URINARY Section I: Anatomy/Congenital Flashcards
Posterior Pararenal Space conatins
Only fat pads
Perirenal Space contains
Kidneys, proximal ureters, adrenals
Anterior Pararenal Space
Posterior Parietal Peritoneum
Lateroconal fascia
Anterior renal fascia (Gerota’s)
Posterior renal fascia (Zuckerkandl’s Fascia)
Transversalis fascia
between the anterior pararenal space and perirenal space
The Retromesenteric Plane (RMP)
between the perirenal space and posterior pararenal space
The Retrorenal plane (RRP)
Posterior Parietal Peritoneum
Gerota’s fascia
Posterior Renal Fascia (Zuckerkandl’s Fascia)
Combined Interfascial Plane
Perirenal Space pathologies
Renal mass
Renal hematoma
Renal abscess
Urine leaks (most are proximal)
Anterior Pararenal Space pathologies
Panreatitis - fluid collections (pseudocysts and stuff)
Duodenal hematoma
The kidney is surrounded by a thick capsule outlined by?
Echogenic perirenal fat
The echogenic perirenal fat is congitguous with the?
renal sinus, filling the middle kidney, separated by medullar pyramids
Focal bulge on the left kidney, which forms as the result o f adaptation to the adjacent spleen.
Dromedary Hump
Prominent columns of bertin
Normal variant in which hypertrophied cortical tissue located between the pyramids results in splaying of the sinus.
Junctional parenchymal defect
This is a “pseudo-scar” that looks like an echogenic line seen in the upper 1/3ofthekidney
Fetal Lobulation vs Reflux Scarring
Lobulation =
Renal surface indentations overlie the space between the pyramids
Fetal Lobulation vs Reflux Scarring
Scarring =
Renal surface indentations overlie the dilated / blunted calyces.
Tends to favor the upper and lower poles.
When renal agenesis is bilateral
Potter Sequence
Potter sequence
No Kidneys No Pee No Amniotic Fluid Hypoplastic Lungs
70% of women with unilateral renal agenesis have associated genital anomalies
Unicornuate uterus
20% of men with renal agenesis have =
Absent epididymis and vas deferens
Seminal vesicle cyst
IPSILATERAL
Mullerian duct anomalies including absence or atresia of the uterus + unilateral renal agenesis
Mayer-Rokitansky- Kuster-Hauser:
Lying Down Adrenal or “Pancake Adrenal” Sign
Elongated adrenal NOT molded by the adjacent kidney
Sign of congenital absence of the kidney
Pancake adrenal
