The Society of Fetal Ultrasound has developed a grading system for hydronephrosis, initially intended for use in neonatal and infant hydronephrosis, but it is now used for grading hydronephrosis in adults as well:<ref>{{cite web|url=https://www.uptodate.com/contents/overview-of-fetal-hydronephrosis|title=Overview of fetal hydronephrosis.

* Grade 1 (mild) – Mild renal pelvis dilation (anteroposterior diameter less than 10 mm in fetuses<ref name="D'Addario2014" />) without dilation of the calyces nor parenchymal atrophy
* Grade 2 (mild) – Moderate renal pelvis dilation (between 10 and 15 mm in fetuses<ref name="D'Addario2014" />), including a few calyces
* Grade 3 (moderate) – Renal pelvis dilation with all calyces uniformly dilated. Normal renal parenchyma
* Grade 4 (severe) – As grade 3 but with thinning of the renal parenchyma
