Endoluminal sonography using the IVUS is a minimally invasive procedure performed using a flexible 6.2F catheter with a 20 megahertz transducer that can easily be passed endoscopically to image the urethra, bladder, ureter and renal pelvis. In the current study, a woman patient in her third trimester of pregnancy with a renal pelvic stone and persistent colic was safely treated with placement of an indwelling ureteral stent. Because it is minimally invasive and does not require the use of roentgenograms, we believe the IVUS will be a useful tool to assist with the management of ureteral colic in patients who are pregnant in whom intervention is required.
使用血管内超声（IVUS）的腔内超声检查是一种微创手术，采用带有20兆赫换能器的6.2F柔性导管进行，该导管可轻松通过内镜传递以对尿道、膀胱、输尿管和肾盂进行成像。在本研究中，一名妊娠晚期患有肾盂结石和持续性绞痛的女性患者通过放置输尿管支架得以安全治疗。由于其微创且无需使用X线照片，我们认为IVUS将成为协助处理需要干预的妊娠输尿管绞痛患者的有用工具。
