Aug 22, 2024 · The UTD classification system uses six ultrasound findings to describe the urinary tracts: anterior-posterior renal pelvic diameter (APRPD) calyceal dilatation, with distinction between central and peripheral calyces postnatally. renal parenchymal thickness, either normal or abnormal. renal parenchymal echogenicity, either normal or abnormal
The UTD classification system distinguishes antenatal from postnatal findings, where the higher numbers (UTD 1– 3) indicate greater risk of underlying or developing uropathy.

This pathway should be used to guide the evaluation and management of patients presenting with ultrasound findings of perinatal urinary tract dilation (UTD). This pathway should be used by pediatricians, neonatologists, and urologists to guide risk based evaluation and treatment based on pre-natal and post-natal ultrasound findings.

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 ...

The different elements of the Urinary Tract Dilation (UTD
We investigated how different elements of the UTD classification system predict differential renal function (DRF) and diuretic half-life (T½) on MAG3 scan in infants undergoing evaluation for prenatally detected UTD.

Oct 27, 2024 · Thus UTD A1 represents mild antenatal urinary tract dilation, and UTD P3 represents severe urinary tract dilation and/or other abnormalities, such as renal hyperechogenicity or a thick bladder wall after birth. Grading is based on the most severe finding.
