The CUSA is a unique modality for precise removal of tissue. This ultrasonic scalpel represents a major technical advance in surgery by providing a small handpiece device that can selectively remove tissue in a controlled manner. The usefulness of this modality in removing parenchymal tissue while sparing vascular or ductal structures is outstanding. Laboratory and clinical experience have demonstrated that utilization of this scalpel, particularly in vascular organs and lesions, provides the surgeon with increased visibility, reduced bleeding, and shorter operating time. Our application of this instrument in the performance of renal surgery in dogs as well as in the clinical setting has been well documented. Its future application as a surgical tool in the armamentarium of the urologist is uncertain and awaits the outcome of future studies.
超声外科吸引器（CUSA）是一种用于精确切除组织的独特设备。这种超声手术刀通过提供一种小型手持装置，能够以可控方式选择性地切除组织，代表了外科手术的一项重大技术进步。这种设备在切除实质组织同时保留血管或导管结构方面的效用非常突出。实验室和临床经验表明，使用这种手术刀，尤其是在血管性器官和病变中使用，能为外科医生提供更好的视野、减少出血并缩短手术时间。我们将该器械应用于犬类肾脏手术以及临床实践的情况已有充分记录。其作为泌尿外科医生手术器械库中一种手术工具的未来应用尚不确定，有待未来研究的结果。
