Urolithiasis is one of the most common causes of pain in pregnancy. Renal calculi can create a diagnostic and therapeutic challenge; left untreated, they can adversely affect maternal and fetal outcome. Although most cases of obstructive uropathy can be managed conservatively, some require relief of obstruction, usually by placement of a ureteral stent. We describe the use of ultrasound to identify an obstructed collecting system and provide guidance for placement of a double-pigtail ureteral stent in two pregnant patients. The technique used to manipulate the guide wire and stent into the renal pelvis under real-time ultrasound monitoring is discussed.
尿石症是孕期疼痛最常见的原因之一。肾结石会带来诊断和治疗方面的挑战；若不治疗，会对母婴结局产生不利影响。尽管大多数梗阻性尿路病病例可采用保守治疗，但有些病例需要解除梗阻，通常是通过放置输尿管支架。我们描述了如何利用超声识别梗阻性集合系统，并为两名孕妇放置双猪尾输尿管支架提供指导。本文讨论了在实时超声监测下将导丝和支架插入肾盂的操作技术。
