Kidneys 3 Flashcards
types of cystic kidney diseases (4)
Multicystic Dysplastic Kidney
ARPKD
ADPKD
Medullary Cystic Disease
Multicystic Dysplastic Kidney caused by
Ureteral obstruction in utero
what results from Multicystic Dysplastic Kidney
terminal tubules become cysts
Kidney looses it’s function
bilateral Multicystic Dysplastic Kidney similar to
bilateral renal agenesis
classic appearance of Multicystic Dysplastic Kidney
“bunch of grapes” appearance
is Multicystic Dysplastic Kidney one or multiple cysts
either
do cysts communicated with Multicystic Dysplastic Kidney
no
treatment for Multicystic Dysplastic Kidney
Surgical removal— If the kidney is large
With time kidney stops producing urine, size of cysts decrease and kidney may no longer be visible
ARPKD aka
Infinitile PKD or Autosomal Recessive
Sono of infantile PKD
Both side Large kidneys Diffusely echogenic* echogenic foci* Pyramids not seen* Associated with hepatic fibrosis
is infantile PKD bilateral or uni
bilateral with Symmetrically enlarged kidneys
Cysts are microscopic (tubular dilatation)
ADPKD aka
Adult PKD
Adult PKD is bilateral or uni
either
Adult PKD may occur in _______ and what size of cysts
neonates
cyst size range 0.1-5mm
ADULT PKD CYST MAY BE FOUND IN (5)
liver, panc., lungs, spleen, gonads.
2 types of medullary cystic disease
medullary sponge kidney and juvenile nephronophthisis
what causes echogenic pyramids in medullary sponge
calcium deposits
4 neoplasm of the kidney
Wilms Tumor*
Nephroblastomatosis
Mesoblastic Nephroma
Angiomyolipoma
three important things to determine when scanning abdominal mass
- origin of the mass
- extent of the mass
- metastases
wilms tumor aka
nephroblastoma
most common renal tumor in ped patients
wilms
Wilms tumor can invade (4)
lymph nodes
retroperitoneal
renal veins
IVC
Wilms tumor mets to
liver and lungs
wilms tumor bi or uni
may be bilateral ( i think this means most f the time its uni tho)
clinical signs of Wilms tumor
Palpable mass Non-specific symptoms Pain Fever Malaise Weight loss Hematuria Hypertension
sono appearance of wilms
Large
Well-circumscribed
