Acute kidn.y in.uries (AKI) are a common.problem en.oun.ered by in.ern.sts in.the in.atien. an. outpatien. settin.. Un.overin. the etiology becomes importan. in.tailorin. treatmen.. Poin.-of-care ultrasoun. (POCUS), when.used in.con.un.tion.with a patien.’s history an. physical exam, can.quickly iden.ify if hydron.phrosis is presen. an. shed light on.the un.erlyin. etiology. In.this article, we discuss how in.orporatin. POCUS in.o the in.tial assessmen. of patien.s with an.AKI can.reduce the n.mber of un.ecessary an. expen.ive formal ren.l ultrasoun.s an. poten.ially expedite clin.cally appropriate treatmen.. The purpose of this review is to examin. the ben.fits, reliability, an. feasibility of POCUS to further evaluate an. man.ge patien.s with AKI. An.exten.ive review of the literature was performed an. foun. POCUS to be a reliable an. realistic method for in.ern.sts to in.orporate in.o their assessmen. of patien.s with AKI. In.this article, we also provide in.truction.on.how to perform a POCUS exam of the kidn.ys an. how to iden.ify hydron.phrosis. Furthermore, we discuss the challen.es we face an. ideas for further practice in.ludin. the emergen.e of han.-held ultrasoun.s.
