This patient had right flank pain since a few months. But was not sure if he had a renal stone (calculus). The bladder ultrasound image appears normal.
The left kidney is normal. But not the right kidney- shows moderate hydronephrosis (back-pressure changes). The stone must be lower down somewhere....A difficult job to find this calculus, somewhere in the right ureter.. in a moderately obese patient.
Persistence and dogged determination to find the culprit, works. Sustained graded compression over the right flank, shows the dilated right ureter and the 17 mm. calculus in mid ureter.
Recorded an ultrasound video clip of the right mid ureteric calculus (arrows).
