What does MCDK look like on US

Multiple cysts varying size
Loss of sinus

1

Fetus modifies fluid volume after

20 wks

2

Oligohydramnios reasons

Renal anomaly
IUGR
PROM
Fetal demise
Post term Gestation

3

Bilateral renal agenesis

Most severe GU anomaly
Severe oligohydramnios
Fail to ID kidneys
Fail to ID bladder
Fail to ID renal arteries
Lethal

4

Potter's Syndrome

Bilateral renal agenesis, oligo,IUGR
Pulmonary hypoplasia
Facial anomalies: flat parrot nose, sm chin, low set ears
Malformed extremities

5

Unilateral agenesis

Normal fluid
Adrenal takes on reniform shape & hard to ID
Bladder seen

6

Hydronephrosis

Renal pelvis > 5 mm 15-20 wks
>8 mm 20-30wks
>10 mm > 30 wks

Tri 21 has mild dilation

7

UPJ

MC cause of congenital hydro due to obstruction
Hydro in kidney only

Assoc: contralateral MCDK, agenesis

8

UVJ

Dilated upper pole kidney and pelvis

May be due to ureter duplication with ureterocele

9

PUV

MC cause of bladder obstruction
Males
Hydro both kidneys, ureters, keyhole bladder, oligohydramnios

10

Urethral atresia

Bilateral hydro, enlg bld, oligohydramnios, cystic renal Dysplasia over time.

11

Prune Belly Syndrome / Eagle Barrett

Deficient abd muscle
Cryptorchidism
GU anomalies

Big belly

12

ARPKD

Enlg kidneys, spongy, tiny cyst, Echogenic
Bilateral
No bladder
Severe oligo/anhydramnios

13

MCDK

MC cystic renal Dysplasia
Unilateral
Contralateral UPJ or agenesis

Multiple cysts varying size
Loss reniform shape & sinus differentiation
Inc echoes between cysts

14

Cystic Renal Dysplasia

Occurs with early obstruct of GU
Dec renal function/bilateral
Cyst form over time

15

Meckel Gruber

Cystic kidneys, encephalocele, polydactyly

16

Beckwith Wiedeman Syndrome

Polyhydramnios
Omphalocele
Macroglossia big tongue
Hemi Hypertrophy
