Sonogram of a large, obstructing ureterocele in a patient with vesicoureteral reflux the thin rim of the ureterocele is best noted on the inferior most aspect of the bladder this ureterocele measured 4 cm in greatest dimension and is outlined by contrast material in image 4. Ureterocele a reformatted coronal image from a ct urogram demonstrates a partially duplicated collecting system on the left side with two ureters (black and white arrows) that join at the pelvic inlet and insert as one ureter into the bladder.
Ureterocele pictures, symptoms, causes, diagnosis, treatment, ultrasound learn all about ureterocele and its causes, symptoms and treatment options ureterocele is a dilation of the area where the ureter inserts into the bladder.
One classification scheme is based on location of the ureterocele in regards to the entry of the ureter into the bladder ureteroceles can be located normally within the bladder (orthotopic) or located within the bladder neck and urethra (ectopic.

Extravesical ureterocele (~75%) also known as ectopic ureterocele 4,6 almost always associated with a duplicated collecting system and the result of abnormal embryogenesis there is an abnormality in the early development of the intravesicular ureter, the ipsilateral kidney and its collecting system 1 it is significantly more common than the simple type.
The ureterocele in this case was located in a normal anatomic location and was classified as orthotopic animal specialty group: the etiology of the development of ureteroceles is unknown there have been many theories including an obstructive etiology with subsequent dilation which was first proposed in 1927.
Dogs with ectopic ureters usually present with urinary incontinence and are predominantly young females ectopic ureter is thought to occur because of disruption in normal embryogenesis and is commonly associated with other abnormalities of the urogenital tract diagnosis is usually made with contrast radiography and ultrasonography. The field of radiography has different modalities and studies that use medical imaging that can diagnose and watch the condition of ureteroceles at nineteen weeks pregnant, emily was told that trent had severe hydronephrosis in his right kidney found on the ultrasound (davis, 2014.
