Wilms tumor (WT) is the most common form of renal tumor in childhood. It has been known that a number of different clinical conditions and chromosome abnormalities accompany Wilms tumor [1,2]. Ochoa syndrome or urofacial syndrome (UFS) is a rare disorder characterized by dysfunctional urinary voiding, urinary tract infection, hydronephrosis, dysmorphic bladder, and dilatation of the ureter and pelvis [3-5]. Affected children are characterized by distinctive facial expression when they smile.
