Diagnosis of Posterior Urethral Valves in an Infant Using Point-of-Care Ultrasound.

This case describes a 7-week-old male infant presenting with vomiting and decreased urine output. Initial point-of-care ultrasound (POCUS) demonstrated a normal pylorus; however, assessment of bladder volume revealed the problem. The bladder was distended with a thickened, trabeculated wall and there was bilateral hydroureter, consistent with bladder outlet obstruction. ⋯ A voiding cystourethrogram confirmed the diagnosis of posterior urethral valves which were eventually ablated by urology. To our knowledge, this is the first case report of POCUS leading to a diagnosis of posterior urethral valves in an infant. This case highlights how POCUS can expedite evaluation of decreased urine output.

AbstractThis case describes a 7-week-old male infant presenting with vomiting and decreased urine output. Initial point-of-care ultrasound (POCUS) demonstrated a normal pylorus; however, assessment of bladder volume revealed the problem. The bladder was distended with a thickened, trabeculated wall and there was bilateral hydroureter, consistent with bladder outlet obstruction. Renal POCUS revealed bilateral hydronephrosis and perinephric fluid collections consistent with calyceal rupture. A voiding cystourethrogram confirmed the diagnosis of posterior urethral valves which were eventually ablated by urology. To our knowledge, this is the first case report of POCUS leading to a diagnosis of posterior urethral valves in an infant. This case highlights how POCUS can expedite evaluation of decreased urine output.Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.
