The lateral view is the best view for measuring your sacral index. There is less alteration. On the AP view, it always tends to be a little bit smaller than it does on the lateral view.

Anorectal Malformation
So you know that there is urine mixing with meconium, and that tends to calcify fairly quickly. So this patient has a rectal GU connection.

Anorectal Malformation
When you see a hemisacrum, you have to start thinking about curavenous triad. And you have to presume that there is a presacral mass there.
quote ·
Cloaca
The combination of those three components in a female should make you begin to at least consider the diagnosis of cloacal malformation.
quote ·
Cloaca
Perforation during colostography with hyperosmotic contrast (e.g., cystoconray, ~400 mOsm) causes immediate fluid shift and peritonitis requiring emergent IV fluids and surgical consultation.

Colorectal / ARM & Hirschsprung
Cystoscopy by an experienced urologist can identify the fistula in approximately 9 out of 10 cases, though prior surgical experience found only 3 out of 10 fistulas visible cystoscopically

Anorectal Malformation Radiology: Pediatric Colorectal Controversies 2014
Statement
In females, prenatal ultrasound showing bilateral hydronephrosis, small bladder, and dilated vagina suggests cloaca.

Quotation
The combination of those three components in a female should make you begin to at least consider the diagnosis of cloacal malformation.
Open
Statement
Calcified enteroliths in the GI tract on neonatal KUB indicate urine mixing with meconium, suggesting a recto-GU fistula at least at the bulbar level or higher.
Open
Quotation
So you know that there is urine mixing with meconium, and that tends to calcify fairly quickly. So this patient has a rectal GU connection.
Open
Statement
On fetal MRI, the distal rectum should extend at least 10 mm below the bladder neck in the second trimester, up to 20–24 mm in the third trimester; high position suggests ARM.
Open
Statement
After 20 to 24 weeks gestation, T1 hyperintensity of meconium within the colon should be visible on fetal MRI; loss of T1 hyperintensity and bright T2 signal suggests urine mixing.
Open
Quotation
When you see a hemisacrum, you have to start thinking about curavenous triad. And you have to presume that there is a presacral mass there.
Open
Statement
When hemisacrum is seen in a patient with anal malformation, Currarino triad must be assumed and presacral mass must be looked for.
Open
Quotation
The lateral view is the best view for measuring your sacral index. There is less alteration. On the AP view, it always tends to be a little bit smaller than it does on the lateral view.
Open
Statement
For sacral ratio measurement, a true AP pelvis (not angled sacral view) and lateral pelvis are required; the lateral view is more accurate.
Open
Statement
Normal sacral ratio ranges from 0.6 to 1.0; below 0.3 predicts very low likelihood of continence.
Open
Statement
Cross-table lateral (invertogram) must be performed after 24 to 36 hours to allow enough air and pressure to show the true level of the distal rectal pouch.
Open
Quotation
You really can't do this and get an accurate knowledge or an accurate representation of where that distal rectum really is unless you do this after 24 to 36 hours.
Open
Statement
It is difficult to distinguish radiologically between prostatic and bulbar urethral fistulae; the bend in the urethra is used as an approximate landmark.
Open
Quotation
The key is making sure that you have very good pressure and you have a good length of colon there for the surgeons.
Open
Statement
Distal colonic segments that are very dilated and atonic are at higher risk of perforation during colostography due to Laplace's law (thin wall, high pressure).
Open
Statement
Perforation during colostography with hyperosmotic contrast (e.g., cystoconray, ~400 mOsm) causes immediate fluid shift and peritonitis requiring emergent IV fluids and surgical consultation.
Open
Statement
Iso-osmotic contrast is now preferred for distal colostography to avoid fluid shifts if perforation occurs.
Open
Quotation
The problem is the contrast agent we use now where we are is a isosmotic contrast. As a result of that, we changed. And we use a contrast agent that's very dense, but it's isosmotic to body fluids. So if it were to get into the perineum, there would not be any fluid shifts.

ARMs in Male Patients: Pediatric Colorectal Controversies 2014
Statement
Combining distal colostography with VCUG in the same setting provides complete anatomical information; the colostogram is done first, contrast removed, then VCUG performed
Open
Statement
Distal colostography requires both lateral and oblique/AP views with full distention and exact measurements to adequately assess fistula location and rectal length
Open
Statement
Bladder-neck fistulas are distinguished from prostatic fistulas by location above the angle of the urethra; prostatic fistulas are at or below the urethral angle
