Urinary Tract Dilation in the Fetus and Neonate
Mar 1, 2022 · Urinary tract dilation (UTD), previously known as hydronephrosis, is the most common congenital condition identified on prenatal ultrasonography. UTD can be physiologic and resolve spontaneously or can be caused by various congenital anomalies of the urinary tract, which can lead to renal failure if not treated properly.

Dec 1, 2014 · When UT dilation is detected postnatally (denoted as P), we recommend stratification of risk into three groups: low risk (UTD P1); intermediate risk (UTD P2); and high-risk (UTD P3) groups (Fig. 6). With UTD P1, the APRPD considered to be low risk for postnatal uropathies is 10 to <15 mm (Fig. 7 A and B). Again it should be emphasized that the ...
