ANATOMY

Detailed explanation-1: -A: Imaging in the transverse plane demonstrates an anterior-posterior renal pelvis diameter (APRPD) measuring < 7 mm, which is within the normal range for this gestational age.

Detailed explanation-2: -Normal measured GFR (mGFR) values of ∼120–130 mL/min/1.73 m2 have long been the referenced values for young adults but seem to be too high according to recent studies. Reference intervals are difficult to define because of the age decline of GFR, which is also observed in healthy subjects.

Detailed explanation-3: -Renal pelvis measurements change with gestational age. In general, ≥ 7 mm. is considered abnormal irrespective of gestational age. At <33 weeks, ≥ 5 mm. is generally considered the cutoff and a repeat measurement at ≥ 33 weeks is recommended. Neonatal follow up is recommended if the repeat measurement is ≥ 7 mm.

Detailed explanation-4: -Stage 3 CKD means you have an eGFR between 30 and 59 and mild to moderate damage to your kidneys. Your kidneys do not work as well as they should to filter waste and extra fluid out of your blood.
