# A Case of Unilateral Renal Agenesis Detected by Abdominal Point-Of-Care Ultrasound

## TL;DR

A case study shows how abdominal point-of-care ultrasound detected a rare kidney condition in a child initially suspected of having intussusception.

## Contribution

Demonstrates the utility of POCUS in identifying congenital kidney anomalies during abdominal evaluations.

## Key findings

- POCUS ruled out intussusception and identified unilateral renal agenesis in a three-year-old girl.
- The case highlights the importance of checking for CAKUT during abdominal POCUS in children.
- Early detection led to appropriate nephrology follow-up for the patient.

## Abstract

As the interest in point-of-care ultrasound (POCUS) for investigating pediatric abdominal emergencies has been growing, an increasing number of literatures about abdominal POCUS has been published. We describe a noteworthy instance of a systematic approach using abdominal POCUS for detecting unilateral renal agenesis (URA) in previously healthy children with suspected intussusception. A previously healthy three-year-old girl was brought to our emergency department (ED) due to abdominal pain and bloody diarrhea. POCUS was performed to investigate the presence of intussusception. POCUS was able to rule out intussusception and detect URA. The investigation led the patient to a proper nephrology follow-up. When performing abdominal POCUS to evaluate gastrointestinal pathologies, it is important to pay attention to concomitant congenital anomalies of the kidney and urinary tract (CAKUT).
