1
What does supernumerary kidney look like on US?
An extra kidney will be found
- usually smaller
2
Where is the supernumerary kidney located?
Found above, below in front of or behind the normal kidney
3
What is the most common congenital anomaly?
Duplex collecting system
4
Duplex collecting system
Two separate collecting systems, ureters and their own ureteral orifice
5
Where do the ureters join and enter the bladder with an incomplete duplication?
Through a single ureteral orifice
6
What do patients of an increase risk of with a incomplete duplication?
Increased incidence of UPJ obstruction and uterus didelphys-duplex uterus
7
Incomplete duplication
Ureter draining the lower pole has a more perpendicular course through the bladder wall
8
What are you more prone to with an incomplete duplication? (2)
1. Reflux
2. Obstruction
9
What does obstruction of the ureter result in?
Cystic dilation of the intramural portion of the ureter
10
What does cystic dilation of the intramural portion of the ureter give rise to?
Ureteroceles
11
What are ureteroceles prone to?
Ureteral obstruction
- UTI’s
12
What is the treatment for ureteroceles?
Surgical
13
How do ureteroceles appear on US?
Round cyst like structure in the bladder
14
What does colour doppler do with ureteroceles?
Assess both jets
15
What may be present in the upper poles of ureteroceles?
Hydronephrosis
16
What is a common anomaly that causes a kink?
Ureteropelvic junction obstruction
- UPJ
17
Who is UPJ more common in?
Men
18
What happens with UPJ obstructions? (3)
1. Stones
2. Infection
3. Impaired renal function
19
What are 3 anomalies of bladder development?
1. Bladder agenesis
2. Bladder duplication
3. Bladder exstrophy
20
Bladder agenesis
No bladder
21
How are more infants with bladder agenesis?
Stillborn
22
What gender is more likely to survive bladder agensis?
Females
23
What are the 3 types of bladder duplication?
1. Complete/incomplete peritoneal fold separates 2 bladders
2. Complete/incomplete septum divides bladder
- may be multiple septa
3. Transverse band of muscle divides the bladder into 2 unequal parts
24
Bladder Exstrophy
Congenital absence of lower abdominal and anterior bladder wall
25
What increases with bladder exstrophy?
The incidence of bladder carcinoma
26
Aberrant vessels
During embryology, the kidney receives blood from the higher levels of the Aorta
27
When will aberrant renal arteries be present?
If supply from lower levels persist
28
Who is retrocaval ureter more common with?
Males
29
Retrocaval ureter
If the infrarenal IVC does not develop from the usual Supracardinal vein, the ureter will pass posterior to the IVC
- may become compressed as the ureter takes an unusual path before entering the bladder
