metanephric diverticulum. |

|
2. Renal agenesis :
occurs when the |
ureteric bud fails to develop, thereby eliminating the induction of metanephric vesicles and nephron formation.
|
|
|
|
2 types of renal agenisis
|
Unilateral renal agenesis
Bilateral renal agenesis |
|
|
|
1 Unilateral renal agenesis :
|
is relatively common (more common in males). This situation is asymptomatic and compatible with life because the remaining kidney hypertrophies.
|
|
|
|
2. Bilateral renal agenesis
|
▪is relatively uncommon
▪It causes oligohydramnios, causing compression of fetus, aka = ▪Infants with bilateral renal agenesis are usually stillborn or die shortly after birth. |
Potter syndrome
(deformed limbs, wrinkly skin, and abnormal facial appearance). |
|
|
occurs when there is a congenitally small kidney with no pathologic evidence of dysplasia =
|
Renal hypoplasia :
|
|
|
|
there is a disorganization of renal parenchyma with abnormally developed and immature nephrons. =
|
Renal dysplasia :
|
|
|
|
Renal dysplasia :
occurs when there is a = |
there is a disorganization of renal parenchyma with abnormally developed and immature nephrons.
|
|
|
|
occurs when one or both kidneys fail to ascend and therefore remain in the pelvis or lower lumbar area (i.e., pelvic kidney).
|
Renal ectopia :
In some cases, two pelvic kidneys fuse to form a solid mass, commonly called a = |
pancake kidney.
|
|
|
Ectopic kidneys take their blood supply from =
|
the vessels closest to them at the end of their limited ascent.
|
|
|
|
The most common type of renal fusion
|
horseshoe kidney.
|
|
|
|
A horseshoe kidney occurs when
|
the inferior poles of the kidneys fuse across the midline.
|
|
|
|
Normal ascent of the kidneys is arrested because the fused portion gets trapped behind the =
|
inferior mesenteric artery.
|
|
|
|
Kidney rotation is also arrested so that the hilum faces
|
ventrally
|
|

►Horseshoe kidney is found in =
►The prevalence of horseshoe kidneys in females with Turner Syndrome is about = |
1/600 people (1 in 400 people).
15%. ►It can be associated with trisomy ___ = |

Renal fusion :
The most common type of renal fusion is = |

Renal artery stenosis :
|
The stenosis may occur in the main renal artery (of segmental renal arteries).
