Point of care kidney ultrasonography and its role in the diagnosis of urinary obstruction: a case report

Abstract Introduction: Ultrasonography (US) is a rapid, non-invasive and safe procedure that allows the nephrologist to obtain vital information to the bedside, as well as allows to guide the procedures for nephrology practice. Case report: Male patient, elderly with hypertension, diabetes mellitus and chronic kidney disease presents with infraumbilical protrusion that the Point of Care US (POCUS), performed by the nephrologist, proved to be a large bladder with a diverticulum. In addition, the US enabled the nephrologist to diagnose bilateral hydronephrosis, preservation of the cortico-medullary differentiation and echotexture of the right kidney, post-voiding urinary retention, urinary catheter placement and functional and morphological monitoring of the urinary tract after surgical correction of the infravesical obstruction. Conclusion: POCUS assessment of the renal tract may become the new standard of care among nephrologists by enabling the expansion of clinical information in a timely fashion, allowing faster resolution of cases and permitting the monitoring of the treatment done.

引言：超声检查（Ultrasonography, US）是一种快速、无创且安全的检查手段，可使肾内科医师在床旁获取关键临床信息，同时可指导肾内科临床操作。
病例报告：男性老年患者，合并高血压、糖尿病及慢性肾脏病，出现脐下膨隆。经肾内科医师实施的床旁超声（Point of Care US, POCUS）评估，证实为巨大膀胱伴憩室。此外，该超声检查协助肾内科医师诊断双侧肾积水，确认右肾皮质髓质分化及回声质地保留完好，发现排尿后尿潴留，指导尿管置入，并在膀胱下梗阻经外科矫正术后，对尿路进行功能与形态学监测。
结论：床旁超声（POCUS）对尿路的评估可成为肾内科医师临床护理的新标准，因其能够及时拓展临床信息，加快病例处置效率，并可对治疗实施效果进行监测。
