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: -There is an increased glomerular filtration rate (GFR), which peaks at about the 13th week of pregnancy and can reach levels up to 150% of normal.
Detailed explanation-3: -According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, because GFR decreases with age.
Detailed explanation-4: -The values for renal pelvis dilatation are taken from a number of studies. 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.
