

摘要(中文译文)

肥胖会显著增加患尿路结石的风险，尤其是输尿管远端结石，这可能会使体外冲击波碎石术（SWL）的治疗复杂化。在肥胖患者中，皮肤和结石之间的距离往往超过有效冲击波范围，从而降低了SWL的疗效。这项研究提出了一种创新的SWL辅助装置，旨在通过使用直肠或阴道等自然身体通道来缩短皮肤和结石之间的距离，从而应对这一挑战。本研究纳入了三名患有输尿管远端结石的肥胖患者，他们最初因皮肤与结石之间的距离过大而不适合常规SWL。在SWL期间，通过自然身体通道使用辅助装置来减少皮肤与石头的距离。通过术后影像学评估临床结果。进行了描述性分析。在三名患有远端输尿管结石的肥胖患者中，使用该装置可以有效地进行体外冲击波碎石术，随访成像中没有检测到残余结石。该设备已在中国获得专利（专利号：ZL 2020 2 2018950.0），目前正在进行大规模临床试验，以进一步评估其安全性和有效性。这一进展为以前无法接受有效SWL治疗的肥胖患者提供了一种有前景的解决方案。不适用。

Abstract

Obesity significantly increases the risk of developing urinary tract stones, particularly distal ureteral stones, which can complicate treatment with extracorporeal shockwave lithotripsy (SWL). In obese patients, the distance between the skin and the stone often exceeds the effective shockwave range, reducing SWL efficacy. This study presents an innovative SWL assistive device designed to address this challenge by using natural body passages such as the rectum or vagina to shorten the distance between the skin and the stone. Three obese patients with distal ureteral stones who were initially unsuitable for conventional SWL due to excessive skin-to-stone distance were included. An assistive device was used via natural body passages to reduce the skin-to-stone distance during SWL. Clinical outcomes were assessed by postoperative imaging. Descriptive analysis was performed. In three obese patients with distal ureteral stones, the use of the device allowed SWL to be performed effectively, with no residual stones detected on follow-up imaging. The device has been patented in China (Patent No.: ZL 2020 2 2018950.0) and is undergoing larger-scale clinical trials to further evaluate its safety and efficacy. This development offers a promising solution for obese patients who were previously unable to undergo effective SWL treatment. Not applicable.
