     Pediatric Radiology CasesMost likely etiology:

    unknown  

     
     Pediatric Radiology CasesHistory:

    Incidental findings in a 1.5 year-old boy with melena, no fever. Urine analysis was without findings (Transferral to abdominal sonography to rule out an invagination).  

     
     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease :

    A ureterocele is described as a cystic widening of the distal, submucosal running, intravesical segment of the ureter.
    One differentiates the ureteroceles according to the location of the afflicted ureterostium in intravesical (orthotopic) or extravesical (ectopic = in the bladder's neck or in the urethra).  

     
     Pediatric Radiology CasesRadiological findings:


    Ultrasound 1 <- view Ultrasound 1

    Ultrasound 1: urinary bladder with representation of the urine flow out of the ureters. Somewhat cystic-looking ostia (right > left) in an orthotopic situation in the trigonal area of the bladder.




    Ultrasound 2 <- view Ultrasound 2

    Ultrasound 2: urinary bladder shown longitudinally with ureterocele on the right.




    Ultrasound 3 <- view Ultrasound 3

    Ultrasound 3: Color doppler of the urinary bladder with proof of the flow of urine out of the right ostial mouth when ballooning the cele.




    Ultrasound 4 <- view Ultrasound 4

    Ultrasound 4: representation like the left ostium, only with slighter findings

     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other :

    Frequency: 0.2-0.3 in 1000 children. Ectopic ureteroceles are frequently associated with double kidneys (in that case, the cele is located in the upper region in 80%) and associated with vesicoureteral reflux. Orthotopic celes, on the other hand, can be normally found (90%)in just one kidney.

    Symptoms appear in ectopic celes usually in the 1st year, in orthotopic in much less common and are frequently found later: urinary tract infections, concrement formation, urosepsis, urine obstruction with reduced function of the kidney.
    A protruding ureterocele into the urethral lumen is the most frequent cause of an acute urine retention in newborns.
