Overview
According to the society of Fetal Urology, hydronephrosis is graded into 4 on the basis of ultrasound findings
Classification
- According to the society of Fetal Urology and alternative hydronephrosis grading system (AGS) hydronephrosis is graded into 4 on the basis of ultrasound findings[1][2][3][4][5]
| Grade 0 | No renal pelvis dilation | Anteroposterior diameter of less than 4 mm in fetuses |
| Grade 1 | Mild renal pelvis dilation | Anteroposterior diameter less than 10 mm in fetuses |
| Grade 2 | Moderate renal pelvis dilation | Anteroposterior diameter between 10 and 15 mm in fetuses |
| Grade 3 | Renal pelvis dilation along with all calyces dilatation | |
| Grade 4 | Renal pelvis dilation along with all calyces dilatation
with thinning of the renal parenchyma |
