AB  - A 77-year-old woman presented with right flank pain radiating to the ipsilateral groin and associated nausea, consistent with renal colic. In the emergency department, a non-contrast CT scan revealed severe right-sided hydronephrosis but failed to demonstrate a calculus or ureteropelvic obstruction. The patient improved with fluids and followed up with a community urologist. Initial work-up with cystoscopy and ureteroscopy, voiding cystourethrogram and diuretic renography failed to deduce a diagnosis. At our hospital, we used a modified dynamic (supine and upright) Whitaker test in a novel fashion to diagnose nephroptosis, a rare hypermobility condition of the kidney.
