Do You Need a CT? POCUS in First-Time Renal Colic

A 24-year-old man presents to urgent care with first-time renal colic. He is stable, tolerating oral intake, and has no signs of infection. Does he need a CT scan or emergency department referral?

In this Southern Medical Association case article, we explore how renal point-of-care ultrasound (POCUS) identified mild hydronephrosis at the bedside, allowing safe outpatient management without CT imaging or ED transfer. The article reviews key renal ultrasound findings, common pitfalls, evidence supporting a POCUS-first approach, and the broader impact on radiation exposure, healthcare utilization, and cost.

Learn how POCUS can help clinicians rapidly risk stratify patients with suspected renal colic while improving patient-centered care.
