Point-of-care ultrasound (POCUS) has evolved in recent years in clinical practice, helping in early bedside diagnosis of important etiologies. Many medical schools and training programs are integrating POCUS into their curriculum. Especially with the technological advances of newer handheld ultrasound devices, POCUS has now become a component adjunct to clinical examination, in the clinic and bedside in critical care units. The diagnostic utility of POCUS lies both in early identification of critical kidney disease, and also extra-renal pathologies from a focused cardiac ultrasound, lung ultrasound, and integrated fluid assessment. There is a need to incorporate POCUS in training in pediatric nephrology and establish competency standard criteria. This review shall cover how POCUS helps in enhancing patient care in pediatric kidney disorders and critical children, and the recent advances.

床旁超声 (POCUS) 近年来在临床实践中不断发展，有助于重要病因的早期床边诊断。许多医学院和培训项目正在将 POCUS 整合到他们的课程中。特别是随着新型手持超声设备的技术进步，POCUS 现在已成为临床检查的辅助组件，在临床和重症监护病房的床边。POCUS 的诊断效用在于早期识别危重肾脏疾病，以及来自聚焦心脏超声、肺部超声和综合液体评估的肾外病变。需要将 POCUS 纳入儿科肾脏病学培训并建立能力标准。
