A middle-aged man was seen in the nephrology clinic after a recent hospitalization for acute pyelonephritis and acute kidney injury (AKI) requiring a few sessions of dialysis. AKI was thought to be due to acute tubular injury in the setting of infection and concomitant NSAID use. CT at the time of admission showed mild left hydronephrosis and hydroureter.

Point of care ultrasound was performed in the clinic by medical student who thinks there is persistent mild left hydroureter. Is he/she right?
