The obliterated umbilical artery persists as this paired structure in adults
Medial umbilical ligaments
Choice for diversion in infant with myelomeningocele, bilateral grade 5 VUR and thickened bladder, elevated LPP
Cutaneous vesicostomy
Two remnants of the paramesonephric (Mullerian) duct in males
Appendix testis and prostatic utricle (MIS produced by sertoli cells leads to regression)
A potentially serious side effect from treating nocturnal enuresis with desmopressin
Hyponatremia/seizure
The most likely diagnosis for an infant with a large abdominal mass that regresses over the first year of life
Neuroblastoma
Ileocecal artery (supplies ileum, cecum, appendix)
Choice for diversion in 2 month old with congenital primary obstructive megaureter and urosepsis despite antibiotic prophylaxis
Cutaneous ureterostomy
The ureteral bud arises off of this structure
Mesonephric (Wolffian) duct
The risk of developing this condition is why Bactrim is condtraindicated in babies less than 2 months of age
Kernicterus (sulfonamides may unbind bilirubin from albumin, raising serum bilirubin)
The most effective radioisotope for identifying renal scarring
DMSA (binds to proximal tubular cells for several hours, only 10% is excreted in urine)
The abdominal muscle layer contiguous with cremasteric muscle
Internal oblique
Choice for reconstruction in infant with duplicated system, functional parenchyma, ectopic upper pole ureter with hydroureteronephrosis and recurrent UTIs
Ipsilateral ureteroureterostomy
Differentiation of the indifferent gonad to become the testis is dependent on this gene on the Y chromosome
SRY gene
This antidepressant has a 50% success rate for bedwetting, however overdose can result in fatal cardiac arrhythmias
Imipramine
Generally, pediatric ultrasound transducers use a ___ frequency compared to adults
Higher (higher frequency = shorter wavelength = less penetration, better for superficial structures)
Loss of sensation in the anterior upper thigh after laparoscopic varicocelectomy is due to injury to this nerve
Femoral branch of the genitofemoral nerve
Preferred repair for SFU grade 4 hydronephrosis and UPJO with an intrarenal pelvis and 3cm segment of stenotic ureter
Ureterocalicostomy
Of the three embryonic kidneys, the one that persists to become the definitive kidney
Metanephros (pronephros regresses by 5th week, mesonephros regresses by 5-12th week)
The most well-established late toxicity of doxorubicin, the third chemotherapeutic agent added on for stage IV or higher Wilms' tumor
Cardiotoxicity / cardiomyopathy (>20%)
(other agents: vincristine and dactinomycin)
This finding (exhibit F) in a newborn girl with upper pole hydronephrosis
Prolapsed ureterocele
Spinal cord imaging in an infant with a sacral dimple and incomplete emptying may reveal a conus medullaris terminating below this spinal level
L3
(normal is between L2-L3 in infancy, then L1-L2 in older child and adult)
Choice for continent catheterizable channel in a child with neurogenic bladder and prior appendectomy
Monti (reconfigured ileum)
Vesicoureteral reflux
This antibiotic should not be given to newborns less than 1 month due to risk of hemolytic anemia
