URETEROCELE DENGAN DUPLIKASI URETER KOMPLIT

Ureterocele is a congenital distal ureter dilatation abnormality that formed like sac located intravesical or ectopic outside the normal anatomy location. The exact etiology of ureterocele is not yet known certainty, presumably due to the obstruction of the ureteral orificium during embryogenesis. There are 80% ureterocele associated with urinarius duplicating system. Radiological examination has an important role in the evaluation and diagnosis of ureterocele. We reported a case of 2 year 7 monthold girl admitted to the hospital with complaints of pain during urination experienced since 2 months ago. Routine urine examination showed leukocytes +++ / 500 cells / uL, blood: ++ / 80 cells / uL and bacteria (+). Ultrasound and CT scan examination showed the presence of intravesical cystic lesions which related to the left ureter. On BNO-IVP examination showed dilatation of left renal pelvicalyceal system that located inferiorly with drooping lily sign appearance, suspicion diagnosis of a bipelvic biureter. Hydronephrosis and hydroureter in lower moety and non function in upper moety. This finding was confirmed by the surgery result that the presence of two ureteric distal, ectopic ureterocele located on the urethral sphincter and another intravesical position.

Cystoscopic-Guided Laser Ablation of an Ectopic Ureterocele in a Female Dog

ABSTRACT An intact female dog was examined for urinary incontinence. A right-sided ectopic ureterocele with bilateral hydroureter and pyelectasis was diagnosed via ultrasonography, with concurrent complicated urinary tract infection. Following a course of antibiotics, cystoscopic-guided laser ablation was performed, and the dog remained continent at 3 mo follow-up. Cystoscopic-guided laser ablation provides a minimally invasive alternative to open surgery and is the treatment of choice in humans, and this case report demonstrates it is feasible in canine patients.

A rare case of bilateral obstructive megaureter with a giant uretal ureterocele on the left

The article discusses a case of 4-year-old patient with a bilateral obstructive megaureter of a non-functioning left kidney and with the opening of this kidney ureter into the urethra with extravasal location of a giant ureterocele. The malformation of the urinary system was accompanied by a comorbid disease of bronchopulmonary system in the form of tuberculosis of the lungs and intra-thoracic lymph nodes. At the age of one month, due to decompensation of the only functioning right kidney, urine was withdrawn by applying a ureterostomy. Later, a proximal lateral cutaneous ureterostomy was put because of social reasons (mother refused of her baby). In two months, the next step was performed - a ureterocystoneostomy by the Cohen’s antireflux technique. After a long-term treatment for tuberculosis in clinics of Tver and St. Petersburg, at the age of 4, the girl was operated on at the first surgical department at St-Petersburg State Pediatric Medical University. Laparoscopic nephroureterectomy on the left with conversion to lower-middle laparotomy and resection of the terminal part of the left ureter with a giant ectopic ureterocele as well as closure of the ureterocutaneostomy on the right were performed. After stabilization, the child was transferred to a children’s boarding school in Tver, and currently is supervised by pediatric urologists and TB specialists.

Computed tomographic and sonographic findings in a dog with duplex kidney, ureter duplex and ectopic ureterocele

A 5-month-old, male French bulldog was presented with a history of urinary incontinence. Abdominal ultrasound showed changes compatible with a ureterocele and a bilobed right kidney. Excretory computed tomographic urography was consistent with right-sided duplex kidney, ureter duplex and ectopic ureterocele. To the authors’ knowledge, this is the first description of a duplex kidney with an ectopic ureterocele diagnosed with ultrasound and contrast enhanced computed tomography in a dog. After the imaging diagnosis, a neoureterocystostomy was performed. In the follow-up examination the dog presented with mild incontinence which was treated medically using phenylpropanolamine.
