C	C123185	P3 Hydronephrosis	P3 Hydronephrosis		Postnatal Hydronephrosis with the following clinical findings: 1) calyceal dilation and the ureter are the same as those in UTD P2, 2) the renal parenchymal is thinned, has increased echogenicity and/or has decreased corticomedullary differentiation, or 3) the bladder is abnormal (wall thickening, ureterocele, posterior urethral dilation). Cases in which there are parenchymal abnormalities but the APRPD is less than 15 mm, are classified as UTD P3. (Adapted from: Hiep T. Nguyen, Carol B. Benson, Bryann Bromley, Jeffrey B.
